How to deliver spots to stations digitally

[T. Payton]

[Frank Nolan] “Take a DVCPro50 timeline, compress it to M-peg2 for DVD then lay that to a Digibeta or BetaSP, which will then more than likely be compressed to m-peg2 again for transmission? That will surely look horrible.”

I actually think most of the MPEG2 artifacts will be reduced greatly becuase of the downconversion that a DVD player would be doing. You going from a MPEG 2, 720×480 Anamorphic, to the effective letterboxed SD resolution of about 640×358 that will be layed down to beta. This size reduction in combination of the “softening” with the analog component connections from the DVD player should make the Beta dub look quite nice and free of artifacts.

Although MPEG2 is a lossy process and looks horrible on paper (4:2:0, ouch!) in application and when treated properly can look very good.

I am not sure if you and I are reading the same post but there was no mention of anamorphic or needing to down convert. DVCPro50 is SD with 720×480 lines. So it is very close to digibeta which is 720×486.

Note to self. Don’t reply to CreativeCow post when you’re home sick surfing the net and should be in bed.

My bad. In that case you are much better off going to a post house with FCP capability.
