[Daniel Low] “Not the right format to choose, like the name implies, suitable for Animation, not video. Oddly enough though, PhotoJPEG would be a much better choice.”
There really is no visual difference between the 2 at 100%, and there is a size hit on Animation, but I find the codec to be better supported on the Windows side.

Agreeed, but PhotoJPEG is MUCH better supported on windows. MPEG Streamclip will make a PhotoJPEG .AVI that works much better than a QT file on Windows inflicted boxes. For example it works with apps that don’t accept .movs.

[Todd Terry] “believe my editor tried exporting as a Quicktime Animation, but still had very poor results.”
Todd,
The poor quality results might be due to a QuickTime player setting and not due to the file.
Try this:
With the file open in QuickTime Player…
Choose “Show Movie Properties” from the Window menu items. This will open the Properties dialog box.
Select the Video Track.
Select the Visual Settings tab
Make sure the High Quality check box option is checked.You can save the file with this new option set and it will always open that way. The interesting thing is that this only changes the way the QuickTime player displays it. If you bring the file into After Effect for instance it will look exactly the same no matter how this option is set and saved in the file.
Hope this helps.

Hi Todd,
Haven’t talked in a while…
I’ve delivered MPEG2 without much fuss…though I’m delivering HD.
If you deliver a high bitrate file, it will simply go through another transcode to get the file into the station’s (or network’s) server. In some cases with local stations, their dog’s breakfast of automation ends up looking like a bazaar and they have to transcode to cue properly…it just depends.
It shouldn’t be all that difficult really…Comcast can’t give you a data rate? Typically it’s a framesize, usually a transport stream file, they’ll have a peak data rate, and some scary language about any out-of-engineering-spec submissions…and you’re done.
Television is easy…have you tried to deliver spots for exhibition in a movie theater? I’ve had tax returns that were shorter than the documents I had to follow from those guys…yeesh.

[Daniel Low] “Stations don’t want to have to re-encode, they want something that works on their systems.”
Indeed…and QuickTime’s archaic index file structure makes it a pretty rare format in broadcast server territory. Playout’s future is likely Flash, but is principally MPEG and MXF these days.

That is most certainly not the future in the UK!

Well…
I’ve done some work with some playout server manufacturers…so I have some insight into where at least one is heading.
That interactive layer on Flash becomes a revenue source that MPEG or MXF wrapped material doesn’t have.
While Flash isn’t big yet…anywhere, I think it’s inevitable that it will take over eventually.

Interesting, I’d like to learn more about that.
[Tim Kolb] “While Flash isn’t big yet…anywhere”
Well, except on the interweb….. 😉

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
StereoVideo: MPEG2
1-pass CBR (we’ve had problems with VBR playing nice with the stations here)
Date Rate: 10000Kbps
Format: NTSC
Frame Size: 720×480 (we mixdown to DV50 and export 720×480 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.
