DESCRIBE IT.
IV STUDIO WRITES THE REST.
Type the idea in plain words. Write it for me looks at your pictures and videos, writes the full prompt and checks it for mistakes before you spend a render.
Your shot
@Tess waits under a bus shelter in the rain, checks her watch, then smiles as headlights sweep across her face.
A picture of the app’s Create page. Download IV Studio to use it; it runs on your own PC.
02 / How a shot works
Block it out
Drag people and the camera around a top-down floor. It becomes exact screen directions, or a moving grey previs.
Try a few
One to three quick previews render while you watch their steps, ranked by words heard, likeness and sharpness.
Finish the best
Pick one and finish it at full size with DLSS or SeedVR2. Everything lands in the Library, a day at a time.
Make it a film
Drop it on the timeline with your songs and lines, grow it with new footage, and export any shape.
03 / The cost difference
ONE MINUTE OF FILM.
$141 OR ABOUT $1.
A one-minute short is about twelve 5-second shots, and almost nobody gets a shot on the first try. Here is what that minute costs at three takes a shot on today’s leading paid video model, and on IV Studio.
Estimate
Price your film
12 five-second shots · 36 takes
161× less than every take on Seedance 2.5 at 1080p, on a rented GPU.
Why it matters
FILMMAKING FOR
ANYONE WITH A PC.
When a try costs a few cents instead of a few dollars, people experiment, keep going and finish. More of the stories people carry around get made.
Runs where you are
Your own graphics card, or any GPU you rent by the hour. No company has to approve the idea.
Open, not metered
The app is free and open source and runs open-weight models. You pay for power or GPU time, not a toll on every try.
Yours to keep
Footage, characters and projects live on your machine or your own cloud account.
Reported Higgsfield’s own published Seedance 2.5 prices, checked October 30, 2026: 16 credits a second at 1080p, 3 at 480p, $49 for 1,000 credits (Higgsfield). Measured IV Studio on an RTX 4090, November 8, 2026: two draft takes in 95 s and a finish to 2752×1536 in 124 s; RunPod RTX 4090 Secure at $0.89 an hour, November 10, 2026. Estimate About 25 s for each extra take, 10 minutes of pod start-up per film, your own PC drawing 600 W at $0.30 a kWh. Not a quality comparison: Seedance 2.5 is a leading paid model and IV Studio’s shots use the open MiniMax H3 model, so look, resolution and how many takes a shot needs differ.
04 / Recurring actors

05 / Hunt, then finish
