Gource Source Visualization

The following is a little guide to generating a Gource source visualization for ClaimChunk. There isn't a good reason to do this other than it looks cool (this guide is more for my own personal reference).

Gource can be found here.

Output the name of the commits as captions:

git log --pretty='%at|%s' | sort -n > my_captions.txt

Open and start the visualizer:

gource -1920x1080 -e 0.05 --key --title "ClaimChunk" --seconds-per-day 3 --auto-skip-seconds 1 --file-idle-time 0 --max-file-lag 1 --caption-file my_captions.txt --caption-duration 2 --output-framerate 60 --output-ppm-stream source_visual.ppm
(Press escape to exit)

The
--output-framerate 60 --output-ppm-stream source_visual.ppm
can be removed if you don't want to generate a video)

Use FFMPEG to convert to MP4:

ffmpeg -y -r 60 -f image2pipe -vcodec ppm -i source_visual.ppm -vcodec libx264 -preset medium -pix_fmt yuv420p -crf 1 -threads 0 -bf 0 source_visual.mp4

Finally, delete temporary files (del instead of rm on Windows):

rm my_captions.txt rm source_visual.ppm
