I have different frame rates. The event I recorded was mostly recorded 
at 25 & 50 FPS. The recordings with 25 & 50 FPS are converted into proxy 
files without any problems. Only the sports close-ups were recorded with 
120 FPS. These cause the error. I will send you a file via your private 
e-mail address, then you can test it. Let's see if you get other results.
