Problems when encoding MPEG 2 with no B-Frames

$

Hello,

 

I am running into a strange artifact while using AME to encode to MPEG2.  It's kind of a long story and lots and lots of troubleshooting with different encoders... but... here's the upshot and I can explain more if it helps you.

 

The program I am using for playback is requiring a file with gop structure IPPPP.. -- NO B-Frames.  I believe the way to do this is M Frames = 1.  I have N Frames = 15 which is essentially an I-frame every 15 frames and only P frames in between.  Do you concur - do I understand this correctly?

 

Here is the problem, when changing M Frames =1 I get poor blockly quality only on the first 2 frames of the encode.  The rest of the file looks great and plays back great.  Other encoders I have tried with same or similar settings do no have this problem - however, I like the color output of AME better, so I am trying to find a way to use it as my primary encoder.

 

Here are my settings:

Dropbox - MPG2 1080p30 25000 (No B Frames).epr

 

Looking forward to a response... thanks.

PS - I first tried chat support.  Waited almost 20 minutes for first response, then constant waits between.  This person was ill-equipped to help and could only say, "ask in the forum".  Wasted an hour of my time.  So - hopefully someone from Adobe will respond to this and try to either help or confirm there is nothing I can do.
