Daily video log app ubuntu like Jake Sully's from avatar

There are a number of applications that can record video from a webcam. I can't say which is the best for what you would like to do, as I don't know how closely you would like your video logs to resemble what we see in the movies.

Here are some that seem to be more popular than others (in no particular order):

• Cheese ⇠ you may already have this on your machine
• OBS Studio ⇠ very popular tool, though a little overwhelming for some people at the beginning
• Kamoso
• Webcamoid

There are also a bunch of video recorders that are primarily suited for video surveillance, but can be used to record from a webcam (or external camera) in a number of video formats, with or without the motion-detection start/stop element enabled.
