What to watch out for on TikTok
- The bottom 480 pixels are the riskiest real estate on any platform. Nothing readable belongs there.
- Captions added inside TikTok land in the same zone, so plan for them instead of fighting them.
- Exporting above 1080p rarely survives compression in any visible way.
