How many Gs (force) can a DV camera handle?

How many Gs (force) do you think can a DV camera handle for let's say a roller coaster or a bobsleigh run?
Has any one filmed a rollercoaster run POV with good results (in dv) ? I tried it years ago with a hi8 but camera and tape did not like it....
 
how many G's can a dv camera take without the tape moving from the video head creating snow and distortion like my hi8 camera did years ago during a roller coaster ride?
I dont need to know exactly how many g's a dv camera can take but basically i want to know for instance if you were going through an intense roller coaster, will the image be fine and stable, unlike hi8?
I think what happened witt the hi8, that due to the gforce, the tape left the video head in sharp turns and my question is would dv do the same?
I would like to do a pov in a bobsleigh run...
 
I remember awhile back a few guys strapped one into the tip of a "missile" and dropped it out of the plane at about 30,000 feet and let it drop. I think the resulting film was called velocity or something similar.

I'm sure that had some force on it. They just used cheap sony dv cams I believe.
 
Edweirdo, that's exactly what i wanted to hear, altho these cameras go with 512mb flash card, seems a little small for an entire bobleigh run which i guess takes about 2 minutes?

Yes, it did have some force to it: 1 g. :cheesy:
 
I've personally pulled about 3 g's and a friend of mine does a little more than that.
Dependds on what you are trying to do. The camera should handle more than people.
If, however, you are changing G forces from positive to negative in irratic fashion, that could cause a problem for both.

Thinking about it, it might be ≤1 G. Not sure of what forces are actually present in "freefall".

But it won't be greater than 1 G....until it hits the ground. At which point, the tape lifting from the head is the least of your worries. :grin:

Hmmm....anything causing deceleration will increase the "G" force (in a negative direction), so a parachute opening will do it, too.
 
dv cameras handle shutes opening hands down, bobsleigh and roller coasters are a different story i think.

with this cam you can add a memory stick, and those go up to like 2 gigs or something, and thats PLENTY for mpeg4. You should get at least an hour for that.

In freefall, you experience zero G. Because the gravity is actually accelerating you, it is "forceless". The only forces you experience are because of aerodynamic drag, but they like you and your flapping suit mch more than your streamlined camera ;)
