I have used CompositeVideoSimple example as video source for 5.8GHz FPV transmitter, but it does not work correctly. The signal is there but it is somewhat unstable. I can see part of the image on one frequency, another part on another frequency, sometimes whole image for a few seconds. I have tried 3 different transmitters a none of them work and when I use common camera as a source the image is crystal clear. Tried to change PAL/NTSC, resolution but it does not help. Looks like something is out of sync. Can you recommend me some parameter I could try to change ? Thank you...

Hi, I have found the solution. Switch to NTSC and change .shortVSyncMicros from 2.3 to 4.3 fixes everything
