Getting stuttering lag in Multicam Monitor
Good afternoon:
I’ve crossed over from FCP 7 to PP CS6.
After I created a multicam sequence and attempted to edit in the Monitor window, I get a stuttering lag. When I stop and start again, it picks up nicely where I left off, but begins to lag and stutter soon after.
The footage is in .mov from when I originally off-loaded from 4 Canon HG20’s to use in FCP 7 as ProRes 422.
My system settings are:Model Name: iMac
Model Identifier: iMac11,3
Processor Name: Intel Core i5
Processor Speed: 2.8 GHz
Number Of Processors: 1
Total Number Of Cores: 4
L2 Cache (per core): 256 KB
L3 Cache: 8 MB
Memory: 8 GB
Processor Interconnect Speed: 4.8 GT/sI’m thinking I may “need a bigger boat”.
Hopefully, one of you can enlighten me.
If you need any more info, let me know.
Thanks for any help you can provide.

I think that model iMac came with a ATI graphics card? I think it was the ATI Radeon HD 5750 graphics with 1 GB of dedicated RAM. Is that right?
If so, that’s probably where the lag is occurring. CS5 onward preferred Nvidia graphics cards. CS6 made some allowances for ATI cards by trying to leverage the OpenCL API. Unfortunately, they made bigger strides with OpenCL and ATI cards in the Creative Cloud version of Premiere Pro.
There is a simple hack you can do to “make” CS6 recognize your ATI GPU so you can better harness the Mercury Playback Engine. Just be aware that you are modifying an aspect of the software so your mileage will vary. Those who’ve done it seem to report very few problems. Just do you homework (your modifying a text file that Premiere looks at upon launching to verify GPU specs).

Ryan: tried the hack but am not experiencing any noticible improvement. Maybe it’s time to upgrade. Thanks for your advice.

How is the performance without Multicam mode?

I’m a new user, so I’ve only used it as a multicam editor to see how it compares to FCP 7. Everything appears to be fine until I try to multicam with 4 cameras. Then: molasses. I also have a problem with tons of dropped frames when using FCP 7. I think I need to upgrade to something faster. If I may, what are your thoughts on “hackintoshes”?Thanks. Michael

Yes that definitely sounds like the performance peak of that Imac. You might try 16GB of ram but the CPU will limit you. I cant speak about question you reference since that is outside of Apple’s licensing. I can say that PC hardware has far better options right now especially with the X79 platform and or new Haswell platform. The X79 would be the best solution followed by Haswell if the budget is more limited. If Multicam work is your predominant workflow, make sure you look at 32GB of ram and a 760GTX or higher video card.

Thanks for the input. I guess with editing, more is gooderest.
