Mabadiliko AV1 kwa MP4

Sehemu moja ya wongofu huu inaorodhesha ukwazo wa karatasi hiyo badala ya kanga, kwa hiyo kile kinachorudi ni kile kisehemu kidogo cha gesi ambacho ndani yacho hukifaa zaidi toka kwa kawaida MP4 au MKV. mpanuo huo unarudisha chombo hicho; msimbo huo ndio hasa umeamua ukubwa na mahali kinapocheza.

It depends on the MP4 container. MP4, MOV and MKV output use H.264, which plays on practically every phone, browser and TV. WebM output uses VP9. AVI, WMV and MPEG output use the older codecs those formats were designed for. MP4 ni IO/IEC 14496-14, ambayo imewekewa kiwango cha mwaka 2001 na kutolewa kwenye mpangilio uleule wa haraka wa wakati (MV) ambao unatumia.

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, VOB or M4V to MKV, keep every audio track.

Yes. The frame rate is kept unless you change it: a 24 fps AV1 stays 24 fps in the MP4. The Frame Rate setting can also convert to 60, 30 or 24 fps. It changes the rate only; it does not deinterlace the video or remove 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 with H.264 plays on practically every phone, browser and TV. MOV with H.264 plays on Apple devices and most TVs but not on every older Android phone. MKV needs an app such as VLC on iOS, and WebM is at home in browsers. There is no device preset on this page, so choose the target format your device supports. MP4 ndio shabaha salama zaidi ya usafirishaji wa kila simu, kipitisha - habari, kifariji, mhariri na TV yenye Smart iliyojengwa katika mwongo uliopita ikiicheza bila kutumia programu za ziada. MP4 hutegemeza tu mtindo mmoja wa maneno yaliyo na mizizi mingi (mov_ext), na sauti za viraka vingi hazitegemeki katika nafasi ya wachezaji wa meza.

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.

Weka Urekebishaji wa Mambo ya Asili na ugeuze tena. Hakuna uwanja wa CRF au wa kupandisha mdogo katika ukurasa huu; Mambo Makuu ni mazingira yanayoweka habari zaidi. AV1 husambaza takriban asilimia 30 ya kitambaa cha kufinya kuliko H.264 kwa kiwango kilekile na hailipizi ada ya leseni, ndiyo sababu YouTube na Netflix hukisukuma.
