  1. Hi Guys,

    I have some Dashcam video files that I wish to crop.
    The Dashcam has a very wide view and I wish to concentrate the viewer's attention to the important parts of the scene.
    The files are quicktime mpeg-4 .mov
    I will paste below the output of MediaInfo for one of the files.
    Any recommendations appreciated.

  2. Crop to a fixed region or a fixed size that moves around in the video frame?

  3. Good question.

    A fixed region would be easiest, black borders would be best, and there is no need to maintain aspect ratio.
    But out of curiosity, would the software choice be different for a region that changes when the scene changes?

    TIA

  4. Using almost any advanced NLE, zoom in and control the X-Y position with keyframes. It's called the Ken Burns Effect.
