I have been testing a composition with two different SDI cameras through 2 Blackmagic UltraStudio Mini Recorders and running into an odd issue. Each camera is being displayed in a separate window. Both cameras use different frame rates. Camera 1 is a PTZ - 1080/29.97p and Camera 2 is a Fixed - 1080/30p. I keep getting a frame and a half green flash every few seconds on Camera 1 and slight pauses in video frame rate on Camera 2. I can understand this happening if I was trying to merge the 2 images somehow but they are each running separately in their own windows and only related by being in the same composition. Just to trouble shoot a bit I ran a second test with two Fixed - 1080/30p cameras and it appears to run smoothly with no pauses or green flashes that I could see, so it doesn't appear to be a bandwidth or computer performance issue that I'm seeing. This clearly seems to be related to the mismatched frame rates even when running in separate windows. Any ideas on wether this is resolvable or not? I would hate to have to find a PTZ - 1080/30p camera when I have this nice one available right now for this project.
