When I import a short AVCHD or MPG (~ 1 min., 100 mb) into Premiere Pro CS6 or After Effects CS6, it plays great. When I import the same file into Photoshop CS6 on the same computer, it's jerky, even with sound off, frame skipping enabled, cached, and no other applications running.
I'd never use Photoshop to edit my own videos, but I have to teach this stuff, so I need to know what's happening. Any ideas?
System is a Core i7 with 8 gb RAM, 1.5 gb nVidia GeForce, Win 7 x64 and DirectX 11. All drivers ruthlessly updated.
I guess you could bring the Task Manager and keep ian eye on CPU, and memory usage while playing that video in Photoshop. Or better still, go ask in the Premiere Pro forum because they are gpoing to have way more expertise than most Photoshop users, (unless Bill Hunt happens across this thread). You might also ask in the Premiere Pro Hardware forum.
Curt: the videos played fine in Bridge. I don't know why codecs would be an issue; they're installed onto the system itself, so if Premiere Pro uses a codec, shouldn't Photoshop be able to use it? And these are AVCHD from my Canon Vixia, MPG from my iPad and AVI from a Flip. Nothing offbeat.
Trevor: Task Manager and Resource Monitor show that PS and Dynamic Link Media server are using the most CPU and memory (when playing the vids). Only about 50% of the CPU was in use and about 3.5 of the 8 gb memory was in use, even though I manually boosted available memory in PS to 6 gb. So the machine isn't even close to being maxed out.
I edit videos on this machine often, and have never seen performance as bad as what happened in Photoshop. Now I'm on my ASUS laptop. Tomorrow afternoon, I'll test on my workstation, which has the same amount of RAM, faster hard drives, faster video card, and slower CPU.
