yes should be 1920 x 1080
The Premier files tended to fall to pieces and crash or hang when re-opened and the After Effects composits shredded at the slightest provocation.
Do you mean scene detection was on when you say fall to pieces? Can you elaborate.
Premier files with multiple sequences from other Premier projects tend to
hang when loading.
After Effects dynamic link files do not preview and have to be rendered.
This takes for ever and its quicker to render the media directly from AE
which kind of defeats the point.
I have just done a trial and the same problems are still there. Premier
warns about meta data inconsistencies. Replacing the files with new versions
solves that problem but the project still crashes when outputting. The
Premier file created then hangs when opening. The auto backup file does the
same. I can import other Premier projects and copy and paste the timeline
into one big timeline rather than using the sequences. That works but it
doesn't update which is what I really need.
For a long form piece like you're working on, you should use Dynamic Link to get a comp or bit into shape and then when you feel pretty good about it, render and replace the Dynamic Link with a clip. DL uses a lot of memory (which is why we recommend 64 bit OS and lots of memory), so it's good to keep that in mind when assembling a large project.
Premiere Pro 4.1 is a pretty good, stable product and we expect 4.2 to be better. WIth your system and understanding of the above, you should have no troubles.
Hope this helps,
