H3 Max Recast in paid ads: what fal says on commercial use

Can you run an H3 Max Recast video as a paid ad? On fal's model page, read on 2026-10-04, "Commercial use" is listed as a feature of the model. That is all the page says: it carries no licence wording, and the terms sit behind the footer's Terms of Service link. So the model side is a yes with the fine print unread, and the rest of the checklist is yours.

Sume serves the same model as h3-max-recast on its Video Router. The swap replaces the people in a 5 to 30 second source video with the people in 1 to 4 reference photos, one photo per person.

Three rights the model line does not settle

A model's commercial-use flag speaks about the model's output. A Recast ad also carries three inputs the flag never touches.

The soundtrack travels with the swap

fal's API schema describes the output as the recast video "with the source sound". A stock clip with a licensed track stays licensed only as far as that licence goes, and Recast does not replace it. If the audio is the weak link, swap the soundtrack on the finished clip before it ships.

A short pre-flight

• Read fal's terms once and file a copy with the campaign; the page itself will not be your record.
• Keep one signed release per reference photo, naming the use (paid social, the markets, the dates). The release checklist and the California digital-replica checklist cover the paperwork side.
• Store the job id of every clip you publish next to its source file and release, so a takedown request can be answered from one row.
• Price the run before you submit it: on Sume a clip bills $0.375 a second at 768p or $0.5625 at 1080p, so a 12 second 768p swap is $4.50.

None of this is legal advice, and the platform you advertise on may add its own disclosure rules. The narrow claim of this page is only that a feature flag on a model page is the start of the check, not the end of it.
