Sam, thank you !! It is 119.88 fps which is not 120.  I can not believe this but I am glad to get to the bottom of this. Eagle Eyes Igor with the 61 fps discovery.  I was trying all kinds of things yesterday and getting absolutely no where.  gg/phyllis

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.
