I wonder if you could take the effect you're using. Say at 4fps or 8fps then in post slow the shot down to stretch it out to normal speed?
No problem, just shoot 720p mode instead of 720pN mode. It'll give you the exact effect you're looking for, at realtime playback, and with the added bonus of recording sound too.

Don't know the exact answer to that. When I put in "15", it comes up saying 24fps, same as when I put in 14. Is it truly 24? Is it 25 just named 24? I don't know.

But this I do know: if it was 25, it probably would not be PAL-compatible 25. The crystal in the HVX is designed to generate NTSC-compatible frequencies, which means 23.976, 29.970, or 59.94 frames per second. The PAL camera delivers 25.000 and 50.000. And the frame rates are not the same between the two cameras even when they're named the same. For example, on the PAL camera, 12 fps actually runs at 12.500. But on the NTSC unit, 12 fps is 12.260. Dividing the crystal clock by various frequencies results in different actual frame rates, and it does make a difference.

So even if it said 25, it wouldn't be "real" 25 because the unit doesn't have a PAL-compatible crystal.

As to whether the 50Hz/PAL camera can use "14: 24" or not, I thought somebody on the other forum said it did. But if it does, I would be flabbergasted if it was 23.976 actual frames per second, instead I'd bet it'd be something like 24.21 or some other approximate rate, just like all the other frame rates are.

Any idea when the bandwidth will be back to allow d/l'ing?

Thanks, Mark

Wow -- that went fast! Unfortunately that server will have to wait until June 1 to come back on-line. I'll try to move the clip to a different server to get it viewable again...

EDIT: okay, it's back on line, at:
http://hvx200.moctel.com/Users/Barry...Strip-2fps.mov

I can't edit the first message, so Chris or other wranglers: could you please edit the first message to point at this clip?

At lower framerates more light hits the chip for every frame, so the noise can average out much more.

Finally got a chance to see the clip.

Pretty cool!

I recall doing something similar as a senior in high school in a friend's car with a Beaulieu movie camera running at 2 FPS. Didn't look anything like this, tho. We didn't have such extravagant lighting where I lived.

Barry... While in Las Vegas at NAB I saw what looked like a news car with an industrial video camera attached to the hood with a suction-cup setup, pulling a u-turn near the Stardust. That would have been useful for this task.

I understand that :) even running slower shutters on the DVX100 makes a huge difference to noise.. as for the HVX, someone else posted a night shoot out on the town which was only @24fps that too was remarkably clean

Thanks Barry! That was way cool and it's exciting to see even more possibilities! Makes me want to go shoot!

By the way, I was going to print all of that out but I figured it'll all be in the book, right? ;o)

May be the question has no sense...but. Is there anyway for to shot at 80 or 100 fps....a firmgrade upgrade by example? or there is a hardware limitation for that....Just to ask....and lookin' for an extreme slomo....One more: What is the best way for to get a god B&W?....In post? or directly from the camera? Any tips about?

Thanks

60fps is the maximum rate.

As for black & white, you can't get b&w in-camera, you'd have to do that effect in post.
