codec problem (mostly audio)
I’ve captured some footage with a little software called Bandicam, which captures my PC screen with incredible performance thanks to it’s Nvidia’s CUDA support. They just took their website down and no support is available at the moment.
Now I’m trying to edit this footage in Premiere, but Premiere is having hard time interpreting its audio. The video looks OK, but the audio is completely incomprehensible. Like it is in slow down or something.
I’m not sure if it’s a codec problem. If tell Bandicam to not use CUDA it will let me edit the footage just fine, but there will be a huge drop in performance and especially in file size. The thing is, with CUDA settings, I’ll have a definitive solution if I wanna capture hours of footage, so I really don’t wanna to give up on this for another codec.
The footage runs fine on VLC, Media Player and all. The problem occurs just with Adobe softwares – Premiere/AE/Media Encoder – they all will have this same problem.
I’ve ran the file on mediainfo to try determine what’s wrong with the audio, but I’m not an expert. It looks like a regular MPEG codec for me.
In a last resort I would just try to convert the footage to another format I know Adobe will get it right. But I already have 5 hours of captured material and It would save me tons of time if I can just work on them directly on Premiere.

Try dropping the raw file(s) into AME – export audio only to 48k .wav file.
Bring new audio file into Pr and merge with the video.
