Flux 3.0 — Frequently Asked Questions
How much does Flux 3.0 cost?
It depends on resolution. A 5-second clip costs 48 credits at 480p and 172 credits at 1080p. Visualix AI prints the exact cost on the Generate button before you commit, and refunds automatically if a run fails.
How long can a Flux 3.0 video be?
Flux 3.0 handles up to 20 seconds in a single pass — selectable lengths are 5s, 10s, 15s and 20s. For longer pieces, generate several shots and cut them together in the editor.
Does Flux 3.0 generate sound?
Yes. Flux 3.0 produces synchronised audio alongside the picture — ambience, effects and, where the prompt calls for it, speech. No separate sound pass is needed.
Can I animate my own image with Flux 3.0?
Yes. Upload a still and Flux 3.0 animates it, and you can supply an end frame to control where the shot finishes. Image-to-video generally gives you far more control over composition than describing the same scene in words.
What resolution does Flux 3.0 output?
480p, 720p and 1080p. Anything you generate can be pushed to 4K afterwards with the video upscaler.
Can Flux 3.0 make vertical video for TikTok and Reels?
Yes — Flux 3.0 supports 16:9, 9:16, 1:1, 4:3, 3:4 and 21:9, so you can generate natively vertical 9:16 footage rather than cropping a landscape render.
Do my credits expire?
No. Unused credits expire at plan renewal/expiration. There is no throttled "unlimited" tier and no queue that slows down the more you use it — you see the price of each generation and pay that.
