i think i just found a bug in PPro CS5. I've tested it on two PCs. Exporting an MPEG-2 through PPro CS5-Export or Media Encoder CS5 causes asynchronous Audio/Video - exactly 3 Frames the Video is before the Audio. I tested it with all MPEG-2-Export-Options, all kinds of Source-Material and all Export-Formats. The problem appears only with MPEG-2.
Maybe there's a problem with the MainConcept MPEG Exporter built in PPro CS5. The same procedures with PPro CS4 and Media Encoder CS4 work fine. There's one interesting exception. Changing the Audio-Settings in MPEG-2 Audio-Export-Configuration from MPEG to Dolby Digital, exports a video with asynchronous A/V of app. 0,5 Frames.
So i think it's a bug in the new built-in PPro MPEG-2 Exporter (MainConcept,CS5, 64 -Bit), focusing on the Audio-Export-Feature of an MPEG-Stream.
Anyone can reproduce this bug?
Where can i report such a bug to Adobe?
I've never had this problem and I export MPEG-2s all the time. The only time I've had any issue like this is when i made some change to MPE or something and I didn't then restart premiere pro afterwards. I'm not saying your not having an issue, but the mpeg-2s have been the most reliable for me so hopefully you can find the problem. Also check to see if you have any Anti virus software running at the same time. Can do crazy things.
Personally, the only time I would be using the antiquated MPEG2 export is for DVD, in which case I'd be exporting the audio as a separate WAV file, not a muxed MPEG. For all other purposes, I use the much better H.264 codec.
Is that not a suitable work flow for you as well?
I need special configurated MPEG2-Files for upstreaming to a satellite. Can't use H264. I tested exporting on a fresh, virgin system - same problem. This error is happening on all our workstations in our office. I don't know what this should be??
At our TV-Station we're outputting many Videos every day and they have to go right on satellite. We got no time to render an Ouptut and render again a MPEG2-File with another Software. Is there a solution to output right out of the Premiere Timeline?
