XviD files are already stored in AVI containers — making this conversion a re-encode within the same container format rather than a container change. XviD, the open-source MPEG-4 Part 2 codec created as a free alternative to DivX (its name is DivX reversed), was the dominant codec for scene releases and peer-to-peer video sharing during the early 2000s. The standard 700 MB CD-rip used XviD video with MP3 audio inside Microsoft's AVI (Audio Video Interleave) container.
Converting XviD-to-AVI re-encodes the MPEG-4 Part 2 video stream while keeping the same AVI container. This is useful for changing the video codec (e.g., to MJPEG for editing compatibility), adjusting bitrate or resolution, fixing corrupted XviD streams, or re-encoding with modern settings that older XviD profiles did not support.
Since XviD is already AVI, this conversion addresses situations where the AVI container is fine but the XviD codec stream needs modification. Some legacy video editing software reads AVI but does not decode MPEG-4 Part 2 — re-encoding to MJPEG or uncompressed AVI makes these files editable. Old XviD encodes with non-standard settings may cause playback glitches on certain hardware DVD players that nominally support XviD.
Re-encoding also serves as a repair mechanism. Corrupted XviD streams with broken B-frames or missing keyframes can be decoded and re-encoded into a clean AVI file. Additionally, XviD files encoded with early versions of the codec (pre-1.0) sometimes used non-standard packed bitstream modes that cause audio sync issues — re-encoding fixes these legacy artifacts.
FFmpeg reads the XviD AVI file using the mpeg4 decoder, producing raw video frames. These frames are then re-encoded using the selected codec — mpeg4 (MPEG-4 Part 2 with modern settings), mjpeg (for editing), or rawvideo (uncompressed) — and re-muxed into a new AVI container. Audio can be stream-copied (no re-encoding) if the MP3 track is fine, or re-encoded to PCM for editing workflows. The new AVI file has clean keyframe intervals and proper index chunks.
Re-encoding XviD to another lossy codec within AVI introduces a second generation of compression artifacts. If re-encoding to MPEG-4 Part 2, use a higher bitrate than the original (1500-2500 kbps vs the typical 800-1200 kbps scene release) to minimize visible quality loss. MJPEG or uncompressed AVI preserves the decoded quality perfectly but produces dramatically larger files — 2-10x the original size.

XviD to AVI conversion is a specialized re-encode operation that fixes legacy XviD codec issues, changes the video codec for editing compatibility, or repairs corrupted streams — all while maintaining the familiar AVI container format.
