I'm not Bill, but I used to wonder the same thing. I ended up buying VideoPad from NCH. Well worth the $40 or so. Very easy to use. You can even upload directly to Youtube from within the software.

I use Apple QuickTime Pro for video editing. I'm no computer guru but find the software easy to use. I'm using only a very small part of its capabilities.

Even basic (e.g., free) QuickTime has a "trim" feature that is easy to use. I use it often to pare down a session's video file to the one or two laps I want to study and save.

What do the color blocks represent as it relates to the tires? Did I miss the explanation?

It's relative load on the tires. It's 2D and does not account for vertical acceleration, which the VBOX does not measure.

I took the Gt4 to Summit Point main for the first time. Conditions weren't ideal and I made a few mistakes but ran 1:22.14

Still a little ways to go to catch up with Chris H., whose time looks close to a pro time to me.

I was at Tbolt this past weekend, and seemed like every 991 GT3 except mine was on Hoosiers.

Bill, how are the CCW's with 265's compared to your old set up of OZ with 235's?

P.S. ---check out orthojoe's public service announcement on 19" wheels and brake pad sensor wire fraying !!! ___EDIT --saw your post on the other thread so nevermind!

Nice driving Bill....interesting hand positioning with the 10 & 2. I'll have to try that to see if it keeps me from shuffle steering holding the wheel at 9 & 3.

First time at SP in 2 years, Sat was mostly wet and cold. I ran all but the last session Sun on the old 235/295 setup. I wanted to heat cycle the new setup so took a guess on initial tire pressure and ran the last session with the 265 F. Temps were in the mid 50s and there was a lot of traffic so only got a few flying laps before a Black flag ended the session. I perceived more front grip and I set the fast lap then but the tires were new and at their best. I'm running WGI with Metro, I have lots of WGI data so will have better info after that.
