SeedVR2 10x video upscale vs Sume's upscale tool

fuser.studio's upscaler roundup lists SeedVR2 for video upscaling at 1x to 10x scaling and places it in the generative class. Sume exposes a video_upscale_create tool on its hosted MCP, but the public docs do not state its scale factors, so read the tool schema before you plan a 10x job.

What generative upscaling means

Generative upscalers synthesize detail rather than only sharpening what is there. That can recover texture on soft footage, and it can also invent detail that was never in the source, such as skin texture or text. The more aggressive the factor, the more the output depends on the model's guess.

What Sume documents

video_upscale_create appears in the hosted MCP tool list next to image_upscale_create and rmbg_create. The video generation docs also say 2K and 4K upscales are priced when requested on minimax-h3. Nothing in the docs gives a maximum factor or a list of upscale models for the tool, so do not assume parity with SeedVR2.

Check the schema before you commit

Ask the server instead of guessing. tools_schema returns the input schema for a named tool, and tools_list shows the subset visible to your session:

• Call tools_list and confirm video_upscale_create is visible to your session
• Call tools_schema for it and read the accepted fields
• Run a dry run (dry_run=true) to preflight cost before a paid submit
• Keep an idempotency_key on every paid call

Generate at the size you need

If you need an upscale beyond what the tool offers, a pragmatic route is to generate at a higher resolution in the first place. Several catalog models list 1080p, and Gemini Omni Flash 1.1 lists 4K, which avoids a second pass altogether.
