Reduce recording time

Currently to record a video of 5 minutes, we've to set time out for 300000, which is not really efficient. Is there a way to speed up the task, for example speeding up internal recording so that if there is enough machine resources, the recording for 5 min video is actually finished in 30 seconds?

Any help or thoughts would be really appreciated.

The plugin just records the browser window, so if you would want to speed up the recording you would have to increase the fps and e.g. speed up the video/animation that are playing in the browser.
