Amit bhai, You entered the big world of camera stabilizers like smooth cam, glide cam etc.
The first Movie ever done with such setup was rocky, dont forget the Evil dead ghosts, yes they were glide cams :005:
I appreciate your efforts & congratulate you for acheving 2 things:045: ..
1. Appropriate counter weight to balance the go pro.
2. Using the castor wheels instead of a gimball.
You have acheived roll & yaw.

Good Ideas in the big world of DIY well done.What I like is the smoothness acheived in the footage, but the setup has a mind of
its own, you have to manage that.
Now we have to understand that you obviously are intersted to shoot gliding videos in the desert.Believe me even with a
profssional glide cam its not a good idea to it fix on a moving car, its right place,is in your the grip of your hand which
compensates for counterbalancing & keep the camera fixed on the subject. I have recently bought myself a professional camera stabilizer for my Dslr,which is a pain to setup but when you acheive proper weight distribution & balancing its a bliss.

Your setup seems good but you should consider more that one anchor point. Driving on the tarmac is fine with one anchor point, but dont risk it in the desert.
Roll, Pan & Yaw are basically the 3 components represented by the movement of 3 axis, Your setup has no pan at the movement.
For keeping the object in focus you need to control the pan, a simple & cheap way is to use a rubber band.For your case you must use 2 to avoid any unnecessary jerks the camera is recording,i.e from moving left & right.These 2 rubber bands will provide you nesessary focus & keep the camera in the direction you want without the unwanted jerks!. For this you have to do further modifications to accmodate & fix the rubber bands, also you have to consider changing the target easily.
Just an example...



Lastly,do the thinking, calculations & setup before you start the drive, once in the drive stopping frequently will be a obstacle
& disaster for the whole convoy.Once the setup is acheived do your drive with full priorty towards the vehicle & not the recording.

WOW....Thank you so much.....Quite a exhaustive explanation to what I've done!!!! Frankly, I wasn't thinking so much in the technical aspect of photography cause i don't know anything about photography.....Thats why i bought a GoPro and not a D-SLR, Just mount it and hope to get a good shot!!! Of-course editing could add to the magic...but again I am still a newbee at editing!!

The only reason i did this is because i was kinda bored of the static mount and would get 3 hrs of footage in the same angle and getting some exciting footage for editing was difficult...

Really appreciate your explanation, and hope to learn more from you....really like the rubber band idea, will try to incorporate it!!


About the mount.....I am not too worried....I have seen single suction cups holding a flag, i hope it can hold this setup.....And yes, i am in the desert because driving is my passion.....this is just a add on!!!

Hi

Good job. I like it.

i think 2 small plastic or thin metal sheets acting as fins would help.

One to direct the camera forward and one to keep it level. This would tend to keep pointing it in the same direction, but still allow the movement you have at the moment.

Movable fins would be great. If you want to point rear wards, just move then to the cameras end.

regards
Paul

Hi
Not sure from your video, if the camera moves too much, can it hit your car?
Small screws or pins in the wheel could limit the max movement to prevent damage.

Regards
Paul

Thanks Paul!!

Was thinking of exactly the same thing and done it....Now works perfectly!!! In keeping with the NO BUYING ANYTHING/Go GREEN concept, Used one of Neha's empty Face Wash container!!!

This is the point, to have footage from the whole area and not statically pointing front or rear. We have enough videos in the club and it is starting to be boring to watch them.

This is something new, which can bring some other view to our driving, e.g. catching all the convoy and additionally the whole scenery.
