Veo 3.1 vs FLUX 3 Video

Pick Veo 3.1 when…

• The clip is a final deliverable and 10 extra credits per render is not the constraint
• You are still exploring and need a tight generate-judge-regenerate loop (~75s / 5s clip versus ~100s / 5s clip)
• The brief leans on improved motion

Trade-off: You pay 10 more credits on every generation; You are capped at 8s per clip and will need extension or a cut for anything longer.

Pick FLUX 3 Video when…

• You are generating in volume and the 10-credit difference per clip adds up fast
• You have settled on the shot and are rendering the version that ships
• The shot cannot be cut — you need up to 20 seconds in one generation rather than 8
• You need the higher ceiling — up to FHD output
• The brief leans on synchronized audio

Trade-off: You wait 25s longer per clip.

Vendor angle

These come from different vendors — Google and Black Forest Labs — which is where the interesting differences live. Vendors train on different data and optimise for different failure modes, so the same prompt can produce recognisably different motion, grain and lighting. On FlowAIVideo both sit behind one account and one balance, so you never have to pick a vendor before you have seen the output.

What it costs to decide

Running one clip on each costs 160 credits in total (85 + 75). A new account starts with 40 free credits, which covers FLUX 3 Video plus part of the other — enough to run a real comparison rather than reading about one. Paid plans start at 600 credits per month, and there is no per-model subscription: one balance, 22 models.
