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 bụ nke a na-eme n'ihi na ọ dị n'ime: VP8 ma ọ bụ VP9 vidiyo (AV1 nke ọfụụ) na Vorbis ma ọ bụ Opus ụda, nakwa ihe ọbụla ọzọ.

Vidéọ̀kọ́ètì ole ka ọ̀fụ̀ụ AV1 na-eji?

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 bụ video codec royalty-free nke Alliance for Open Media wepụtara na 2018 dị ka onye na-eso ụzọ VP9.
Ọ ga-adị ndụ n'ịgbanwe WebM ka 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.
M ga-echekwa fréèmù ọfụụ mgbe m na-ebugharị WebM ka AV1?
