Description

See these threads:
- [Not able to open full length of large AVI file.](http://imagej.1557.x6.nabble.com/Not-able-to-open-full-length-of-large-AVI-file-tt4496180.html)
- [AVI re-opening problem](http://imagej.1557.x6.nabble.com/AVI-re-opening-problem-tt5014442.html)

According to Michael Schmid, the issue is that the `AVI_Writer` plugin only writes AVI 1.0, not 2.0, which does not support files larger than 2GB.

According to Frank Shaffer, one workaround is to run through the bogus AVI files through VirtualDub first before using them elsewhere.

Research direction

Start by locating the AVI_Writer plugin and reviewing how it writes AVI 1.0 files, then read the linked discussions for the large-file failure details. Done means large AVI files no longer become malformed or unusable when they exceed 2GB, with validation against the reported reopening and length problems.
