A way to make a video from a frame of another video and audio extracted from a song
Raw
test.sh
# Download and trim audio
# yt-dlp does not work for some reason
you-get "https://music.163.com/#/song?id=1433075058"
mv "0. 惊涛落日（Official Vers.）.mp3" jtlr.mp3
sox jtlr.mp3 jtlr_trim.wav trim 101.25 33
# Download video and extract a frame
# as a .png file to avoid messing with compression
yt-dlp "https://m.youtube.com/watch?v=PJuIWf-sEyA" --sub-langs en --embed-subs -f bestvideo
mv "강아지가 엉덩이를 들이미는 이유 6가지 [PJuIWf-sEyA].webm" src.webm
ffmpeg -i src.webm -vf subtitles=src.webm -ss 00:00:54 -frames:v 1 frame.png
# Generate video
# To make the output's length accurate
# while technically having more than 1 frame (for thumbnail generation on Discord to work),
# we must hardcode the audio length here, for some reason
# (may be unnecessary if the output frame rate is high enough)
# It would seem that the lower the frame rate, the more broken seeking might be in certain video players,
# 1fps is ok on Discord though
ffmpeg -r 1 -loop 1 -i frame.png -i jtlr_trim.wav -c:v libx264 -tune stillimage -pix_fmt yuv420p -c:a aac -b:a 192k -t 33 i_will_protect_you.mp4
# Outputs is just slightly below 1MB, good I guess
