    After Effects error:overflow converting ratio denominators (17::18)

    Every time I render a movie I’m geting this error (After Effects error:overflow converting ratio denominators (17::18)) and it happens when prosessing the same frame. It’s not something wrong with this frame because I tried with different video files and I’m always getting this error at exactlly the same frame. My hard disc has enough space, so it is not the problem. What can it be and how I can fix it? Please help me

    It is not solved. Although the process you described will get your footage to work, the length of the footage could change. As an example: I have a .mov file that has a frame rate of 14.99 frames per second, and when I change the interpretation of the footage to ANY number(Even the one the comp already has), it shortens the video length from 59 minutes to 34 with missing footage.

    I had exactly the same problem. I had interpreted the footage, But after I had footage missing? Have you solved this problem?

    Hi there-

    I’ve started receiving this error in After Effects CC. If you click “ok”, to make the error message go away, it simply pops back up again. It is impossible to right click on a clip and change the frame rate. I’ve had this problem only with one clip, from a GoPro Hero 3+ Black. All other clips from the same camera don’t cause this problem, and a different section of the same clip only gave me the error once, so your method of fixing it worked. I’m at a loss.
