Digidesign Pro Tools AVOption patch

Digidesign Pro Tools AVOption patch is a patch used to fix a problem encountered by AVOption users for capturing video on systems running Mac OS9. Thesymptom is that during video capture, capture is unexpectedly aborted by PT usually returning an error like "an OS error type-39 occured" and/or a "critical video engine error". The problem is caused when trying to capture files larger than 2Gb underMac OS9. Typically this abort will occur somewhere around 7 minutes into a capture with an AVR 77 level selected. Theproblem is NOT related to the AVR level but rather to the fact that OS9 is preventing Pro Tools from creating multiple clip files.To use the patch, exit out of Pro Tools. Then copy the old ABVB.dll file to a safe location. The ABVB.dll file is located in theVideo Engine folder which is located in the DAE folder which is located in the System folder. After moving the old ABVB.dll fileto a new location, download the updated ABVB.dll file from the Digidesign website(2MB.hqx file, includes the.dll file and thisReadMe) and put it in the Video Engine folder where the old ABVB.dll was located. No restart is necessary.
