May 21, 2007 at 3:26 pmThe best thing to do is to call them directly and verify that the festival does indeed have a digi betacam vtr for playback.
Inquire if they will feed the projector via SDI , analog component or even worst NTSC composite.
Bob is dead on with his advice assuming the festival does have a digi beta vtr. If not there is some major confusion regarding what they are specifiying versus what you can delivery to them.
So when in doubt call them and try to get it in writing as to what specific vtr they will be using and how they will output it to the projector.

May 21, 2007 at 11:48 pmThanks again for your detailed information and responses, Bob.
Yes, Tony, the best thing would be for me to have asked the festival in time what machines they are using, etc… But, the festival begins on Friday (MountainFilm in Telluride), and I had to FedEx them the tape today.
I did some more color correction yesterday, and then outputed to an UVW-1800 BetaSP deck taht I rented (at an IRE of 7.5), and sent it off.
I feel pretty confident that their setting specs were wrong.
For one thing, I sent them a priliminary BetaSP tape for them to test (before I sent the final), and I set the BetaSP audio tone to “0 db”, and they said that the audio was o.k. (In their specs, they asked for audio tone at -20 db, so I am almost sure they are refering to digitial specs, and as Bob mentioned, probably a DigiBeta deck.
I appreciate everyone’s thoughts and feedback.
