Kodi ndingatani kuti ndibwezeretse AVI ku MPEG popanda kuwononga mtundu wa kanema?

Ikani fayilo yanu ya AVI ndipo wosintha amayendetsa CRF-based re-encode yoyang'anira kutulutsa kwa MPEG (CRF 18 mosalekeza, matanthauzo ochepa = fayilo yayikulu / yapamwamba). Codec imasankhidwa kuti igwirizane ndi MPEG - H.264 kwa MP4 yokhala ndi kutalika, H.265 kwa MKV yokhala ndi kukula, VP9 kwa WebM, AV1 kwa ma pipelines atsopano.

Kodi ndi codec iti ya video yomwe MPEG imagwiritsa ntchito?

Izi zimadalira bokosi la MPEG. MP4 imasinthidwa ku H.264 kuti ithandizire kusewera kwa mafoni, mawebusayiti ndi Smart TV.

Ngati codecs amasiyana, audio imasinthidwa kukhala AAC / Opus / Vorbis malinga ndi zomwe MPEG zimathandizira. Audio yokhala ndi ma track ambiri (mawu owonjezera, mabungwe) amasungidwa.

Kodi kukula kwa fayilo isintha bwanji kuchokera ku AVI kupita ku MPEG?

Same-codec re-mux (AVI H.264 → MPEG H.264 just changing container): nearly identical size. Codec change can swing dramatically: H.264 → H.265 typically halves the file at the same visual quality; VP9 is roughly comparable; AV1 cuts another 20-30% but is slower to encode.

Kodi fayilo ya MPEG idzasewera pa iPhone, Android ndi Smart TVs?

MP4 / H.264 imasewera mwachilengedwe pazinthu zonse zamakono. MOV / H.264 imasewera pazinthu za Apple ndi ma TV ambiri koma si nthawi zonse pa Android yakale. MKV iyenera VLC pa iOS. WebM ndi browser-first. Zosankha zopitilira muyeso zimaphatikizapo "kugwirizana kwa chipangizo" choyamba chomwe chimasankha chotetezeka MPEG codec / chidebe chazolinga zanu.

Kusinthanso kwa codec yomweyo ndi nthawi ya 30 mpaka 60 kwa fayilo ya 1-hour. Kodi yokhala ndi codec yokhala ndi codec imagwira ntchito panthawi ya 0.3-0.7x yokhala ndi GPU, kotero 1-hour AVI → MPEG imatha m'maola 18-40 malinga ndi resolution ndi codec yofunikira.
