Light, camera, action..Kino!
Kino is a program to capture video from your camera to your
computer, to manipulate your movie (only basic features are
implemeted yet but hopefully there will be more in the
future) and to export it back to your camera.
Kino uses the ieee1394 (i-link, firewire) protocol to
communicate with your digital video camera. For this purpose
you need to have a firewire card in your computer. I am using
the Exsys-6501 firewire card (www.exsys.de) which works very well
All recent Kernel versions (I use 2.4.18) have IEEE1394
support. You need to enable the following IEEE1394 related
kernel options at kernel compile time:
You find the homepage of the firewire team that writes the
kernel code at http://linux1394.sourceforge.net/. I recommend
however not to download the kernel code from there but to use
the code that is already integrated into the mainstream kernel
To use the firewire functionality you need to install
libraw1394, libavc1394 and libdv. All three are available at
I used libraw1394_0.9.0.tar.gz libdv-0.9.5.tar.gz
libdv-0.9.tar.gz works as well but it has a bug in its mmx
code. You need to edit the function mmx_ok(void) in the file
mmx.h and change it to always return 1 (return (1);). Version
0.9.5 does not have this problem.
To install the libraries use the usual
Now load the kernel module video1394 with modprobe:
run lsmod and check that the following modules are loaded:
video1394 15344 0 (unused)
There are various ways to automatically load modules but the
simplest solution is to add "modprobe video1394" at the end of
the file /etc/rc.local (redhat/mandrake).
ohci1394 17136 1 [video1394]
raw1394 6896 0 (unused)
ieee1394 24848 0 [video1394 ohci1394 raw1394]
Finally you need a device file which is generated with the
libraw contains the test program testlibraw. If you run it and
the installation was successful you should get the following
mknod video1394 c 172 0
chmod 666 video1394
Now you can install kino (kino-0.5.tar.gz was used for this
article). You install it with:

Connect your camera with your PC via firewire. Then switch
your camera on, start kino (in this order) and go to capture in
kino. You will notice that you can now control your camera with
kino, you can start playback, stop, pause, rewind, etc.
If you now want to capture your movie to the computer first
click on "setup". You will find a very good description of
every button of the set up menu in the manual (under the
topic Kino Preferences) so I won't repeat it here. I just want
to make the following notes:
Under file you have to specify a directory and a filename. The
directory must already exist. If you forget to give a filename
in addition to the directory your movie won't be captured on
If you close the dialog box the specified file should now also
be visible on the main screen.
There is the possibility of auto split capture which will
divide the movie into several scenes when there was also a cut
in the filming and usually works very well.
But for trick films I recommend to disable this option because
otherwise every frame will be a scene which then makes cutting
Leave setup now.
If you now press the red button your movie is captured.
Now go to "Editor", open your movie and press play to watch
Manipulating your movie
Go to Editor for this. So far kino only supports very basic
editing but for many cases you will probably already find it
Go to File and open an existing movie. If you click on Frame
Position with the left mouse button (below on the right) the
current frame number plus the total frame number are shown. You
also see the display of a video player and can play your
selected movie, rewind it etc.
You can copy scenes, cut them and paste them.
Cutting scenes out
You go to the frame before you want to cut and split the scene
in two, then you go to the last frame you want to cut and again
split the scene in two. Now you go to the scene you want to
cut, click with the mouse on it and "cut".
You can also append another movie to your selected movie by
clicking "insert file before frame". The appended file only
needs to have the same format and size etc.
While you are still editing your movie it would be unecessary
to use more disk space than you need. So just go to File-->
Save as and save the Playlist. These playlist files are very
small xml files. They refer to the original AVI files which
were created during capture.
If you are finished with all your editing you can export (not
save) it into one big file on your hard disk or record it back
to your camera.
You can also use the command line that you can see in the
interface of kino. See the manual for the available commands.
Under Timeline you can get a list with the frames of your
movie. How many frames are shown depends on the interval you
have chosen. This can help you to get an overview over the
AVI is not AVI
A note on AVI. AVI is not a specific format of its own (like
e.g. gif or jpg). AVI is a container format. Kino can export
and import AVI in dv2 and dv1 format. dv2 is often better if
you plan to further process the video with other programs.
Jpeg-encoded AVI is also very popular. To convert dv2 AVI into
jpeg-encoded AVI use dv2jpg (sourceforge.net/projects/dv2jpg/)
You can save still pictures from your movie, you can save it to
another avi file and if your camera allows that you can
transfer your edited movie back to your camera.
Export to camera
First switch your camera on, then start kino and go to Export.
Even for exporting the movie to the camera the control button
on your camera should be set to "VTR". It might be surprising
since you normally use this mode to play the video rather than
record, but this is how it works for most cameras and
definitely for Sony cameras.
Select the panel "IEEE 1394" and press the
red button to start the export procedure.
Export to AVI file (not as playlist)
Go to export and select the panel named "AVI". Here you can
select the file type (dv1 or dv2). Use type 2 (dv2) if you want
to process the film further. You can select a file name and
press the red button to start the export procedure.
To get one or several still pictures from your movie go to
Export and select the panel named "Still Frames". Here you can
enter a file name and the file extention sets the file format
automatically. I don't know which file formats are supported
but .jpg and .gif both work fine.
It is also possible to export the sound into a separate file.
But I have not tested this since I always add the sound to my
films after cutting.
