Command Line Video Splitter

Simple command line Python script that splits video into multi chunks. Under the hood script uses FFMpeg so you will need to have that installed. No transcoding or modification of video happens, it just get's split properly.

Run python ffmpeg-split.py -h to see the options. Here are few samples of how it could be used:

Spliting video into equal chunks

python ffmpeg-split.py -f big_video_file.mp4 -s 10

This splits big_video_file.mp4 into 10 chunks. Each chunk will be suffixed with numeric index, for example big_video_file-0.mp4, big_video_file-1.mp4, etc.

Splitting videos into unequal chunks

In order to create unequal chunks of a video, you'll need to create manifest.json.

manifest.json

[
    {
        "start_time": 0,
        "length": 34,
        "rename_to": "video1"
    },
    {
        "start_time": 35,
        "length": 22,
        "rename_to": "video2.mp4"
    }
]

Afterwards run:

python ffmpeg-split.py -f big_video_file.mp4 -m manifest.json

This splits big_video_file.mp4 into 2 video files, video1.mp4 and video2.mp4. The video1.mp4 is a 34 seconds clip, starting from 0:00 to 0:34 of the big_video_file.mp4.

Alternatively, you can use a manifest.csv file to accomplish the task above.

manifest.csv:

start_time,length,rename_to
0,34,video1
35,22,video2

Manifest Options

• start_time - number of seconds into the video or start time
• length - length of the video in seconds. The end time of the video is calculated by the start_time plus the length of the video.
• rename_to - name of the video clip to be saved
• end_time - end time of the video
