Maybe that is the key to getting a good audio capture? This option is not available in gtk-recordmydesktop that I can see.

This is, I think, because the codec divides the frames into blocks of 4x4, 8x8 or 16x16 for compression. Ogg Theora (the video codec I believe recordmydesktop uses) obviously requires multiples of 16, and 600/16=37.5, so that doesn't work. 592 and 608 on the other hand, are multiples of 16, so those work.

I never got the sound problems that severe as in your recording, it just went out of sync for some seconds. But that's nasty, if you say "and I click..." and the video is already showing the result. I have one further tip for getting the right size. Use the commandline version of recordmydesktop and a "special" wall paper for your desktop. <a href="http://www.23hq.com/rstein/photo/3309535" rel="nofollow"> <img src="http://www.23hq.com/23666/3309535_03ac12f7c0007972a3a9dc7b01356f4a_mblog.jpg" height="135" width="180" /> </a> commandline: <code>recordmydesktop -x 100 -y 100 -width 800 -height 608 --no-sound -fps 15 -o video.ogg</code> Everything that is in the rectangle is recorded.

commandline:

recordmydesktop -x 100 -y 100 -width 800 -height 608 --no-sound -fps 15 -o video.ogg

Everything that is in the rectangle is recorded.

Here is what I have so far: 1) Since recordmydesktop does not record sound reliably, turn off sound recording (in gtk-recordmydesktop this is a checkbox that should be unchecked). 2) Use gnome-sound-recorder (in Ubuntu this is in the Sound & Video apps under "Sound Recorder") to record sound simultaneously while doing the video capture with recordmydesktop. 3) In order to make sound synchronization easier for Rolf, use the "stopwatch" application and after starting video click Start in the stopwatch and read aloud the first few seconds as displayed on the stopwatch. Move the stopwatch out of the way, and then at the end of the video move the stopwatch back into view and read aloud the (still running) seconds again to put down audio sync markers at the end of the video (need a CLAP! board). 4) Rolf has requested that video be 800x600, and the closest that I can seem to get with recordmydesktop is either 800x608 or 800x592. A test window can be put up and a desktop ruler (like kruler for example) can be used to size the window, then in recordmydesktop use the Select Window button to pick the window. A quick test video and check inside Totem Movie Player to verify size (clumsy -- is there a better way?). 5) Send the video and audio files separately to Rolf and he composites them together in his video editor. Anyway, just working with what I have... better ideas welcome. Rolf: I’ve been doing some experimenting with recordmydektop to try to come up with a workable (and free) solution to desktop recording.

You say "And now let me go ba[ck] to a show..." and the word "back" (I assume) is where the glitch occurs. Is this just on my setup here, or do you also hear it? Was it a deliberate edit, or a true unintended glitch? The reason I ask is because this is very much like the glitching I got with recordmydesktop, and so I wonder if it is a problem with Linux audio in general, or something more specific.

I think the challenge idea is a good one because it encourages people to try new features and methods that they would not otherwise use. So the process is educational regardless of whether one solves the problem. Rolf: Yeah, Wilhelm is way too over the top (though actually I use William quite a lot).
