Convert XviD to AVI — Free Online Converter

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.
