CS6: First TV Spot, Want to Get Encode Settings Right

[tommygdawg]

Hey all,

Some of you may have seen me posting in the audio section about my first TV Spot gig that I'm doing. I'm getting the audio under control now, and really what I want to do is make sure I'm getting my encoding settings right. I'll be encoding using MPEG-2. My question is, how do I make sure that Media Encoder CS6 is using an IBBP Closed Long Gop? Also, does anyone know what it means in the notes section by "MP@HL" and "HP@HL"? Here's a screenshot of the requirements:

Thanks!

Main Profile @ High Level
High Profile @ High level

These are just parameters that allow specific settings in the export process.

The default M=3 and N=15 will provide the IBBP structure. Change Closed GOP to 1.

The issue may be with audio. It appears PP will only mux Dolby Digital. If you want MPEG2 audio, it'll have to come out as a separate file and muxed outside of PP.

Thanks! Very helpful So, it's saying I can use either main profile OR high profile? Doesn't matter? Also, as an aside...do you have an idea why premiere labels the I frames and P frames as M frames and N frames? This confused me for the longest time until I realized they were synonymous.

In regards to audio, in the Media Encoder under the "Audio" tab I can choose either "Dolby Digital" or "MPEG". So I chose MPEG, and then under "Basic Audio Settings" I chose "MPEG-1 Layer II Audio". Premiere multiplexes the audio into the video file, so I think this should be correct. Or am I reading something wrong here?

--Edit--
Also, just to double check. I've been shooting and editing in 24p (23.976). I assume since they want 29.97, I should simply tell Media Encoder to output at 29.97, 1080i (upper field first) file from my 23.976 timeline?

The Profile simply allows various options. For example, Simple Profile won't allow HD resolutions.

I don't know why frames are listed as M and N, but it's not just PP. I see it often when MPEG is discussed.

I goofed on the audio muxing. You did it right.

In my tests, PP did not do a very good job exporting out 24p as 30i. You may want to contact the station and see if they'll take a 24p export, as often hardware can add the pulldown better than PP can.
