Why convert MKV to XVID?
MKV (Matroska) is an EBML-based container that can already hold XviD-encoded video inside it. Files with the .xvid extension are AVI or MKV containers with Xvid (MPEG-4 ASP) video - not a distinct container format. XviD was an open-source MPEG-4 Part 2 codec popular in AVI files from 2001 to 2010 before being displaced by H.264.

- Re-encoding MKV video to XviD always involves quality loss; only do this if the target device genuinely cannot play H.264 in MP4.
- Hardware made after 2012 almost universally plays H.264 in MP4 - check your device before committing to a lossy XviD re-encode.
- If your MKV already contains XviD-encoded video, you can remux it to AVI without re-encoding, avoiding quality loss.
