2012-11-11T08:51:40+02:00

Multithreading Simply put, multithreading is splitting a computer process over multiple threads. If you happen to have several CPUs, the threads can then run in parallel, cutting down the processing time needed. In the case of many modern computer chips, they can have multiple internal cores, meaning they are in fact many CPUs in one chip. Avidemux supports various degrees of multithreading.
