What a YouTube visualizer actually needs
Four things, in order of how often they go wrong: the full length of the track (not a 5- or 10-minute cap), 16:9 at 1080p so YouTube serves it in HD, no watermark, and a video allowance that does not make the fourth single of the year a budgeting decision. Frame rate is a bonus (60 fps makes fast visuals smoother, 30 fps is fine for ambient ones), and 4K is rarely worth the render time for a static-camera visualizer.
Groovalizer clears all four on Pro for any track up to 15 minutes, with 8 videos a month, and Unlimited drops both the count and the length limit. To try it on a real upload, export free at 720p with the watermark, or buy one clean 1080p video for $4.99, then decide.

Full album uploads
An album stream is the case where per-video and per-minute limits hurt most. Groovalizer Unlimited has no length limit, so a 40-minute record renders as a single file (Pro stops at 15 minutes a video), and Song parts give each track its own look so the visuals move with the record instead of looping one scene for an hour.
Because rendering happens on your machine, a long export takes as long as your hardware takes: leave a laptop on it for a while, the way you would a video editor. Nothing uploads and nothing queues.
Looking like a release, not a template
Most YouTube visualizers share one look: cover art in the middle, a spectrum ring or a progress bar around it. It works, and SongRender and Specterr do it well. Groovalizer makes a different kind of video: the projectM engine rendering fractals, liquid geometry, and kaleidoscopes that react to the actual bass, mids, and treble of the track, which is what you want when the video should feel like the song rather than label it.
Tint the visuals toward your artwork’s palette with the colour controls, or upload an image as a texture so the scene is built from your own cover. For a lyric video, the lyric video page times the words to the song and sets them over the same visuals.
