Question / Help Duplicating frames


New Member
I'm recording a video of a video. I know it can lose some quality when you record over another video, but it's really important that I do it. The video i'm recording over is at 50fps. My obs settings are at 50fps. When I look at the video I just recorded it looks to be a mixture of 50fps and duplicating frames. Going frame by frame confirms this. Every 2 seconds or so there is a frame that is just like the previous one. I have checked if there is something wrong with the video I'm recording over, but that video is 50fps with no duplicating frames.

Is there something wrong with my OBS or is it just not possible to record over a different video without getting duplicating frames?
