Transcode settings for MPG
I have edited an AVI file in Prem Pro. Want to expoert it out as an MPG. Not sure what transcode setting would be good with reference to the following: 1. The AVI file properties in the timeline window show “Average Data Rate=3.61 MBps”. Same file, if I right click on it in explorer and check properties, shows “Bit Rate = 1536 kbps”. Those two numbers and units are different and leave me wondering about the ACTUAL bit rate of the file. If I could find that out, I would use that value in Mainconcept trancode setting to export to MPG. I assume, using lower value than the original AVI would result in reduced quality than the original; and higher value will not improve the quality of the original but make the file fatter unnecessarily. So how do I determine the real bit rate of the original AVI file?

3.6 MBps is the combined (audio+video) bitrate for Digital Video. Windows Explorer only display the audio bitrate which is 1536 Kbps for 48 Hz PCM audio.
Regarding cpmpression settings for the Adobe Media Encoder…what is your target? DVD…local playback…web???

Thanks for the info about the bitrate shown in PP versus win explorer. Very useful. Yes the file will end up on a DVD eventually with a bunch of other files totally about 3 hrs on a DVD9. [It would be for my personal/private use, so standardization is not an issue.] I used a bitrate calculator on Google to determine that 3 hrs video, transcoded at around 5500 bitrate in Adobe Media Encoder, would fit on a DVD9. That would be pretty decent uqality video. In the past I had actually put 3hrs+ video on a single layer DVD, by transcoding it at about 2000. True, it wasn’t very good video, but it wasn’t worse than the source material.
