Seedance 1.5 Pro AI Video Generator
ByteDance's Seedance 1.5 Pro is the cheapest model on this site: four silent seconds at 480p costs 2 credits. It takes a prompt on its own or up to two images alongside it, runs from 480p to 1080p, and has an audio switch you only pay for when you use it.
Two credits is less than a rounding error — use this model to find the prompt, then take it to a bigger one
Why Choose Seedance 1.5 Pro
Every other model on this site starts somewhere between 3 and 15 credits a clip. This one starts at 2 — which changes what you use it for. It is the model you run twenty times to find the shot, not the one you run once and hope.
From 2 Credits a Clip
480p, four seconds, no audio. That is the cheapest generation available anywhere on FlowVeo3, and it is a real clip rather than a preview — same model, same prompt handling, just a smaller frame.
Audio Is a Switch, Not a Tax
Sound doubles the price of a run, so it is off by default. Draft silently at 4 credits for 720p, turn audio on only for the take you intend to keep, and pay 7. You decide per run.
Text Only, or up to Two Images
The same endpoint handles both. Leave the upload empty and it generates from the prompt alone; add one or two images and it works from them. No separate page, no separate price.
A Lock-the-Camera Switch
Under Advanced there is a fixed-lens toggle that holds the frame still instead of adding camera movement. Useful for product shots, talking heads and anything that should look like it was on a tripod.
480p, 720p or 1080p
Three tiers on one page, and the gap between them is large: 1080p costs roughly four times 480p for the same clip. Draft at the bottom, deliver at the top.
Failed Runs Are Refunded
Credits are held when you submit and returned automatically if the generation fails or the provider never answers. A clip that does not arrive costs you nothing.
The Model You Can Afford to Be Wrong On
At 2 credits a run, ten failed attempts cost less than one clip from most models here. That is the whole argument for this page.
How to Use Seedance 1.5 Pro
Because runs are this cheap, the efficient workflow is the opposite of careful: generate early, generate often, and only spend real credits once the prompt has stopped changing.
Write the Shot
Setting, subject, action, camera. Dialogue in quotation marks gets spoken when audio is on. The prompt box holds 20,000 characters, which is far more than you need — long prompts are not better prompts here.
Draft at 480p, 4 Seconds, Silent
2 credits per attempt. Run the same idea three or four different ways and compare them. This is where you discover that the model reads "drifts" differently from "floats", and it costs almost nothing to find out.
Add Images If You Need Them
Up to two, JPEG, PNG or WebP, 10MB each. With images uploaded the aspect ratio setting stops applying — the output takes its shape from the picture instead, which is usually what you want.
Finish at 720p or 1080p, Audio On
Once the prompt is settled, raise the resolution and length and enable sound for the final run: 15 credits for eight seconds at 720p with audio, 45 for twelve at 1080p. Generation takes a few minutes and you can leave the page.
Even Lengths Only
Duration moves in steps of two: 4, 6, 8, 10 or 12 seconds. There is no 5 and no 15 on this model — if you need an odd length or a longer clip, Kling 3.0 Turbo runs 3 to 15 seconds continuously.

FAQ
Pricing, audio, image inputs, clip length and how 1.5 Pro compares with Seedance 2.0.
Seedance is ByteDance's video generation family, and 1.5 Pro is the previous generation's flagship tier. This page runs it through a single endpoint that handles both text-to-video and image-to-video. FlowVeo3 is an independent platform and is not affiliated with ByteDance.
Between 2 and 45 credits, set by resolution, length and whether audio is on. Silent: 2 credits for 4 seconds at 480p, 7 for 8 seconds at 720p, 25 for 12 seconds at 1080p. Audio roughly doubles each of those. The exact cost for your settings is shown before you submit.
Because it is an older generation, not a smaller one. Version numbers and prices move independently at the provider — 2.0 Mini is a cut-down version of a newer, more expensive model, while 1.5 Pro is the full version of a cheaper older one. Try both; the quality difference is not what the names suggest.
Because it doubles what the provider charges us — picture and sound are generated in one pass, and that pass costs twice as much per second. We pass the structure through rather than averaging it into one higher price, which is what keeps silent drafts at 2 credits.
They give the model something to work from instead of generating everything out of the prompt. You can upload up to two, in JPEG, PNG or WebP at up to 10MB each, or none at all. The provider's documentation does not specify what a second image means, so treat two-image runs as experimental — one image is the well-defined case.
It tells the model to hold the frame still rather than adding camera movement of its own. It lives under Advanced and is off by default. Turn it on when the subject should move and the camera should not — product turntables, pieces to camera, static establishing shots.
No. This model accepts 4, 6, 8, 10 or 12 seconds only. For a continuous length slider, Kling 3.0 Turbo covers 3 to 15 seconds a second at a time, and Seedance 2.0 covers 4 to 15.
You are not charged. Credits are held when you submit and released back to your balance if the model fails or the provider never returns a result. Generated videos stay available for seven days, so download anything you want to keep.
