The most important fix in this version is a change to the code that reads AVI hierarchical indices. Normally these indices are only two levels deep, with a master index in the header and sub index blocks covering no more than 4GB. If you're wondering whether deeper indices are possible, the answer is an emphatic yes. It turns out there's at least one hardware/software editing solution that produces AVI files with deep index trees, because it links all of the subindex blocks with internal nodes arranged in a degenerate tree. VirtualDub is a video capture/processing utility, licensed under the GNU General Public License (GPL). It lacks the editing power of a general-purpose editor such as Adobe Premiere, but is streamlined for fast linear operations over video. It has batch-processing capabilities for processing large numbers of files and can be extended with third-party video filters. VirtualDub is mainly geared toward processing AVI files, although it can read (not write) MPEG-1 and also handle sets of BMP images.
