<div><blockquote class="gmail_quote" style="margin:0;margin-left:0.8ex;border-left:1px #ccc solid;padding-left:1ex">I had a much simpler idea: overlay the previous frame on the video field, offset<br>by the desired amount (say, 70%). This is what many consumer digicams do in
<br>panorama mode, including my cell phone. It is then obvious to the user to turn<br>the screen until the overlaid image aligns with the camera output. Based on the<br>Video Chat/Virtual Whiteboard mockups, it seems like we have accelerated alpha
<br>on top of video on the LX, but I don't know this for sure...<br></blockquote></div><br><div>Well, that's just so much better! That makes a lot of sense, and requires no extra CPU (apart from the compositing, as you mention). I'll take that idea into account and mockup a few screenshots for how this could integrate with Record when I get a chance.
