- Click YouTube Preset for a smaller, safer upload.

Best quality without stutter
- Lower Render scale first (0.85× helps a lot).
- Keep Trails moderate and reduce Particles if needed.
- Use VP8 codec for smaller files and better compatibility.
- Use Auto Tune as your baseline, then tweak.
Troubleshooting
- Black preview: load audio, then click Play once (browser may require a user gesture).
- Audio choppy in export: reduce load (Render scale 0.85×, 30fps, Auto complexity, fewer particles/trails).
- Export file too large: lower Video bitrate (2–4 Mbps) and prefer VP8.
- Light theme looks dark/black: use Theme Light + Light mode fix Auto or Boost.
Privacy
