slitscan

(fork from https://git.io/vF9pm)

Python video slit scan generator based on OpenCV

Generates a color strip of a given image sequence and returns the result as image object.

Using OpenCV, this function creates a color slit scan from the given input file. By default, the average color of 5 frames is condensed into one stripe in the output image.

If you encounter errors, this is probably due to unsupported video formats. Check if your Python OpenCV bindings are compiled using ffmpeg. If not, you have to manually compile OpenCV with Python bindings including ffmpeg. This is usually true for Linux and OS X because the PyPi installed OpenCV bindings do not support ffmpeg for these plattforms. The Windows version does support ffmpeg, but with the limitation of LGPL licensed code. If in doubt, convert your video to uncrompressed AVI or comparable.

Testet with Python 3.6, should work back to 2.7, too. After installation, use the command line phrase "slitscan -h" to learn about the features.

Feel free to contribute!

This is a new script. If you know python, please make the script running more smooth and faster.

Roadmap:

• parallelisation for faster and smoother script running
• progress
