Render a 2-6 second 3D-style video clip from a scene description. Choose from 7 styles (photorealistic, Pixar-like, low-poly, wireframe, isometric, voxel, claymation), set camera motion, and render on our A100 GPUs in 30-180 seconds. MP4 output, no watermark, royalty-free for commercial work. For downloadable 3D mesh files (GLB / OBJ for Blender / Unity / Unreal), see /3d/.

Name materials (glass, wood, metal, polished concrete), lighting (window, neon, golden hour), and one clear camera move per render.
Need a downloadable 3D model? This tool outputs MP4 video — visually 3D-styled but flat-screen. For downloadable mesh files (GLB / PLY / OBJ for Blender, Unity, Unreal), use /3d/ or /image/3d/ — those return real 3D assets via TRELLIS.

3D-styled video without the Blender learning curve

Real 3D in Blender / Cinema 4D / Unreal takes hours-to-days per shot — model, rig, animate, light, render. Free.ai 3D Video renders the final frame straight from a description in about 90 seconds, with seven distinct 3D-aesthetic presets covering photorealistic product renders, Pixar-style characters, low-poly indie-game moodboards, wireframe technical reveals, isometric SaaS infographics, voxel-art retro pieces, and claymation. The trade-off: no per-frame edit control, no mesh export, no scene re-rendering from a different angle. For mesh export use /3d/ which returns downloadable GLB / OBJ via TRELLIS.

Product hero shots

Photorealistic close-up renders for D2C product launches. Slow orbit / pull-out reveal. Drop-in for Shopify hero sections without a Blender artist.

SaaS explainer animations

Isometric room cutaways are the SaaS explainer-video signature. Drop a clip into your landing page hero or onboarding video.

Game dev moodboards

Low-poly + voxel previews communicate art direction to your team / publisher / Kickstarter backers before any modeling work begins.

Engineering reveals

Wireframe rotating shots for hardware-startup pitches, conference demos, patent-application visuals.

YouTube + TikTok intros

3-second logo-stinger intros / outros. Pixar-style for kids channels, voxel for gaming, photorealistic for review channels.

Architecture previz

Photorealistic fly-throughs of buildings before construction. Iterate in minutes vs days in Lumion / Twinmotion. Final renders still belong in those tools.

AI 3D Video — FAQ

Free.ai AI 3D Video Generator renders 2-6 second clips with 3D-style aesthetics - photorealistic, cartoon / Pixar-like, low-poly, wireframe, isometric, and voxel-art. It is not a Blender replacement (no mesh export), but it produces the final-frame MP4 in under two minutes for storyboarding, social content, and concept work.

Yes - self-hosted CogVideoX on our A100s, about 7,500 tokens for a 3-second clip inside the daily pool. Free accounts get 10,000 tokens on signup. For actual 3D mesh export (GLB / OBJ) see /3d/ and /image/3d/ - those use TRELLIS and give you downloadable models, not just video.

No - AI 3D Video outputs MP4 video only, not a 3D model file. For mesh export (GLB / PLY / OBJ suitable for Blender, Unity, Unreal), use /3d/ or /image/3d/ which call TRELLIS on our GPU3. Those return downloadable 3D assets and a preview render.

Blender (free) / Cinema 4D ($94/mo) / Unreal (free for most) are real 3D software - full control, hours-days of work per shot. RunwayML ($15+/mo) ships some 3D-adjacent features bundled with its video platform. Free.ai 3D Video is the fastest path from text to a 3D-looking clip - under 2 minutes, zero learning curve, zero license cost. Trade-off: you cannot edit individual vertices or re-render the scene from a different angle.

Photorealistic: architectural walkthroughs, product renders. Cartoon / Pixar-like: family content, kids channels, app demos. Low-poly: game dev moodboards, indie mobile-game aesthetics. Wireframe: engineering / technical content. Isometric: SaaS explainers, infographics. Voxel: Minecraft-adjacent, retro game aesthetic.

No - AI video models refuse named-person and licensed-brand prompts for trademark reasons. Describe the character by features instead: "a red-haired rogue in leather armor, fantasy style" works; "Aragorn from Lord of the Rings" does not. Same for logos - describe the shape, not the brand name.

2-6 seconds. For longer 3D-style video projects, render multiple 3-second clips and assemble in /video/editor/ or CapCut. Professional animated shorts are always multi-shot assemblages; no model reliably renders coherent 30-second 3D scenes yet.

Pick from static, orbit, pan, zoom-in, or fly-through. "Orbit" works exceptionally well for product-shot framing. "Fly-through" suits architectural / game-world previz. "Static" suits social-media product hero shots where movement would distract.

Kaiber ($5-125/mo) generates stylized videos - closest competitor but no 3D-specific presets. Pika Labs has strong 3D-like output on Pro ($30/mo). Gen-3 Alpha ($35/mo) renders 3D-cinematic quality but costs per clip. Free.ai gives you 3D-style video on self-hosted CogVideoX for free, plus per-use premium access to Seedance / Kling without a monthly subscription.

No - VR / AR needs stereoscopic 3D or actual 3D mesh, not 2D-plane video with 3D aesthetic. For VR asset creation start with /3d/ (TRELLIS mesh export) then import into Unity / Unreal. AI 3D Video is for flat-screen output only.

Somewhat - re-use the same style preset + style cues in your prompt ("low-poly isometric, same character as before, now standing in a forest"). AI video lacks true memory so exact-match character consistency is a known limitation. Mitigate by rendering all clips in the same sitting with anchored prompt language.

Yes - POST /v1/video/generate/ with a 3D-flavored prompt. Same endpoint as /video/. Bearer auth, monthly limits. Snippets at /api/.
