30-second AI video, with sound
Describe a shot, or write it beat by beat, and PrismPoster renders it as video with its own sound. The Premium engine holds one continuous take of up to 30 seconds in 5 frame shapes, up to 4K. The Standard engine renders fast 4–10-second shots up to 4K on every account, free included. No subscription.

Made on the Premium engine
Real renders, each with its own sound
Three takes rendered on the Premium engine from written briefs: a three-beat move on one continuous shot, a vertical close-up, and a cinematic 21:9 tracking shot. None of them is stock, and none of the sound was added afterwards.
Point at a clip to hear the sound it was rendered with.
Free tool
Script to video, beat by beat
Write the take the way an AI film maker writes a shot list: a line of action and a length for each beat. The builder times the script, checks it against each engine, prices it at every Premium quality and opens it in the Video studio. Nothing renders until you press Generate.
Take length
15s
Fits one Premium take of 15 seconds.
The Standard engine renders one shot per render, up to 10 seconds, so this script would be 3 renders cut together on the timeline.
| Quality | Credits |
|---|---|
| 480p | 270 credits |
| 720p | 600 credits |
| 1080p | 750 credits |
| 4K | 1,050 credits |
The script opens in the Video studio's brief. Timed beats render as one continuous take on the Premium engine.
Standard or Premium
Two engines, one studio
Every render lands in the same Library and cuts on the same timeline, so you can pick the engine shot by shot: Standard for fast shots and 4K, Premium for long takes, cinematic frames and sound you can steer.

How it works
AI film maker: from a brief to a finished video
- Step 1
Write the shot
Describe one moment, or write timed beats such as 0-4s and 4-9s. On Premium the beats render as one continuous take.
- Step 2
Steer it
Attach up to 30 reference images, 10 clips and 10 sound tracks, or set a start and an end frame.
- Step 3
Pick the frame and quality
Choose one of 5 frame shapes and a quality up to 4K. The price is on the button before you render.
- Step 4
Finish on the timeline
Continue a clip from its last frame, add music, captions and titles, and export a server-rendered master.
FAQ
Questions about the AI video generator
How long can an AI video be?
One Premium render is a single continuous take of 4 to 30 seconds. A Standard render runs 4, 6, 8, 10 seconds. Longer videos are cut from several takes on the timeline editor.
Does the AI video generator make sound?
Yes. Both engines render sound together with the picture. On Premium you can attach up to 10 reference tracks to steer it, and on the timeline you can replace it or mix music under it.
Is there a free AI video generator?
Within limits. In many countries a new account gets 200 free starter credits with no card, enough for a 10-second Standard clip at 720p. Unused starter credits expire 24 hours after they are granted.
What is the difference between Standard and Premium?
Standard is fast and on every account: 4, 6, 8, 10-second shots up to 4K. Premium, which opens with any credit pack, renders one continuous take of up to 30 seconds in timed beats, 5 frame shapes and up to 50 references.
Can I try the Premium engine for free?
Every account gets one Premium draft before its first credit pack: 5 seconds at 480p for 90 credits, paid like any render. After any credit pack you can master it once in 1080p.
How much does a Premium video cost?
Premium bills per second at the quality you choose: 18 credits at 480p, 40 at 720p, 50 at 1080p and 70 at 4K. A 10-second 720p take is 400 credits, shown before you render.
How do I generate an AI video?
Describe the shot or write timed beats, add reference images or a start frame if you have them, pick a frame shape and a quality, and render. The price shows on the button before you spend anything.
What is the best AI video generator?
There is no single best; it depends on the shot. PrismPoster puts two engines in one studio: Premium for one continuous take up to 30 seconds with sound, Standard for fast 4, 6, 8, 10-second shots up to 4K.
Can I edit or extend a Premium clip?
Yes, in the Video studio. An edit bills the source clip's seconds plus the new ones, at 11 to 30 credits a billed second depending on quality, and shows the price before you confirm.
