Hi,

Despite having read several how-to articles and viewing the archives here, I am still a little unclear on how to make best use of the HVX200's variable rate feature.

What I have done successfully is the slow motion feature that's described here:

http://www.studiodaily.com/studiomonthly/tutorials/trainup/5993.html

First of all, is that generally considered the correct setup?

If so, what's the best way to handle something that I might want at normal and slow motion? For example, a skater coming towards the ramp should be at a normal frame rate but on the jump, I want to use slow motion. Would I shoot all of it at the faster rate described above, use that directly in the 24p timeline for the slow motion part and convert the rest the clip to 24p? That is what I assume, based on reading this section of article on the History Channel shoot:

---------
O’Brien added, “The most useful feature of the camera was its ability to shoot 24 or 60 frames for any particular shot. Having 60 frames to use as a slow motion shot in a 24 frame timeline was the closest I've come to the days of 16mm, where you could dial up to 72 frames for slow motion. The 60-fps shots can be easily converted in Final Cut Pro to 24-fps if we decide not to use the shot as slow motion. Knowing this, we were unafraid and shot anything that we might want to be slow motion at 60 frames. This gave us a freedom we would not have had on film, where a slow motion shot would be expensive to convert back to normal.
---------

Just writing this down is making me think more clearly that this is the best path but opinions would be much appreciated.

Regards,

A few notes:
If you want sound on the recording you have to use 720/24p and not 720/24pn.

If you want the shot to be able to be played back at normal speed without motion studdering 48fps is better than 60.

:( SloMo also affects the exposure, so take care about changes in the image light and texture

Dont' feel bad, I have the same questions.

And I don't think you have to do 48fps. Just because that's double, doesn't mean you can't shoot 60p and do the same thing.

If 60p plays at 24 fps in the same timeline, then I'm assuming it'd be fine.
