What file types can I upload?

Four asset types, no format anxiety: upload the export you have, including the heavy masters, and it plays for everyone.

Four asset types cover a project:

• Video: any common format your camera or editing app produces, from phone clips to ProRes and DNx masters. There is no format picker because there is nothing to pick; upload the export you have and every viewer can play it. Size caps are per plan (2 GB Free, 10 GB Pro, 25 GB Team); the practicalities of big masters live in Upload large files.
• Image: stills, boards, frames, references. They sit in projects and review links alongside video.
• Audio: mixes, VO takes, music options, with the same commenting your video gets.
• Document: PDFs and similar reference material, so the brief can live next to the cut.

One deliberate boundary: presentations are their own surface, not project assets. A PDF deck, a PowerPoint, or a wrapped Google Slides goes in through Presentations, where it gets a slide viewer and per-slide analytics instead of a video player.

If an upload is refused, it is nearly always the per-file size cap rather than the format; the caps and what to do are stated plainly.
