Nearly all my work at present consists of rendering HD-recorded living history interviews for storage on Blu-ray M-discs. I have settled on the Sony AVC 1920x1080 60i with audio separately rendered to AC-3 to optimize quality with file size.
I was just watching some tips on Derek Moran's site, one of which discusses improving rendering times. I had never looked at this, having learned that my graphics card, a Radeon 6450, was not CUDA compatible. I assumed that I had to use the CPU ( i5 2400) to render. He shows where to look for options: after selecting a rendering template, Customize/System/Check GPU. In my case, this displays "Open CL available." Also, on the Video tab, the two Intel Quick Sync options are available under Encoding.
Is selecting a matter of pure trial and error, or am I likely to be able to use one of these to decrease rendering time? Should I just take a short video -- say, 10 minutes -- and time with CPU only, Open CL and Quick Sync Quality to see which is fastest? Are there other considerations I should be taking into account?
