Error FFMPEG when convert video to MP4 with baseline presset
This looks to me like an actual issue with the scripts in the preset vs your build of FFMpeg.  It appears that the syntax of options being passed to the encoder are incorrect (particularly something related to "wpred" and a missing parens) and since they are not specified in your command line, I can only assume it is the preset that is the problem.  I would suggest trying either a different version, a different build or a different source for your copy of FFMPEG and see if you have better luck.
