Activity Forums Compression Techniques Episode and DGFastchannel spot distribution

  • Episode and DGFastchannel spot distribution

    Posted by Craig Seeman on February 26, 2008 at 4:34 pm

    There have been various threads here about meeting DGFastchannel spec so I thought I’d post as a new thread to make it easy for people to spot.

    As a Mac users I use Episode when I distribute local cable spots via DGFastchannel. Recently DG has been requesting 720×512 encodes.

    The folks at Telestream created a patch and gave me a “beta” to test with DG. The patch works. It’s not included yet so you have to ask them for it.

    Some folks on the forum have had Nielsen Sigma encoded material as source and of course want to keep the Sigma watermark (used for tracking on air use).

    For those who are using (or would like to use) the DGFastchannel patch. If your 720×486 source is Sigma encoded, don’t use the resize filter (crop). The resultant encode will keep the Sigma encoding and will be 720×512. This has been tested and passed DGFastchannel.

    We ftp dozens of spots each month via dgDropBox at 720X480.

    DG has not asked us to change to 720X512.

    Why did they ask you to change?

    Are you adding 16 line of black to the top and 16 lines of black to the bottom of your images?

    DG has “grandfathered” in older customers. Actually I’m one of those also. They are asking new customers to use 720×512 though.

    16 lines at the top and bottom does not work for DG. They need all the lines on the top. I beta tested a patch that Telestream created and is now part of Episode 4.4.2. The reason for the lines on top is, amongst other things, to accommodate Nielsen Sigma Encoding (tracks use on the air).

    If one has Sigma encoded the spot you can now click a button in Episode and the black will be added to the top. If one does not use Sigma encoding one can click the button and meet DG’s 720×512 spec.

    If you’re not using Sigma encoding and DG still accepts your 720×480 encodes than no need to worry. Keep going as you have before.
