Does Screen Recording with QuickTime has an option of recording only active window?

Welcome to Apple Support Communities

QuickTime Player doesn't record a window, but you can record a part of the screen, that may belong to this window.

First, open the window you want to record. Then, open QuickTime Player, select File menu (on the menu bar) > New Screen Recording, and drag the cursor on the part you want to record

You are welcome

Do they still have that feature in quicktime 10.0 on snow leopard because when I just click new screen recording and hit record it pops up with a box saying are you sure you want to start recording screen? After recording starts you can stop by: click stop then a box that says show me, under it it says pressing command-control-esc. I just am not having any luck because all of the videos that I see of how to record screen are the old version I believe. Does anyone know how to do this now?

This video should help! http://www.youtube.com/watch?v=Im3FO_ZVBCQ

Does Mac os X Lion and above have the drag to record feature? If that's the case, then I might just have to upgrade to Lion. Is there a lot of features in Lion other than drag to screen record and some small things? I have a computer with Mountain Lion and there are some new features, but I don't think enough for me to upgrade my Mac Pro even though I only can get Lion, but I guess I just will have to edit some of the things if I need to when I screen record or whatever. Thanks for all of the help though.
