FaʻAvasega AV1 i MP4

E suia e le codec le mea e faʻamoemoeina mai i le faila output. O se itu o lenei toe faʻavasegaina e taʻua o se encoding nai lo se wrapper, o lea o le a toe foʻi mai o le bitstream i totonu o le pusa e sili ona lelei - e masani ai MP4 poʻo MKV. O le faʻalautelega e faʻaalia ai le pusa; o le codec o le mea moni na filifili ai le tele o le faila ma le mea e taʻalo ai.

E faalagolago i le MP4 container. MP4, MOV ma MKV output faaaogaina H.264, lea e taalo i le tele o telefoni, browser ma TV. WebM output faaaogaina VP9. AVI, WMV ma MPEG output faaaogaina le codecs sili atu i latou formats na fuafuaina mo. MP4 o le ISO / IEC 14496-14, faʻatapulaʻaina i le 2001 ma na mafua mai i le tutusa QuickTime box layout MOV faʻaaogaina.

Yes, the main audio track comes through, re-encoded to a codec the MP4 container plays, for example AAC in MP4 and MOV or Opus in WebM. Most conversions keep only that one track (the one with the most channels), so alternate languages and commentary are dropped. MP4 to MOV, and AVI, WMV, MPEG, FLV or VOB to MKV with the default settings, keep every audio track.

O le a teu le fua o le ata pe ae suia: o se 24 fps AV1 e tumau pea i le 24 fps i le MP4. O le faʻatulagaina o le fua o le ata e mafai foi ona toe faʻaigoaina i le 60, 30 poʻo le 24 fps. E suia e le fua o le ata; e le faʻaeseeseina le vitio pe aveese le 3:2 pulldown.

It depends on what happens to the video. MKV to MP4 or MOV with the default settings copies the video stream unchanged, so the size stays close to the source. Most other pairs re-encode it: a high-bitrate AV1 usually comes out smaller, while an already heavily compressed one can grow. Smaller File under Quality gives the smallest output, and H.265 in the Codec setting (MP4, MOV and MKV) is usually smaller than H.264 at similar quality but plays on fewer devices.

MP4 ma H.264 taalo i luga o le tele o telefoni, browser ma TV. MOV ma H.264 taalo i luga o masini Apple ma le tele o TV ae le i luga o so o se telefoni Android e sili atu. MKV manaomia se app pei o VLC i le iOS, ma WebM o le fale i browsers. E leai se masini preset i lenei itulau, o lea filifili le format target e lagolagoina e lau masini. O le MP4 o le mea sili ona saogalemu e mafai ona ofoina atu - o soʻo se telefoni, browser, console, editor ma Smart TV na fausia i le seneturi talu ai e taʻalo ai e aunoa ma se polokalama faʻaopoopo. E lagolagoina e le MP4 se tasi lava le fuataga o le subtitle e lauiloa tele (mov_text), ma e le mafai ona faʻatuatuaina le leo e tele-faigafaga i fafo atu o le desktop players.

There is no fixed time: it depends on the length, the resolution and the target format. Conversions run on our servers' CPUs with software encoders; there is no GPU acceleration. MKV to MP4 or MOV with the default settings copies the video stream and is the quickest. A re-encode to H.264 takes longer, and WebM (VP9) is the slowest target, several times slower than H.264 in our tests.

The converter has no resolution cap of its own; the limit is the upload size allowed on your plan, and the resolution stays as it is unless you choose 1080p, 720p or 480p. There is no HDR processing or tone mapping. When the video stream is copied (MKV to MP4 or MOV with the default settings), HDR10 passes through untouched. A re-encode drops the HDR10 mastering metadata, and with a Quality, Resolution or Frame Rate setting some pairs also reduce the video to 8-bit colour, so an HDR AV1 can look washed out.

Yes. Uploaded AV1 files are processed on our own conversion servers, no person reviews them, and they are never shared. The upload and the converted MP4 are both deleted automatically about 24 hours after the conversion, which leaves time to download the result. See /privacy/ for the full policy.

Not in the same step. Use /trim-video/ or /video-cutter/ to clip the AV1 first, or /rotate-video/ to turn it, then run the AV1 to MP4 conversion. Trimming first is faster than re-encoding the whole AV1 just to drop unused footage.

I le tele o taimi, ua fa'aosoina le output e sili atu nai lo le fa'avae. Ta'u le fa'aiuga o le fa'aiuga, filifili le Maualuga le Maualuga i lalo o le Maualuga, teu le Resolusi i le Fa'avae ma toe fa'aosoina. E leai se CRF po'o se itu o le bitrate i lenei itulau; o le Maualuga le Maualuga o le fa'atonu e teuina ai le tele o fa'amatalaga. AV1 tuuina atu e tusa ma le 30% sili atu le faʻaosoina nai lo H.264 i le tutusa lelei ma e le o faia se totogifuapauina laisene, o lea la YouTube ma Netflix push ia.
