<div style="word-wrap: break-word;">Cool -- I wonder though if it would be better if it were placed in a different method, drawFrame or something (very much an up in the air sort of question)</div></blockquote><div><br>drawImage is already overloaded, so why not carry on with that, unless we change the API as you suggest below.<br>

Otherwise you have to record the current location in the video stream, then scan to each location you want to blit, draw, and then return to the original position. Which could easily result in weird visual behaviour for the user (as the video element flickers a few random frames while you do your previews or whatever).</div>
</div></blockquote><div><br>AFAIK we'd basically have to implement that by creating a second video stream, seeking it and then capturing the frame, and you really don't want to do that synchronously! Then we'd want to cache that stream so that another drawFrame with a nearby frame index was efficient ... ick. So I suggest not offering that API. Authors can always use a second, hidden video element to achieve the same effect.<br>
