Is there an event when the comp's color depth/pixel format is changed?

Is there any way I can detect the change in color depth in a composition?
I know I can react differently by calling PF_GetPixelFormat() on render to find out the current bit depth/format, but I was wondering if there is any way to detect and react to the event when a user changes the color depth of the composition manually?
Basically, what I want to do is hide/change parameters in the ECW depending on the bit depth.

Any help appreciated 🙂

you can use PF_UpdateParamUI during the render call to force AE to refresh the UI,

you can also hide/unhide params at any time using AEGP_SetDynamicStreamFlag and AEGP_DynStreamFlag_HIDDEN.

I think the frame is re-rendered when the comp depth is changed, you can put your check in Render or Pre-render.

Yes, the frame is indeed re-rendered, but I can't change parameter properties in Render, only when receveing events or PARAMS_UI_CHANGED
