Pro Res would be better than DVCProHD. I would suggest that.

The partial frame data and referencing of complete frames with long GOP also requires more data caching in ram. Complete frames can be segmented in ram and cached much easier based on the amount of system ram available. This is why the anomalies occur on partial frame codecs and not on full frame codecs but are not consistent as to when they occur.

Thunderbolt is fast enough for the SSD drive. I would suggest getting a big enough SSD to handle the cache and media files if you do that though.

What happens if you select Mjpeg instead of Pro Res? What codec do you capture with MC?

Keep in mind 8GB of ram is not enough for Quad core CPU and AE. The memory management alone can cause random issues when data has to constantly re-cache to complete frame data on ram preview or export. I would suggest you get 16GB soon which will also help your performance with such complex comps. Comp complexity is one of the major factors to the dynamic amount of ram you require per frame. AE’s caching models though will only cache based on the amount of ram available that is not in use by the OS or graphics. This will lead to frame buffer corruption at times when the compositing of frame data cannot process all of the layers into that frame correctly with the amount of ram available. Also remember the player being used to decode the media also require ram to do so. This is often outside of the ram the AE render engine/player requires.

Potentially yes but likely not the ideal choice since the monitor will have to maintain the data stream increasing latency. Can you not chain off the storage?

Yes but that wont be a large improvement over the 650GTX. I would suggest a 760GTX 4GB card if you really want a major improvement. You can also add the 650GTX to the supported list now and see what the performance is like.

Any of the Geforce 700 series cards such as the 760GTX 4GB will work. Those just have to be added to AE’s Ray Tracer supported list.

In order for Multiframe processing to work ideally you need enough ram per thread to render complete frames per thread so essentially you have 8 frames rendering at 1 time instead of 1 or 2. If you don’t then there is far more CPU moderation involved as data is constantly re-cached to ram so the CPU threads can finish frame data. This add’s significant latency to the process besides not rendering as many frames at 1 time as the system has threads. In this case it’s better to single frame render where you only need enough ram for 1 or 2 frames while the threads split the data processing those few frames at any one time. This uses far less caching which can improve speed with lower amounts of ram. The trade off though is the render queue times are vastly longer. In your case that is not a concern but that is the trade if you don’t have enough ram to support that many threads with multiframe rendering on.
The short segment time has to do with AE launching AE processes for each thread. That takes time for the OS and CPU to provision resources and start the process.

The application slowing down will always be the case because the CPU’s are getting interrupted by the higher priority application. Scheduling is then deciding which threads are getting handled by what cores and when. However setting half the CPU’s to left over doesn’t change this that much. That means there are far less CPU threads for Premiere to start with since it’s the higher priority app. However allowing the OS to moderate the threading based on Priority puts cpu processing threads to what is required for the higher priority application. Windows manages this fine. If OSX does not then that is specific to the GCD in OSX.
