The 575 has a self setup to bars function I use that to double make sure I'm within where my luma and chroma should be. This is just incase I'm slightly off on the BVH.

Signal chain: Composite out from BVH-2000 to DPS-290 (comb filter to S-Video), into Blackmagic Analog to SDI for cable/space reasons, then Leitch DPS-575 for distro, waveform monitoring, to auto setup bars to confirm luma/chroma. SDI into Teranex 2D for upscaling, then to UltraStudio 4K for capture.

I feel attacked. lol
