Seedance V1 Pro Fast I2V: Image to Video Online
Bottom line
Higher-quality first-generation Seedance image animation: 5 or 10 seconds at 720p or 1080p, no 480p tier. Upload a starting frame, choose Seedance V1 Pro Fast I2V in the Image to Video tool, and animate it on VdoBloom — the credit price appears before every generation.
Seedance V1 Pro Fast Image-to-Video is the higher-quality sibling to V1 Lite, from ByteDance's original Seedance generation. It shares the same minimal interface — pick a duration of 5 or 10 seconds, upload an image, describe the motion — but skips the 480p tier entirely, starting at 720p and topping out at 1080p. Like Lite, it's image-to-video only: there's no text-only mode and no reference-video input.
That narrower resolution range is the whole positioning. Pro Fast is for when 720p is already your floor, not your ceiling, and you'd rather not have a 480p option cluttering the choice. It costs more per clip than Lite at matching resolutions, but the gap is modest, and the two-decision interface (duration, resolution) stays identical.
It carries VdoBloom's HOT content label, the platform's most permissive filtering tier, shared with Seedance 1.5 Pro and V1 Lite in the same older Seedance generation. Pricing is flat per duration-resolution combination and shown before you generate; a failed job is refunded automatically.
What it costs on VdoBloom
Flat per-combination pricing: 720p/5s = 7 credits, 720p/10s = 15; 1080p/5s = 15, 1080p/10s = 29. Notably, Pro Fast's 720p price (7-15 credits) actually undercuts V1 Lite's 720p price (9-18 credits) for the same durations — the difference between the two models isn't a strict price hierarchy, it's that Lite additionally offers a cheaper 480p tier Pro Fast doesn't have.
V1 Pro Fast vs V1 Lite I2V
Same interface, same 5-or-10-second structure, same image-only input, same HOT content label. The only real differences are resolution range (Pro Fast: 720p-1080p; Lite: 480p-1080p) and price at 720p, where Pro Fast is actually cheaper. If you never need 480p, there's little reason to pick Lite over Pro Fast; if you want a cheap draft tier first, Lite's 480p option is the one thing Pro Fast can't do.
What creators use Seedance V1 Pro Fast I2V for
- Animating product or portrait photography straight into 720p or 1080p without a 480p detour.

- Comparing directly against V1 Lite on the same source image to see if the extra cost is worth it for your use case.

Frequently asked questions
What does Seedance V1 Pro Fast cost?
It's flat-priced per duration and resolution: 720p is 7 credits for 5 seconds or 15 for 10 seconds; 1080p is 15 credits for 5 seconds or 29 for 10. There's no 480p tier. The price for your choice is shown before you generate.
Is there a free trial for Seedance V1 Pro Fast?
No dedicated trial, but New VdoBloom accounts start with 10 free credits, enough for at least one 5-second 720p clip (7 credits) to see how it handles a given image.
Does Seedance V1 Pro Fast support text-to-video?
No — image-to-video only, the same as V1 Lite. You upload a starting image and describe the motion; there's no prompt-only mode on this model.
Why doesn't Seedance V1 Pro Fast offer 480p?
It's positioned as the higher-quality tier of ByteDance's original Seedance image animators, starting where Lite's range ends (720p) and going up to 1080p. If you want a cheap 480p test first, V1 Lite is the model for that — Pro Fast assumes you're going straight to a usable resolution.
How does Pro Fast compare with Seedance V1 Lite on price?
It costs more at matching resolutions: 7-29 credits across its 720p/1080p range versus Lite's 9-40 for the same two resolutions plus a cheaper 4-8 credit 480p option Pro Fast doesn't have. The gap at 1080p is small (15/29 vs 20/40), and at 720p Pro Fast is actually cheaper (7/15 vs 9/18) — worth comparing directly since the tables aren't strictly one-sided.
Is Seedance V1 Pro Fast censored?
VdoBloom rates it HOT, the platform's most permissive filtering tier, same as V1 Lite and Seedance 1.5 Pro. Platform rules still apply to what generates.
Is Seedance V1 Pro Fast open source?
No, it's a proprietary ByteDance model available only through VdoBloom's hosted tools.
Should I use this or Seedance 2 for image animation?
Use Pro Fast for a simple, cheap 720p/1080p pass with only two settings to pick. Use Seedance 2 if you want per-second duration control (4-15s instead of just 5 or 10), a wider aspect-ratio set, 4K, or the ability to steer motion with a reference video.
