  Generating a master for TV

  Posted by Buck Wyckoff on July 11, 2007 at 4:23 pm

  I’m outputting a 30 second commercial spot for a client that will air on TV shortly. Most of what I do is litigation animation and video production.

  I’m wanting to learn how to do things right.

  I think I need a slate at the beginning that states client, production, length, date produced…etc.

  Also, I’ve seen color bars and a tone for 30 seconds or so that I guess engineers use to evaluate the tape quality.

  My client supplied graphics overlays with letterbox type margins. The letterboxing is pure white, with pure black lines separating the action inside the letterbox. The red of the text and logos are not purely saturated and are fairly video safe (they look reasonable on my NTSC monitor).

  But I’ve heard of such things as 7.5 IRE black etc… Is pure white or black in this composition a problem?

  I put all of this together in the compositor Cumbustion, output sequential targas and compiled an uncompressed video clip in Velocity that I will be putting on my BetaSP deck.

  I was also wondering about whether a 30 second commercial had a head and tail, or really was exactly 30 seconds on tape?

  If someone could educate me on the issues above, I’d greatly appreciate it.

  PS: I can pipe my video from Velocity into DV Rack and see it on the waveform mmonitor/vector scope, thought I don’t know what to look for.

  Thanks a bunch,

  make ure you monitor with a waveform monitor and vectorscope. Dont go drivin’ blind. You do have to adhere to 7.5 ire for black and 100 for white. As far as the red, as long a it isn’t outside the corcle on the scope, your ok.
  Lay down a minute of bars and tone, 8 seconds of slate, 2 seconds of black and start the spot at 1:00:00:00.
  It’s duration should be 29:20.

  Thanks a bunch.
  I had already sent them out.
  They are not according-to-hoyle, but some stations are more forgiving.

  One got axed (from Tyler, Texas) and I made a new one according to your specs.

  Thanks again.

  yeah, many networks have very strict bilaws. Wouldnt expect it in Tyler TX but whateva. They don’t mind sending you a spec sheet if you ask.
