Hello,

I am running usability studies where I am videotaping our
participants faces and recording the screen output as well. When I
go to watch the footage afterward, the two clips are never
synchronized, and so I have to play them in two windows and
painstakingly synchronize them by quickly double clicking the pause
button until they line up. This seems like it would be a common
problem, but I have yet to find a really good software solution.

What I am looking for is a tool that would let me play two video
clips in an offset, but ganged manner, such that I could rewind or
scrub through one, and the other would still be synchronized
afterward. Does anybody know of such a tool? I've been considering
writing something to control two VLC instances from a common
controller, but I'd hate to reinvent the wheel.

Thanks!

--Andy

Hi, Andy. (Full disclosure: I am a user experience researcher at the
company that makes this product.)

Morae by TechSmith is designed for usability testing. It records
video of the computer screen along with a camera video as a picture
in picture image automatically synced. You can also take notes that
are indexed to the video, and make highlight videos quickly.

You can learn more (feel free to download the trial) at:

Hi Andy,

I'd suggest you grab a copy of QuickTime Pro. You can copy and paste
the two videos into the same movie, and then offset them to play them
back and scrub the way you want to. Depending on the video formats,
you will need a reasonably powerful machine.
