Loss of Quality on Exporting from Premiere Pro 2

[Jc Of naz]

Thanks again for you assistance. We are just in the middle of doing research on the Canopus ProCoder. Sorry to ask another question that may seem dumb but here goes anyway… We are playing around with the settings in the Media Encoder and we set the profile to High and the level to High Level, then the bit rate allowed us to set it to as high as 100Mb/s. We set the rates to 25 Mb/s for Min., Target, and Max and rendered out a piece and it looked great.(compared to the previously mentioned problem) I haven’t uplinked anything to the distribution center yet as we just found this when you posted. My question I guess is: Is this something that is acceptable for broadcast or am I barking up the wrong tree? Compression has always been a “pressing” issue for us. There seems to be an OVERWHELMING amount of choices and one thing being off can screw things up royally. Thanks for your help yet again.

Yeah…that’s the ticket.

I recently had my workstation go down and I only have CS3 on my laptop and wasn’t sure if Adobe Media Encoder went above main level in v2…

Your barking up a very good tree. Go with it.

Maybe clueless in Canada – but you said you are exporting 720×480, but the spec you provided calls for 640×480?? Is the distribution system re-scaling the already compressed output?

[George Socka] “but the spec you provided calls for 640×480??”

I don’t see where this is quoted…there are times when 720 is not mentioned but since the “scanning” spec is 480 and the pixel aspect is .9, that would imply 720 pixels wide for a 4:3 frame aspect.

missed the PAR .09

Harm,

He is creating mpeg for a server and not for DVD so the high bitrate is not inappropriate. The 8 Mb/s that you suggest is way too low for his purposes. I do agree that CBR should be tried. A Target and Max bitrate that are the same value is pretty useless.
