I took some video of my timed runs for the first time in quite a few events, mostly because I wanted to figure out how I was hitting so many cones in the last few events without noticing them. I used a couple of cheap $40 HD "pocket cams" aimed both forward and backwards. I really wanted to see the backward view the most, so I gave that cam the highest mount on the roll bar in order to get a good view out the back window. Unfortunately, that meant that the forward-facing camera got the lower mount, which didn't give a very good view of the track--too much cockpit and not enough course in the frame. I'll have to rig up a different mounting point if I want to do this again. Also, the front-facing camera saved the clip in Quicktime format, and I don't have Quicktime installed on my PC yet, so when I processed it in Windows Movie Maker I lost the audio track somehow, and the clip has no sound. :banghead:

I was pushing a little too hard on all of my timed runs (out of fear that Hassan would beat me, since Gary told me right before my timed runs that he was running 59s in practice) and I had several big "moments," especially coming down the hill in third gear, but the second lap seemed to be when the tires hit the sweet spot for temp and pressure. My third lap was slower by a few tenths. At least I managed to stay out of the cones and run clean on all three laps for the first time this year, so the rear-facing camera served no real purpose, but I uploaded the clip anyway, since it has sound:
Front view
Rear view

As I suspected when I first saw the course map, the lack of any long straights rewarded handling over horsepower--just look at the Miata times on this track! It was very busy, but not necessarily slow, since I was still in third gear twice on the course, once through the slalom and again coming down the hill through the "esses". I can't complain, since it was my best result of the season so far! Thanks to everyone who worked so hard to let us all have some fun driving our cars, and especially to Erik for not running and letting me have a chance for the top BRI time!

Tom, Try using race render software for your video. You can import almost any video or data format into it and do a split screen (front/back) and sync them for an interesting view of the track. I've used it with some of my track videos and it's fun to play with. http://www.racerender.com/RR2/Features.html

I was very impressed with the times that you and Hassan put up.  :bowdown: My best practice laps were high 59's, but I was unable to repeat those on tho old NT01's that I was using. I thought the track was a lot of fun, especially the uphill and top sections.

What a great day, great track and great driving by so many people. For a track that looked like it would not favor a 911 platform I was surprised to see so many rear-engined cars do so well. And, the track was much faster than it looked on paper so kudos to the track setting/design team for making it flow so nicely. I was within spitting distance of TTOD but Mike A. and Mark K. were too much for me. I guess I can dream...maybe someday... :banghead:

John Straub, Thanks for the compliment on my car(#511); Tom too. It took a lot of time and effort and a LOT of help from John Chambers, Greg Palmer and Jae Lee. John, I love the picture. Would you mind if I use it in my Forum profile? Thanks again.
Jerry.

Mr. Tweed That front facing video with all the warping perspectives is like driving while on acid...

...ummm...not that I know what that's like. Nice lap! :rockon:

Thanks for the tip, Mark. That does look like interesting software for combining data and video. It would be fun to sync both views side by side in a video. It looks like the Pro version of the software costs more than the camera did, though! I went ahead and installed Quicktime for Windows on my laptop and apparently, that supplied the proper codecs to keep the sound with the image properly. When I ran the clip through Windows Movie Maker again, it rendered it correctly, so I went ahead and uploaded a new front view with sound:
http://www.youtube.com/watch?v=bMEK4XvyXfE&feature=youtu.be

I didn't bother putting titles on it or anything, though, as the camera perspective is just too low. Unless you drove the course, and know where it's going, the lack of visual clues from being able to see the cones right in front of the car makes it difficult to follow, especially when the car heads uphill a little and the cones disappear even more. :( Next time I'll rig a new mount for it higher on the roll bar. A wider angle lens for the camera would be nice, too--that's one great feature of the GoPro, but it's a $300 piece of equipment. :shock:

Ahhh, yes, I would also deny any knowledge of what that would be like, at least when my grandkids were around... :roflmao: The '60s were a long time ago, now... But actually, that warping effect was added by YouTube--when I first uploaded it, the site said "Your video is shaky, do you want us to correct it?" I mistakenly clicked on "yes" and their post-processing did the distortion thing on it--really a weird effect--"warp speed" for sure! I'm reverting them back to the original versions right now.
