I have projects that were created in PremierPro 1.5
When I try to open them in PremierePro CS4 (tryout version) I see the assets, but nothing is shown on the time line. I can not even drag any of the assets to the time line. If I double click on the asset, it will play.
What am I doing wrong?
Is this a limitation for the "tryout version"?
Wild guess, that has tripped many: Double click on the sequence in the project panel.
If you have the trial version, you will have real problems with anything MPEG, as nothing MPEG is supported. Other than that limitation, you should be good to go, when you follow Harm's advice.
Now, there can be other "tripping points," like 3rd party Transitions/Effects, Matrox Captures and the like.
Good luck, and let us know if your PrPro 1.5 has anything MPEG in it - that will not work.
