Re: [Avid-L2] Re: AMA transcode straight to on-line workflow

John,

Something to keep in mind when you're cutting with pulldown added material
sources. If the source material is an edited piece, try not to cut on cuts.
In other words, if you have something like this in 23.98:

A B C D A B C D

which looks like this with pulldown:

AA BB BC CD DD AA BB BC CD DD

If there is a cut in the source on a C or D frame, the pulldown added
version of that could have the BC or CD frame composed of a field from
before the cut and a field from after the cut. Be aware that most video
output hardware (and the source/record monitors in software) won't show you
both fields at once. So you can't see it unless you step through field by
field. The solution here (to avoid field flashes) is just to not cut on any
frame that is also a cut in the source.

I hope that makes sense. More than likely you're not using 23.98 source
material that has already been edited, so you wouldn't have to worry about
this.
