Premiere was being glitchy and running really slowly, and I hoped the update would help...
Well, after I updated to the current version, everything in my project was all screwy: my clips had been re-trimmed to the wrong points, and my overlays were coming in at the wrong time and my transitions were all sorts of wrong (wipes where dissolves were used, the transition duration blown to Hades). 😡👺
Normally, I'd shrug and say I'd just reset all those things, but as the timing was very precise - down to 100ths of seconds - this would take me WEEKS and I don't have the time or the patience for that nonsense.
How can I fix this without wanting to set myself on fire?
It is up to everyone to send a feature request for Adobe to scrap the Mercury Playback Engine and rewrite Premiere Pro CC from the ground up. There are so many bugs that have not been fixed in over two years and new ones being introduced in every new release.
