Comment 73 for bug 520941

Thanks for your investigations and observations.

A lot of people refer to 30fps when the actual rate is 29.97. This is probably due to manufacturers 'dumbing down' and thinking that it is easier to call it 30 rather than 29.97...but the difference between 29.97 and 30fps works out to over 100 frames per hour.

There are built-in profiles for both 29.97 and 30fps within Openshot.

Admittedly it would be nice if Openshot identified the file and set the profile accordingly, which would avoid many problems, but until then, it would be worth double checking with ffmpeg what the true frame rate is.
