Soosaarayaasha taleefannada casriga ah waxay sameynayaan wax kasta oo ay awoodaan si ay u keenaan astaamo cusub oo xiiso leh. Qaarkood way ka guul badan yihiin kuwa kale, qaar waxay u joogaan oo kaliya ujeedooyin suuqgeyn. In kasta oo tirada sii kordheysa ee taleefannada casriga ah ay muujinayaan duubista fiidiyowga 8K, runtii ma awood faa'iido leh miyaa, mise waa uun faw? Maqaalkan, waxaan uga jawaabi doonaa dhowr su'aalood oo laga yaabo inaad qabto oo ku saabsan duubista muuqaalka. duubista 8K ma mudan tahay in la isticmaalo? Waa maxay xalka ugu fiican ee duubista fiidiyowga ee taleefannada casriga ah? Anoo ku qalabaysan Samsung Galaxy S22 Ultra^{(Samsung Galaxy S22 Ultra)} ee cajiibka ah , waxaan falanqeeyay xaalado duubitaan oo kala duwan waxaanan diyaar u ahay inaan soo bandhigo natiijooyinkayga:

Ka weyn, ka wanaagsan, sax?

Kahor intaanan ka hadlin cabbirka muuqaalka iyo tayada, aan marka hore idhaahdo sidan: sawir qaadista, inta badan ee xallinta, ayaa fiican. Haddii aad heli karto tayada cayriin (aan la farsamayn) la mid ah, sawirada xallinta sare ayaa u roon sababta cad oo ay ku jiraan macluumaad dheeraad ah. Tani waxay ka dhigan tahay inaad soo dhawayn karto, dib u habayn karto oo aad hoos u dhigi karto iyaga ilaa xal hoose iyadoo la ilaalinayo tayada. Tusaale ahaan, hoos u dhigista sawirka 4K ilaa 1080p waxay had iyo jeer soo saari doontaa natiijo ka fiican tii lagu toogtay 1080p. Hadda, u gudub fiidiyowyada…

TALO:^(TIP:) Haddii aad ku wareersan tahay shuruudaha sida 4K ama 1080p, waxaan kugula talineynaa maqaalkan: Waa maxay macnaha 720p, 1080p, 1440p, 2K, 4K?^{(What do the 720p, 1080p, 1440p, 2K, 4K resolutions mean?)}

1. Tayada sawirka iyo habaynta

U guurista fiidiyowyada, isla qodobka guud ahaan waa run sidoo kale: dhammaan ujeeddooyinka iyo ujeeddooyinka, adeegsiga xallinta sare ee duubista fiidiyowga waxay soo saartaa tayada wanaagsan ee alaabta la dhammeeyey, dhammaan waxyaabaha kale waa siman yihiin^{(all other things being equal)} . Laakiin taasi waa waxa: taleefannada casriga ah, marka la duubo fiidiyowyada, laga bilaabo barta, goobaha kale maahan kuwo siman. Xataa marka aad tooganayso muqaal leh dhammaan agabka caawiyayaasha ah ee dansan (sida AI, HDR , iwm.), talefanka casriga ahi waxa uu sameeyaa habayn culus si uu muuqaaladu u ekaado. Waxaa jira meel macaan oo tan ah: haddii aad aad u hooseyso xallinta, fiidiyowgu wuxuu u ekaan doonaa pixelated, laakiin dhinaca kale, adoo isticmaalaya xallinta ugu badan ee uu dareemuhu qaban karo wuxuu kaa qaadi doonaa sifooyin badan oo farsameyn ah. Tani waa run xitaa aaladda calanka sida Galaxy S22 Ultra: duubista 8K waxay inta badan soo saartaa muuqaalo aan ka roonayn kuwa lagu toogtay 4K. Dhab ahaantii, qaar ayaa laga yaabaa inay ku doodaan inay u muuqdaan kuwo ka sii liita, jilicsan, iyo waxyaabo badan oo farshaxan ah.

Meesha macaan ee Samsung Galaxy S22 Ultra , marka loo eego aragtidayda, waa duubis muuqaal ah oo 4K ah, maadaama tayada duubistu ay aad u fiican tahay, oo hoos loo dhigo 1080p waxay keeni doontaa muuqaal tayo wanaagsan oo ka fiican hal tallaal oo ah 1080p:

Iftiin hooseeya, farqiga ayaa xitaa muuqda. Fiidiyowyada 8K waa madow, oo leh buuq badan, halka fiidiyowyada 4K iyo 1080p ay ka faa'iideysan karaan awoodda farsamaynta buuxda ee chipset-ka iyo afarta kamaradood ee ku yaal dhabarka dambe ee Samsung Galaxy S22 Ultra .

Dabcan, tani maahan kiiska taleefannada casriga ah ee kale. Qaarkood waxay soo saaraan fiidiyowyo tayo fiican leh marka lagu duubo 8K, laakiin mid ka mid ah arrimaha ugu muhiimsan ee qaabkan ayaa bilaabaya inuu qaabeeyo: maadaama 8K tignoolajiyada casriga ah aysan weli qaan gaarin, natiijooyinka waa la garaaci karaa ama waa la seegi karaa.

2. Xasilinta

Tan iyo markii aan sheegay hab-samaynta fiidiyaha tooska ah, mid ka mid ah hababka ugu muhiimsan ee Galaxy S22 Ultra u isticmaalo si loo hagaajiyo tayada muuqaalkaaga waa isku darka xasilinta sawirka indhaha ( OIS ) iyo xasilinta sawirka elektiroonigga ah ( EIS ). Marka la soo koobo, OIS waxay ku shaqeysaa iyadoo si jir ah u dhaqaajineysa dareeraha kamarada si ay u magdhabiso dhaqdhaqaaqa kamarada, halka EIS ay isticmaasho algorithms-ka xariif ah iyo abuurka sawirka si loo gaaro natiijooyin isku mid ah. OIS waxay muhiim u tahay sawirada, laakiin fiidiyowyada, EIS aad ayay uga muhiimsan tahay, qayb ahaan sababtoo ah waxay u falcelisaa si dhakhso ah. Qaar ka mid ah taleefannada casriga ah, sida Realme GT2 Pro, 8K fiidiyowgu ma xasilin, taas oo si cad u saameynaysa tayada duubista. Calannada kale, sida Samsung Galaxy S22 Ultra , xasilintu waa mid aad u fiican, waxayna si fiican ugu shaqeysaa dhammaan qaraarada.

Si kastaba ha noqotee, Galaxy S22 Ultra wuxuu leeyahay muuqaal la yiraahdo Super Steady Video ( SSV ) kaas oo loo qoondeeyay fiidiyowyada 1080p. Waxaad ka hawlgelin kartaa adiga oo aadaya qaybta Video -ga ee app-ka kamarada^{(Camera )} oo aad taabto calaamadda gacanta ee qaybta sare ee shaashadda (iyada oo loo malaynayo in talefanka gacanta uu ku jiro jihaynta sawirka).

Taabo summadan si aad awood ugu siiso Fiidiyowga Joogtada^{(Super Steady Video)} ah ee Samsung Galaxy S22 Ultra

Si loo bixiyo xasilinta heerkan, Galaxy S22 Ultra waxay isticmaashaa kamarada aadka u ballaaran iyo xallinta 1080p kaliya, oo leh kala duwanaansho zoom ah 0.6 ilaa 1.0. Maaddaama ultrawide-ku uu u toogto asal ahaan 4K oo uu leeyahay muuqaal aad u weyn (120 darajo oo ka soo horjeeda 85 ee kamaradda ugu weyn, asal ahaan ku siinaya 0.6 zoom), xaddidaya SSV ilaa ultrawide oo leh 1080p xallin iyo heer xaddidan oo zoom ah ayaa siinaya casriga ah qol aad u badan oo lagu gooyo, dib u habeyn iyo hagaajinta sawirka iyada oo aan tayada lumin.

Waxa ugu muhiimsan ee laga qaadanayo waxaas oo dhan? Si aad u hesho xasilinta ugu fiican, waxaad u baahan tahay inaad haysato xalin badan oo dusha sare ah. Markaa, toogashada 8K ma fiicna haddii aad u baahan tahay sawirro sugan oo aad u sarreeya (ugu yaraan, maaha tignoolajiyada casriga ee maanta).

3. Mooshin la'aan

Marka xigta, waxaan curyaamiyay Super Steady Video ( SSV ) oo waxaan toogtay laba fiidiyow oo aad u gariiraya, oo leh dhaqdhaqaaq gacmeed degdeg ah, mid 1080p/30fps ah iyo mid 8K/24fps. Aragti ahaan, labaduba waa inay ka faa'iidaystaan ​​heerka OIS iyo EIS . Waa kan muuqaalkii aan ku toogtay 8K/24fps oo leh zoom 1 ah (taas oo u dhiganta 1.6 zoom ee 4K iyo 1080p). Fadlan^(Please) ogow in YouTube- ku uu ku cadaadiyo fiidiyowyada:

Fiidiyowga hoose waxaa lagu duubay 1080p/30fps oo leh zoom qiyaastii ah 1.6 si uu u dhigma heerka zoom ee ay isticmaashay kamaradu qaabka 8K, iyo haddii aad si dhow u eegto, shay soo jiidasho leh ayaa soo baxaya.

Hagaag^(Okay) , xasilinta sawirka caadiga ah waxay si fiican u shaqeysaa labada xaaladood, wax faallo ah ma jiraan. Laakiin inkasta oo sawirada taagan ay si cad u leeyihiin tafaasiil badan (xitaa lagu arkay 1080p), ma jiro farqi la garan karo oo u dhexeeya 8K iyo duubista 1080p marka sawirku socdo. Sidee taasi noqon kartaa? Sawirka soo socdaa waxa uu is barbar dhigaya jir ka kooban blur dhaqdhaqaaqa duubis kasta.

Isbarbardhigga qaabka weli (1080p vs 8K)

Tayada qallafsanaanta dhaqdhaqaaqa waxay ahaanaysaa isla sideedii, oo markaa fiidiyowyada leh dhaqdhaqaaq badan uma arkaan wax horumar ah xagga tayada ilaa inta fps-yadu ay isku mid yihiin^{(Motion blur quality stays roughly the same, and thus videos with lots of movement see no improvement in quality as long as the fps are similar)} (Anigu waxaan ka dhigayaa mid aad u fudud, maaddaama xawaaraha shutter-ka iyo arrimo kale ay sidoo kale muhiimad weyn leeyihiin halkan). Tani waxay ka dhigan tahay, halka 8K ay faa'iido u leedahay sawir qaadista, marka aan ka hadlayno duubista fiidiyowyada, xaaladdu si weyn ayay isu beddeshaa. Hagaajinta tayada fiidiyowyada leh dhaqdhaqaaq badan ayaa lagu gaari karaa oo keliya iyadoo la kordhinayo qaab-dhismeedka (wax badan), si loo baabi'iyo qulqulka dhaqdhaqaaqa. Laakiin marka blur dhaqaaqu meesha ka baxo, muuqaalku wuxuu u ekaa mid aan dabiici ahayn.

4. Habaynta awooda, nolosha batteriga, iyo kulaylka

Duubista fiidiyowyada 8K waxay batteriga ka saartaa si ka dhaqso badan, aynu nidhaahno, toogashada 1080p. Sababuhu waa cad yihiin: xog badan oo la qabtay waxay ka dhigan tahay xog badan oo la farsamaynayo, isticmaalka processor-ka oo aad u sarreeya, iyo isticmaalka tamar badan. Si aan u caddeeyo fikradayda: toogashada fiidiyowga 5-daqiiqo ah ee 1080p / 30fps waxay qaadatay 2% batteriga iyada oo lagu toogtay fiidiyow isla goobta, oo leh goobo isku mid ah, laakiin leh 8K / 24fps, ayaa nuugay 3%. Waxay ku dhowdahay 50% ka badan, taasina waxay samayn kartaa farqi haddii aad duubi lahayd fiidiyowyo dheer ama badan. Ma aha oo kaliya, laakiin inta lagu jiro tijaabada, Samsung Galaxy S22 Ultraxitaa wuxuu iiga digay inaan 8K ku toogto in ka badan 5 daqiiqo si aan uga fogaado kulaylka. Oo runtii, dhamaadka 5 daqiiqo ee duubista 8K, qalabku wuxuu ahaa mid aan fiicneyn. Kuleyl badan ayaa ka dhigan in batari badan oo sii xumaanaya waqti ka dib sababtoo ah kulaylku waa cadowga baytariyada.

5. Cabbirka faylka

Midkani waa mid iska cad, laakiin si kastaba ha ahaatee, waan sheegi doonaa si kastaba ha ahaatee: xallinta sare, way sii weyn tahay faylka natiijada. Waa run sawirada, laakiin waa dhibaato dhab ah marka ay timaado muuqaalada. Oo ma aha oo kaliya sababtoo ah booska bannaan ee casriga ah (inkasta oo taasi ay tahay dhibaato sidoo kale maadaama taleefanno badan oo casriga ah aysan haysan kayd la fidin karo). Maya, waxay leedahay wax badan oo ku saabsan wareejinta faylka. Kaliya isku day inaad saaxiib u dirto muuqaal 1-daqiiqo ah, oo lagu duubay 8K/24fps. Maya, waan kugu dhiiraday, isku day. Oo waa kan qabsashada: muuqaal 1-daqiiqo ah oo 8K ah oo ku socda 24fps wuxuu hayaa ku dhawaad ​​600 MB! Si aad u wareejiso fayl kan weyn, waxaad u baahan doontaa qorshe moobil oo aan xadidnayn ama xidhiidh Wi-Fi ah. Xataa haddii aad leedahay bandwidth ku filan, waxaa jira tiro yar oo apps ah kuwaas oo kuu oggolaanaya inaad ku wareejiso faylalka waaweyn hal mar. Marka la barbardhigo,

Cabbirka faylka ee fiidiyowyada 8K, xitaa 24fps, waa wax lagu qoslo

Hubaal, inta badan taleefannada casriga ah ayaa sii kordhin kara ama dib u cabbiri kara duubista si cabbirka faylka loo xakameeyo, laakiin markaa ama waxaad ku hadhaysaa muuqaal xallin hoose ama mid tayadiisu liidato oo ay ugu wacan tahay cadaadis^{(lossy compression)} lumay .

6. Dabacsanaanta toogashada

Waqti ka dib, duubista 8K waxay bilaabi kartaa inay bixiso dabacsanaan macquul ah ama xitaa waxay noqon kartaa meel kasta. Weli, sanadka 2022, xitaa marka la isticmaalayo mid ka mid ah taleefannada casriga ah ee ugu horumarsan meeraha, toogashada 8K waxay leedahay xaddidaadyo la taaban karo: hal kamarad oo keliya ayaa la heli karaa, soo-dhowayn yar, sawir-qaadid ka yar/xun, wax duubis ah oo HDR ah, qaab hoose, liiskuna wuu socdaa. . Dhanka kale, adigoo wax hoos u dhigaya ilaa 4K, waxaad heleysaa ku dhawaad ​​​​qaabka dhameystiran ee astaamaha laga heli karo barnaamijka kamarada^{(Camera )} : adoo isticmaalaya dhammaan shanta kamaradood (haa, kamarada hore ee Galaxy S22 Ultra caleemaha 4K sidoo kale) waxay ku siinaysaa balaadhan oo ah (optical!) Heerarka zoom, habaynta sawirku waa hab ka wanaagsan, waxaad aadi kartaa ilaa 60fps, iwm.

7. Dib u ciyaarista

Wanaagsan^(Great) , waxaad ku duubtay muuqaalkaaga 8K (7680 x 4320 pixels). Hadda waa maxay? Galaxy S22 Ultra wuxuu leeyahay shaashad aad u wanaagsan, oo leh xallinta 1440 x 3088 pixels iyo cufnaanta pixels oo siman oo wanaagsan (~ 500 ppi ). Laakiin taasi xitaa 4K maaha! Cufnaanta pixel-ka sare waa wax ka baxsan waxa bini'aadmigu garan karo (si dhab ah, qaado Galaxy S22 Ultra oo isku day inaad ku kala soocdo pixels gaarka ah isha qaawan - waxay u badan tahay inaad ku guul darreysato), xitaa haddii aad si uun u maamuli karto inaad isku dhejiso pixels badan oo isku mid ah. meel bannaan, farqiga u dhexeeya daawashada fiidiyoowga 4K iyo 8K ayaa noqon doona mid aad u yar.

Waxaad u baahan doontaa muraayad weynaysa...

Laakiin sidee ku saabsan daawashada waxa ku jira shaashad kale? Ma haysaa muqaal awood u leh inuu dib u ciyaaro 8K content? Haddii aad sameyso, waxaad tahay mid ka mid ah kuwa nasiib badan. Run ahaantii, dad aad u yar ayaa heli kara bandhigyada 8K. Intaa waxaa dheer, faa'iidooyinka daawashada fiidiyowga ee shaashadaha 4K (sidaa darteed, hoos u dhigista) waxaa hoos u dhigaya tayada hoose ee duubista marka loo eego 4K asalka ah ee Galaxy S22 Ultra uu duubi karo.

Waa maxay xalka ugu fiican ee lagu duubo taleefannada casriga ah?

Adiga oo wax walba ku xisaabtamaya, toogashada fiidiyowyada 8K ee casrigaaga miyay u qalantaa, mise aad bay u badan tahay? Aragtidayda, 2022, tignoolajiyada la heli karo hadda, uma qalmo. Xitaa uma qalmi doonto sanadka soo socda. Mise tii dabadeed. Xitaa haddii waxyaabo badan oo 8K ah la heli karo, kaliya waxaad si dhab ah u awoodi doontaa inaad ka faa'iidaysato xallintan shaashadaha 280 inji (7 mitir) xagga geesaha^{(on screens that are 280 inches (7 meters) in diagonal)} ah iyo heerar sare. Waxaan filayaa in duubista fiidiyooga ee 8K ay noqoto mid aad iyo aad u dabacsan marka la eego sifooyinka iyo tayada ay kor u kacdo, laakiin sidaas oo kale, kiisas adeegsigeeda ayaa noqon doona mid aad u xaddidan. Si aan u soo koobo, waa kuwan gunaanadkaygii ku saabsan ku duubista fiidiyowyada xallinta sare ee casrigaaga:

• Duubista 8K^{(8K recording)} waxay inta badan u jirtaa ujeeddooyin suuq-geyneed, maadaama ay had iyo jeer jiraan dib-u-dhacyo: ama tayada ayaa ka hooseysa tan duubista 4K, ma jirto xasilin muuqaal ah, qaab-dhismeedka ayaa hooseeya, ama sifooyin kale ayaa maqan. Waxa suurtogal ah in loo isticmaalo tafatir culus, si loo helo muuqaalo 4K ah oo aad loo dajiyay ama lagu dhimo 4K, laakiin xaqiiqdii maaha mid u qalma taleefannada casriga ah ee hadda (2022). Qaraarkan aad looguma talinayo duubista maalin-ka-maalin-ka-maalin ah wuxuuna u fiican yahay kiisaska isticmaalka gaarka ah.^{(This resolution is highly unrecommended for day-to-day recordings and is only good for specific use cases.)}
• Duubista 4K^{(4K recording)} waxay u muuqataa inay tahay meesha ugu macaan ee taleefannada casriga ah hadda, gaar ahaan Samsung Galaxy S22 Ultra , kaas oo ku toogtay fiidiyowyo muuqaal ah oo muuqaal ah 4K. Faylasha soo baxay ayaa ka yar kuwa loogu talagalay 8K, xallinta ayaa u oggolaanaysa wax badan oo tafatir ah oo loogu talagalay soosaarka 1080p, iyo taageerada dib-u-ciyaarista 4K ayaa noqonaysa mid aad u baahsan. Xalkani wuxuu ku fiican yahay helitaanka cajalado tayo sare leh.^{(This resolution is perfect for obtaining high-quality recordings.)}
• Duubista 1080p^{(1080p recording)} waa, ra'yigeyga (aan la jeclayn), sida ay uga bixi karto. Wali aad ayey ugu fiican tahay duubista fiidyaha ee maalin-maalin-ka-maalin ah iyadoo la isticmaalayo talefannada casriga ah ee dhex-dhexaadka ah ama calamadaha duugga ah, laakiin kuwa wax-abuuray, waxay noqonaysaa mid duug ah. Tusaale ahaan, ma hagaajin kartid qaabaynta xun ee soo saarista ka dib, iyo markaad toogto 1080p ee casriga ah sida caadiga ah waxay la socotaa qaar ka mid ah sifooyinka wanaagsan sida HDR 10+ duubista, 120fps (240fps si tartiib tartiib ah), iyo Fiidiyowga Sare^{(Super Steady Video)} ee Joogtada ah. laga heli karo Galaxy S22 Ultra , astaamahan waxay u badan tahay inay bilaabaan inay diyaar u noqdaan 4K sidoo kale, iyagoo 1080p dib ugu celinaya buugaagta taariikhda, sida HD ama 720p. 1080p waxay ku fiican tahay duubista maalinlaha ah, laakiin tayada muuqaalku maahan tan ugu fiican.^{(1080p is great for day-to-day recordings, but video quality is not the best.)}

Waa maxay ra'yigaaga? 1080p, 4K, ama 8K?

Waxaan jeclaan lahaa inaan ogaado ra'yigaaga ku saabsan go'aamada kala duwan ee duubista fiidiyowyada. Ma kula tahay in soosaarayaashu ay diiradda saaraan 8K, ama hagaajinta tayada sawirka 4K iyo 1080p? Ma kula tahay in aan ku dhegno 30fps, 60fps, ama aadno 120fps? I ogeysii faallooyinka

Smartphone video recording in 1080p, 4K, 8K: How much is too much?

Smartphone manυfacturers аre doing eνerything they can to brіng forward new and exciting featυres. Some аre more successful than others, some are only there fоr marketing purposes. While an increasing number оf flagship smartphones feature 8K video recording, is it really a useful аbility, or is it just a fad? In this article, I’m goіng to аnswer a few questionѕ that you may have regarding vіdeo reсordіng. Is 8K recording worth using? What’s the best resolution for video recording on smartphones? Equipped with thе аwesome Samsung Galaxy S22 Ultra, I analyzed different recording scenarios and I’m ready to present my findings:

The bigger, the better, right?

Before discussing video sizes and quality, let me first say this: for taking pictures, the larger the resolution, the better. If you can get similar raw (unprocessed) quality, higher resolution photos are better for the obvious reason that they contain more information. This means you can zoom in, reframe and downscale them to a lower resolution while preserving quality. For example, downsizing a 4K picture to 1080p will always yield a better result than shooting in 1080p. Now, moving on to videos…

TIP: If you’re confused by terms like 4K or 1080p, we recommend this article: What do the 720p, 1080p, 1440p, 2K, 4K resolutions mean?

1. Image quality and processing

Moving on to videos, the same point is generally true as well: for all intents and purposes, using a higher resolution for recording a video yields better quality for the finished product, all other things being equal. But that’s the thing: on smartphones, when recording videos, from a point on, other settings are not equal. Even when you’re shooting a video with all aids turned off (like AI, HDR, etc.), the smartphone does some heavy processing to make the videos better-looking. There is a sweet spot for this: if you go too low with the resolution, the video will look pixelated, but on the opposite end, using the maximum resolution that a sensor can capture will rob you of many processing features. This is true even on a flagship device like the Galaxy S22 Ultra: recording in 8K usually produces videos that look no better than those shot in 4K. In fact, some may argue that they look slightly worse, softer, and with more artifacts.

The sweet spot for the Samsung Galaxy S22 Ultra, from my perspective, is 4K video recording, since the quality of the recording is excellent, and downsizing it to 1080p will result in a better-quality video than one shot in 1080p:

In low light, the difference is even more visible. 8K videos are darker, with more noise, while 4K and 1080p videos can benefit from the full processing power of the chipset and the four cameras present on the back of the Samsung Galaxy S22 Ultra.

Of course, this is not necessarily the case with other flagship smartphones. Some produce better-quality videos when recording in 8K, but one of the main issues with this format starts to take shape: since 8K technology for smartphones hasn’t matured yet, the results can be hit or miss.

2. Stabilization

Since I mentioned automatic video processing, one of the most important methods that the Galaxy S22 Ultra uses to improve your video quality is a combination of optical image stabilization (OIS) and electronic image stabilization (EIS). In short, OIS works by physically moving the camera sensor in order to compensate for camera movements, while EIS uses clever algorithms and image cropping to achieve similar results. OIS is critical for photos, but for videos, EIS is much more important, in part because it reacts much faster. On some smartphones, like the Realme GT2 Pro, 8K videos are not stabilized, which obviously negatively affects recording quality. On other flagships, like the Samsung Galaxy S22 Ultra, the stabilization is excellent, and it works perfectly on all resolutions.

However, the Galaxy S22 Ultra has a feature called Super Steady Video (SSV) which is reserved for 1080p videos. You can activate it by going to the Video section of the Camera app and tapping on the hand icon in the upper part of the screen (assuming the smartphone is in portrait orientation).

Tap this icon to enable Super Steady Video on the Samsung Galaxy S22 Ultra

To provide this level of stabilization, the Galaxy S22 Ultra uses the ultrawide camera and a resolution of only 1080p, with a zoom range of 0.6 to 1.0. Since the ultrawide shoots natively in 4K and has a much larger field of view (120 degrees versus the 85 of the main camera, basically giving you that 0.6 zoom), restricting SSV to the ultrawide with a 1080p resolution and a limited zoom level gives the smartphone a lot of room to crop, reframe and adjust the image without losing quality.

The main takeaway from all this? To achieve the best stabilization, you need to have a lot of resolution overhead. Thus, shooting in 8K is not great if you need super steady images (at least, not with today’s smartphone technology).

3. Motion blur

Next, I disabled Super Steady Video (SSV) and shot two very shaky videos, with rapid hand movements, one at 1080p/30fps and one at 8K/24fps. In theory, both should take advantage of the standard OIS and EIS. Here’s the video I shot at 8K/24fps with the zoom at 1 (which is equivalent to 1.6 zoom on 4K and on 1080p). Please note that YouTube compresses the videos:

The video below was recorded at 1080p/30fps with a zoom of roughly 1.6 to match the zoom level used by the camera in 8K mode, and if you look closely, a fascinating thing pops up.

Okay, the standard image stabilization works well in both cases, nothing to comment there. But although static images clearly have a lot more detail (even viewed in 1080p), there is no discernible difference between the 8K and the 1080p recording when the image is moving. How can that be? The following picture compares a frame containing motion blur from each recording.

Still frame comparison (1080p vs 8K)

Motion blur quality stays roughly the same, and thus videos with lots of movement see no improvement in quality as long as the fps are similar (I’m oversimplifying things, as shutter speed and other factors have a big relevance here too). This means that, while 8K does bring benefits for taking pictures, when we’re talking about recording videos, the situation changes drastically. Quality improvements on videos with a lot of movement can only be achieved by increasing the framerate (a lot), in order to eliminate motion blur. But when motion blur disappears, the video looks unnatural.

4. Processing power, battery life, and heat

Recording 8K videos drains the battery much faster than, let’s say, shooting in 1080p. The reasons are obvious: more data captured means more data to be processed, much higher processor utilization, and more energy consumption. To prove my point: shooting a 5-minute video on 1080p/30fps took 2% off the battery while shooting a video in the same location, with the same settings, but with 8K/24fps, sucked 3%. It’s roughly 50% more, and that can make a difference if you’re recording longer or multiple videos. Not only that, but during the test, the Samsung Galaxy S22 Ultra even warned me against shooting in 8K for more than 5 minutes to avoid overheating. And indeed, at the end of the 5 minutes of recording in 8K, the device was unpleasantly hot. More heat means more battery degradation over time because heat is the enemy of batteries.

5. File size

This one is obvious, but I will mention it nonetheless: the higher the resolution, the larger the resulting file. It’s true for pictures, but it’s a real problem when it comes to videos. And not only because of the space available on the smartphone (although that is a problem as well since many smartphones don’t have expandable storage). No, it’s got more to do with file transfer. Just try to send a 1-minute video, recorded in 8K/24fps, to a friend. No, I dare you, try. And here’s the catch: a 1-minute 8K video at 24 fps occupies almost 600 MB! In order to transfer a file this large, you’ll need either an unlimited mobile plan or a Wi-Fi connection. Even if you have enough bandwidth, there are only a small number of apps that allow you to transfer such large files in one go. In comparison, a 1-minute 1080p video shot at 30fps takes up 124 MB of space, and a 4K video at 30 fps takes up 350 MB.

The file size for 8K videos, even at 24fps, is ridiculous

Sure, most smartphones can further compress or resize the recordings in order to keep file size under control, but then you are either left with a lower resolution video or with one that has poor quality due to lossy compression.

6. Shooting flexibility

With time, recording in 8K may start to offer reasonable flexibility or even become ubiquitous. Still, in 2022, even when using one of the most advanced smartphones on the planet, 8K shooting has significant limitations: only one camera available, less zoom, less/worse image processing, no HDR recording, low framerate, and the list goes on. Meanwhile, taking things down a notch to 4K, you get almost the complete set of features available in the Camera app: using all five cameras (yes, the front-facing camera on the Galaxy S22 Ultra shoots in 4K as well) gives you a wide range of (optical!) zoom levels, image processing is way better, you can go up to 60fps, etc.

7. Playback

Great, you recorded your video in 8K (7680 x 4320 pixels). Now what? The Galaxy S22 Ultra has an excellent screen, with a resolution of 1440 x 3088 pixels and an equally good pixel density (~500 ppi). But that’s not even 4K! The high pixel density is beyond what humans can perceive (seriously, take your Galaxy S22 Ultra and try to distinguish individual pixels with the naked eye - you will most likely fail), so even if you would somehow manage to cram more pixels in the same space, the difference between viewing a 4K video and an 8K video would be minimal.

You're going to need a magnifying glass...

But how about viewing the content on another screen? Do you have a display capable of playing back 8K content? If you do, you’re one of the lucky few. Realistically, very few people have access to 8K displays. Furthermore, the advantages of viewing the video on 4K screens (thus, downsizing) are offset by the lower quality of the recording compared to the native 4K that the Galaxy S22 Ultra can record.

What is the best resolution for recording with smartphones?

Taking all things into account, is shooting videos in 8K on your smartphone worth it, or is it too much? In my opinion, in 2022, with the technology available right now, it’s not worth it. It won’t even be worth it next year. Or the one after that. Even if more 8K content becomes available, you’d only be truly able to take advantage of this resolution on screens that are 280 inches (7 meters) in diagonal and at high framerates. I expect 8K video recording to become more and more flexible in terms of features and for its quality to increase, but even so, its use cases will be very limited. To sum up, here are my conclusions on recording high-resolution videos on your smartphone:

• 8K recording is mostly there for marketing purposes, as there are always drawbacks: either the quality is inferior to that of 4K recordings, there is no image stabilization, the framerate is low, or other features are missing. It could potentially be used for heavy editing, in order to obtain highly stabilized 4K videos or for downsizing to 4K, but definitely not worth it on current (2022) smartphones. This resolution is highly unrecommended for day-to-day recordings and is only good for specific use cases.
• 4K recording seems to be the sweet spot for flagship smartphones right now, especially for the Samsung Galaxy S22 Ultra, which shoots some great-looking videos in 4K. The resulting files are smaller than the ones for 8K, the resolution allows for plenty of editing for 1080p output, and support for 4K playback is becoming more and more widespread. This resolution is perfect for obtaining high-quality recordings.
• 1080p recording is, in my (unpopular) opinion, on its way out. It’s still excellent for day-to-day video recordings using mid-range smartphones or older flagships, but for content creators, it’s becoming outdated. For example, you can’t fix bad framing in post-production, and while shooting in 1080p on smartphones usually comes with some neat features like HDR 10+ recording, 120 fps (240 fps for slow-motion), and the Super Steady Video available on the Galaxy S22 Ultra, these features will most likely start to become available on 4K as well, relegating 1080p to the history books, just like HD or 720p. 1080p is great for day-to-day recordings, but video quality is not the best.

What is your opinion? 1080p, 4K, or 8K?

I’d love to know your opinion on the different resolutions for recording videos. Do you think manufacturers should focus on 8K, or on improving 4K and 1080p image quality? Do you think we should stick to 30 fps, 60 fps, or go to 120 fps? Let me know in the comments.
