about 9 years ago I bought a MiniDV camera. A long time ago just used it, but with the issue of having videos on youtube I have dusted and I've been seeing what can be done with it on a computer with Ubuntu 9.04
The camera records in PAL SD (720x576 25fps). The MiniDV format has the advantage that you can edit and easy access to each image, but has the great disadvantage that its compression is minimal. That is, the videos in this format are huge files. In particular, video recording at a rate of 28.8Mbps and audio to 1Mbps, so in total we are talking about 30Mbps. Ultimately, each minute of recording involving a 225MB of space if you decide to dump these videos on your hard drive.
So we find two steps to solve:
- Capture video on your computer.
- Convert video to a format more appropriate to use you're going to give it.
The video camera is connected to the computer via a cable IEEE1394 (Firewire). The team successfully finds the connector 1394, but it creates an entry in / dev / (including / dev/raw1394) until it detects that a device has been connected.
As capture software in the repositories can be found kino and dvgrab. Since the capture with kino is very simple, we will use this program.
$ sudo apt-get install kino
Before using Kino, said that in version 9.04 of Ubuntu is a problem with the creation of device / dev/raw1394. We can overcome the problem or using sudo kino launching from the command line:
$ sudo kino
Or, changing the permissions of the access point device (remember that previously you need to connect and switch the camera to the system to create access to the device in question):
$ sudo chmod 666 / dev/raw1394
If kino launched without making this change, we will see an error message (kernel side raw1394 module not loaded or failure to read / write / dev/raw1394 ", or pertaining to the language version you have installed the system) and will not be able to perform the capture process.
After this change, we launched Kino, and select the option to capture. The program is very intuitive. With the default options, the program turns the video clips in separate files (each shot is a separate file) in directory we have indicated.
the end, we will find a few video clips of very considerable size with which we can proceed to editing or format conversion.
