Ad hook test matrix: 4 hooks x 2 ratios on Omni Flash, priced

Eight draft clips, four hooks in two aspect ratios, cost $1.50 at 360p for 5 seconds each. Re-rendering the two winners at 1080p adds $1.875, for $3.375 to a tested pair.

A 16:9 and a 9:16 version are separate jobs on Omni; the model offers only those two ratios and does not reframe one into the other.

The matrix

Finals

Two winners at 1080p, 5 seconds: $0.9375 each. If the same two also need the second ratio, add $1.875.

Running it

• Name each job's Idempotency-Key from hook and ratio, e.g. hook-a-916, so you can retry safely.
• Eight submits fit in the accepted-job capacity of Pro (24) and up, but not of Free (6): on Free, send in waves of up to six and expect 429 queue_full on the seventh. Queued jobs are normal, not a failure; retry a rejected submit with the same Idempotency-Key once a job finishes.
• Judge sound at the draft stage, since the audio is part of every hook.

Why the draft pass is cheap

At 360p a 5-second Omni Flash clip is $0.1875; at 1080p the same clip is $0.9375, five times as much. Drafting all eight cells at 360p costs $1.50, while drafting all eight at 1080p would cost $7.50. The draft pass exists to pick a winner, so spend the 1080p money only on the cells you will ship.

Omni Flash accepts 3 to 10 seconds, so 5 seconds fits with room to lengthen a winner. 360p, 720p, 1080p and 4K are the resolutions in the catalog.
