Trello accepts files up to 10 MB. If your video is bigger, SelfKit shrinks it right in your browser so it fits — as sharp as the limit allows.

How to send a video on Trello
- 1
Choose your video above — Trello is already selected.
- 2
If you have a paid Trello plan, pick it to use the bigger limit.
- 3
Press “Compress video” and download the result.
- 4
Upload it to Trello as usual.
Common problems
- The upload is rejected as too large
- Compress the video with the Trello preset: the result is always checked against the limit.
- The video looks blurry
- A long video in a small limit gets little data per second. Trim it to the important part first or pick a bigger plan.
- The video does not play
- SelfKit always saves MP4 (H.264) — it plays on every phone and computer.
