> Hi,
>
> I want to share how I record screencasts for Pharocasts http://pharocasts.blogspot.com/ in case someone wants to participate. Now there's 11 screencasts. The difficult part is to have a good idea / scenario for a screencast. Comments and ideas are welcome.
>
> If you want to publish on Pharocasts I can give you write access. Or if you have a "draft" screencast I can edit it / re-record it for publishing. I try to record screencasts with a minimum duration of 5 mn.
>
> These instructions are for Linux (but I'm a beginner in video stuff). I don't know which software to use on other operating systems. Have advices ?
>
> I record with xvidcap http://xvidcap.sourceforge.net/. I define a capture zone of 800x600 (use 4:3 or 16:9 standard resolution. If not you can have poor encoding results).
> Set multi-frame mode (you have to right-click on the file button to access preferences, not very intuitive).
> I choose AVI format / MPEG 4 codec.
> If you open / close applications for the screencast, note that KDE has very good options to memorize / force windows positions, so they are always opened in your capture zone.(Other window managers like E17 have these sort of options).
> The trick is to not stop recording when you write errors, you can cut the "wrong" parts later.
>
> To edit the video, I use avidemux http://fixounet.free.fr/avidemux/. It has Qt and Gtk GUI and work on Linux / Windows / OSX / BSD ..... It's really easy to use. When you want to cut a part, you define the beginning with the A button ( Ctrl-[ ), the end with B button ( Ctrl-] ), then Edit -> Cut ( Ctrl-X ). You can navigate using arrow keys.
> When finished, click on save (Choose another filename !!).
>
> So now you have your screencast in .mpeg file. Note that people using MacOSX Tiger or older have problems to watch this video. So I convert in .mov using ffmpeg http://www.ffmpeg.org/ like this:
> ffmpeg -i my_video.mpeg -b 500k my_video.mov.
>
> (but I think it's not the best command as the video size is bigger and quality lower).
>
> To publish the video I use Vimeo http://vimeo.com/. I've tried YouTube and Daily Motion but the quality is lower or the video duration is limited. I had problems using the "standard uploader", so I switch to the "basic uploader" on the download page, works better.
>
> It's really fun to record screencasts, and a good way to show development practices.
