Faulty Premier 8
I purchased Premier 8 last May and use it for home projects until last week when scrubbing the timeline it was lagging badly and I could drag down transitions. A techo friend de installed and re installed however the faults remained. He then download premier 10 trial and everything works perfectly. is there an upgrade for P8 or have i waisted my money. GD
I'm not sure why you purchased a two-year-old version of the program -- but the upgrade for version 8 IS version 10. That's why it's called version 10.
That said, the performance of the program is a combination of your source video, project settings and your computer's hardware and operating system. Version 10 certainly does perform much more efficiently than version 8, but the program itself isn't the only factor to consider.
