DV to Beta black levels
I have to shoot/deliver 6 spots for a client’s regional cable campaign. The budget got cut so instead of shooting Beta SP, I’m going to use my Sony HVR-V1U in DVCam mode. The cable company wants a Beta master. I’m concerned about the 7.5 vs 0 setup issue. What do my beloved bovine buddies suggest I do about black levels so I don’t get grief from the broadcaster?
I’m editing on a MBPro using FCP 5.14. I’ll be going Firewire into the Mac and Firewire back out through the camera using it’s component output into the Beta deck. Should I just tell them that it’s setup to 0 or try to manipulate it to 7.5 on the Beta master?
Thanks for sharing your experience.

7.5 setup is for composite video only, there really is no setup on digital tape and yrb component video. Just check your RGB levels in your scope in FCP. O (0mv) is black (in composite it becomes 7.5ire)and 100 (700mv) is your max white across all 3 RGB channels. If you keep your levels between 0-100 RGB then you are within legal broadcast gamut..

Most cameras that have the option of Setup (dv and dvcam as well as hdv) are set to 7.5 i’ve noticed.
You know what though? In the end it doesn’t really matter any more. Though any work I do is always checked and proper.
The broadcasters have become so relaxed when it comes to levels etc, the only thing I’ve seen rejected was because it had a visual glitch from a bad tape dub.
I’ve seen so many garbage looking commercials with overblown or inadequate audio levels. its so very common now.

Have you used the broadcast safe filter to achieve legal video and if so do you have a suggestion for the preset?

When i need to legalize video i just use the RGB limit filter in FCP6/color correction. if you set the upper limits (chroma/lum)to 100 and lower to 0, this will only allow the legal broadcast gamut. I’ve never really liked the broadcast safe filter, at times its not aggressive enough and still leaves you with unwanted levels. The RGB limit literally kills all illegal broadcast levels that you would not see at broadcast anyways and keep’s the TV station trolls off your back…
good times,
