Failed Time Lapse

Thursday, September 4th, 2008

Two days ago Melissa and I drove from Berkeley to San Diego. We drove on US 101 for most of the way, but used Hwy 1 between Monterey and San Luis Obispo. The weather was fantastic and the scenery beats I-5 any day, even on 101. It does take longer, but it’s worth it if you don’t have arrive at the destination at any particular time. I wanted to record the journey, as I have before, but this time looking forward. Using the Canon A620 my father gave me and my laptop connected to it using USB, I managed to do this without too much interference. However, the batteries on the camera died early on, so I didn’t capture the whole trip, or even the most scenic parts of it. In the future I’ll need to use an external power source.

I am sharing it because there’s no harm. It’s not very good, so I didn’t bother to add any music. Below the video you can see rough route the video covers on a Google map.

The video lasts 1 minute 44 seconds, is 5.6 MB in size, and the frames are separated by eight seconds.

This is the first time lapse that I’ve time-stamped. I felt it was useful as without the time-stamp, it’s hard to tell exactly what time it is, especially at night. It also allows you to see how traffic changes with each rush hour.

I think this time lapse would have worked pretty well with a very short interval, perhaps a second or less. Obviously, I couldn’t have run it for nearly two days, but it would have converted the traffic from random noise to the main subject. The most interesting stuff happens in the second evening when various mists and clouds come in, so feel free to fast-forward to that.

The biggest problem with this time lapse is the huge number of frames don’t actually contribute to the study. I could shorten the 10 minute running time by increasing the frame rate (or by not including all the frames), but at higher rates the traffic just looks even more random. Things would work better if the view changed much more smoothly.

Cleaning the Compy

Sunday, October 14th, 2007

Found while cleaning my computer, above is a short movie I made a long time ago showing me on TV at the 2002 Tour de France. I’m near the top of the Col du Galibier, which is one of the highest passes in Europe and is used by the Tour de France nearly every year. In the above still image I’m on the left of the frame in a Cal Cycling kit with my yellow Cal hat on. You can hear me yelling ‘¡venga! ¡venga!’ as Santiago Botero (who is Columbian) sprints by for maximum mountain points. Here are one and two and three different views showing how I looked that day. Oh, and here is me and Laurant Jalabert, a two-time Polka-dot jersey winner. I’m pretty happy with how that photo came out.

2007 Collegiate Track Nationals Video

Friday, September 21st, 2007


Quicktime video
24min 33sec, 152.71mb

Above is a video I put together documenting the 2007 Collegiate Track Nationals. I put this race together over the last 10 months (along with a great deal of help from others, especially Chris Nekarda). Held at the San Diego Velodrome, over 100 collegiate cyclists from around the country competed over three days. My team, UCSD, did quite well, and at least one UCSD rider was on every podium.

You can watch the video by clicking on the image above, or if that’s giving you problems, right click here and select ’save link as…’ (or something similar depending on your browser). Then you will play the movie off your hard drive. You’ll also need the most recent version of Quicktime on your computer for either method. If you have a reasonably fast connection, clicking on the image above will start playing the video right away.

Some notes: If I had planned my video a bit more before the event, I could have had done a better job (imagine that!). In particular, a few of my teammates are under-represented in the video, which was purely accidental. I would have liked to have a more even coverage of everyone.

I hope you enjoy the movie. Thanks to Chris Schroeder for letting me borrow his DV video camera, and Chris Nekarda for a few still photographs in the movie.

A Drive to Newport Beach

Here is a neat time lapse of the drive from my apartment to Melissa’s maternal grandmother’s house in Newport Beach. I set my camera up on the tripod in the rear section of my Volvo station wagon. I held the tripod down with a few bungee cords, but you’ll notice that the camera moves slightly through the duration of the movie. I’ll have to devise some sort of better securing mechanism for future efforts. In particular, I’d like to figure out a solid way of having the camera point forward on the dashboard. I cropped the images to remove the majority of the inside of the car as it isn’t very exciting.
