AVIMux Fails to build complete video !

[olimori12]

Hello ! So when i was recording games i couldnt hear my voice , just the game sound and i found out using AVIMux fixes the issue so i did and it actually works but the problem is that it only make the video up to 3 min and 3 seconds  , and the original video is actually almost 9 minutes . Any idea how to solve it ? Heres a screenshot of my dxtory , you can see on the sceenshot video length 8 min and 40 sec , but for some reason it only does up to 3 min and 3 sec and then it says ' complete ' . Let me know if you have a solution ! Thanks !

What are you trying to do with your video ?  If you're re-encoding before upload, there are better options than Avimux.

If you simply want to check to make sure all audio streams are intact you can try VLC
