Bars and Tone for Broadcast at DVinfo.net

Maurice Ali · July 14th, 2005, 02:21 PM

I have a half hour program that has passed (certification - Canada) and screening by one of the networks here. All that remains is to convert to Betacam or Digital Betacam while meeting technical standards.

Question.....

I have a choice of Betcam SP or Digital Betacam which is better for converting a mini DV (DVCAM) recording?

Bars: Does the color bars on my PD170 meet broadcast standards - NTSC (or does it really matter in the real world)? Also - I have to provide segments of "coherent black", is this just recording with the lens cap and and protected from any form of light, or do I have to get it from the editor I am using?

Tone:

The PD170 does not seem to have tone, am I correct here? Also, my AVID editor has a tone producer and is set at 1000hz with a db level of -14 and reproduced on one channel. But if I go with digital betacam, should the db be set to -20? Should I go with the one channel default setting on tone or two channels?

This is my first time putting a show on the air.....anything else I should know at this stage before I submit the tape?

afaik no bars off prosumer camera's are 'legal' (talking pal).

ask the station for their tape 'set-up'. it varies quite a lot from 1min t&b, through to quite complex id's, etc.,

Colour bars from a PD150/170 are quite "legal" - that's the whole point of having them...
Same goes for the FX1/Z1 - even an XL2 (XM2 for that matter)
