You should really copy and paste the output instead of attaching a screenshot.
For what I can tell your preset file contains the option "directpred" which is now called "direct-pred".
Apart from that it's very unlikely that it makes sense for you to specify such settings manually, you should almost always use exclusively one of the presets build into x264 itself.

Sorry for providing very brief description on the issue.

Here is the complete update on the issue,

Basically we are trying to convert a multimedia file (of any format) to .mp4 format using some third party presets.
Attached here with filename (test.ffpreset).

We have imported this preset into winff tool and tried to convert a multimedia file(.flv) to .mp4 file. The preset

selected in the tool had the value as "-f mp4 -acodec vorbis -aq 30 -ab 128k -ac 2 -ar 24000 -vcodec libx264 -

fpre test.ffpreset -b 330k -s 640x360 -vf pad=iw:ih+2*60:0:60 -strict experimental -threads 0"

Conversion was unsuccessful with below error
"Unrecognized option 'directpred'
libx264-ingenico.ffpreset: Invalid option or argument: 'directpred=3
', parsed as 'directpred' = '3'"

Later we tried by changing "directpred" to "direct-pred", again it was unsuccessful with below error

Please use -b:a or -b:v, -b is ambiguous
[NULL @ 032a5f60] [Eval @ 0022e6fc] Undefined constant or missing '(' in 'mixed'

[NULL @ 032a5f60] Unable to parse option value "mixed-refs-dct8x8-fastpskip-wpre

Error while opening encoder for output stream #0:0 - maybe incorrect parameters
such as bit_rate, rate, width or height

Could you please suggest us a solution on what preset values should be used for above mentioned configurations.
