Ingabe umsindo wami uzophila ngokuguqulwa MP4 kuya ku FLV?

Yebo, umsindo omkhulu ohambayo udlula, uphinde ukhodwe ku-codec i-FLV idlala, isibonelo, i-AAC ku-MP4 ne-MOV noma i-Opus ku-WebM.

MKV kuya MP4 noma MOV ngezinhlelo ezijwayelekile zikopisha umsinga wevidiyo futhi zishesha. Ukuphinda-ukuguqula ku-H.264 kuthatha isikhathi eside, futhi WebM (VP9) yinjongo ehamba kancane, izikhathi eziningi ezihamba kancane kune-H.264 ezivivinyweni zethu.

Akukho HDR ukucubungula noma ukudweba kwethoni. Uma ividiyo ikhophiwe (MKV kuya ku-MP4 noma MOV ngezinhlelo ezijwayelekile), i-HDR10 idlula ngaphandle kokuchofoza. Ukuphinde ubhale kabusha i-HDR10 mastering metadata, futhi ngekhwalithi, ubukhulu noma i-frame rate setting ezinye izibini zikhuphula i-video ibe ngombala we-8-bit, ngakho-ke i-HDR MP4 ingabonakalisa i-washed out.

Ingabe i-MP4 yami yevidiyo imfihlo ngesikhathi sokushintsha?
