Hi people
I'm uploading music mixes on my youtube channel, and I want to use a looped animation as video.

(couple of examples: https://www.youtube.com/watch?v=_hNYXw4H3SI&t=8s - https://www.youtube.com/watch?v=GTmqRYTvkHo )

To make this, I usually render a long video with After Effects and then upload it. But it takes time.
Does any of you know a quicker solution?

I checked https://www.tunestotube.com/ but seems to work only with static images. Something like this but with animated gifs would be perfect.
