PLS ANSWER: CapCut export settings for highest quality on TikTok? (filming in 4K/60fps)

I film my videos in 4K at 60fps and edit in CapCut, but I feel like my quality sometimes drops after uploading to TikTok.

What export settings are you guys using in CapCut for the best possible quality on TikTok?

Resolution (4K vs 1080p?)

Frame rate (keep 60fps or drop to 30?)

Bitrate settings?

HDR on or off?

Would love to know what actually works for you!
