Thanks for the input Michael.
Well I had Compressor presets to give me some perspective in the beginning, so I looked around and thought 8.1 would still be fine.
(there are people on the net who say 9.8 is pushing it..!)
Compressor 3.5.3 “DVD 90 minutes at best quality” gives me a maximum bitrate of 7.7 and for Audio 192kbps (ac3)
My audio was exactly that, so I thought it would be “safe” to say the least.
What would you recommend for avg & max video bitrate & audio bitrate to stay on the safe side?
