Re: [Avid-L2] Re: Symphony 6.5.x only using Cpu 100% During Video Mixdown?

My understanding is that in Activity monitor when the CPU reads 200% that means it's using two cores worth of processing. 300% would be 3 cores worth of CPU. 1800% would be 18 cores worth. Even though there are 12 cores there are 24 virtual cores as each core shows two cores in activity monitor. I don't recall if the two cores per actual core is "Hyper Threading or Threading or some other term." Perhaps someone can clarify the proper nomenclature.

I agree about the rendered sequence and I think that is why my initial observation of my rendered sequence mix down was only 100%.

That makes no sense, a rendered sequence (if the codecs are the same) requires close to zero CPU as it's just a copy command.

Btw, what kind of Lingo devaluation has Apple invented for 100%?

If Namyr is running 1800%, that is more than double plus good.

(And that's not the only comparison between 1984 and Apple that can be made....)

My Win box runs all cores, if it needs to render or transcode.

(That means, also on a mixdown if that's involved. Same codec mixdown is a plain copy, and as expected, close to zero CPU)

Is your sequence already rendered before mixing down? I think that might have been a factor on my sequence.

Could be just a 6.5 thing. I'm on 8.3.1 and mixing down to prores using %1800+ CPU on a dual 6 core mac pro.

There may be some confusion here between multiple "processes" (separate sw executables) and a process utilizing multiple "processors" (multiple hw CPUs). For example, MC and background transcode are separate sw processes, both/either may utilize multiple hw processors/CPUs.

This might not be true any longer, Terry. I was testing render in-to-out the other day, on a dual 6-core, and it looked like CPU usage was above 1000 %. You've got me wondering, though; I'll double-check it today.

MC isn't using multiprocessors. ASFAIK the only process in MC land that does is the transcode process as that is newer code outside of MC.
