Is Compressor a serious product?
-
[Gabriele Sartori] ” Normally what I do I export with a lightweight codec”
Which codec? Perhaps Compressor is only getting a 32bit decode out of it?
-
Also, if you are getting multithread performance from FCPX, why not make a Compressor setting and export to that setting right out of FCPX?
There’s a preference setting to use the GPU from FCPX if you want to do that as well (which may or may not be why your CPU is not running up).
If you want actual help, I would suggest posting actual workflows, no matter what the experience.

I can’t speak to Apple in detail but with my background working with the Telestream Episode Encoder developers, they were often asked the same question regarding the cores maxing out.
Their general response was that the goal of compression isn’t to “max out” the cores. It’s to use the resources necessary for quality and speed (depending on your settings). If the encoder is efficiently designed it may not need to max out the cores. Sometimes maxing out cores is a result of less the optimal programing.
Of course HandBrake could even be less efficient but still faster (perhaps as a faster car may actually be less fuel efficient). It’s just that maxing out the cores may not be the best litmus test for faster.

I can guarantee you that we are in front of a marketing crafted BS answer. If you use 30% of your CPU and you are able to go to 60% you will encode in half the time preserving all the other technical choices and the identical quality. These answers are really upsetting because they offend the customer intelligence

Who is “we”?

I have no clue about this at all so it’s only a question.
When you talk about processor usage, isn’t it logarithmic, so twice as fast as 30% would be 130%?

[Gabriele Sartori] “we are in front of a marketing crafted BS answer.”
No, my conversation is with coders not marketing people. Depending on the codec and the encoder, more CPU cycles don’t always mean faster. There are times when more CPU cycles are simply wasted cycles. Just as more bits doesn’t necessarily mean discernible quality improvement.
Perhaps it’s the “more is better” is the marketing hype. Sometimes more CPU cycles (or more bits) helps but sometimes they don’t.

Trust me, I developed H264 compression routines for 10 years. That is not true. Giving a good code if you fill twice the pipelines you go twice as fast. It is a basic law of physics. (and math as well). The “engineers” were giving the marketing party line as they are directed too.

If adobe media encoder uses 100% but encodes at the same speed as compressor what does this mean?

Space and time have been ripped apart. We will never be the same again.
