Using a ShuttlePro with Kdenlive

I bought a little hand friendly thing with a lot of buttons and wheels – a Jog-Shuttle called “Contour ShuttlePro v2”. It’s supposed to make video editing a lot easier by putting most of the functions you need on the fingertips on one hand. With mouse and keyboard there is a lot of moving around.
I got a bit of trouble while setting it up – so here is my write up for later reference – perhaps mostly for me after a reinstall.

Getting Kdenlive to recognize it

Out of the box some key work as mouse buttons and the wheel acts as a mouse wheel. The other buttons do nothing. But Kdenelive doesn’t find it.

I followed the manual and set up an udev rule. Get root and create the file /etc/udev/rules.d/90-contour-shuttleXpress.rules . Put this line into it:

SUBSYSTEMS=="usb", ATTRS{idVendor}=="0b33", ATTRS{idProduct}=="0030", MODE="0444"

Now we have to find the device address. Open a console and enter

fgrep Contour -A4 /proc/bus/input/devices

My output was:

N: Name="Contour Design ShuttlePRO v2"
P: Phys=usb-0000:00:1a.0-1.1/input0
S: Sysfs=/devices/pci0000:00/0000:00:1a.0/usb3/3-1/3-1.1/3-1.1:1.0/0003:0B33:0030.0001/input/input3
U: Uniq=
H: Handlers=mouse0 event0

The event0 in the last line is the number to be entered at Kdenlives dialog – in my case as /dev/input/event0.

Now Kdenlive found the thing an I could set up some keys. (Findig a good keymapping is another thing….. ) But the wheel made funny stuff – like the mouse wheel. Somehow Kdenlive got the events in duplicate – as mouse wheel and jog-shuttle. Chaos.

In a mailing list I found the solution: disable xinput for this thing. Look for the device by

xinput --list

I found the line

   ↳ Contour Design ShuttlePRO v2 id=8 [slave  pointer  (2)]

And with the line

xinput set-int-prop 8 "Device Enabled" 8 0

I got rid of it in xinput. The first 8 is the id of the device, the second one is magic.  😉

Now it works like a charm.



One thought on “Using a ShuttlePro with Kdenlive

  1. Thanks for your post! It helped me a lot installing my brand new ShuttlePROv2. Not a flaw!
    I’m really liking it and begin to figure out the (*my*) best buttons configuration. Would you be kind enough to share your own configuration and help your readers to get inspired ?
    Here is mine. I use it on the left hand (trackball on the right).
    1-2 : Beginning-end of clip.
    3-4 : ” – ” of project.
    5-6-7 : Select-Cut-Move modes.
    8-9 : In-Out
    10 : Favorite effects
    11 : Play/pause
    12 : Add selection in timeline
    13 : Switch monitor Clip/Project
    14-15 : Zoom out-in

Anything to add from your side of the computer?
