BitRate Too High Error at DVinfo.net

Pete Cofrancesco · June 23rd, 2009, 12:12 PM

I encoded a 3 minute movie from Premiere using the Media Encoder. I set it to DVD MPEG2 with the highest bitrate 9. After authoring the menu in Encore, I tried to burn but got the error "Bitrate too high". I went back and re-encoded at a slightly lower rate which fixed it but I'd like to know why would the media encoder allow me to select a bitrate that's too high?

When I encoded with the audio separate form video I got this error when I went to build in Encore http://i39.tinypic.com/nmeu8o.gif
I went back again and re-encoded with Multiplexing selected and it got rid of the error. Can anyone tell me why?

There are a lot of things features I like over Apple but I'm getting the impression that the encoding and authoring part is very buggy.

The functional ceiling data rate for DVDs is really 8Mbps for constant bit rate encoding. I don't know why 9 is allowed when 8 is the practical maximum. Perhaps it's to handle spikes in variable bit rate encoding, but that's just a guess.
