Tiontaigh AV1 chun WebM

Athraíonn sé cad a bheith ag súil leis ón aschur comhad. Taobh amháin den chomhshó ainmníonn ionchódú seachas wrap, mar sin cad a thagann ar ais go bhfuil an bitstream taobh istigh cibé coimeádán oireann sé is fearr — MP4 nó MKV de ghnáth. Léiríonn an síneadh an coimeádán; is é an codec cad a chinn i ndáiríre an méid comhaid agus áit a mbeidh sé a imirt.

It depends on the WebM 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. Is WebM foshraith dian de Matroska a d'fhoilsigh Google i 2010 go sonrach a thabhairt HTML5 físeán coimeádán saor ó ríchíosanna.

Yes, the main audio track comes through, re-encoded to a codec the WebM 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 WebM. 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. Imríonn WebM go dúchasach i ngach brabhsálaí nua-aimseartha gan aon bhreiseán, gan aon táille ceadúnais agus gan nochtadh paitinne, rud a fhágann gurb é an réamhshocrú é d'fhíseán leabaithe gréasáin. Is WebM oiriúnach bocht in áit ar bith lasmuigh de bhrabhsálaí - eagarthóirí físe, gailearaithe dúchais fón agus Smart TVs neamhaird den chuid is mó é.

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 WebM 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 WebM conversion. Trimming first is faster than re-encoding the whole AV1 just to drop unused footage.

Usually the output was compressed harder than the source. Open the conversion options, choose High Quality under Quality, keep Resolution at Original and convert again. There is no CRF or bitrate field on this page; High Quality is the setting that keeps the most detail. AV1 sheachadann thart ar 30% comhbhrú níos fearr ná H.264 ag an caighdeán céanna agus déanann aon táillí ceadúnais, agus sin an fáth YouTube agus Netflix bhrú air.
