It seems that:-profile: v 3 is used (and effective) only with a ProRes
transcoding:

http://en.wikipedia.org/wiki/ProRes_422

Here are some transcoding examples (from EnKoDeur-Mixeur).

--> MOV:

commande linux_dependances_portables/ffmpeg/ffmpeg -i
"/home/angelo/blender/billes.mts"  -vf yadif -s 854x480 -r 25 -vcodec
mpeg4 -acodec copy -q:v 2 -threads 4 -y
"/home/angelo/a/nouv_EKD/video/version_3/avchd/avchd_mts_to_mov_00001.mov"

--> VOB:

commande linux_dependances_portables/ffmpeg/ffmpeg -i
"/home/angelo/blender/billes.mts"  -vf yadif -s 854x480 -r 25  -acodec
copy -q:v 2 -threads 4 -y
"/home/angelo/a/nouv_EKD/video/version_3/avchd/avchd_mts_to_vob_00001.vob"

--> MPEG2:

commande linux_dependances_portables/ffmpeg/ffmpeg -i
"/home/angelo/blender/billes.mts"  -vf yadif -s 854x480 -r 25 -vcodec
mpeg2video -acodec mp2 -ac 1 -ar 22050 -ab 64k -q:v 2 -threads 4 -y
"/home/angelo/a/nouv_EKD/video/version_3/avchd/avchd_mts_to_mpeg2_00001.mpg"

-->  MPEG4:

commande linux_dependances_portables/ffmpeg/ffmpeg -i
"/home/angelo/blender/billes.mts"  -vf yadif -s 854x480 -r 25 -vcodec
mpeg4 -acodec copy -q:v 2 -threads 4 -y
"/home/angelo/a/nouv_EKD/video/version_3/avchd/avchd_mts_to_mpeg4_00001.mp4"

--> H264 MPEG4:

commande linux_dependances_portables/ffmpeg/ffmpeg -i
"/home/angelo/blender/billes.mts"  -s 854x480 -r 25 -f mp4 -c:v
libx264 -acodec copy -threads 4 -y
"/home/angelo/a/nouv_EKD/video/version_3/avchd/avchd_mts_to_h264_mpeg4_00001.mp4"

--> HFYU (.avi):

commande linux_dependances_portables/ffmpeg/ffmpeg -i

-acodec copy -q:v 2 -threads 4 -y
"/home/angelo/a/nouv_EKD/video/version_3/avchd/avchd_mts_to_motion_jpeg_00001.avi"

--> DV (.dv):

commande linux_dependances_portables/ffmpeg/ffmpeg -i
"/home/angelo/blender/billes.mts"  -target pal-dv -threads 4 -y
"/home/angelo/a/nouv_EKD/video/version_3/avchd/avchd_mts_to_dv_00001.dv"

--> DVD (.mpg):

commande linux_dependances_portables/ffmpeg/ffmpeg -i

"/home/angelo/a/nouv_EKD/video/version_3/avchd/avchd_mts_to_dvd_00001.mpg"

--> Transport Stream (.ts):

commande linux_dependances_portables/ffmpeg/ffmpeg -i
"/home/angelo/blender/billes.mts"  -vf yadif -s 854x480 -r 25 -f
mpegts -q:v 2 -threads 4 -y
"/home/angelo/a/nouv_EKD/video/version_3/avchd/avchd_mts_to_transport_stream_00001.ts"

--> DNxHD (.mov):

commande linux_dependances_portables/ffmpeg/ffmpeg -i
"/home/angelo/blender/billes.mts"  -vf yadif -s 1280x720 -r 25 -b
60000k -vcodec dnxhd -acodec copy -threads 4 -y
"/home/angelo/a/nouv_EKD/video/version_3/avchd/avchd_mts_to_dnxhd_00001.mov"

I hope this can help you.
