I have 2 machines running W10. A desktop with 12 Gig main memory that can only use Virb Edit 3.6. A laptop with 8 Gig main memory that can process Virb 4.2.
For grins - I put the same source file through Virb Edit on both machines.
The Desktop with 3.6 completed the processing in a little over 40 minutes.
The Laptop with 4.2 completed the processing in approximately 1 Hour 40 minutes.
I understand some of the difference in processing time can be attributed to the difference in the size of the main memory, however, a full hour more processing time????
Secondly, importing the file into Virb 4.2 takes about 20 minutes account of the 'Preview' processing that Virb 4.2 performs.
Virb 4.2.3 is a dog!
