Prepare Videos

1. Download videos from a .txt containing the links yt-dlp -f "bv*[ext=mp4]+ba[ext=m4a]/b[ext=mp4] / bv*+ba/b" -a urls.txt
2. Cut video from timestamp to timestamp

ffmpeg -i input.mp4 -ss 00:05:10 -to 00:15:30 -c:v copy -c:a copy output2.mp4

3. Convert to h264

for i in *.mp4; do ffmpeg -i "$i" -c:a copy -c:v libx264 "${i%.*}_h264.mp4"; done

Scenes and Config

fog-steps and water-steps encode the following values:

<start delay>-<on time>-<off time>

<start delay> is the initial delay in seconds after the scene starts. Then the following loop starts: Output is on for <on time> seconds and then off for <off time> seconds. This loop runs till the end of the scene.

So 1-1-5 waits at the beginning 1s, is then 1s on and 5s off and then again 1s on and 5s off again and again until the end of the clip.

To disable it completely set the value to 0 (not 0-0-0).
