“Multimedia refers to content that uses a combination of different content forms…Multimedia includes a combination of text, audio, still images, animation, video, or interactivity content forms.” (cit. wikipedia)

Some preliminary tips (you more likely not to understand at all why I’m bothering you with that) to face video stuff.

General Workstation configuration. Any computer, no matter its Operative System, needs to be configured to be used as a given purposes production machine. The configuring operation implies several tasks, depending on hardware and all components: best thing is to perform an online search with parameters like  “optimized your_model_computer your_operative_system workstation_use”.   In our case and based on our purposes, we should search something like ” video multimedia gnu_linux ” ,  screening results to find the one which best fullfil our needs and scrupulously follow instructions. Furthermore, when working in any specific field (on Gnu Linux system as in any other one) there are tools to best perform tasks, so discover and install them any way your distribution allows (for example using synaptic).

Used Video Format. Video format avchd will be considered as preferred in this manual, its resolution is 1920×1080 while so called hd web format is 1280×800. The first value used as input format and the second as output are the basic you possibly need to know to record footage and publish it online.

Configure Opengl Environment

OpenGL is a specification, a system for rendering interactive 3D graphics that works as a feature of your card driver and Mesa is its open-source implementation.

Install necessary libraries:

freeglut3  freeglut3-dev binutils-gold g++ cmake libglew-dev g++ mesa-common-dev build-essential libglew-dev libglm-dev glew-utils

it should work now, to check type:


Configure linux on macbookpro

I’ve been using Debian or recently Linux mint Debian on different apple laptops, there are basic issues to solve and other distros may differ in solutions, but not that much.

Important to bear in mind following topics:

Synaptics Touchpad + Backlight + Volume + CD Eject button

install pommed


Install isight-firmware-tools

Cinelerra is the most powerful video editing software under Linux and this a short and effective guide to install and run this software

I’m a long term Cinelerra user (since 2003 and I’ve written different howtos (but More’s law applies to software so) I keep upgrading stuff. You may find some of my contribution in different projects (if they’re alive, I mean projects). Indeed I contribute in cinelerra common  manual project.

Given different versions around details to have this software installed at this best and features may vary: it’s the way this software developing works. If you simply needs stability and just to be able to edit, found your version and stay on it.

Here cinelerra-cv  packaging for different distros is available  I wouldn’t spend too much time having programme installed. Although you can download different packagings and sources, amongst all variants actually available I’ve chosen the so-called 5.1 because it is an attempt to join different version. It’s not well tested neither documented, but worthy to try as basic issues as import and export are properly handled.

Keep in mind you’re here to edit video, don’t play to be geek if you aim to be a video maker. Don’t trespass following line unless you want to build cinelerra from source.

To compile package, first of all check dependencies:

cd cinelerra-5.1/bld_scripts

$ sudo sh <os>

git clone git:// cinelerra5.1

$ sh

$ ./configure

( check configure options in README)

$ make

$ sudo Make install

Once programme is installed, open it and check preferences:




I assume footage from sd card avchd is used (using hdv or dv is outdated unless your trying to recover old material).
