Using VLC for screen capture

Monday, July 27th, 2009

I recently had to make a screen capture for embedding into a Keynote presentation. As this sort of thing isn’t something I do often I didn’t really want to pay money for a program to do it. Luckily, something totally unrelated happened and I found the solution. VLC, the open source media player was updated to version 1.0. It was one of those programs I had always had installed, but only ever used to play media files. As I was exploring the menus to see what was new, I discovered it was easy to be able to record your screen. Here are some instructions on how to do it.

First you’ll need to download and install VLC.

Open VLC and select File -> Streaming/Exporting Wizard…

1-file menu

A wizard appears. You will want to select Transcode/Save to file
2-streaming wizard

Choose Select a stream. As we want to record the screen, in the input box enter screen://
3-choose input

Choose the format and the bitrate. As I’m using a Mac I’ll choose H.264 and select a suitable bit rate. If you have audio you wish to include you can select the audio option as well.
4-choose format

Select the method of encapsulation – for H.264 it’s good to select MPEG 4/MP4.
5-encpsulated

Select where to save your movie.
6-save to

You’ll then be presented with a summary screen so you can check all the settings. If they are OK, click on Finish and VLC will start to record your screen (including the mouse movements).
7-summary

Once you have finished recording, switch back to VLC and click the stop button. The recording will stop and the file is saved.
8-stop recording

You will probably need to trim the start and the end of the screen capture in another program as the screen capture will record you switching back and forth between VLC to hit the stop button. For instance, if you are using the screen capture in a Keynote presentation you can import the movie into your presentation and then move the Start and Stop markers in the QuickTime inspector to remove these portions.
9-Trim

You’ll now have a beautifully created screen capture movie for your presentation. I hope you find this tip useful.
