I'm a little wary of downloading what appears to be closed-source software and running it, especially if I don't know if it's something I'd be interested in using.
Otherwise, it's a really cool idea (I LOVE the old winamp visualizers).
The footage in the trailer shows what the music videos look like. All of it is recorded directly from the app, and there's a section where the UI is hidden and it's mostly effects and transitions going on (that's the music video part). In hindsight I might not have made that part clear enough.
Also, the old winamp style visualizations were super badass! They played a huge part in my interest in audio visualization :-)
If so, does it do other things or just anime girls?

I'm not sure if the trailer loading is an issue on the site - could you check the console for me and see what it says?
In your case I see you are using a webm container. iOS prior to version 15 does not support webm natively. Then earlier this year they started adding support for parts of webm in iOS 15. https://9to5mac.com/2021/08/10/apple-adding-webm-audio-codec...
I recommend converting the video using ffmpeg.
The following should give you a video file that will be playable on most mobile devices, even quite old ones.
ffmpeg -i preview.webm \
-c:v libx264 -crf 23 -profile:v baseline -level 3.0 -pix_fmt yuv420p \
-c:a aac -ac 2 -b:a 128k \
-movflags faststart \
preview.mp4
See https://developer.mozilla.org/en-US/docs/Web/HTML/Element/so... for details on multiple sources in the video element. I.e. what changes you need to make to your html.
What, the static anime girl with a ken burns pan and zoom?
