Review reel of six 360p Omni drafts: one timeline render for 10 cents

To review six 360p Omni drafts as one file, send them to POST /v1/timeline-1.0/render with audio.mode: silence and fit: contain. A reel of up to 60 seconds is one billable minute, $0.10 at the doc's public rate. You watch the shots in order, once, and give notes on the cut, not on six downloads.

Why a reel

Google positions the 360p mode of Omni 1.1 Flash for rapid prototyping and storyboard iteration (Google, read 2026-10-05). A storyboard is judged as a sequence. Six separate files hide pacing, and a reviewer who has to open each one skips some. A single file that plays the shots in order gets a verdict on rhythm and continuity before you pay for finals.

The request

Six 5-second drafts make 30 seconds. Each slot starts where the last one ended. The body below shows two slots; repeat the pattern. contain letterboxes instead of cropping, so you can see the whole frame the model produced. Set output.width and output.height (even integers from 256 to 2160) to the draft's size; read it from a probe if you are not sure (Sume docs: Timeline 1.0, read 2026-10-05).

{
  "audio": { "mode": "silence", "duration_seconds": 30 },
  "output": { "width": 360, "height": 640, "fps": 24 },
  "video": [
    { "source_url": "https://media.sume.com/artifacts/artf_demo/d1.mp4",
      "start": 0, "duration": 5, "fit": "contain" },
    { "source_url": "https://media.sume.com/artifacts/artf_demo/d2.mp4",
      "start": 5, "duration": 5, "fit": "contain" }
  ]
}

Settings that matter for review

POST /v1/timeline-1.0/plan is unbilled and shows billable_minutes before you spend the dime.

Give the reviewer a rule for notes. Ask for a slot number and a verdict, keep or re-roll, plus one sentence of reason. Slot numbers map straight back to your job list, so a re-roll is a lookup, not a search through filenames.

If the drafts mix 16:9 and 9:16, the reel needs a single output size. Pick the orientation of the final delivery and let contain letterbox the others. That also shows how the other format will sit, which is information in itself.

Finally, delete nothing from the reel's inputs until the finals are done: the reel is built from your draft artifacts, and re-planning after a note needs them.

A reel also gives you a number to quote to a client or a teammate: six drafts and one review file cost a known amount, and you can say what a full 720p pass would add before anyone asks for it.

• Silence spine: the reel is for picture. Omni clips carry native audio, but a review of motion does not need it.
• Short hard cuts, no fades: a fade can hide a seam you want to see.
• Set output.fps only after you know the draft's rate; if you omit it, the render follows the sources.
• Keep a shot list outside the file, since the timeline has no labels: slot order is shot order.

What it costs against what it saves

Six 5-second drafts at 360p cost 30 seconds at the draft rate; with the worked rate of $0.0375 per second, that is $1.125, and the reel adds $0.10 (Sume API pricing, read 2026-10-05 and the catalog hold the live rates). One reviewed pass that kills a bad shot saves a 720p re-roll of 5 seconds at about $0.625. The reel pays for itself when it spares you one of those.

After review, mark each shot keep or re-roll, re-roll at 360p, and finish only the keepers. The finals then go on a timeline of their own.
