Qlab and Masks, Please help me understand one thing
Today I tried to use a black/white PNG mask (created in MadMapper, 1920x1200, irregular shape) on a Stage in QLab for a live camera cue.
At first everything works perfectly.
But the moment I change the Cam Cue Geometry from “Fit Stage” to “Custom” in order to scale/adjust the image, the output changes not only for the live video itself, but apparently also for the mask. The mask gets transformed/distorted together with the content, which defeats the whole purpose of precise projection masking.
This made me wonder about QLabsi nternal rendering order.
It seems to behave like this:
Video + mask
→ render combined image
→ apply geometry/distortion to the entire canvas
Whereas I would expect something more like:
Video
→ apply geometry/distortion
→ render final image
→ apply mask as final output layer
Is this a bug of the video engine? Cant imagine Im the first person running into this?
