Note: I am not the original poster.
Just out of curiosity, In Avatar, you see Jake recording a video log quite often. It would be quite easy to pull off in After Effects (add date,time,etc.) to make a video log that looked similar, but is there actually a software that does that without the extra work? i.e. Record from a webcam, add date, time, frame, watermark, then export to video file.
