    Split your video file into multiple parts using different methods:
    1. Free Split: Specify a list of comma-separated time stamps to split the video into segments.
    2. Average Split: Enter the number of parts to divide the video into, with each segment having equal duration.
    3. Time Split: Provide a list of comma-separated time stamps to split the video, with each segment starting at the specified time.
    4. Size Split: Enter the target size of each segment in megabytes. The video will be divided into segments with sizes close to the specified value.
