Why is the field limited to certain ammount of symbols?

Wanted to play with parameters and test few videos with this: -crf 15.0 -vcodec libx264 -acodec libfaac -ab 192kb -coder 1 -flags +loop -cmp +chroma -partitions +parti4x4+partp8x8+partb8x8 -me_method hex -subq 6 -me_range 16 -g 250 -keyint_min 25 -sc_threshold 40 -i_qfactor 0.71 -b_strategy 1 -threads 0

but it allows only this much :D
-crf 15.0 -vcodec libx264 -acodec libfaac -ab 192kb -coder 1 -flags +loop -cmp +chroma -partitions +parti4x4+partp8x8+partb8x8

Thank you for your time!
happy new year!

The problem is just that the max length of the field defaults to 128. I increased this to 1024:

Note that a lot of the flags in your example should not be put in the extra params field as bd_video generates them automatically.

vcodec, acodec, ab and g are output directly by bd_video.

bd_video uses presets that come with FFmpeg. On the first pass it uses libx264-fastfirstpass on the second pass it uses libx264-hq (both attached).
