Downgrading the ADOBE PREMIERE project manually:
1
Change the project extension from .prproj to .zip
2
Unzip the resulting file
the output should be an XML file of impressive size
3
Open XML in a text editor
4
looking for a line of code like:
<Project ObjectID="1" ClassID="62ad66dd-0dcd-42da-a660-6d8fbde94876" Version="41">
5
Change the version number to a lower version
for example Version="41" change to Version="25"
(opens in the 20th premiere and higher)
(opens in the 20th premiere and higher)
6
Save and change the file extension to .prproj
7
Open in the required version of ADOBE PREMIERE and resave the project
it becomes an adequate size and you can work in it. It can take a long time to open a heavy project, patience.
good luck to everyone
