Cinelerra – Professional Video Editor for Linux

Anyone who find Kino is too simple for them, Cinelerra is your choice.

For hardware requirements, you should have at least 500MHz CPU, 256MB RAM and more than 1 GB hard drive space for very small project, an OpenGL display card. For details, please refer to official manual.

Download it here.

Updated on 2007-06-27 :
You may encounter a warning message when you run Cinelerra :

The following errors occurred:
void MWindow::init_shm0: WARNING:/proc/sys/kernel/shmmax is 0x2000000, which is too low.
Before running Cinelerra do the following as root:
echo “0x7fffffff”>/proc/sys/kernel/shmmax

You should add the following line to `/etc/sysctl.conf’ :

kernel/shmmax=0x7fffffff

Then, issue the command :

sudo sysctl -p

Cinelerra does not support OGG video and audio by import but it can render to OGG format. If you load the OGG file, it will crash. I use this script or download here to convert OGG file that complied by recordMyDesktop to MPG.

Then loaded to the Cinelerra, added audio and other stuff or FX. For audio, I selected WAV. After that, I rendered to OGG format via Cinelerra. I then use the captioned script to convert to FLV. The size is very small that fix into YouTube, but be keep in mind that your time and size of the FLV (or OGG/MPG) should not exceed 10 minutes and 100MB.

You also need to install mencoder :

sudo apt-get install mencoder

For the script, you need to copy to the “~/.gnome2/nautilus-scripts/” and

chmod 740 ~/.gnome2/nautilus-scripts/video-convert

Here is my first music video :

Enjoy video making!

Swiftfox

Swiftfox is optimized Firefox. It comes with many editions for your CPU. I downloaded it for my Athlon 64X2 box. It is loading and surfing very fast. I recommend all of you to use it.

My Firefox was left behind on the panel without touching since then.

Updated on 2007-06-21 :
I installed Fasterfox addon as advised by huygens-25. It is running smooth and fast. It also blocked the popup flash in some websites. A real good stuff.

VirtualBox on Ubuntu 7.04

I read a lot of information about VirtualBox. Yesterday, I installed it on my Ubuntu 7.04 box and installed fedora 7, Ubuntu 7.04 SE (it is my remastered edition of Ubuntu), and Windows XP as virtual machines.

Without installing the Additions.iso of VirtualBox :
Windows XP required to give 64MB RAM as display memory to make it to be 1024×768. Ubuntu 7.04 has no problem in it. However, fedora 7 can only be displayed in 800×600.

With installing the Additions.iso of VirtualBox :
Windows XP and Ubuntu 7.04 have no other issue and remained in 1024×768. For fedora 7, I have no time to make it work with additions.iso.

The virtual machine cannot run 3D games or beryl in Linux, too sad.

We back to talk about how to install VirtualBox on Ubuntu 7.04 :

Step 1 :
Go to the VirtualBox Official site and following the instruction to download.

Step 2 :
After the installation, you should do the following :

Step 2a –
Make the USB working.

Step 2b –

sudo chmod 777 /dev/vboxdrv

Step 2c –
Add yourself to the group of “vboxusers”

Step 3 :
Select the VirtualBox from “Application” menu.

That’s all.

By the way, the full instruction is here.

preload for Ubuntu

preload is an adaptive readahead daemon. It monitors applications that users run, and by analyzing this data, predicts what applications users might run, and fetches those binaries and their dependencies into memory for faster startup times.

sudo apt-get install preload

GeForce 8500GT on Ubuntu 7.04

I replaced my ATi X550 to GeForce 8500GT with 512MB RAM today. ATi open source driver cannot run OpenGL 3D games properly but it can run beryl smoothly.

The drivers for nVidia of Ubuntu cannot be worked. It is required to download the nVidia official driver. The latest version by this writing is 100.14.09.

Download the driver from nVidia.com. The following is the steps for installation.

Step 1 :
Press “Ctrl”+”Alt”+”F2” and then issue the following command :

sudo /etc/init.d/gdm stop

Step 2 :
Install the compiler and related libraries :

sudo apt-get install build-essential

Step 3 :
Let’s install the driver :

sudo sh NVIDIA-Linux-x86-100.14.09-pkg1.run

And follow the instructions on the screen.

Step 4 :
Reboot.

Remarks :
You should repeat the captioned steps except Step 2 after updating the kernel or xserver-xorg.

Forgot to tell you that you can uninstall the driver by issuing :

sudo sh NVIDIA-Linux-x86-100.14.09-pkg1.run –uninstall

Enjoy!
