    Check exact frame rate

    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?

    mediainfo seems not to be installed on a vanilla Ubuntu Studio..? I got other tips about ffplay and ffprobe which agree with my MacBook on the 23.99 fps and 29.97 fps.

    Yes it is not installed by default.
    Or you can use ffmpeg, as you already did.
