Upload your MP4 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 WebM output gets a codec its container supports: H.264 for MP4, MOV and MKV, VP9 for WebM. N'ebe ọ bụla MP4 n'oké ọhịa bụ H.264 vidiyo na AAC audio; container na-echekwa HEVC, AV1 na VP9. 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, na ọbụla ọzọ.

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. WebM bụ subset nke Matroska nke Google bipụtara na 2010 iji nye HTML5 vidiyo na-enweghị ikike ikike.
Ọ ga-adị ndụ n'ịgbanwe ụda m site na MP4 gaa na WebM?
+
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.

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