- The video leaves the game in high quality. The loss comes later: every app squeezes an upload down to a few Mbps, and busy moments (clouds of sparks, lots of tiny moving dots) turn blocky. Particle Explosion off ( advanced settings) gives a visibly cleaner result.
- Record at 1080×1920 (Creator Pro). A 720p video looks soft on a phone screen.
- Re-encode only once: in CapCut export 1080p, 30 or 60 FPS, a high bitrate. Upload from your computer when you can — messengers and "storage saver" copies compress it again.
- Switch on the HD / "highest quality" upload option in the app. A fresh upload also looks soft for a few minutes, until the app has finished its HD version.
Free plan: up to HD (720p), 30 FPS, High quality and 192 kbps audio. Full HD, 60 FPS, Maximum quality and 256 kbps need Creator Pro.
