When only scaled proxies are used, switching back to the original file doesn't update the preview in the timeline
- Import a supported .MOV clip into a blank project, without any proxies
- Insert it into the timeline and seek to view the quality in the viewer
- Right-click the media library's clip, generate a scaled (fast) proxy at 500x500 max, notice the lower quality (which is fine and expected, the important is to notice that the viewer reflects the quality change)
- Right-click the clip, tell it to "not use Scaled proxy for selected asset"
Result: the low-resolution preview from the scaled asset remains in the viewer, the timeline doesn't reset the asset to the original source clip.
Note: I think this doesn't happen when you go from Scaled --> Optimized, only when you go from Scaled --> Original.
