FFMpeg is a widely used tool to encode video, but often it's driven by a (third-party) GUI. This allows users to easily select their settings like codecs, resolution and what not more. It's also very suitable as a video-encoding test, also because it can utilize up to eight cores. I will use this benchmark for CPU's with at least two cores.

My benchmark method is starting FFMpeg using this Batch script:

@echo Started at %date% %time% >> Bench.txt
@FFMpeg -y -itsoffset 0 -threads 8 -i "Doom.m4v" -ss 00:00:00 -t 00:02:00 -vcodec libx264 -b:v 1000000 -vf scale=640:480 -f mp4 -map 0:0 -map 0:1 -strict experimental -acodec aac -ab 128k -ac 2 "Encode.mp4"
@echo Finished at %date% %time% >> Bench.txt
del Encode.mp4
As video input I use a recording from DOSBox playing Doom.
