Thank you so much for your quick response.
“What kind of rendering do you do? Effects? Downconversion to SD? Colorcorrection? Something else?”
Effects: Not too much. Dissolves, slo-mo, B&W, a few more effects but generally it’s clean video and audio.
Downconversion to SD: Mastering back to the PDW-F70 XDCAM deck. This is what takes all the rendering time.
Color Correction: minimal
