Hi everyone..
I'm working on a project that involves high speed shooting like in an example capturing an explosion or something like that. I was wondering if I can use my DVX102B camera (asia) for that purpose..if it is possible how do i do it?

Thanks

High speed refers to frame rates over the standard 24 or 30. The DVX100 cannot do this. You'll need a special high speed camera that, as far as I know, does not capture to a tape. The DV codec is limited in that it only allows 29.97 fps. I'd assume tape codecs are all limited similarly.

The HVX can capture higher frame rates, I'm not sure how high at the moment. Otherwise you'll need a special high speed camera to get the detailed slow motion shots

Actually you can. Shoot 60i with at least a 1/120 shutter speed, then add it to a 23.976 timeline and slow it down by 60%. Only half resolution but frame accurate slomo.

How do I shoot a 60i with my dvx100? Does it have any effect when i edit it using a 23.976 timeline when I'm living in Indonesia and the system in my country is PAL?

Thanks for taking the time to answer my silly questions..

PAL will do 50i instead. I noticed these guys talking about slow motion...but i didnt see that in ur post. Do u want this fottage to be slowed down (slow motion) ?? Putting the 50i on the 23.976 timeline will cause a drop in resolution but is the way to go with the dvx and slow mo.

I dont see why 24p at a higher shutter (120) cant allow u to get higher speed stuff (IF ur not looking to slow it down). The higher shutter will introducea more "choppy" look to ur footage especially if ur zoomed in, however in my opinion it is quite desirable to increase the intensity of the scene, that however is an artistic choice and some may not like it. I luv it :). Run some tests and see what works.
