I'm new to ffmpeg and video transcoding. This command seems pretty slow. I'm
using it to get rid of b-frames. If anyone has any tips on how to accomplish
this faster, it would be much appreciated. 

ffmpeg videoToEncod.mp4 -y  -preset faster -acodec libvo_aacenc -ac 2 -ab
128k -vcodec libx264 -b:v 2400k -r 29.97 -s 960x540 -g 15 -flags +loop -cmp
+chroma -partitions +parti4x4+partp8x8+partb8x8 -me_method umh -subq 6
-trellis 1 -refs 1 -coder 0 -me_range 16 -sc_threshold 40 -i_qfactor 0.71
-bt 2400k -maxrate 10M -bufsize 10M -qcomp 0.6 -qmin 10 -qmax 51 -qdiff 4
-level 30 -threads 0 theNewFile.mp4 2>&1';
