The AI Video Tool: Picking the Right Engine on WorkCrafter
A guide to WorkCrafter's AI video generator — Standard, HD and Ultra engines plus the Cinematic, Dynamic, Flow and Surge premium families, prompt tips, credit costs and limits.
The video tool turns a prompt (or an image) into a short clip. It offers the widest engine range on WorkCrafter because video is where quality, speed and cost diverge the most. This guide groups the engines so you can pick with confidence, and covers the prompt habits that matter more for video than anything else.
The engine families
Pick an engine per generation. They fall into a few families — you never need the backend details:
- Automatic (best available): let WorkCrafter choose. Start here.
- Standard / HD / Ultra: the core tier — Standard for fast drafts, HD for everyday quality, Ultra for the best of the core engines.
- Cinematic (HD, Plus, Max): premium, film-like output for hero clips and ads where look is everything.
- Dynamic (incl. Pro, 4K, Turbo): strong motion and action; Turbo trades some quality for speed, 4K for resolution.
- Flow (incl. Pro, 4K): smooth, coherent movement — good for camera moves and flowing scenes.
- Surge (incl. Fast, Mini): quick generations when you're iterating on ideas rather than finalising.
- Director / Omni: flagship engines for the most demanding shots.
“Iterate on a fast engine, finalise on a premium one. Video is the most expensive tool per run — don't polish a bad idea at flagship quality.”— WorkCrafter
Prompt for motion, not just a picture
The mistake most people make is describing a still image. Video engines need to know what moves and how the camera behaves. Cover:
- Subject and setting: what's in the shot and where.
- Motion: what the subject does, and how fast.
- Camera: static, slow pan, push-in, orbit, handheld.
- Style and light: cinematic, documentary, golden hour, neon.

Keep clips short and intentional
Shorter clips hold together far better than long ones — coherence, physics and faces all degrade as duration grows. Generate two good seconds rather than six shaky ones, and cut several short clips together in an editor for anything longer. This also keeps costs down while you find the shot that works.
Image-to-video
Starting from an image you generated (or uploaded, where supported) gives you far more control over the look than describing everything in words. Nail the frame first with the image tool, then animate it — the video inherits the composition you already like.
What video engines are still bad at
- Long takes — quality and coherence fall off quickly, so keep clips short.
- Precise hands, faces and text, especially in motion.
- Complex multi-step actions — one clear motion per clip works best.
- Exact continuity across separate clips — plan cuts rather than expecting a seamless long shot.
What it costs
A video generation costs 50 credits (1 credit = $0.01) — the most of any tool, which is why drafting on a fast engine first pays off. Failed generations are refunded automatically.
Frequently asked questions
Which engine should I finalise on?
For a hero clip or ad, a Cinematic engine; for motion and action, Dynamic; for smooth camera moves, Flow. Draft on Surge or Standard first, then re-run your best idea on the premium engine.
Why does my clip look warped or jittery?
Usually the clip is too long or the prompt asks for too much motion at once. Shorten it, simplify to one clear movement, and regenerate.
Can I make a full video with it?
Yes — by generating several short clips and editing them together. Treat the tool as a shot generator, not a one-click film maker.
Start filming
Open the video tool, draft a short clip on a fast engine with a clear motion and camera move, then finalise your best idea on a premium engine. Cut several short clips together for longer pieces.
