The PK301 comes with some windows software to covert files fro playing on its internal SD card. It's a customised version of Arcsoft media convertor.
The software settings as I can extract them from the arcsoft software are:
Video Resolution: 720x480
Video bitrate: 1536Kbps
Video Frame rate: 30.00
Video aspect ratio: 3:2
Video codec: Arcsoft H264 codec
Audio codec: PCM, 44100Hz
I'm a newbie to both video editing and kdenlive. Is there a profile which matches this so I can prepare movies directly in kdenlive? Or how can I create a custom profile?
Any help appreciated. I find the different video formats absolutely bewildering.

It's a little painful trying to learn. I can't find any documentation.
I can set a project profile, but the render profile seems to use a different set of info. When rendering I can't select the project profile. I'm trying to create a custom render profile. The options *seem* to be ffmpeg options, but they are slightly different, so I can't be sure.
So far I have:
f=avi vcodec=libx264 s=720x480 b=1536k aspect=%dar acodec=pcm_s16le ab=128k ar=44100
I need to set aspect ratio to 3/2, but I've been all through to profiles looking for a syntax example, but they all use the variable %dar.
