      I have a relatively  complicated scene which involves 2 live video feeds (1/2 PAL) and 2 downstream luma keys on one 720X576 stage (split screen).
      When I enter the scene the video frame rates drop to 10 fps.
      BUT when I open my Isadora Preferences and then close them (don't change anything) the frame rate jumps to 23 FPS or so (more cycles).
      Very strange.

        Dear Eric,

        Have you tried turning up the Target Frame Rate to 50fps? What effect does that have?

            Also, when you say 'luma keys', are these FreeFrame plugins? Or? Send me the patch if you like and I can try on my machine.

              @Mark,

              Dear Mark,

              50 FPS didn't make a difference.  The "luma keys" are CI based, not Free Frame.

              I can send you the patch, but it's a mess.

              I'll first try to see if 1.3.0f24 makes a difference and let you know.

              Thanks you for your time,

              ur,ummmmm,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,eric

                I've cleaned up the patch and changed some settings and now everything seems to be working as expected.  Since I've made so many changes I can't say for sure what the solution was but I think it had to do with the Preferences Default Resolution, and Scaling combined with my Live Capture Settings.
