image sequence blender
Convert an image sequence to a movie, with weighted smoothing.
Say you have a sequence of images, from a surveillance camera which takes photos at 1fps. If you convert these to a movie, you will see "fast forward artifacts", tiny jumpcuts, if you will. This script attempts to blend neighboring images of a frame to minimize/hide this effect.
- imagemagick (for test.sh)
usage: windowblend.py [-h] [--inglob INGLOB] [--windowsize WINDOWSIZE] [--attack ATTACK] [--ffmpegoutopts FFMPEGOUTOPTS] outfile positional arguments: outfile output file optional arguments: -h, --help show this help message and exit --inglob INGLOB input files glob --windowsize WINDOWSIZE window size --attack ATTACK attack and release length --ffmpegoutopts FFMPEGOUTOPTS ffmpeg output options, like c:v. comma-separated.
Unfortunately, I do not remember how
attack relates to
windowsize. Default is 0, so probably ignore it, run some tests or try to read the source.
Run test.sh, which creates a sequence of test images and runs the script.
I used this for an art project: a movie created from captured surveillance video.
