Duplicate frames & incorrect framerate #20

In many videos, the playback speed is significantly slowed down. This can be detrimental for models learning to recognize violence.

I wonder whether it would be possible to go back to original playback speed, without manually sifting through all the videos. I opened a random video and noticed quite some duplicate frames: could it be that I just have to remove the duplicate frames and stay at 30 FPS playback speed?

In the readme you mention the clips are sliced to 5 seconds / 30 fps, how was this done exactly? Was the source always 30 fps or higher? Or did some upsampling happen there as well?
