There are two hardware PWM channels on the BCM2385/6.

PWM0, which can be set to use GPIOs 12, 18, 40, and 52. Only 12 (pin 32) and 18 (pin 12) are available on the B+/2B, and PWM1 which can be set to use GPIOs 13, 19, 41, 45 and 53. Only 13 is available on the B+/2B, on pin 35 (but I think PWM1 is used for something - is it the audio output?)

# Image File Output

############################################################

# Output 'normal' pictures when motion is detected (default: on)

# Valid values: on, off, first, best, center

# When set to 'first', only the first picture of an event is saved.

# Picture with most motion of an event is saved when set to 'best'.

# Picture with motion nearest center of picture is saved when set to 'center'.

# Can be used as preview shot for the corresponding movie.

output_normal off

# Output pictures with only the pixels moving object (ghost images) (default: off)

output_motion off

# The quality (in percent) to be used by the jpeg compression (default: 75)

quality 75

# Output ppm images instead of jpeg (default: off)

ppm off

############################################################

# FFMPEG related options

# Film (mpeg) file output, and deinterlacing of the video input

# The options movie_filename and timelapse_filename are also used

# by the ffmpeg feature

############################################################

# Use ffmpeg to encode mpeg movies in realtime (default: off)

ffmpeg_cap_new off

# Use ffmpeg to make movies with only the pixels moving

# object (ghost images) (default: off)

ffmpeg_cap_motion off

# Use ffmpeg to encode a timelapse movie

# Default value 0 = off - else save frame every Nth second

ffmpeg_timelapse 0

# The file rollover mode of the timelapse video

# Valid values: hourly, daily (default), weekly-sunday, weekly-monday, monthly, manual

ffmpeg_timelapse_mode daily

# Bitrate to be used by the ffmpeg encoder (default: 400000)

# This option is ignored if ffmpeg_variable_bitrate is not 0 (disabled)

ffmpeg_bps 500000

# Enables and defines variable bitrate for the ffmpeg encoder.

# ffmpeg_bps is ignored if variable bitrate is enabled.

# Valid values: 0 (default) = fixed bitrate defined by ffmpeg_bps,

# or the range 2 - 31 where 2 means best quality and 31 is worst.

ffmpeg_variable_bitrate 0

# Codec to used by ffmpeg for the video compression.

# Timelapse mpegs are always made in mpeg1 format independent from this option.

# Supported formats are: mpeg1 (ffmpeg-0.4.8 only), mpeg4 (default), and msmpeg4.

# mpeg1 - gives you files with extension .mpg

# mpeg4 or msmpeg4 - gives you files with extension .avi

# msmpeg4 is recommended for use with Windows Media Player because

# it requires no installation of codec on the Windows client.

# swf - gives you a flash film with extension .swf

# flv - gives you a flash video with extension .flv

# ffv1 - FF video codec 1 for Lossless Encoding ( experimental )

# mov - QuickTime ( testing )

ffmpeg_video_codec swf

# Use ffmpeg to deinterlace video. Necessary if you use an analog camera

# and see horizontal combing on moving objects in video or pictures.

# (default: off)

ffmpeg_deinterlace off 

motion.conf

I ended up commented these out when i was testing but not totally sure if it helped.

It's prolly ok to leave motion.conf pretty much as it was but this works fine for me and that's how it's gonna stay now it's fully working.
