Seedance 2.5 Money-Saving Workflow: Reroll at 480p, Upscale Selected Clips to 4K

On September 22, @HeyAmit proposed and tested a low-cost 4K workflow for Seedance 2.5. The core idea is to push the expensive step to the very end: generate and re-roll at 480p resolution, pick the satisfactory clip, then use a single Creative Upscale pass to bring it to 4K. @mhdfaran subsequently relayed and promoted the same method. Per the author's accounting, a 10-second video averaged over 5 re-rolls would cost about $9 if generated entirely at 720p; doing 5 re-rolls at 480p costs about $5 ($4), plus one 4K upscale ($4 plus $1), for a lower total cost—and the final delivery resolution is actually higher, with cost savings of up to 87%.

Confirmed

Four steps: set resolution to 480p before generating; re-roll at 480p, adjusting any unsatisfactory camera moves or expressions; pick the satisfactory clip; click Creative Upscale, choose 4K, and apply.
The accounting: for the same 10-second shot with 5 re-rolls, 720p throughout costs about $9; 5 exploration runs at 480p cost about $4$5, plus one 4K upscale ($4+$1), for a lower total cost with a 4K final output.
The 4K price depends only on when the upscale is requested, not on the generation stage.

Why it matters

This method moves the "re-rolling" stage from high resolution down to 480p, dramatically cutting trial-and-error costs—ideal for creators who need many re-rolls.
Cost drops while delivery resolution actually rises (4K), balancing quality and budget.
