3. Image Inputs: Use stable, publicly accessible URLs for start, end, and reference images.
4. Video Edit Input: Verify that the source video is between 3 and 10 seconds before submitting it.
5. Reference Limits: Submit no more than 10 images and 3 videos, and keep every reference video at or below 3 seconds.
