Inspired by a chiptune topic on ZeroNet I downloaded one of the songs shared using youtube-dl but wasn't satisfied with the quality of the video encoding. The song on the other hand was great. And thankfully the author's website was still up so I could download the original MP3 and creating a new video.
I spent a few hours learning FFMpeg from the comfort of the chair behind my Invisible Arch. The manpages for FFMpeg include tons of diagrams and examples so cobbling something together wasn't as hard as I'd expected. Once I was satisfied with the result I transitioned over to my 2019 Mac to share the video…
Womp womp! No sound on macOS and no video in Telegram.
Not sure if I did something wrong but here's how I created the video:
- Find an original MP3 of your favorite chiptune.
- Find a cool video to compliment it.
- Use ffmpeg to create the finished product.
The ffmpeg work was done in 3 steps:
Loop 8s video enough times to exceed length of 275s song:
# 275s / 8s = 34.375 ffmpeg -stream_loop 35 \ -i the_drive_by_visualdon_WIDE.mp4 drive35.mp4
Mux audio and video files, clipping to shorter of the two:
# copy codecs into MP4 container and trim length ffmpeg -i drive35.mp4 -i fod_Rollingdownthestreet.mp3 \ -c copy -map 0:v:0 -map 1:a:0 -shortest muxed.mp4
Finally, add a start and end fade to the video:
# fade based on total frames and framerate ffmpeg -y -i muxed.mp4 \ -vf fade=in:0:48,fade=out:6572:48 \ -acodec copy katamari-drive.mp4
I placed the MP4 container under OSBD which means no attribution is required and no license needs to be carried around in addition to the original works. The art may be used under the grants made by their respective copyright holders:
