I record small music videos with my iPhone4 and create the video in Ubuntu Studio 12.10 and Kdenlive. However, the iPhone decides automatically which frame rate to use and I can't figure out if it's 24 and 30 fps or 23.99 and 29.97 fps.

When I check the clips in Ubuntu Studio it tells me the files are 24 and 30 fps. When I check the same files on my MacBook it says they are 23.99 and 29.97 fps. Since Kdenlive have different project settings for 29.97 and 30 fps project I suppose it would make a difference depending on what I choose. I would like to avoid any sync issues with the actual music file when syncing the video clips to the musical score.

How can I check the movie clips to be sure of the exact fps of the file?
