is it possible to take transistion from 8 to put in 11
or is it a site in which I can find transitions
These are for Premiere Pro, but many will work for Premiere Elements. You will have to sort through them to see if they have what you want and if it is supported by Premiere Elements:
Another option would be to use the transition in an earlier version and output just that portion of the clip and then import it into a project in the new version. You won't be able to adjust the transition once imported, since it will be a single video clip, but that may work for you.
Beyond Premiere Elements 8.0/8.0.1, Premiere Elements does not support GPU transitions or effects. Details below.
Your description fits the Premiere Elements 8.0/8.0.1 video transition name "Sphere" found in 8.0/8.0.1 under
which includes "Sphere". The GPU Transitions and Effects were removed from Premiere Elements 9.0/9.0.1 and later.
So, I see no way of getting that GPU transition from 8.0/8.0.1 to a later version.
If you do a Google Search, there are numerous places to find video transitions. You have already given a lead for that.
Many, but not all, of the Premiere Pro offerings work in Premiere Elements. And, surely Premiere Element does not have the GPU transitions and effects support that you find in Premiere Pro.
So, please look for the trial version of the transition before purchase and determine if GPU transition or not and if alternative non GPU transition would give you the transition effect that you want.
Please let us know the outcome as your schedule permits.
