gloop

Finds as-seamless-as-possible loops in image sequences.

Usage

Compute similarity metrics

Use gloop.compute_metrics to compute pairwise similarities.

The -s/--size parameter will make computation likely much faster.

python -m gloop.compute_metrics images/*.png -o info.json -s 256

Find best loop

Use gloop.find_loop with the aforegenerated information file to find a suitable sequence for looping.

The output is a file suitable for passing into the Ffmpeg concat demuxer.

python -m gloop.find_loop -i info.json --min-length=20 --min-score=0.95 --frame-duration 0.04 --loop 3 > concatfile.txt

Generate a video

Use ffmpeg with the aforegenerated concatfile to generate a video. The below example uses minterpolate to generate a 60 FPS video out of lower-framerate content.

ffmpeg -f concat -safe 0 -i concatfile.txt -vf minterpolate -pix_fmt yuv420p tanzen.mp4
