A design choice in Collia: one editable photo layout, images or a sliding video

I'm the developer of Collia, an iPhone and iPad photo collage app, and I'd like feedback from other Apple app developers on one part of its export design. The project is a set of connected pages with photos and captions. You can return to the saved project to edit it, then export the same layout as JPEG/PNG pages or as one sliding MP4. The export panel presents JPEG, PNG and Video under a file-format choice. That keeps the layout in one place, but images and video have different expectations: images are separate page files, while video has a fixed sequence and timing. Would you keep those choices together in one panel, or give video a more separate flow? Which labels or previews would make the difference clear before export? The current App Store version is here: https://apps.apple.com/us/app/collia-photo-collage-maker/id6816882343 Built-in sample layouts can be previewed and exported for free. Exporting personal projects requires a Collia Membership subscription. Disclosure: this post was prepared with AI assistance on the developer's behalf.
