I need to wait until I have finished the commuter's set-up to see if a seat post mounted camera will be feasible but.

If it doesn't fit on the seat post, you could always put it on the frame down near the axle using one of their 3M Stick on quick release plates.
Or if you have a rear rack you could put it there, I have done that to mine. You can see the resulting video in my opening post. here is a photo of how mine is attached the rear of the bike...

Thanks for the tip on Dashware Graeme. Works great. Just have to work out how to use it a bit better now.



I have now changed the power meter to cadence.

Hi

Graeme

An interesting approach ... how have you found it down low ... that scares me a bit in terms of exposure to possible damage.

Your welcome :) it's nice having the details there in front of you.

It works well, when I first put it there I was worried I would always knock it on things or my legs, but i haven't hit it once yet. I like the low angle, it's just the right height to get rego numbers nice and clearly.

For those that are interested, I have put together a couple of clips.

The first part has the GoPro down low again but facing forward, for something a little different. I have included a bit of rough gravel so you can see how it handles a little bit of rough ground as well as the road.
The second part is with the GoPro mounted on my helmet, I prefer the GoPro mounted to either the H/bar or down low facing the rear. I think it's a lot smoother.
Take note of the noise difference between the two mounting positions.

Have you guys editted the video much? I presume contrast and a very light touch of saturation. This is mine albeit not bicycle related but attached to the 4WD when I went on the dirt track. Speed was about 35-40km/h

No adjustments have been made, I have only trimmed the video or added another clip.

After talking about mounting options it got me thinking and tinkering. I have come up with two DIY mounting options for your camera.
I haven't had a chance to test them out yet, hopefully in the morning.
I have one mounted to the seat post and the other on the handle bar, anyway here is a short video of them...

Hi

Found another option for a rear camera. I assume this is the same one that Nate raves about here. $250 ex Nate or $200 ex USA so not much in and probably better to buy locally, however the GoPro Hero still comes in at a good price with a good reputation, but of couse at a lower resolution. Decisions decisions.

BTW Nate can your one be mounted on a rear stray okay? I am not sure I will have much spare seat-post as I plan to use a Carradice of Nelson Barley saddle bag.

Anyone else played with one?

Well I had time to test out the new mounts today. They didn't work very well , so I had to make some adjustments.

Handle Bar Mount
I had a piece of rubber under the handle bar mount, this allowed the camera to bounce a little and I also had the L Bracket too long, this also allowed for some bounce.

Modification
Removed the rubber and just had a small flat piece of metal between the hose clamp and ballhead.

Rear Mount
The rear mount had to much bounce also, this was caused because flash shoe had to much play in it.

Modification
Removed the flash shoe and just used a small L bracket and hose clamp with the ballhead.

Here is a video, this shows my DIY Mounts against the GoPro Mounts

Really is a shame they haven't included a rack mount with this and extra cable length to reach the rear rack. That camera will be blocked by my Carradice Nelson saddle bag.

It may be in the final release, when people start requesting different things? Or we may be able to make our own.

While I just use the GoPro helmet mount, this looks interesting. But i can't seem to find any details on how it was made.

It looks like it drops the camera pretty low on the front of the helmet?

If thats the case, I wouldn't want it there. If you come off you could end up with a camera in the face. Up top out of the way is the go for me. :)

Nate wrote:FYI - joining front & rear footage with split screen:
its poorly aligned but should look pretty cool if you had 2 cameras, 1 front 1 rear


Here is an example of a split screen video (following Nate’s instructions) with a front and rear mounted camera. The front camera is an Otek DVS126 on a Rigidmount handlebar mount, and the rear is a ‘$10’ key camera (808 #3) with a rubber band mount (as mentioned elsewhere in this forum) on top of a Cateye TL-LD1000 rear light. The Cateye TL-LD1000 is large enough to be a platform for a key camera. I added foam padding to the top of the rear light. This light/camera combo is easily removed.

This is a busy enough sequence with 2 cars wanting to reverse, people crossing the road, and the car in front nervously looking for a park. I normally take a quieter street, but it is flood damaged. I better look for another alternative.

I found instructions for weatherproofing the $10 key cameras by placing them inside a Tic Tac container (the smaller 27gram size). I'm testing this presently. I replaced the base of a Tic Tac container with clear flat plastic, but found this had imperfections which affected picture quality. Something like the clear plastic from a CD/DVD case might be better. Google: key cam ‘Tic Tac’ for instructions and photos.

Ripper - glad my info is helping people!

For the case - you MUST use glass or optical quality materials. There is NO exception to this. I've done a heap of mounts on cars - helllo Mr Stone Chips.
You can fiddle around with glass which is the best & most scratch resistant or
- head to your local Servo
- grab a $5 pair of sunnies (plastic lens)
- pop them out
- use some araldite/silicone & sort it out in 5min
great optics and less glare!

Thanks for the sunnies tip Nate - Now if you see a cyclist with strong mintie breath and one lens cut out of their sunnies, don't run a red light or have a road rage flip-out, because they are filming from both ends. :shock:

I'm surprised with the video quality of key cam. although in this clip the Otek 126 had big sunglare. At the paved pedestrian crossing near the end of the clip, the key cam didn't show more shake or shutter roll that the Otek cam. It's low weight might help here.

And I got the idea how to embed youtube vids :idea:

I had a look at the splitscreen software last night and hit a brick wall, couldn't work out how to get the plugin in VirtualDub for the AVISynth software. Any tips? I like the split screen capability, certainly helps tell the story better.

I took a while to get my head around this. That sort of thing temporarily turns me into a detail freak, until I get it working.

You just have to install both programs- VirtualDub and Avisynth. VirtualDub will use the already installed Avisynth (through information in your .avs text file) to make .mov format files, or join videos together to make a split screen video. You cant ‘start up’ Avisynth, but VirtualDub can call on it (in the background). So it isn’t a plugin.

I just used the script that Nate gave earlier. Just cut and paste this text into notepad (or other text editor):
Code: Select all
a = DirectShowSource("c:\bike videos\front camera.mov")
b = DirectShowSource("c:\bike videos\rear camera.mov")
StackHorizontal(b,a)BilinearResize(1920,540)



then save this as a file named “front and rear rec1.avs” (or whatever you want to call it, as long as it has .avs at the end). This file tells Virtualdub where to find video files and how to join them. The video files you are joining can be in .avi format already.

Next, in Virtualdub select open video file (I think) and select the text file you just made: “front and rear rec1.avs” (or whatever you have called it), then Virtualdub does its stuff.
Possible problems:
- The video files have to be the same size (ie:height x width). I got an error message with that.
- The file names in the .avs file have have the correct name and complete directory (I cut and past from explorer to get the right directory location, ie: c:\bike videos\video1.mov)
- I’m guessing Virtualdub has to know that Avisynth is there to associate .avs files with Avisynth. Could the order that you install Virtualdub and Avisynth affect things.

Hope this makes sense,

Martin
