View Full Version : Step by Step Overcrank

I have a G-5 Quad 2 gig RAM with FCP 5. I am trying to get the
slo-mo look on my clip that I shot with my very new HVX 200
camera - Recording format 720P/24P
Recording framerate set to 60 fps
Scene file - film cam

When I bring the 60 fps clip into an FCP timeline of 23.98 fps I must
render the clip of course but it barely seems slower - not like what I have
seen done by others online applying the overcrank method. I have tried to
apply a Modify - Speed change - sometimes the timeline freezes - I only have firewire 400 maybe firewire 800 will do better when I get it. Is this
the way to get the overcranked real slo-mo with HVX 200 and FCP?

If I bring the clip into an FCP timeline of 59.94 fps it doesn't need to be
rendered of course and if I slow -mo it through Modify speed change
it also doesn't need rendering. It looks like I want it to look but with frame blending. But I want to understand why the 23.98 fps doesn't work like I think it should.

Could someone write the necessary steps in order for both camera and
FCP to get the slow - overcrank look.


Also with the P-2 card files ( .mxf ) from the HVX 200 camera, when you go to trash them, many are locked. Is there a more efficient way than going to each and unlocking.

Your doing the process entirely wrong, first you have to shoot with the PN setting on the camera if you don't want to do any reverse telecine procedures... then you can bring them right into the FCP timeline.

If you have a native 60p clip, you need to take it into cinema tools and convert it to 23.98. (batch conform)

then go find it and reconnect it. then it will look fluid..

does that help?

If you shot 60p, then you use the DVCPRO HD FRAME RATE CONVERTER to convert that to 23.98 slo motion. It is very smooth.

Yea, and I have done this many times in cinema tools as well...

I appreciate the help. I am getting a better idea of the
the different possibilities. I just used the frame converter - great tool.
I'll try Cinema Tools.
Thanks

Any way you can get normal 24p from a 60p source? I would like to do a normal speed to slowmotion shot- like a guy running, then suddenly a guy aproaches for a punch, in slowmotion- all in the same shot!

Use the Time Remap option. Slow your footage down then use time remap to speed it back to normal, then gradually slow down.

Thanks, Shane. very nice tutorial! However, I can't do this in a 24 or 25p timeline, right? I need to do this with a 60p timeline. Can cinematools convert 60p to 24p and maintain 24p normal speed? (No slowmotion effect?)

Just drop the 60P footage into a 24P timeline and render. It looks fine. Or get the Standards Converter from www.nattress.com and use that. Same result though.
