ProRes renders
Just cut a documentary in prores 1080/25 which we’re now finishing. During the “offline” I’ve had render settings at 50% and had no problems, but for output to grading suite reset to 100% (obviously) and nightmares began. Quite a lot of the shots have speed effects or resizes on them and some motion blurs. Impossible to render the whole timeline as the machine crashes, so rendered several clips at a time and it’s slooooooooow. In all it took about 9 hrs to render a 1hr sequence – is this normal????

2 things
1) Source codec: you don’t mention what that is, but if it is not native ProRes 1080/25 the you are looking at render time. Obviously the more processor intensive the source codec (HDV, XDCAM etc) the longer that render will be.
2) Motion Blur: this is a processor hog and will significantly impact on the overall render time … a simple test suggests something it increases render time by a factor of 5 or thereabouts.

the whole project and media is in prores 422.
I suppose one of the real problems here is that almost nothing (and I mean simple resizes and speed effects) is seen is a full res realtime effect for output and so has to be rendered – the prores codec is clearly very clever but appears to place a massive hit on the processors.
