Qhov chaw zoo tshaj plaws rau YouTube Uploads

Nkag siab txog YouTube’s Video Upload Requirements

YouTube txhawb ntau yam video tawm tswv yim, tab sis tsis yog txhua hom ntawv tsim muaj sib npaug thaum nws los txog rau upload zoo thiab ua kom ceev. Lub platform officially pom zoo cov ntaub ntawv MP4 nrog H.264 video codec thiab AAC suab codec rau kev pom zoo. Qhov kev sib xyaw no muab qhov sib npaug zoo tshaj plaws ntawm cov ntaub ntawv loj, zoo, thiab kev sib raug zoo thoob plaws txhua yam khoom siv thiab browsers. Thaum YouTube lees txais cov hom ntawv xws li MOV, AVI, WMV, FLV, thiab WebM, uploading hauv cov hom ntawv feem ntau ua rau lub sijhawm ua haujlwm ntev dua thiab muaj peev xwm degradation thaum YouTube txoj kev hloov dua siab tshiab. Lub platform cia li rov encodes tag nrho cov yeeb yaj duab uploaded rau ntau qhov kev daws teeb meem thiab cov qauv rau streaming, tab sis pib nrog cov hom ntawv pom zoo kom ua tau zoo tshaj plaws. Kev nkag siab txog cov kev cai no yog qhov tseem ceeb rau cov neeg tsim cov ntsiab lus uas xav kom lawv cov yeeb yaj kiab saib kev tshaj lij thiab thauj khoom sai rau cov neeg saib.

• MP4 nrog H.264 codec yog YouTube nyiam hom ntawv
• Cov ntaub ntawv loj tshaj plaws txwv yog 256GB lossis 12 teev ntev
• Txhawb nqa tus nqi suav nrog 24, 25, 30, 48, 50, thiab 60 FPS

Optimal Video Resolution thiab Bitrate nqis

Video daws teeb meem thiab bitrate ua hauj lwm tes-nyob rau hauv-tes los txiav txim koj upload qhov pom kev zoo thiab cov ntaub ntawv loj. Rau 1080p uploads, YouTube pom zoo ib tug bitrate ntawm 8-12 Mbps rau tus qauv ncej tus nqi thiab 12-18 Mbps rau siab ncej cov ntsiab lus (50/60fps). Cov bitrates siab dua khaws cov ntsiab lus ntau dua thiab txo cov khoom siv compression, tab sis lawv kuj ua rau cov ntaub ntawv loj dua thiab ntev dua lub sijhawm upload. Thaum xaiv qhov kev daws teeb meem, xav txog koj cov khoom siv thiab cov neeg tuaj saib. Thaum 4K (2160p) muab qhov meej meej zoo nkauj, nws yuav tsum muaj cov bitrates siab dua (35-45 Mbps) thiab sijhawm ua haujlwm ntev dua. Ntau tus tsim pom tias 1080p muab qhov chaw qab zib ntawm qhov ua tau zoo thiab kev ua tau zoo. Nws tseem yog ib qho tseem ceeb kom phim koj qhov kev daws teeb meem upload rau koj cov kev daws teeb meem sau cia – qhov kev daws teeb meem qis dua cov duab tsis tshua muaj kev txhim kho zoo thiab feem ntau qhia txog cov khoom cuav uas tsis xav tau. Txhawm rau kom tau txais txiaj ntsig zoo, siv qhov sib txawv bitrate (VBR) encoding es tsis tas li bitrate (CBR). VBR faib cov khoom ntau ntxiv rau cov xwm txheej nyuaj nrog ntau cov lus tsa suab lossis nthuav dav thaum siv cov khoom tsawg dua rau cov xwm txheej yooj yim, ua rau muaj txiaj ntsig zoo ntawm cov ntaub ntawv me me.

Audio Configuration rau Professional Results

Lub suab zoo feem ntau tsis saib xyuas tab sis ua lub luag haujlwm tseem ceeb hauv kev saib xyuas thiab khaws cia. YouTube pom zoo AAC suab codec nrog tus nqi piv txwv ntawm 48kHz thiab bitrate ntawm 384 kbps rau lub tso suab suab. Cov kev teeb tsa no muab cov suab paj nruag-tshwj xeeb tshaj tawm thaum tuav cov ntaub ntawv tsim nyog. Tsis txhob siv cov nqi qis dua li 128 kbps, vim tias lawv tuaj yeem ua kom pom cov duab zoo nkauj uas cuam tshuam los ntawm kev pom. Rau cov neeg tsim cov ntsiab lus siv ntau lub suab, xws li cov suab paj nruag thiab cov suab kaw, nws yog ib qho tseem ceeb kom sib npaug qib ua ntej upload. YouTube lub suab ua qee zaum tuaj yeem ua kom muaj qhov tsis txaus ntseeg uas twb muaj lawm, ua rau kev sib xyaw tsis zoo txawm tias pom ntau dua. Xyuas kom koj lub suab nce siab nyob ib puag ncig -6dB rau -3dB, tawm hauv lub taub hau rau YouTube kev ua haujlwm thaum tsis txhob cuam tshuam. Cov qib suab zoo ib yam thoob plaws hauv koj cov vis dis aus kuj tseem txhim kho cov kev paub dhau los ntawm cov neeg saib thiab txo qis qhov tshwm sim ntawm cov neeg saib kho lawv cov ntim tas li.

Frame Rate thiab Motion Settings

Ncej tus nqi cuam tshuam rau ob qho tib si saib kev paub thiab cov ntaub ntawv loj ntawm koj YouTube uploads. Cov ntsiab lus txheem feem ntau siv 24fps (cinematic), 25fps (PAL cheeb tsam), lossis 30fps (tus qauv tshaj tawm), thaum kev ua si thiab cov ntsiab lus siab feem ntau tau txais txiaj ntsig los ntawm 60fps rau kev ua si zoo dua. Lub hauv paus ntsiab lus tseem ceeb yog kom phim koj tus ncej tus nqi xa mus rau koj cov khoom siv – zam kev hloov pauv tus nqi thaum ua tau raws li nws tuaj yeem ua kom paub txog kev hais lus tsis txaus siab lossis kev ua kom pom tseeb. Rau cov ntsiab lus siab ncej, xyuas kom koj tus bitrate siab txaus los tswj cov ntaub ntawv ntawm lub cev muaj zog. Ib 60fps video yuav tsum tau kwv yees li 1.5x tus bitrate ntawm sib npaug 30fps cov ntsiab lus los tswj cov qib zoo tib yam. Tsis tas li ntawd, xav txog koj cov neeg tuaj saib cov cwj pwm thiab cov khoom siv. Thaum 60fps muab cov lus tsa suab zoo dua, nws xav tau ntau dua bandwidth thiab ua lub zog, uas tej zaum yuav tsis zoo rau cov neeg saib ntawm kev sib txuas qeeb lossis cov khoom qub. Thaum encoding cov lus tsa suab-hnyav zoo li cov yeeb yaj kiab gaming lossis cov duab ua kis las, siv qhov kev kwv yees tsim nyog hauv koj lub encoder. Qhov zoo tshaj qhov kev kwv yees algorithms tuaj yeem txhim kho qhov pom ntawm cov khoom txav nrawm thiab txo cov khoom cuav, txawm tias lawv nce sijhawm encoding.

Xim Space thiab Dynamic Range Considerations

Xim qhov chaw thiab ntau qhov chaw teeb tsa muaj feem cuam tshuam li cas koj cov yeeb yaj kiab tshwm nyob rau hauv cov khoom siv sib txawv thiab cov duab. YouTube txhawb nqa ob tus qauv dynamic ntau yam (SDR) thiab siab dynamic ntau yam (HDR) cov ntsiab lus, tab sis feem ntau ntawm cov neeg saib tseem saib ntawm SDR cov lus. Rau cov ntsiab lus SDR, siv Rec. 709 xim qhov chaw (tseem hu ua sRGB) nrog ntau yam tsawg (16-235) rau kev tshaj tawm-kev nyab xeeb xim uas tso saib tsis tu ncua thoob plaws txhua yam khoom siv. HDR cov ntsiab lus muaj nthuav dav xim gamut thiab brightness ntau yam tab sis yuav tsum tau tshwj xeeb encoding tsis thiab pom zoo li. Yog tias koj uploading HDR cov ntsiab lus, siv Rec. 2020 xim qhov chaw nrog PQ (Perceptual Quantizer) lossis HLG (Hybrid Log-Gamma) hloov ua haujlwm. Txawm li cas los xij, xyuas kom meej tias koj cov ntsiab lus tau raug ntes lossis tsim hauv HDR – tsuas yog chij SDR cov ntsiab lus raws li HDR yuav ua rau cov xim ntxuav thiab tsis pom kev. Rau qhov tseeb xim, ib txwm ua haujlwm hauv ib puag ncig calibrated thiab xa tawm siv tib qhov chaw xim raws li koj qhov project. Zam tsis siv neeg xim qhov chaw hloov dua siab tshiab, vim nws tuaj yeem hloov xim tsis tau xav txog. Yog tias koj tsis paub meej txog kev teeb tsa xim, lo nrog Rec. 709 / sRGB, uas ua kom muaj kev ua si zoo ib yam thoob plaws ntau yam khoom siv thiab saib cov xwm txheej.

Kev Npaj Cov Ntaub Ntawv thiab Upload Optimization

Kev npaj cov ntaub ntawv kom raug tuaj yeem txo lub sijhawm upload thiab ua haujlwm qeeb. Ua ntej uploading, xyuas kom meej tias koj cov ntaub ntawv video yog formatted thiab optimized. Siv cov kev soj ntsuam zoo dua li cov yees duab sib cuam tshuam, vim tias cov ntsiab lus interlaced tuaj yeem ua rau cov khoom siv sib txuas ntawm cov khoom siv niaj hnub no. Tsis tas li ntawd, tso lub moov atom thaum pib ntawm MP4 cov ntaub ntawv (tseem hu ua ‘web optimization’ lossis ‘fast start’) kom muaj kev vam meej rub tawm thiab pib ua si sai dua. Xav txog koj qhov kev sib txuas hauv internet thiab upload sijhawm thaum npaj cov ntaub ntawv. Cov ntaub ntawv 4K loj tuaj yeem siv sijhawm ntau teev los rub tawm ntawm kev sib txuas qeeb, thiab YouTube cov kab ua haujlwm tuaj yeem ntxiv qeeb ntxiv thaum lub sijhawm ncov. Rau lub sij hawm-sensitive cov ntsiab lus, uploading lub sij hawm off-peak teev (feem ntau tsaus ntuj los yog sawv ntxov ntxov nyob rau hauv koj cheeb tsam) feem ntau ua rau ua hauj lwm sai. Koj tseem tuaj yeem xa cov yeeb yaj kiab uas tsis muaj npe lossis ntiag tug ua ntej kom ua tiav ua ntej ua rau pej xeem. Cov ntaub ntawv naming thiab metadata lub koom haum yog feem ntau overlooked tab sis qhov tseem ceeb ntawm cov txheej txheem upload. Siv cov npe piav qhia thiab xyuas kom koj cov video editor xa tawm cov metadata huv. Qee qhov kev kho software suav nrog cov metadata uas tsis tsim nyog uas tuaj yeem ua rau cov ntaub ntawv ntau thiab tsawg lossis ua rau muaj teeb meem ua haujlwm. Muaj koj tus duab me me, lub npe, cov lus piav qhia, thiab cov cim npe npaj ua ntej upload kuj tseem ua rau cov txheej txheem tshaj tawm.
