Excuse me, but I'm a newbie in software editing and I cannot understand which of the limitations is preventing me from exporting a video of good quality: is it due to missing mpeg support?
However, I have the same problem with a wmv file.
For the trial versions, stick to using only DV media that you shot yourself using a MiniDV camera. You should have better luck testing.
Premier Elements does a lot of the thinking for you. Which can be
good, can be bad.
Premiere expects you to do the thinking. AME gives you a lot of flexibility but with that flexibility comes opportunities for options not to be properly selected.
If your sequence in Premiere pro has format settings that match your input material, and you make correct settings in AME, you can get a very high quality output. Problems creep in when the settings do not match.
In CS5, there is an option in which you can drop one of your captured clips on a icon and Premiere will open up a new sequence that has exactly those settings.
High bit rate is useless if your pixel aspect ratio, field order, resolution, image size, frame rate, etc, etc, etc are not set correctly.
