Read time 5 minutes

Summary: AVI, a Microsoft video format from 1992, is used for audio and video. VLC Player sometimes encounters AVI indexing issues. You can manually fix this in VLC Player or use professional software for faster repair. AVI format has limitations, including codec compatibility and file size.

AVI stands as one of Microsoft’s pioneering video formats, originating in 1992 during the early days of CD and DVD technology. Originally conceived to facilitate the playback of video and audio content on DVD players, AVI has since established itself as a reliable container for streaming both audio and video data. Notably, the U.S. Government has adopted AVI as the official format for preserving digital video content.

Why does the AVI index file get stuck in VLC Player?

AVI format divides the video file data into several blocks or chunks. Each chunk has a FourCC tag for easy identification. AVI file separates each chunk into multiple sub-chunks. The first sub-chunk is the header of that limited part that saves the metadata of the video.

The metadata will be about the video, its width, its height, and frame rate. The second chunk will save the actual video and audio parts.

The third sub-chunk is the optional one with the ‘idx1’ tag that indexes the offsets of file data.

All these sub-chunks work collectively and run the AVI file.

Sometimes, the VLC Media player shows the error that the idx1 index is not present in the sub-chunk. It is required to move between the timestamp of videos properly.
