Upload your AVI 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 MP4 output gets a codec its container supports: H.264 for MP4, MOV and MKV, VP9 for WebM. AVI faịlụ ndị ahụ na-echere codecs ndị ọfụụ: na-atụ anya MPEG-4 Part 2 (DivX/Xvid), Motion JPEG mọọbụ frame ndị a na-ewepụtụla n'ime n'ime n'ihi na H.264.

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 bụ ISO/IEC 14496-14, standardized na 2001 na-abịa site na otu QuickTime igbe ịdị MOV na-eji.
Ọ ga-adị ndụ n'ịgbanwe ụda m site na AVI gaa na MP4?
+
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.
