AVCHD Premiere Pro CS5.5
I’m working with AVCHD files off Panasonic GH1’s and HMC150’s mainly.
I am usually only using one layer of video, occasionally two, and very minimal effects (dip to black, cross dissolve, RGB curves)
even without effects the source files don’t scrub very well, they playback fine, meaning I can start and let it play and it never hickups. but if I try to scrub around it take awhile for it to update.
my desktop setup:
AMD Phenom II X6 2.8ghz (six cores)
8GB DDR3 Ram
1TB 7200RPM System Drive – SATA
3x1TB 7200RPM RAID for Media Drive – SATA
Nvidia GTX 470 GPUwhat is bottle-necking this? I though maybe it was the ram so I was going to upgrade to 16GB, but I canceled the order since, I left task manager permanence monitor open while editing and the whole system was only using around 3GB ram.
Thanks,

My bet is that it’s the video card. I have that one, I think, and I find that scrubbing is a bit like you describe. Seems to need to load into RAM. Once in RAM (after the initial few seconds) it seems to scrub fine. I’m exploring stepping up to the 4000 series from nVidia. Maybe someone else on the board could comment if that seems like overkill.
You didn’t mention your monitor but you might check to see that it’s refresh rate is fast. I know that some monitors (especially a few years old) don’t have a great refresh rate. And how is your monitor connected? DVI or HDMI I assume?

My monitors is a 1080p monitor connected via DVI I believe it’s a 2ms repsonse time @ 60hz.
If your referring to the Nvidia quadro 4000s I think they have less cuda cores than the gtx 470 (about half as much)
Thanks,

Ok, so at least the basics are out of the way. It’s not the monitor refresh or something like that.
As to the GTX 470, it appears on their ‘previous generation’ page, however the 450 appears on the still produced list. (why?) so I believe it’s been at end of product life. It does appear that it has more cores, but I’m unclear as to whether the engine is specialized for gaming or video rendering. I assume it’s fine though with that many cores.

CS6 seams to have fixed the issues for me
Thanks,

Yeah, Adobe had screwed up the scrubbing function in CS5.5. Scrubbing was great for DSLR footage and AVCHD footage in CS5. Then low and behold in CS5.5 it sucked. I’ve tried a demo of CS6 and it does seem to have fixed the issue. My fear, with Adobe products, is that once I purchase and start on a real project there will be a host of new issues that will hobble my workflow. It always seems 1 step forward and 2 steps back with Adobe Premiere.

My thoughts exactly, the scrubbing issue was a bug not a feature change, therefore it should have been fixed in a free update not included with a full upgrade to force us to upgrade. hence why I opened a case against Adobe for selling and mis-advertising defective products.
Thanks,
Jason
