60p from a bicycle with a consumer HD camera?
Hi,
I’m looking to shoot some 60p HD footage from a moving bicycle on a consumer camera (say, less than $1500). I’d like the stills to be as sharp as possible – given that I’ll shoot daytime in bright sunlight, a high shutter speed shouldn’t be a problem. So I started searching for camera that can record 720p60 and came up with this list: -Toshiba Gigashot K40H/K80H -Sanyo Xacti HD1010 And uh, that’s it. Am I missing something? I went to a few stores and shot test footage on both, mostly by just very quickly panning the camera back and forth by hand to get an idea of how good incoherent frames look. -The K40H doesn’t seem to have a manual shutter speed setting. By forcing the lightness(?) setting down (bottom right icon) to -5 (I think), it seemed to crank up the shutter speed. But the images still had a lot of blur in them. The specs say the shutter speed goes to 1/4800, but I don’t have any way of testing how it works in good outdoor light. -The HD1010 has a shutter priority mode, and the still images weren’t excessively blurred (though not as sharp as I’d like), but the compression artifacts were pretty horrible. It was hard to tell with hand-held shots, but there seemed to be some shearing distortion in both cameras, which I take is the rolling shutter effect? Panning seems to be a worst case – any idea how bad forward motion will be? The K40H is dirt-cheap, so I’d love to be able to use it, but I just don’t know if will produce good results. Anyone have applicable experience with it? Am I asking too much in trying to get high quality full-motion 720p60 out of a consumer camcorder? My other thought was to maybe shoot 1080i60 and downsample fields (ie avoid de-interlacing) to 540p60 or perhaps filter a bit to 720p60. Any idea if that would work well? I was thinking of going Canon HV20 or HV30 or HF10 for this, but don’t have any idea whether HDV or AVCHD is better for avoiding compression artifacts with incoherent frames. I did some 1080i test shots with the HF10 and wasn't incredibly impressed with the compression, but don't have any way of testing an HV20 or HV30... Thanks for any guidance! |

You could shoot at 1080i on something like a HV30 and extract 720p from that. Your bigger (much much bigger) problem is getting decent footage from a camera mounted on a bicycle (god knows I have tried everything) - if the camera is not shaken clean off :) even on - what appears to be - smooth road. Expect the footage to be poor to unwatchable, regardless of how pristinely you have captured this unwatchable footage. I recommend against a HDD camera like the HF10, the unavoidable shaking with almost certainly force it to park it's read/write heads - this is what happened when I tried this with a JVC Everio HDD cam. Your best bet will be to employ some type of helmet cam as your neck/head will act as a steady cam - coupled with on board camera optical or electronic stabilization - and possibly some post stabilization/tracking you can get a decent picture. |

Thanks for the reply!

I actually have a helmet cam now - it works great. The problem is that it is 525i and just doesn't produce enough detail. But having it on my head produces reasonably stabilized footage - definitely good enough for my purposes. Is there some reason that an HD camera needs to be stabilized more than an SD one? I was planning on jury-rigging a helmet-mounting for the HD camera too... |

You going to have to do some jury-rigging with the cam.I film a lot of motorcycle racing and mounting the camera on the bike is awfull.You will however find that a handy cam rigged to your helmet gets very heavy after a short while.I now use a helmet cam for this,however the quality is not as good as you are looking for.

What kind of videos do people shoot from bicycles?
I'll suggest using a very fast shutter and then stabilizing in post with tools like "Deshaker". You should probably avoid a CMOS cam for this application. |

It is amazing that you think you have just floated over the smoothest piece of road laid down since the invention of the wheel, with your super smooth cycling style and have just captured a steadicam like piece of film - only to watch back footage that looks like you forgot to put tyres on your rims.

Best possible cycling footage from a bike without anything exotic like having a steadicam strapped to you . . . ++++++ Small good quality HD cam strapped to your head (your body's steadicam). Image stabilization switched on - preferably optical image stabilization. Wide angle lens, this makes a huge difference !! Practice technique to see what gets you the best results. High shutter speed, higher the better. Stabilize the footage in post, there are many good and cheap (even free) footage stabilizers out there. |

Footage of the road ahead, other cyclists on bike rides, tricks and general bike fun !

You do see the rolling shutter effect on very past panning shots, but you would be surprised at how unintuitive it actually is. |

It's not a HDD camera it's a HD, quite a difference. It records on SDHC memory cards.

I shot the majority of the moving shots in this from a bike. 480i60 from a VX1000, and one from a VX2100. edit: Anyway, I don't think that you're going to get anything too great out of a cheap(er) camera shooting 60p. |

It's tough to get a smooth shot from a bicycle...you need a unicycle for that :)
