Resolution is where most of the cost and most of the disappointment in a Wan 2.2 render comes from, so it is worth deciding deliberately rather than taking whatever the form defaulted to. Here the output band is part of the route you call — the Wan 2.2 text-to-video route is named with its size — so the resolution is not a free-floating slider you set after choosing a model.
Naming the route after its output size makes the cost visible before you commit: you can see which band you are calling at a glance instead of discovering it after a render. It also keeps comparisons honest. When two runs differ only in the band, any change in the output is attributable to the band and nothing else.
The trade-off is flexibility: you cannot keep the same route and simply raise the size. You switch routes, which means the model call changes too. That is worth knowing before you build a workflow around a specific band.
The expensive mistake is iterating at final size. Prompt iteration is where most renders get thrown away, and every one of those is paid for at whatever band you chose.
Judging a small render as a proxy for the large one has limits: artefacts that are invisible at a low band can become obvious once the same shot is rendered larger. Use the small render to judge composition and motion, not fine detail.
Cost depends on the model, the resolution and the duration, and the credit cost of your chosen settings is shown beside the form before you submit. Read it there — it is the authoritative number, because it reflects the route and settings actually available at that moment rather than a figure copied onto a page. Credit prices are on pricing.
If you have not settled on a band yet, run the prompt on more than one and compare at the same seed; that is the cheapest way to learn what your particular shot needs.
Resolution is one of four decisions in a Wan 2.2 render, alongside the prompt, the seed and the duration. If you are still choosing between generations, the Wan 2.2 model page covers which routes this version exposes. If you are starting from a still image rather than a description, Wan 2.2 Animate is the image-to-video route. The Wan workspace is where the live controls and the current credit cost are.
Can I render small and upscale afterwards? You can, but check the result: upscaling recovers size, not detail that was never there.
Why can't I just change the resolution on one route? Because here the band is part of which route you call, not a separate setting.
Where is the real cost figure? Beside the form, before you submit. That reflects the routes actually available at the time, so it outranks any number written on a page.
Where do I start? Open the Wan workspace and pick the Wan 2.2 band you want to render at.
