About Video Converter
Video Converter changes container and codec — MP4, WebM, MOV, MKV — so a file plays on the device or platform that rejected the original.
H.264 in MP4 is the compatibility choice; VP9/WebM is smaller for the web but not accepted by some older editors.

Conversion re-encodes, so quality and file size both change.
Questions about Video Converter
Which format is most compatible?
MP4 with H.264 and AAC audio plays essentially everywhere.
Does converting reduce quality?
Yes, unless the streams are copied. Re-encoding always loses a little.
Can I keep the same quality?
Raise the bitrate, but expect a larger file; there is no free lunch.
Why does it take so long?
Video encoding is CPU-bound. Length and resolution dominate the time.
