I was told I need to add 20 seconds of the "color bars" with a 0 DB audio tone at the beginning of my video, for cable tv broadcast. Anyone have any idea where to get this? Would it be the NTSC color bars that i see in Sony Vegas Video? I'm not sure where to get the audio tone... This would be american cable tv broadcast.

From what little I understand it might not be as simple as "sticking in a graphic" of color bars.

The color bars are intended for calibration of colors from different video sources. The colors are generated by the program or video device and everything else that follows will "match" those bars.

I think that if you use some external editor to export final video and it has a color bar generator this should give you what you need.

I am just guessing about this. I hope someone with more experience can give more help.

Thanks- yea this company didn't really give me much info. Seems like they should be the ones to have to take care of this...

Sadly, this involves a contest that I entered but didn't even get 1st place prize on... but by entering I gave away all rights to the video. And since my video is better than the one that won (with the most text votes), it's mine they'll probably be airing... Live and learn, I suppose.

Most of the time they just want a leader so they have something to scroll through. The bars give the person something to look at while queuing it up.

Ask if they need correct colors.

Every decent video editor is able to create that leader. If you don't own one, ask a friend who does to render those 20 sec so you can paste them in front of your material.

The leader is there for a purpose: if the material is on tape, the machine needs some seconds to adjust. And by looking at the colour bars every technician can immediately judge if there were seriously wrong colours on that tape.
