A strong mobile video starts with deliberate framing. The destination may process uploaded media, so review its current help and upload interface. Prepare for the actual screen and keep important content away from controls and edge crops.
Compose for a tall screen
Keep the main subject visible in a vertical frame. If converting horizontal footage, crop intentionally and check that action at the sides remains understandable.
Protect captions and UI text
Platform controls can overlap the lower and side areas. Preview text on a phone and keep subtitles legible without covering faces or key objects.
Check current upload requirements
Duration, dimensions, size and encoding recommendations can change. Confirm the current guidance in the app before export.
A practical checklist
- Select a vertical placement and frame the shot.
- Check current upload guidance.
- Export a copy and preview it in a phone-sized frame.
- Confirm captions, music, voice and crop before posting.
Common mistakes to avoid
- Scaling landscape footage vertically without choosing a meaningful crop.
- Putting subtitles behind platform controls.
- Assuming a downloaded preview is identical to the final post.

Why does text look soft after posting?
