jumpcutter

Automatically edits videos. Explanation here: https://www.youtube.com/watch?v=DQ8orIurGxw

Some heads-up:

It uses Python 3.

It works on Ubuntu 16.04 and Windows 10. (It might work on other OSs too, we just haven't tested it yet.)

This program relies heavily on ffmpeg. It will start subprocesses that call ffmpeg, so be aware of that!

As the program runs, it saves every frame of the video as an image file in a temporary folder. If your video is long, this could take a LOT of space. I have processed 17-minute videos completely fine, but be wary if you're gonna go longer.

I want to use pyinstaller to turn this into an executable, so non-techy people can use it EVEN IF they don't have Python and all those libraries. Jabrils recommended this to me. However, my pyinstaller build did not work. :( HELP

Building with nix

nix-build to get a script with all the libraries and ffmpeg, nix-build -A bundle to get a single binary.

Example Setup

using virtualenv

    cd jumpcutter
    virtualenv --python python3 env
    source env/bin/activate
    pip install -r requirements.txt

Example Usage

Jumpcut

regular speed for talking and 99,999,999% speedup during silence, original at 60fps python jumpcutter.py --input_file slow_meme.mp4 --sounded_speed 1 --silent_speed 999999 --frame_margin 2 --frame_rate 60

Lecture Speedup

bit faster talking and 500% speedup during silence, original at 60fps python jumpcutter.py --input_file dull_lecture.mp4 --sounded_speed 1.2 --silent_speed 5 --frame_margin 2 --frame_rate 60

Expectations

Temporary files are placed in a new directory called 'TEMP'
Default output file is [file_name]_ALTERNED.[file extension]
Time to process a 6min video of 1346x904@60fps using H.264, AAC on a MacBookPro took 9min 45sec. Nearly 1:1.5 video to processing time
