express DV levels to broadcast levels
a local production house edits on a Mac with express DV 3.5 and outputs to a BVW-75. the beta dubs that I receive from them have set-up at 0 IRE. I usually boost that to 7.5 using an external TBC. Are there any settings that the editor at the production house can use on his Avid to output legal black levels?

Somewhere in the settings (I’m not near my XPress) is a setting called “use NTSC setup”. Maybe in general, or media creation, I forget.

Thanks Jon. We looked at it and “NTSC has set up” is checked. It looks like the only way to get everything legal is to color correct each clip. My editor friend is going to push for ver. 4.6. At least it has a video input tool.

Here’s a question you need answered by the production house. Are they digitizing from DV using firewire? If so, DV has 0 setup. Same goes for SDI. The only way around that is to digitize via an analog connection which is where 7.5 IRE setup lives. If they are outputting to a BVW-75, then they are connection via s-video or composite. They could run the AVID out connection through an analog TBC and put black where it belongs on the BetaSP. Of course, there’s the possibility that they are giving you super black in case you need to do any effects work old-school style (lumanance keys).

Thanks for the info Wayne. They are going to and from the Avid via a DSR-25 deck (firewire). The DSR-25 feeds the Beta deck. Would the DSR-25 have menu selectable set up on the composite output? If not I’ll take a TBC over there next week and try that route.

I don’t remember the menu settings on a DSR25 off-hand. I don’t think there is a setting, though. It just works as a pass-thru. Bring the TBC with you anyway. What’s the worst that could happen, you bring it home again?
