Meanwhile, a setting of 32 (-threads 32) uses up to 32 cores amounting (at this time) to 43% of overall resources. On my 40-core HP Z840 computer, a threads setting of one (-threads 1) uses one core (that lonely one the third from the right on the top) and about 4% of overall resources. On a multiple-core computer, the threads command controls how many threads FFmpeg consumes. It may be worthwhile running tests on your own clips and potentially limiting the threads count to 4 – 8 threads. However, higher thread counts produced more transientquality issues than lower settings in the ten clips that I tested.
