Thanks for the video - very useful. However, not seeing how you got the color-correction utility into the browser, I had to search a bit, and when I did find it, clicked once, but nothing happened. I ended up clicking again, and again, and only when I clicked on the video itself in the timeline did I see that I had three copies of the threeway colour correction window. And now it wouldn't work, presumably because you can only have one window of the same utility open for it to work. How do you close the other window??? Won't go in the trash, won't respond to ctrl click, then 'close tab', because it just reappears... It's not obvious how you get rid of the tabs once you have opened them. Any ideas?? Apart from that, a very useful technique. Thanks.
