    Hi! Registering just to bump this issue, as I'm also seeing it on a Philips Hue Entertainment setup with a Pi 4B running Hyperion 2.0.0-alpha.8.


    Seems to be related to slow image resolution / scale processing for USB capture input - The higher the input resolution, the higher the delay.


    My USB capture device defaults to 1920x1080, and this leads to an approx. 1s delay between the video feed shown in the preview and the Hue lights actually changing colour. Changing the 'Size Decimation' value has no effect on the delay. Smoothing is turned off.


    I fixed this locally by forcing my capture device into a low resolution (720x480) and setting 'Size Decimation' to 1, so that Hyperion isn't doing any resolution/scaling work at all. This removed all lag and gave me near-instant response between the preview and the lights.


    Let me know if you require any logs or would like me to add a GitHub issue.
