Upload your WMV 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 VOB output gets a codec its container supports: H.264 for MP4, MOV and MKV, VP9 for WebM. WMV na-eburu Microsoft onwe VC-1 ma ọ bụ WMV3 video na WMA ụda - codecs na-erughị ihe ọ bụla n'èzí Windows decodes natively.

It depends on the VOB 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.

Ọ ga-adị ndụ n'ịgbanwe ụda m site na WMV gaa na VOB?
+
Yes, the main audio track comes through, re-encoded to a codec the VOB 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.
