<pre style="white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">A static time driven frame rate is usually a bad guess. Either the value is too high and you'll queue up image requests, or too low and you get worse results than the system would support. A better approach is to start recording the next frame a slight amount after the current one has been processed. It's very easy to implement as well: Just call something like
QTimer::singleShot( 10, this, SLOT(recordFrame()) );
in recordFrame(), and use a boolean flag to stop recording.

<pre style="margin-left: 1em; white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">I'd be curious about the maximum framerate that can be accomplished on your machine.</pre>

<pre style="white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">the directory name should somehow hint that it is related to Marble. e.g. "Marble-Screencasts"</pre>

<pre style="margin-left: 1em; white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">actually in case the ffmpeg or avconv binary is found the bmps should rather get stored into a temporary directory.</pre>
