Re: Broadcast files for Digital Delivery

Todd,

Do you have any compression software to take your uncompressed spots and convert them to mpeg2? We use Sorenson Squeeze here and haven't had problems (once we nailed exactly what the stations wanted--good luck with that).

If you have Squeeze, or can set up a custom compression using Adobe Media Encoder or Premiere, here are my settings:

Stream Type: Program Stream

Audio:
MPEG1 Layer Audio
384Kbps
Sample Size 16, Sample Rate 48000
Stereo

Video: MPEG2
1-pass CBR (we've had problems with VBR playing nice with the stations here)
Date Rate: 10000Kbps
Format: NTSC
Frame Size: 720x480 (we mixdown to DV50 and export 720x480 from our editor)
Frame Rate: 29.97
PAR: 4:3
Field Encoding: Bottom Field First
GOP Structure: I Frames: 15, P Frames: 3, AutoGOP: None, Close GOP unchecked
Advanced MPEG Video Settings: ProfileID: Main, LevelID: Main, ChromaID: 4:2:0 (we've have trouble with 4:2:2)


A :30 spot is typically about 50MB (includes :08 slate + :02 black) and quality looks fine on air.
