I tried a test last night on your suggestion for a 15sec. clip..add v2 track with graphic, select drop shadow, bar goes red on top in timeline. From there I could not click on the next tab, the next open sequence? And batch export is greyed out?
For your Quad core you can get 4 cores all working in compressor. Here is how:
System Preferences – QMaster – Select Compressor under the Service tab and then click the Options for selected service tab. Number of Instances should show 1. Change this number to 4 Click the bottom right ‘start sharing’ tab.
NOTE: To use this setting you must select the new cluster when you hit submit in Compressor.
Example: Hit submit…setting importance is high as normal…where it says “use this computer”…click the drop down and pick the ‘cluster’
You are all set! Watch your compression work with ALL 4 Cores! And at Blazing Speeds. Hope this helps and if you know anyone on the render issue please pass my question on. Thanks.
