MuLab for Windows contains an integrated movie recorder with which you can record all screen activity together with all sound that is going out of MuLab. This is handy for creating MuLab demos and tutorials for on YouTube etc, or to visualize a problem report. Note that this movie recorder feature still is an 'unofficial' function, it's not guaranteed to work on all systems.

How It Works

This movie recorder function is only available via a shortcut to "Toggle App Movie Recording". So go to the main MULAB menu -> Manage Shortcuts and add a shortcut to that function. That's only to be done once off course.

The first time you use this function you'll get the option to choose a codec. Your choice is then stored in MuLab/User/Settings/AppMovieRecorder.Txt If you wat to choose another codec, delete this text file and you'll get the codec choice again.

The size of the video will be the same as the current project window. If you want a specific size then right-click the title bar of the project window -> Edit Size. Do this before you start recording the video.

The resulting AVI files are saved in the MuLab/User/AppMovies folder.

Codec Tip

The CamStudio Lossless Codec is an interesting codec because it's free, it's easy to install and it delivers perfect screen quality, because it's a lossless compression. Ok, the resulting video files are larger (also because all audio is always stored as plain 16 bit stereo, not mp3) but the resulting muvie is high-quality. This has the advantage that the video file is perfectly editable in other video software without adding extra (de)compression noise. And when you upload it to YouTube it might take a bit more time, but that's only needed once, and then the online muvie is high-quality too

Known Issues

• Don't do "Audio Setup" while recording a user movie, otherwise the app will hang.
