screen capture lock and freeze
I was recording a lecture that was demonstrating the use of an Excel spreadsheet. In the playback, at about the 20th minute it just stopped tracking the movements of the cursor, and this locked image remained for a long time (until the next frame change). Any ideas what's causing this and what I can do about it?
I’m frustrated

Inappropriate?Hi Bob,
Would you mind sending a link to the presentation to support@panopto.com? I'd like to take a look and see if I can learn more from the screen capture, specifically whether this is caused by a bug or by heavy system load.
It's possible for any real-time capture stream to drop frames if the processor is under heavy load. For example, if you're opening a large file or starting a heavyweight program (Word or PowerPoint, for example), this can often consume all of your system's resources for several seconds. If that's the case, the screen capture compressor will be "starved" of resources during that time and will be forced to drop some or all of the incoming frames. The best way to ensure a high-quality capture is to close any unnecessary programs while you're giving your presentation.
We are working on improving the efficiency of our screen capture compression in our next release, making it more resilient to sudden spikes in load, but the underlying requirement (enough CPU time to actually record images) is common to all screen capture software.
