how to use GLC

GLC doesn't have a graphical user interface: it uses CTRL F8 and CTRL F9 shortcuts. Be sure these shortcuts are available on your system, eg they aren't already in use. GLC will stard recording when you press CTRL F8. Same shortcut to stop recording. Press CTRL F8 again to resume recording: this way the new footage will be added to the first one. If instead you want to create additional separate recording files, use CTRL F9.

GLC and Second Life

GLC runs in background from the moment you start your Second Life viewer. I created a simple Bash script to manage this. Ask me how to do this if the following instructions aren't clear.

The script includes a single line that runs GLC with some options, included where to save the recording files and how to call them. It also includes the complete path to the viewer to be runned, with its additional parameters.

glc-capture --fps=15 --resize=1.0 --disable-audio --out=/PATH/TO/YOUR/VIDEO/DIRECTORY/SL-%year%-%month%-%day%-%hour%-%min%-%sec%.glc /PATH/TO/YOUR/SECONDLIFE/VIEWER --set AllowMultipleViewers TRUE --set Language it

Notes:

  • 15 FPS may appear low, but the videos I create with these settings youtube.com/user/OpensourceObscure look smooth enough. I think that by limiting the GLC recording framerate, I also limit the overall system load, so that more resources are available to the SL viewer. (is this clear?)
  • yes, the "--resize" option is redundant when set to 1.0. I think resizing adds computing load on the system, so I avoid to do it when recording. I use to set my SL viewer window size to 1280x720, which is an ideal size for digital videos. I suggest you to do the same if you don't know what you're doing. If you use this option, know that 0.5 is said to be more resource efficient than other values. You can always resize your recording later.
  • I don't need to record my audio. You may want to remove the "--disable-audio" GLC option if there are interesting sounds in the scene you're going to record, or if Voice is being used. If not, I'd suggest you to disable audio recording; you may add a good soundtrack later (I do this directly on YouTube, after the upload, thanks to its AudioSwap feature; Nine Inch Nails ftw).
  • Be sure to replace the two "/PATH/TO/YOUR" occurrences with appropriate paths in your local filesystem
