How do I change the size/quality of the scrubber sprites?

I saw something at Configuration - Stash-Docs, but the instruction if vague and the only place I see ffmpeg-arguments is for transcoding.

Values are hardcoded. You would need to update the code and build binary yourself.

pkg/scene/generate/sprite.go

          const (
          	spriteScreenshotWidth = 160
          
          	spriteRows   = 9
          	spriteCols   = 9
          	spriteChunks = spriteRows * spriteCols
          )

This has now been addressed in the latest dev build:

Supercedes #6522. I chose to raise a new PR rather than pushing to the existing …one since it was largely a rewrite. Resolves #4023 Adds the following new settings: - sprite screenshot size - use sprite interval flag, to enable using the fields below. This is defaulted to false so that existing systems are unaffected. - sprite interval - the time between sprites - minimum sprites - maximum sprites <img width="1195" height="828" alt="image" src="https://github.com/user-attachments/assets/ac974b23-ccde-4cb5-854c-01dbdddd9191" /> Sprite generator uses the legacy interval settings if `use sprite interval` is false. Otherwise, it uses the sprite interval, adjusting it if the number of sprites is outside the minimum or maximum. An interval of 0 means that it will be calculated based on the minimum sprites. The number of sprites generated is adjusted up to the nearest perfect square so that there is no empty space in the generated sprite image. Also adjusted the sprite generation code to correctly handle portrait videos, which were generating based on the supplied width instead of the longest dimension, resulting in overly large sprite images. Examples of sprite files generated with the default custom options shown above: 2:15 video <img width="640" height="360" alt="image" src="https://github.com/user-attachments/assets/7867dd56-a0d0-4fac-b6cc-28918a27e460" /> 0:19 portrait video <img width="360" height="640" alt="image" src="https://github.com/user-attachments/assets/efce6789-deb6-4521-8151-ddc98489d339" /> Sprite previews in the scene page are sized based on the configured sprite size. Here is an example at 320px: <img width="1233" height="502" alt="image" src="https://github.com/user-attachments/assets/68765ea9-3b25-4114-a702-f9812455a9c6" /> vs default: <img width="1235" height="364" alt="image" src="https://github.com/user-attachments/assets/d1450b79-a4df-4735-b219-e2eb45cffa3f" />
