Topview T1 vs Seedance 2.5: Specs and Costs

The short version

Topview released T1 in October 2026 as its own video model. The company puts it next to Seedance 2.5 and describes it as comparable quality at 38% of the official price. That sentence is a vendor claim, not a measurement, so the useful work is comparing what each model publishes and what a usable clip actually costs you.

On paper, both handle text-to-video and image-to-video, both reach 30 seconds, and both accept reference material. The practical differences are price per second, the number of aspect ratios, and how much third-party tooling already exists around the model.

What each model publishes

Two caveats on that table. First, "published" means the vendor documents it, not that we have reproduced every row. Second, T1 is newer, so its public documentation is thinner — that is a documentation gap, not proof that a feature is missing.

Where T1 has the edge

Price at 1080p. Topview prices T1 at $0.22 per second for 1080p, against $0.585 for Seedance 2.5 on the same page. Thirty seconds is the comparison both vendors use: $6.60 against $17.55. If your brief needs several takes, that difference buys the second and third attempt.

Six aspect ratios. T1 covers 16:9, 9:16, 1:1, 4:3, 3:4 and 21:9. Vertical for Shorts, square for feeds, and 21:9 if you are cutting something that looks like a scope frame. Fewer models force you to letterbox or re-frame in the edit.

Long single clips. A 30-second clip is available without stitching two generations together. For a dialogue scene or a slow camera move, that matters more than any per-second saving.

Where Seedance 2.5 still leads

Ecosystem and tooling. Seedance 2.5 has been available longer, appears in more third-party tools, and its editing and extension endpoints are documented. If your pipeline depends on retaking part of an existing clip, check that first.

Documentation depth. BytePlus publishes generation details that Topview has not yet published for T1. When a spec is missing, the honest position is "unknown" — which is what we print on our own pages.

The pricing math on this site

We convert at $1 = 100 credits. T1 costs 12 credits per second at 720p and 22 credits per second at 1080p, so:

Packs are one-time purchases: $9.99 for 999 credits, $49.99 for 5,199, $99.99 for 10,999. Nothing renews, and unused credits stay on your account. The studio shows the exact cost before a run starts, and a failed or canceled task returns its credits.

How to test both on one shot

1. Pick a shot with a hard detail. A product label, a logo, or text on a sign. This is where models diverge fastest.
2. Keep the prompt identical. Same subject, same action, same camera instruction. Change one variable at a time.
3. Count attempts, not seconds. Run each model until you get one usable clip, then divide total spend by usable clips. A model that needs six attempts is not the economical choice.
4. Check the frame, not the vibe. Watch for warped text, drifting geometry, and motion that ignores your instruction.

That last metric is the only one that survives contact with a real project. Vendor comparisons tell you where to start; they cannot tell you which model suits your footage.

Where this leaves T1

T1 is worth trying first when you need a 30-second 1080p shot at a published per-second rate, and you are willing to check each clip instead of trusting a quality claim. It is not the right first choice when your workflow depends on editing an existing clip or on a mature third-party toolchain.

Either way, price the shot you will actually publish. The per-second number is the beginning of that calculation, not the end.
