Hello Again

I have been using VMIX with a wide range of cameras, mostly high end broadcast stuff HD 1080i / 59.94hz (For US projects) & SD 576i 50hz for UK project. Just starting a Project in 720p, and using Sony BRC-Z330 cameras. They can be set for 1080p or 720p, and are currently set to my project of 720p. The four cameras are connected using a Decklink Quad, with the latest drivers from the Blackmagic Website.

When I view the cameras using Blackmagic Media Express, They report that they are outputting 1280 x 720 @ 50hz Progressive - exactly what I expect. I can see the preview input from the camera, and its picture perfect.

However when I add thm as an input in VMIX (selecting 1280 x 720 50p as the required resolution) i broadly get a black picture. I broadly because every once in a while I will see a single frame flash from the camera.

I can't yet confirm yet with 100% that this is exclusively a 720p problem, but I haven't had issues with any other cameras or resolutions, including the BRC-Z330's little brother (The BRC-300 576i SD), and its Big Brother (BRC-700 1080p HD).

Anybody else had 720p issues? anybody else using any 720p SDI cameras with a Decklink Card?

All The Best
