What aspect ratio does TikTok use?

TikTok's native format is 9:16 (vertical/portrait), which fills the entire mobile screen. Videos shot in 16:9 (landscape) will have black bars on the sides unless cropped.

How do I crop a landscape video to vertical for TikTok?

1. Upload your landscape (16:9) video. 2. Select the 9:16 preset. 3. Drag the crop frame to keep the most important part of the scene — usually the center. 4. Export and upload directly to TikTok.

Does cropping reduce video quality?

Cropping itself does not reduce quality — it only removes pixels outside the selected area. The remaining area is kept at full original quality. SuperMotion outputs in H.264 MP4 for maximum compatibility.
