    I finally upgraded to Lion, and I hate to be one of those people, but it's been an aggravating experience, quite a few hiccups with MobileMe syncing, total confusion with versions and resume, an iPhoto scroll bar bug that's too complicated to explain, and I'm at a loss for words over Address Book--once the simplest most utilitarian application, now incomprehensible. I finally figured out the whole app is controlled with the red bookmark tag and I won't go on because the loss of that simple, elegant app to its current state is painful . . .

    But the most vexing so far has been my issue with Quicktime which, when recording video at the same resolution as in SL, now uses twice the kbts/sec creating files that are twice the size. It also runs the fans much louder. I record video using the built-in iSight camera on my mid-2010 13" MBP. I continue to select the lowest recording quality mode of Medium. Yet the fans go up to 6200 RPM and the video file size is twice as large. I have inspected the movie properties of files recorded under SL and Lion, and everything is the same (codec, resolution, etc), except for the kbts/sec. In that regard Lion uses about twice as much data consistently. The resulting quality of the videos is identical from what I can tell--and it's pretty easy to tell if you open up a 320x240 video full screen. That 2x data usage and 2x CPU usage is not adding to the end product.

    I don't dare call AppleCare with this problem because I have trouble explaining more basic issues to them (such as what safe sleep mode is, or the last representative I spoke to who insisted my computer's battery was removable for the purpose of resetting the SMC when mine is the new sealed "will void your warranty if remove it" battery--she insisted on getting the instructions for me to reset the SMC when I already knew how). I don't think Apple could help with this unless I could speak to an engineer.

    I am sorry to vent so much. I've just had a hard day, and this upgrade didn't go like I had hoped. Does anyone know 1) How to change the parameters of the way Quicktime records video using Terminal or 2) How to contact an Apple engineer?
