First spot for broadcast. Need some advice for output!
So, I’m doing my first spot for BROADCAST (woo hoo!) and the media distributor is asking for a specific type of MPEG-2 to upload to their facility. I’m creating it in AE 6, then I was thinking of bringing an uncompressed AVI into Vegas 6 to make the MPEG-2. Can I encode this with AE or Vegas, or do I need a more specialized application? Here are the specs:
Encoding – MPEG-2
Min – 10 Mb/s
Max – 25 Mb/s
Preferred – 25 Mb/sScanning – 480 60i (upper field first)
Pixel Aspect Ratio – 0.9
Aspect Ratio – 4×3
Chroma – Min – 4:2:0 (MP@ML) (720×480)
Chroma – Preferred – 4:2:2 (422P@ML) (720×512)GOP – All Allowed, IBBP preferred
Frames per second – 29.97 (NTSC)
Stream Type – Program Stream
Audio-MPEG-1, Layer 2 – 384kb/s Stereo
Audio-Dolby AC3 – NA
AVG Digital Audio Level – -17dBfs
AVG Analog Audio Level – +4dBm
Luminance Level Max – 100 IRE
Chroma Level Max – 120 IRE
Setup level – 7.5 IRE
Timecode – Non Dropped Frame
Also, how would I QC this type of file?
Thank you so much in advance. I’m very green when it comes to the broadcast world. Been working with web content so long, just need a little guidance,

HI,
if all your specs are possible in Vegas – use it.
I-m sure your Broadcaster will be able to check your
file. (isn-t he able to convert your AVI?)For our output we use the canopus stuff https://www.canopus.com/products/ProCoderSW/index.php
also tmpeg works well – maybe you can find a 30days trial.
One or two things more:
I highly recomend to watch your work on a broadcast monitor
(a normal television can do this work not perfekt but OK too.)
pay attention to Titel and action safe areas – and
the flicker problem of fine horizontal lines.many luck!

That’s a standard MPEG2 stream save for the -17dB audio level. Just output your file as an uncompressed stream for AE and use Vegas to compress it to an MPEG2 file. make certain to have bars & tone for at least 30 seconds, a readable slate with all of the production info including your contact info and a countdown with a 2-pop in a single video file so that the loader can get everything he needs. That way, he can balance audio to their needs with your tone, caculate accurate colors from your bars, get all of the client and spot title information and have a countdown so that he can do an accurate capture into their Odetics or media pool player.
The specifics are all there. Even if you adjust something slightly different from what they expect, and unless thy are real hardasses, you’ll be right on target for an acceptable delivery.
If you have access to it, take your raw file to a dub house and how them put it onto an acceptible tape format. DVDs are acceptable, but not preferred by most broadcasters.

Thanks for the tips!
Could someone please list the info that typically goes onto a slate for a television commercial? I want to make sure I don’t look like a punk when I send my spot to the media distributor.
Thanks again,

Typically the slate includes:
Client Name (Brand Name)
ISCI Code (Industry Standard Coding Identification)
Spot Name
Running Time
Date, usually the completion date for that particular spot or revision
Copyright Info for Client, i.e.
