DG Fast Channel Questions…
I’d like to pose a few questions about DG Fast Channel Delivery, for those with experience with DG delivery.
1. Is there any kind of hard ware unit that will allow me to view on a NTSC interlaced monitor and WFM/VTS the encoded file I create for DG? VLC is not getting the job done, we can’t accurately judge things until they hit the air, and DG QC is inconsistent we have found. We are using the template in Episode.
2. What is the consensus on black levels? I have heard several schools of thought. TV stations broadcasting ATSC still seem to require 7.5 setup. Internally we work with 0 IRE black levels in color correction. Somehow… our 0 IRE is getting amp’d up to 7.5 by the time the TV affiliates get the spot, and DG reports our 0 blacks as 7.5 on their end. Is Episode adding the setup? Is DG?
To expand on this, I did a test with DG… three files, one with our 0 IRE blacks, one with -7.5 or crushed blacks, and a third with 7.5 blacks. DG reads 7.5 blacks on the first two tests, and on the third, which I ProcAmp’d up to 7.5, they rejected it with improper black levels. Looking at the uncompressed file on a wfm… blacks on this third test were ~15 IRE. So, what is happening?
Any feedback is really appreciated.
