Rotoscoping, billed by the frame
Holdout turns film and video frames into alpha mattes. You say what to isolate — in words, or by clicking it — and get back per-frame alpha, ready to composite. It is built for working VFX artists and small post houses. Access is by invitation.
What you get
- Per-frame alpha — PNG frames carrying the matte as their alpha channel, downloaded as a sequence.
- An MP4 of the matte for quick review and client approval.
- Fine-edge matting tuned for hair and fur, with temporal handling so edges hold still across a shot.
- Frames or clips — upload a JPG/PNG sequence, or one MP4/MOV and we extract the frames for you.
Pricing
| Item | Price | Notes |
|---|---|---|
| Delivered frame | €0.03 | Charged per frame we successfully deliver. |
| Frame that fails | €0.00 | Never billed. You pay only for output you receive. |
| Single-frame preview | €0.00 | Test a shot before committing the sequence. |
| Extra render node | €0.15 | Optional, each. Splits a shot across more GPUs to finish sooner. |
A 250-frame shot costs €7.50. No subscription, no minimum spend: you buy credit up front and it is drawn down per delivered frame. Prices are in euros; VAT is added where applicable.
Turnaround. Most shots finish within minutes of rendering starting. A GPU is started on demand, which adds a few minutes when the farm is cold. Times vary with frame count, resolution and load, and are not guaranteed.
Payment
Credit is bought by card through Stripe. Card details are entered on Stripe's own checkout page and never reach our servers. Credit appears on your account as soon as Stripe confirms the payment, and unused credit stays there.
