  Ultra Scope/Black level adjustment

  Posted by Jay Agoglia on June 2, 2011 at 5:18 pm

  Hi All!

  asking the professionals what I should use to:

  Monitor sdi (SD&HD) video signals from VTRs (Digi beta, HD Cam, HD Cam SR)to analyse and display black/white/color video levels to determine legal/illegal video levels?

  also what is the best way to adjust these levels to proper specs when proceeding to capture/encode/digitize?

  I was looking at the black magic ultra scope so that I may patch in any video signal and see multiple video displays. But I believe I can not adjust the levels in the ultra scope software. Is this correct?

  Do I adjust the signal from the decks or with a separate hard ware/ software unit?

  we commonly receive many commercial spots by digi beta tapes and FTP (playing out a vela card sd&hd) and need to input this method of monitoring video levels and hopefully adjusting levels as well. We use clip-mail and pipeline mostly to encode and digitize.

  any help of thoughts would be greatly appreciated.

  thank you !!

  the Ultrascope is a scope. You don’t fix things with a scope.
  You adjust your levels with a proc amp, or TBC adjustments on your VTR. No matter what anyone tells you, you are never going to learn how to adjust levels on a user forum like this. You need to be trained. You can go to https://www.tek.com, and look up to see if they have any training material on reading a waveform monitor.

  Thanks Bob!

  I will check the link and start learning about the controls and adjustable parameters on our VTRs.

  thanks again,
