Video lenght vs 4gb size limit

[Ofnietdan]

Hello,

So I have a webcam recording of 1:30h. But only 10 minutes is recorded on file.
Guess the program has overwritten previous content, since the size limit is 4gb on windows.
No new avi files were made... But windows explorer still says that there is still 1:30h in there.
Any ways to fix this? Or is windows just wrong and 1:20 of my video is lost?

Thanks folks

There isn't a 4GB limit in Windows, it's the avi file writer which likely has this limitation. We have the OpenDML format which allows for avi files larger than 4GB but your application may not have that (although in that case it should be smart enough to split the files up but I guess they forgot about that too).

You can try opening the file in VirtualDub[1] and see if it shows anything different. If that does actually show the full length you may be able to simply remux it without encoding anything to fix the avi container.

The 4 GB file size limit is inherent to FAT32 File System with the default 4 KB Cluster Size. Since you didn't said any more useful info, I don't know if you're hitting FAT32 limit or not (Which is common if you're using an USB Flash Drive, as many people use it).
