boy, you picked a wacky forum to post this on. Why didn't you try the AVID forum if this is an AVID type question.

Patch bays do not "screw up" the sync signals. You need the correct sync type to be going to both your AVD Nitris (or Adrenaline) and your VTR, if you expect to output to that VTR without issue.
Using a video patch bay is completely acceptable.

You get an AJA GEN10 (for example) that can generate both NTSC composite black, as well as tri level sync for 23.98 (at either 1080 or 720). You use a video DA to distribute the composite black signal to all the Reference Inputs to your Nitris boxes and VTR Reference inputs (of course, on the patch bay, so you can break the normal with a patch cord.). Then when you want to get 1080 23.98 tri level sync into a particular VTR and Nitris box, you just patch it in.

So, the genius who said that you should never do this - what is his suggestion - to go behind the racks, and unplug the NTSC composite black reference, and use long BNC cables to patch in the correct tri level sync as necessary ?

Everyone thinks that they are an expert. There is absolutely nothing wrong with using a patch bay to accomplish this.
