Great video. Just kind of trails that I ride so I know the amount of bumps and bounce and the Osmo coped perhaps rather too well as you say! I have an Osmo mobile and have decided not to risk my iPhone on it on my bike but might look at a mod to add my GoPro. Do you have any pictures of the mount that you used and thoughts?
Not being a rocket scientist I didn't employ rocket science to do the mounts. It was shot on the standard Osmo which uses the x3 camera.I didn't mount my android phone on the handle, half the time I used the phone to aim the camera looking at its screen then would turn it off and put it in my back pocket, other half of the time I just guessed where the camera was pointing using the handle joystick. I definitely wouldn't suggest people use an Osmo mobile to do this - a few jolts and the phone will shake out of the holder.
So - 3 only mounts, then just pointed the camera in different directions to get the various shots. The day was hot as' so didn't spend much time composing shots.
1. Handlebar mount: this is using the DJI Handlebar mount. I have modified it slightly to work better by stretching it's internal spring out then compressing back onto the spring with a carefully tensioned cable tie. There's posts and YouTube talking about it. It worked flawlessly.
2. Helmet mount: This is using the DJI sticky helmet mount and the DJI extension cable. (The sticky mount won't mount to a mtb/road-bike helmet because of the air vents stopping it having large enough surfaces to stick to. I had to file in grooves to the helmet mount and connect to the helmet with cable ties). I used just the gimbal mounted onto the extension cable/helmet-mount (to get the weight of the handle off my head). I mounted the other end of the extension cable to the Osmo handle, and mounted this on the DJI handlebar attachment, attached to my handlebars. I velcroed the extension cable along the top bar of my bike to stop it getting caught on branches.This allowed me to start/stop the camera as I was riding, plus allowed me to change angles remotely with the other rider just guessing it was pointing at him. This gave amazing stabilization: mountain bike dual suspension - my body - my neck/head - gimbal. As you see I hit overhanging branches a few times. I didn't review footage between takes, we wanted to have fun riding, I was surprised when I saw my back pack bobbing into frame when I had the camera pointing backwards on my helmet. I ended up liking this as it really showed how hard and well the gimbal was working against the movement of my body.
3. Tyre-cam: gimbal/extension clamped onto seat post under seat with a small light attachment I had hanging around, and as above, ran extension cable up to handle mounted on handlebar. On the video you can see this when I'm shooting between my legs. The gimbal performed amazing taking out the up and down movement of the tyre and my leaning of the bike over on corners, the tyre is on suspension but the bike frame/camera still was jumping up and down. Compare the movement of the other rider as he mimicked my movement.
I can't work out how to link to a reply I did on this forum previously, but I have discussed in more detail my thoughts on how to get good bike footage, maybe you can search for my replies (?).
I recorded sound from the handle with the supplied little mic. The Osmo never missed a beat, The build quality on all of the components is very professional and solid. That being said it still is a hi-tech complex piece of miniature camera equipment, don't expect it to take knocks and drops, get a gopro if you need your camera to take punishment. I have never had a problem with sound, picture, sdcard recording, dropped communication with phone, or anything else. It blows my socks off what it can do. I've looked at the raw footage on a big UHD screen and stood there stunned at the quality and feeling it gave. Unfortunately the biggest problem in this era is how to get that quality onto the Web for the masses. I look at the fantastic quality of footage coming from mavic/phantom but then realise most of this is slow moving "compression friendly" footage, not fast action foliage which makes h264 etc fall apart on successive generations. This isn't a criticism of DJI, just an acknowledgement of the limits of current world technology.
