Newbie seeks help rendering for TV

Hello everyone, I've put together a 3d (640x480) 15sec animated commercial. Everything was created within the PC and all I have is my PC and CD burner. The company states that they'd prefer the submission to be Digital Video Format (DV). My question is two-fold, based on what I've described above, is it possible for me to submit the piece in DV format and if so, how would I go about doing so? Do I just render the piece, burn it onto a CD and mail it out? Thanks in advance for any assistance.

That should work fine. You an fit about 3 minutes of DV on a standard CD-R, so your 15 seconds should fit with room to spare. Render to AVI and choose the standard DV template (either NTSC or PAL as is appropriate for your area). This will create a .avi file on your hard drive. Burn this to CD and you're all set.

Hi DarkSkills,

One very important thing if your product is going to be aired on TV: your video levels. Your computer will generate images that go from 0,0,0 RGB to 255,255,255 RGB, corresponding to 0 IRE to 110 IRE on a vectorscope. In North America, tv broadcasters require IRE levels from 7.5 to 100, 7.5 IRE being the blackest black and 100 IRE being the whitest white.
When you do your final rendering, make shure you correct your levels.

Videogram, is what you're referring to something that can be taken care of by applying the 'Clamp' or does something else need to be done?

What do you mean by "the clamp"?

I'm sorry, I meant going into the 'Video Output FX', selecting 'Broadcast Colors' and then applying the 'Clamp' preset.

I don't use this method. Say a pixel has a value of 0,0,0. His neibour pixel has a value of 14,14,14. These 2 pixels are different shades of black. If you "clamp", these 2 pixels will be identical (16,16,16). Therefore, clamping will loose the details in blacks and whites (same thinking for whites over 235,235,235).
I prefer to use the color corrector and adjust the gain and offset while monitoring the results on the scopes.
Hope this helps.

Thank you for your assistance:) I believe I understand now, but the color correction you speak of, is this a tool within Vegas?

Color corrector is one of several new video FX filters in version 4 you can use to "correct" hue and luminance. You could still make adjustments in version 3, but the process was somewhat more difficult and less precise.

Perhaps you'll find the tutorials I wrote useful:
