Upscaling
Upscaling enlarges a generated image or clip after the fact, inventing the extra pixels with a second model. It is how a 720p render becomes a 1080p or 4K deliverable without being regenerated.
Upscalers are a separate class of model from the generator. They add plausible detail rather than real detail, which is usually invisible on a photographic subject and very visible on text, faces at small scale and fine repeating patterns.
The alternative is to generate at the size you need in the first place, which usually costs more per second of video but avoids the artefacts entirely.
On eroq
For clips, eroq's own upscaler, eroq Upscale, is coming soon to Video › Edit, for a render or an upload of up to 30 seconds, frame rate and sound kept. eroq Motion One and Seedance 2.5 also sell 1080p and 2K as tiers of their own, rendered at their native size and then upscaled. Or pick an engine that renders the size natively: up to 4K on Seedance 2.0, Veo 3.1 and Veo 3.1 Fast; up to 2K on Hailuo 3; up to 1080p on Veo 3.1 Lite, Grok Imagine and Wan 3.0; up to 768p on Hailuo 3 Max; up to 720p on Seedance 2.5, Seedance 2.0 Fast, Seedance 2.0 Mini, Kling and Runway Gen-4.5. Images render at their model's native size: there is no image upscaler.
Questions
Can I upscale an eroq render to 4K?
Not to 4K: eroq Upscale, coming soon, stops at 2K. For a 4K deliverable, render it natively on Seedance 2.0, Veo 3.1 and Veo 3.1 Fast, the engines that sell 4K, or upscale elsewhere, in your editor or a dedicated tool.
Which engines render 1080p?
Natively: Motion Pro, Seedance 2.0, Veo, Hailuo 3, Grok Imagine and Wan 3.0, and Seedance 2.0, Veo 3.1 and Veo 3.1 Fast go up to 4K. eroq Motion One and Seedance 2.5 reach 1080p and 2K through their upscale pass, and eroq Upscale, in Video › Edit, will take any clip there once it opens. The others stop lower: up to 768p on Hailuo 3 Max; up to 720p on Kling, Runway Gen-4.5, Seedance 2.0 Fast and Seedance 2.0 Mini.
Does a bigger render cost more credits?
On video, usually — clips are priced per second by engine and resolution, so Seedance 2.0 is 64 credits a second at 720p and 158 at 1080p. Veo 3.1 charges the same for 720p and 1080p, and an image costs the same at every size.
