Hi, I'm new to CTA3 and enjoying it so far!
I was wondering if anybody knows what influences the export speed. I've started CTA3 on my 2011 Mac mini i7 and recently upgraded to the new Mac mini i7.
There is not much difference in how long an export takes, so I tested it on different systems:
I used the 810 images Demo for Camera transitions and animation curves beach scene.
Windows 10 PC, 4-core AMD FX8350 4GHz, 16 GB DDR3 RAM, GeForce GTX 970 4GB GPU, SSD. Export to mp4 1080p: 2m:07s
Windows 10 PC, 4-core Intel i7 4780 4GHz, 32 GB DDR3 RAM, GeForce GTX 960 4GB GPU, SSD. Export to mp4 1080p: 42s
Mac mini, MacOS 10.14.3, 6-core Intel i7 8700B 3.2GHz (4.6GHz Turbo boost), 16 GB DDR4 RAM, Intel UHD Graphics 630 1.5GB, SSD: 1m45s
Seeing the faster time at the Intel PC, I thought the GPU is the driver for export, just like in Premiere Pro or Final Cut Pro. But my Mac mini with integrated GPU is faster than the PC with the fastest GPU, and the other PC with the smaller GTX 960 is much faster than any of them! Drivers and OS updates are all up to date. The 970 is has double the bandwidth of the 960 (256bit /128 bit)
The Mac mini has by far the fastest CPU with the latest 6-core i7. So I don't see if the CPU or GPU drives the performance here. Is it single core or multi core processing. Looking into the graphs while exporting, the CPU is below 50% and GPU is also about 20-25% at all systems.
What do I have to do to get faster export times? I am planning to get an external GPU (Thunderbolt 3) for my Mac Mini but don't see any reason if this makes it faster.
Thank you all in advance!
