What is AVI index?

Audio Video Interleave or AVI is a popular video format developed for Windows to store large-sized videos. A video file data is usually divided into blocks or chunks that contain file header, metadata, codecs, and other audio/visual data information. In AVI format, there’s an additional sub-chunk called ‘idx1,’ which indexes these data chunks. This is known as the file index. It is an important part of AVI file structure that is required to efficiently play audio and video in sync. If a media player doesn’t find this sub-chunk or index, it won’t be able to play AVI video correctly.

What causes AVI file index corruption?

The file index in AVI videos can get damaged or broken due to virus infection, bad sectors in the drive, or improper file transfer/ processing. An unsecure program used to edit, convert, or open AVI video can also damage file index.
