H3 Max video generator FAQ topics
What is H3 Max?
This site runs MiniMax H3 Max Turbo, fal's post-trained variant of the open-weight MiniMax H3 video model, served by fal.ai. It generates 5-15 second clips with native audio. H3 Max Studio is an independent tool that lets you generate these videos with simple credit pricing.
How fast is generation?
We publish no latency benchmark of our own. Generation time depends on queueing, prompt expansion, and render time. fal's API reports backend inference time via a timings.inference field, but that excludes queueing and delivery — see the sources below.
What resolutions are supported?
480p and 768p, both generated natively. 480p is great for fast drafts and storyboards; 768p is best for final publishing. Higher resolution costs 1.6x credits.
What aspect ratios are supported?
16:9 (YouTube landscape), 9:16 (TikTok/Reels/Shorts vertical), 1:1 (square), 4:3, and 3:4 — pick the ratio your platform needs.
Does H3 Max include audio?
Yes. H3 Max Turbo generates native audio together with the video, so you generally do not need to add a voiceover or sound design step separately.
Can I use my own image?
Yes — switch to image-to-video and paste a public image URL. H3 Max animates the image with subject-motion and camera movement.
How do credits work?
One credit equals one 480p video-second. A 5-second 480p clip costs 5 credits; 768p costs 8. A paid monthly invoice adds one monthly allocation. A paid yearly invoice adds 12 allocations upfront. Unused credits stay in your balance.
What happens if I run out of credits?
Your generation pauses until you buy a top-up or upgrade. Your past videos stay available in your account.
Is there a free trial?
Account creation is free, but generation requires purchased credits. This site does not currently grant free signup credits. Any free promotions on fal's own tools are separate.
Who owns the videos I create?
You do. Generated videos belong to you and can be used for commercial content, subject to the model provider's terms.

Model, capabilities & limits
The model this site actually runs, what is only available upstream, and the sources we verified — so you can check them yourself.
- Model used here
- MiniMax H3 Max Turbo — fal's post-trained variant of MiniMax H3, served through fal.ai's minimax/h3-max-turbo text-to-video and image-to-video endpoints.
- Naming
- MiniMax H3 is the open-weight base video model. H3 Max is fal's post-trained variant. H3 Max Turbo is fal's higher-throughput variant. All three are video models — unrelated to any language model.
- Resolution
- 480P and 768P, both native. The base H3 also offers 2K/4K upscales of a 768P render; H3 Max and H3 Max Turbo do not.
- Duration
- 5–15 seconds at 24 FPS (fal's H3 Max Turbo endpoints; the open-weight H3 model card lists 4–15 seconds).
- Aspect ratios here
- 16:9, 9:16, 1:1, 4:3, and 3:4. The upstream schema also lists 21:9, which this site does not expose.
- Audio
- Native audio is generated together with the video, so sound and picture stay in sync.
- Image input
- Paste a public image URL (used as the first frame). The upstream endpoint also accepts an optional last frame via end_image_url — not exposed in this site's UI.
- Reference-to-video
- Available upstream on H3 and H3 Max (H3 Max's reference endpoint arrived after its launch). This site does not offer a reference-to-video mode.
- Generation speed
- Vendor-reported only. fal's API returns a timings.inference field (backend denoising time); end-to-end wait adds queueing, prompt expansion, and delivery. This site runs no latency benchmark of its own.
- Weights
- H3 has open weights (33B parameters, MiniMax H3 Community License). H3 Max and H3 Max Turbo list no separate weights release — API only.
