Craig,
Basically I see two types of corrupt files:
1. Application crashed/hangs/runs out of disk space, before movie can be closed. As a result, the movie index (header, tail) is not written, and the file refuses to open.
2. Recording ended correctly, but movie doesn’t have video.
The cases below come from my repair customers, who do not usually indicate the versions they are using.
All are Mac users.
case [09039], January 2009
MacPro running current OS and latest quicktime

The file was corrupted by the HDD running out of space unexpectedly, and then the capture froze.
Media: DV PAL and AAC audio.
Repair Technique: Reindexing

case [09111], March 2009
Quicktime H264 1500kbps 480X360 25FPS
After recording the QT file video track was black. File opens w/ QuickTime, audio is here, but no video.
Repair Technique: Inspection of structure shows that all is in place except video stsd (sample description). We add this atom and file is OK.

Wirecast crasched twice and 2 recorded files where damaged, the other one is 113 mb.
