Not necessarily. The source monitor is just the player. There are no GPU acceleration elements involved nor caching involved with that. It’s strictly disc read requests to processor decoding and straight to draw out on the screen. When the Program monitor is active now you have the Disc read requests, Decoding from the player, Data buffers to ram for GPU acceleration components, encoding to Mpeg I-frame codec and then draw out on the screen. The entire pipeline is much longer which shows latency problems far more. The drobo latency may not come into play just playing a file back but when you have all of the above processes required to playback along with media cache files for audio then the latency will become an issue. It’s a simple test by just taking the Drobo out of the equation. Use another external drive or an internal drive long enough to test the playback latency on the timeline. See what it’s like. However that Drobo is significantly slower than that 4bay Areca storage unit I listed in the previous post due to that virtual raid. This is well known throughout the IT industry for Drobo’s. Their great for archive but the performance drawback is too much for work drives.

How big a Media Volume raid do you need?
Add what drives you need to that.

Drobo’s are good for archive but not as work/media drives. The Virtual raid slows down the bandwidth performance and significantly increases latency. Do not use them for work drives. A single Thunderbolt drive would be better in this case. Use the Drobo for archive which is what it’s meant for.

Drobo’s are significantly slower due to the virtual raid they employ. What happens if you use a different drive whether Thunderbolt or internal?

Are all the media and cache files on the Thunderbolt drive or are some on the Drobo?

If the Bravia is handling 24 frame media then likely it doesn’t have support for most PAL frame rates especially via HDMI. Often times the TV manufacturers only program the firmware based on the market the TV will be sold in. It is not uncommon to have EU and NA to have variations of the same model with the differences firmware only. Also keep in mind the EU has more stringent laws regarding the makeup of electronics such as panels due to environmental laws. This means the manufacturers have to run different production lines for these devices anyway which further increases the likelihood of different firmware versions.

AMD cards are not what you want for Adobe on Windows. I suggest getting an Nvidia 760GTX card. That would far outperform that AMD card with Adobe. You may try to resolve the Open CL buffer issue your having by updating to the latest catalyst driver here.

AE uses threads for more than just the Background Render processes of the multi-frame rendering. Leaving those cores available for AE doesn’t mean you need to use all of them for multiframe rendering. That is decided by how much ram the system has overall and how much you set for each thread. What is set for each core/thread is more decided by what is required for that comp than necessarily required to run all cpu cores/threads for the background render. Often running enough ram per core leaves more than enough cpu cores/threads available for the other processes AE uses. The point however is to let AE and the OS have whatever CPU cores available based on what is scheduled and moderated by the OS. The OS is far more efficient moderating that on average than we are since processing conditions constantly change in these applications. Its far easier to go back and adjust for a special case that is performing less than ideal than lose processing efficiency 100% of the time.

How much ram do you have in your system and what are the over all system specs? AE 2014 so far seems to be showing larger ram usage and profiles in general especially if previewing in full res.
