Holy crap umd. That's one of those videos that is cool to watch but I hope I never end up with one of my own. How hurt were you guys and how were the bikes?

umd, that crash was nasty, I hope you heal fast. What I notice in sprints is that you always have to pay attention not only to riders swerving/maneuvering to take a line and, in this case, to lead out guys in front sitting up.

Nice, but for how long was that guy visible to umd? I think it was that guy in front who darted across and jerked to the side with no warning who should have been paying better attention.

Anyone know the secret to eliminating wind noise like in this video?

I had an incident like that earlier this year; fortunately I was okay quickly. I hope you're all good.

As far as everything else goes, looks like a normal sprint. Actually, it looks really smooth and safe.

Finished up a clip. A few more to go I think. New Britain Crit, the Tuesday Night World Championships, Palomar/Wohlford descents (not HD), maybe some vehicular motorpacing. I have footage from past years to edit too but they aren't in HD.

I criticize a bit more readily in this clip for some reason, probably because it's more obvious, even on cam (which hides a lot of subtleties).

Enjoy

Last week's race (posted in the road race section as well).
Filmed via my go pro on my handle bar.

Woo, the credits were a bit slower this time. I could read them without pausing. I couldn't believe that guy swerved around the manhole cover. You're not cornering over it.. just go straight over, dude!

carpediemracing 

I had a few seconds to play with on the credits, so they're about 15 seconds, not 10. The 10 minute limit made it tough sometimes - I'd start with 12-13 minutes of "critical" footage and work it down. Now it's 15 minutes but I think 10 will still be a decent limit.

The swerving really annoys me (can you tell?). It's really dangerous. This rule applies on group rides as well as races.

Part of the reason I do these clips is to try and spread knowledge on what to do and what not to do. This is one of those "not to do" things.

SteelerHoo

a video from the same weekend racing on the whole track. the corkscrew is a blast!

BasicJim

Great video, SteelerHoo! Good enough to have me yelling "GRAB HIS WHEEL!!"

umd

I just wanted to post an update. I will not allow this to devolve into a debate about who's fault this was, or continue the bickering from other threads.

From Jeff, the guy that I made initial contact with: "I still don't blame anyone. crashes happen..."

From Dan, the guy who went down hard and went to the hospital: "Many thanks for posting the video. Looked at it frame by frame and confirms what I remember. Important considering I don't remember anything post-crash. I'm dumbfounded by the comments posted. Don't pay the antagonist haters any mind. The cause was and is pretty obvious. Hope you are feeling okay..."

Blackdays

cdr, great video as always.

SteelerHoo, I really want to race the Sea Otter classic some day. Racing on Laguna Seca looks like a blast! Are you from Pittsburgh by any chance?

Here is two vids of me riding on my trek 1.5

I was watching a video from a race that I was in. As i was watching I was thinking 'who's the loser with his seat too high?'....uh oh....that's me. all fixed now.

I know this has been posted somewhere....but suggestions on a handlebar mounted camera?

Flatballer

Same question as save10, really. I'm considering starting to film my rides and races, partly for fun and partly (for the races anyway) to learn from mistakes, see what I'm doing wrong.

What cameras is everyone using? Is the GoPro the main one? What are the pros/cons of handlebar versus helmet mounted? The GoPro HD is much more expensive, but can take MUCH longer videos, which seems necessary for cycling (8 hours of 30fps 720p all the way down to 4 hours of 1080p (which my TV can't even display... I only have 1080i currently)).

Looks like around $300 for a full setup with 32Gb SD card ($70) and buying the camera from Amazon ($230) plus a mount.

umd

CDR, SteelerHoo, and I use the ContourHD.

Flatballer

That looks pretty nice. A little cheaper and sleaker too. I like the easy on/off slide, pretty slick. The 720p one seems perfect, I can't even watch 1080p on my big flatscreen, so no need to record it. 720p looks great.

I notice you use handlebar mount, CDR uses helmet, any specific reasoning? I'd like to use it on my MTB too, but I'm not sure whether my head or handlebars would be more still through rough stuff. I'm thinking my head but I'm not sure.

I think I'd lean towards helmet mount, since on your bar mount in a pack I feel like I can't see. I always want to lean up to see over people, but I can't. With a helmet cam I feel like I'd get more of the feeling of the race/ride.

carpediemracing 

I tried GoPro (seat post and bar mount), not a fan. I like the ContourHD a lot.

The 1080 allows you to do 720@60fps. The 60 fps is key, I think, really smooths things out.

I use a helmet mount so I can see (and illustrate) where I'm looking, and, to a certain extent, perceived effort (head bobbing etc). I find the bike mounts, used alone, to be somewhat limiting with tactical stuff - you can't see what riders near you are doing, you're not aware of what the rider is thinking (i.e. where he's looking), etc.

For helmet vs bar, I am a bit biased - I rode for many years at night and found that a bar mounted light really limited my speeds on unknown, very curving, technical single track. I prefer a helmet light over a bar mounted light.

As a side note it's easier to consciously film something if you have a cam on your helmet. If a car buzzes the group, I can simply look at the car. With a bar mount you have to steer at it.

Head is more stable over rough stuff (but there is software to smooth footage shot elsewhere). Your body is a huge suspension system to keep your head relatively stable. In motorsports they found that measuring Gs at the ear made the most sense - anywhere else and there was a lot of extraneous forces at work. At the ear it's very very consistent.

Helmet mount makes the picture viewpoint high. A few people have asked me why their videos seem too high compared to mine. I point out that I'm short on the bike.

btw not sure if ppl know this but umd's "slow for crash then rear ended" bar/post mounted dual cam clip was misunderstood and used to try and ban helmet cams in USAC racing. The proposed ban failed (in fall 2009). I fought pretty aggressively to make my position known on helmet cams, how they record both good and bad things, and that, if necessary, they can be used to confirm dangerous riding and therefore levy appropriate punishment.

umd

Hmm, I don't think that could have been me, I never used a cam in a race until this year.

The main reason though that I switched to a bar mount instead of helmet was to make it less conspicuous. I was getting a lot of flak from some people who felt that it meant I cared more about getting footage than racing. On the bars means that a) most people don't even notice, and b) I cannot actively do anything to affect the recording, so the recording does not affect my riding.

It's funny too, because one of the comments in my thread about my crash before it was closed was that I caused it because I was "concentrating onteh camera looking for impressive footage". So on the bars, I just strap it on, turn it on, forget about it, and I don't have to worry about crap like that.

carpediemracing 

oops. Who had the dual cams, one pointing forward, one backwards, crash in the sprint of a race, cam rider slowed to a stop, then POW rear ended by a sprinting rider?

umd

Not sure, was it in CA?

carpediemracing 

I think CA. I just figured it was you. Prominently posted here on BF. Who else does a lot of helmet/bike cams?

I use a GoPro HD. Battery life is around 3 hours which translates to 10-11 Gigabytes of footage taken at 720p @ 30fps. For this reason I mostly use a 16GB SD Card. I have tried both helmet and handlebar mount and have now settled on handlebar (in the drops) mounting for the forward facing camera. As umd has mentioned, with the camera on the handlebar you just turn it on and forget about it... it is also relatively unobtrusive. When I had the camera mounted on the helmet, some people looking at the footage say they felt nauseated. It can also be difficult at times to keep the camera leveled when it is helmet mounted.

The GoPro HD has a 170 degree wide angle coverage when in 720p mode so it captures the action in front nicely even when fix mounted on the handlebar.
