Help & guides
Everything you need to master Corepras CVS — from your first prompt to credit management.
Open StudioGetting started
- Sign in — inner pages require your Corepras account.
- Create a character (optional) — give the AI a description and it generates a reference portrait; or upload your own image.
- Open the Studio, pick a mode and describe your scene.
- Generate — your clip renders in the cloud with native audio and appears in History when done.
Creation modes
Text → Video
Pure prompt-driven generation. Describe the scene, camera and mood.
Image → Video
Upload or extract a start frame; the model animates from that exact moment.
Ingredients
Combine up to 3 saved characters/objects into one generated shot.
Every mode supports resolution (720p/1080p), aspect ratio (16:9 / 9:16), duration up to 10s, negative prompts, seeds and audio.
Characters
Characters keep people, creatures and props visually consistent across clips.
- Describe appearance, wardrobe and personality — AI generates a reference portrait.
- Upload an existing image instead if you already have one.
- Add characters as ingredients in the Studio; reference images are stored on our CDN automatically.
Extending scenes
Any completed clip can be continued: press Extend scene on the result or in History. CVS extracts the exact final frame, switches the composer to Image → Video mode and appends a continuation hint — producing seamless multi-shot sequences.
Credits & billing
CVS runs on prepaid credits:
- 100 credits ≈ $1 of engine time; each render shows its estimate before you submit.
- Purchases are charged in your application currency; packs include bonus credits (+10% / +20%).
- Credits are debited atomically when a render starts and refunded automatically if it fails.
- Track everything on the Usage page; buy more on Get Credits.
Troubleshooting
- Render stuck in "processing"
- Renders complete server-side within minutes. If a job stays stuck after ~15 minutes it is marked failed and any credits are refunded — just try again.
- "Insufficient credits" error
- Your balance does not cover this render's estimate. Top up on Get Credits or lower resolution/duration, then resubmit.
- Character looks wrong in renders
- Use richer descriptions (age, wardrobe, hair, distinct features) and prefer one or two ingredients rather than three.
- Video won't play
- Clips stream from our CDN; if playback fails, re-open History — the file may still be transferring. Download works even while preview fails.
FAQ
Nothing is lost. Renders execute on our servers and the finished video is automatically stored in your library — you can close the tab immediately after submitting.
