My file upload fails

It is almost always a file that is too big or a format the tool does not take. Try in this order:

1. Check the format: MP4 for video, JPG or PNG for images.

2. A file from an iPhone (HEIC or MOV)? Convert to JPG or MP4 and try again.

3. Check the tool's limit: next to the upload field it says how many files and what length it takes. For example, Seedance 2.5 reference clips must be 2 to 30 seconds.

4. Shorten or shrink the file and try again.

If the engine rejected a reference image in its content check, you are not charged. Which tool did this happen in?
