Recording with a camera using Cheese
Recording the screen with an external camera has the following advantages over recording with a screencast:
- Recording a whole session, even if the user restarts Tails.
- Saving the video directly to your computer and not relying on the computer used for the tests.
You can use a document camera. The Ziggi-HD Plus by IPEVO works fine from Tails.
Move the AF switch of the camera to C to have continuous autofocus.
Install Cheese:
apt install cheese ffmpegthumbnailer
In Cheese, choose ▸ Preferences and adjust the video resolution to find a good trade-off between resolution and fluidity.
On my ThinkPad X250, I use 1280 × 720.
Adjust the orientation of the camera to capture as much of the screen as possible while not obfuscating the light of sight of the participant.
