I'm getting seriously tempted now to buy a camera myself - got some money coming in soon and I need to make some expenses. As a sound designer I think I can legitimise buying such a camera as a business expense! I almost certainly will use one for sound recording.

Just a shame there doesn't appear to be any that take an external mic source other than that really expensive two-part cam. Which I wouldn't mind having!

Currently erring towards the Poseidon as the quality is seriously impressive for the price. Anyone got any low light footage yet? Only thing I saw before was some taken from inside a car which wasn't really relevant.

The newer Contours, have an external mic connection, in fact the newer Contours have bluetooth enable you to see the video image in real time on a smart phone with the appropriate app.

I've got a Poseiden but have not had the opportunity to try it out in low light conditions. I watched the in car night video, unfortunately car halogen headlights help CMOS camera's alot, it's just the sort of artificial light source they need.

Contour GPS video looks ok, but the real resolution doesnt look all that special. Look at the "P" parking sign for example. I'd suggest putting that image quality into a 1920x1080 file is merely a waste of storage space, I'd be very surprised if there were more detail than a good SD camera.

If its really better than your Panasonic HD camera, then Id suggest it was faulty. I have the Panasonic SD60, a fairly cheap mid-range camcorder and that is not even close, especially given the very favourable light conditions in that clip.


That's a 720p file, not a 1080p. Most of the HD helmet cameras will do 60fps at 720p, which is quite useful if you want to do slomo.

I think the Contour+ has an external mic socket.

OK, I understand it was 720p, but I think there is far too much emphasis on the HD aspect in nearly all the samples shown, not just yours. I'm pretty used to seeing the SD output of the 3-CCD Panasonic consumer-level camcorders from about 8 years ago, and I still don't think there is anything approaching the real resolution advertised.

It's not very surprising because getting small sensors (although full marks for the trend of bigger 1/2" or thereabouts sensors lately) and low-cost optics to give you that sort of detail is pretty difficult, the electronics doing the HD is the easy bit, but a lot of the "detail" being recorded is just noise due to the fuzzy image presented to the sensor.

You can easily test it, re-size the video using a high quality scaler (Lanczos or similar) to a lossless file and then watch it on a big screen back to back with the original. It think you are getting about PAL resolution. You may even prefer the lower-res version due to sharpening and de-noising effects of the resize.

I can see a massive difference between the output produced by my Contour and the what is produced by my mid priced JVC camcorder, even though they have the same resolution sensor. The JVC has almost twice the bit rate of the Contour, watching the JVC on a high def. monitor it is just so much sharper and I can zoom in alot further before pixelation becomes a problem.

You haven't recompressed that at all?

Just that looks no better than the upscaled SD footage from cheaper cameras I've seen, but at 60fps. Does running it at 60 lower the image quality?

I think you've misunderstood me. The 1080p Contour footage is better than the 1080p footage of my (new) Panasonic camcorder (HTC-TM40).

The example posted is 720p, because 1080p on a bike handlebar mount suffers from rolling shutter. In 720p mode the Contour has a 135 degreee fov - this mean focus at the extreme edge and right sides is poor.

This is not normally a problem as in motion the edges go to a blur anyway but it is evident if you freeze the video. In 1080p, the focus is consistent across, if I remember correctly, a 110 degree fov. 60fps does also slightly lower the quality from 30fps.

I can post some 1080p footage taken from a car if you wish. This mode should be ok on a helmet mount.

[edit]

Here's some anyway. Bear in mind they are shot through a windscreen and glass reflection is a factor. Audio is removed to screen out the chat! Sunny late afternoon, if I remember correctly.

These were actually shot with a 1.16 beta. I haven't had much time to try out the 1.16 final but it seems to me that the developers may have softened it a little to reduce grain.

Slightly off topic does anyone know how to turn off date and time on the cheap ACT10 camera. The book said its optional but not how to do it.

I don't know if the ACT 10 is anything like the newer ACT 20, but watch this review from YouTube, the guy explains the cameras working really well IMHO!

Looking at it they look the same camera with the ACT10 being a lower quality recording. The review was very good thanks but sadly using the same method does not work. You do however wright a text file to set the time so you might be on the right lines.

Finally, some bike footage, handlebar mount, 720p at 30fps taken today with 1.16:

Debenham

All the above are 25mb downloads or thereabouts.

I'm not unhappy with the quality overall - I've used the ContourHD 720p, the 1080p version, some Flip-style HD cameras and several Chinese muvi clones, both sd and upscaled sd, as well as having access to Go Pro, HD bullet cam and the newer Chinese cheapo 720p units' footage. I think the GPS 1080p footage compares to an equivalently priced HD camcorder, although the 720p mode of the latter will probably be better.

Go up to, say, the mid range Panasonics that start at nearly twice the price and there will be a big jump in quality. You would be comparing chalk and cheese, though, and it's not just about the image sensor used - I wouldn't subject the complex lens of an expensive camcorder to the kind of road vibration that the Contour gets from a handlebar mount on a 50 mile ride.

They all have their pros and cons - how they cope with changing light conditions, quality in low light, mounts that can be plain ugly, high bit rates that require expensive high capacity cards and limit battery life, external battery pack use etc. etc. For example, the ContourHD 1080p has the same optics and image sensor as the GPS unit and (now) a slightly sharper picture - it is however much worse at coping with changing lighting conditions and handling bright skies and dark foregrounds.

The Contour+ looks promising but given all the problems they've had with its predecessor, I would hold fire for a while until some user experience can be assessed.

Well my plan to get a contour has been put on hold by the sudden available of Bestival tickets ;)

Still tempted by the Poseidon though.

I bought a bullethd from hedcamz, used to have a cheap bullet camera, but this is much better. Picture quality is really good and its that light, you dont know its there. well worth it for the money.
