I recorded about 5 hours of gameplay (Cities Skylines) without any problems. However, the last file (24.5 GB, .avi, about 1.5h) can't be played with any kind of media player or video editing software. I tried Windows media Player, VLC, Potplayer, Movie Maker and Magix Video deluxe 2015. The screen stays black but audio is okay.
That's a big problem for me, because these last 1.5h are very important for my project. Is there a way to fix the file? (I tried Bandifix, but it told me, that the file is not damaged. I ran Bandifix nevertheless, but the problem is still the same with the fixed file.
