as per 12/2020 how many cores / threads of proc can i utilize?
thank you for all efforts
Depends entirely on the filters being used. For editing and previewing unfiltered clips, I see 4 to 12 cores used depending on codecs involved. When filters are added, it depends on how well the chosen filters thread.
At export time, there is potential for a software encoder to use any idle cores. If Shotcut is using 12 cores to build a frame and the box has 16 cores, the encoder can make use of the additional four cores if it threads well. libx264 and such do thread well. Others may not.
There are many variables. Generally speaking, the best performance comes from 8 to 16 really fast cores rather than 16+ slow cores, especially if using hardware encoding.
