Who Builds Video Upscaler

Seedance is ByteDance's breakthrough generative video model family — built by the team behind TikTok's world-class recommendation and visual intelligence stack. Seedance 2.5 and 2.0 excel at 60 FPS cinematic motion coherence, realistic human physical dynamics, complex multi-subject interactions, start/end keyframe interpolation, and reference video motion transfer without the typical warping or uncanny artifacts found in earlier generative models.

Best suited to

As the fast tier, Video Upscaler is a strong pick for storyboarding, prompt iteration and volume social content where turnaround matters more than peak fidelity.

Video Upscaler — Frequently Asked Questions

How much does Video Upscaler cost?

It depends on resolution. A 10-second clip costs 9 credits at 1080p and 35 credits at 4K. Visualix AI prints the exact cost on the Generate button before you commit, and refunds automatically if a run fails.

How long a clip can Video Upscaler upscale?

Video Upscaler handles up to 60 seconds in a single pass — selectable lengths are 5s, 10s, 15s, 30s and 60s. For longer footage, upscale each shot and reassemble the edit.

Does Video Upscaler change the content of my video?

No. Video Upscaler increases resolution and recovers detail — it does not re-generate the shot, so framing, motion and timing stay exactly as they were. Audio on the source clip is preserved.

Should I generate at 4K or upscale afterwards?

Upscaling is almost always cheaper. Generate at 1080p to iterate quickly, then upscale only the take you are keeping. Models with native 4K such as LTX 2.3 Pro and Seedance 2.0 are worth it when fine detail has to be genuinely resolved rather than reconstructed.

What resolution does Video Upscaler output?

1080p, 2K and 4K. 4K is the point of the tool — detail is reconstructed rather than simply stretched.

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.
