Upload your WebM file and set Quality to High Quality in the conversion options. That re-encodes the video at the highest quality setting (CRF 18 for H.264 and VP9 output), which keeps the most detail at the cost of a larger file. The default, Balanced, uses the standard setting. The AV1 output gets a codec its container supports: H.264 for MP4, MOV and MKV, VP9 for WebM. WebM an yi shi da nufin ya zama mai ƙunci: VP8 ko VP9 bidiyo (AV1 da aka fi amfani da shi a baya) tare da Vorbis ko Opus sauti, da kuma komai na daban.

Wanne codec na bidiyo ne fitarwa AV1 take amfani dashi?

It depends on the AV1 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. AV1 shi ne free-da-rai video codec da Alliance for Open Media ya fitar a cikin 2018 kamar yadda mai zuwa ga VP9.
Shin za'a iya canza waƙoƙina na sauti daga WebM zuwa AV1?
+
Yes, the main audio track comes through, re-encoded to a codec the AV1 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.

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.
Mene ne mafi girman ma'aunin rarraba da ake goyon baya ga WebM zuwa AV1?
+
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 color, so a HDR WebM can look washed out.
Shin WebM bidiyo na na sirri ne yayin canjawa zuwa AV1?
+
Yes. Uploaded WebM files are processed on our own conversion servers, no person reviews them, and they are never shared. The upload and the converted AV1 are both deleted automatically about 24 hours after the conversion, which leaves time to download the result. See /privacy/ for the full policy.
