HVX 60p Slow Motion

Hey guys,

I'm sure this was covered somewhere but I've looked around and have not got a clear answer.

I am shooting a commercial next week that will need to be in slow motion. I own the DVX but am hear that the HVX's 60p is the way to go. I can get one for a few days on the cheap but have never ued one and will need to work fast.

So how do I import the 60p footage into FCP (5.1.2) properly? To get ultra slow motion should I edit using the 24p timeline?

I can also get the HDX900, is there a point? Would it be better for this shoot?

Thanks
 
To get slow motion in camera, you will want to shoot in 24pn or 30pn modes. Then, in your scene file you will set your frame rate above that. So, if you are shooting 24pn (@60fps), you will get 2 and 1/2 times slow motion. Remember that no sound is recorded in over/under cranking modes in pn. I believe you can also get slow mo in camera using the regular p or pa modes as well (not positive).

If you didn't do it in camera, you would do it in post with your NLE. In that case shooting 60p would be the way to go. You will get a smoother slo-mo (when doing it in post), if you have more frames to work with.

Hope that answers your question

That's very helpful thanks.

Out of the 2 (In camera or in FCP at 60p) which would you use?
Also, as far as importing into FCP, how would I approach either method?

Thanks alot for the direction.
 
I shoot 60p in 24pn and then dub it to tape, being that I work in SD. If it is going to end up in SD, save time and hard drive space and downres before importing.
 
I'd so slo-mo in camera, it's more clear, frame acurate, super easy.
In FCP, when you shoot with an alternative frame rate, do NOT use the pulldown on import, use the Frame Rate Converter after you've imported it to match it to the frame rate base of your Seqeuence.
 
One more thing - if you are shooting slow motion, remember to increase the shutter speed. If you don't increase the shutter speed, the rushes will appear blurred. Furthermore, if you increase the shutter speed, you need more light.
 
Thanks guys, that helped a lot.

One more thing, if I do it in camera can I shoot HD? Or is that option not available for those frame rates?

Sorry if this seems very "noob" but I have never touched the HVX yet, finding it hard to get rid of my DVX, I'm sure it'll be easy one I see the new footage.

What's the difference between recording VFR's in 720pn/30p and 720pn/24p. I've searched the Operating Manual and it doesn't tell you the difference.
 
Okay so I wasn't wrong in thinking:

720pn/30p @ 60 plays back 30p slow-mo. Which means you could potentially record 30p @ 24p and get this weird slow-mo together with 720pn/24p yes?
 
Each frame rate is capable of giving you three (to four) different looks.

If you record 26fps in 720/24pN, it'll be very mild slow-mo.
If you record 26fps in 720/30pN, it'll be mild fast-mo.
If you record 26fps in 720/60p, it'll be sort of filmlike, with realtime playback
If you record 26fps in 720/60p, strip out the duplicate frames, and play it back at 60fps, it'll be super-fast motion.

Some of the frame rates will look the same; 24fps in 720/24pN will look the same as 24fps in 720/60p, delivering the filmlike look in both (unless you strip out the duplicate frames in the 60p version, at which point it'll be 2.5:1 fast motion).

So you have about three dozen different frame rates, with about 4 different looks per, so you have somewhere around 130 different creative possibilities with the HVX.

You mean 720pn/60p, right? ... wow. There's a really good thing about 60p that I want to try out. I like the idea of regular motion with a bunch of frames within it.

Thanks for the explaination, Barry.
 
This is kind of along the same lines- any input / suggestions would be great. Here is what I want to do, let me know the best way to do it:

I want to have regular motion for the first part of the clip, then slow down to 2.5x, and then go back to regular motion. (Ala Lockstock and two smoking barrels).

So far I have attempted the following test-
Record in 720 60p at 60p.
In FCP take the 60p footage and put it into a 24p timeline.
Find the edit point at which I want the slowmo to happen, and using the razor tool cut at the start and end of the slow mo clip.
Then adjust the speed of that section to 33.33% at a constant speed. (This gives me 2.5x the legnth of the original clip.
Render out the clip.

Is this correct? Do I now have 24p slowmo in the middle of the clip? Is there another way I should be doing this?
 
Here's what I'd do. Import it as normal. Then use the Frame Rate Converter to convert it to 60fps and chose to save it out as an independent clip. Then splice the two versions together. I don't think it'd be all that tough to do. That way you have your in-camera slo-mo and your normal speed stuff, all looking as good as can be.

If you don't use the Frame Rate Converter, you don't have the alternative frame rate matched to your Sequence.
 
Thanks for the suggestion. I'm trying it out now. It took a little bit for the frame rate converter to work, for some reason it would not open / start at first. Now I'm just trying to play with the footage and get it sync'd correctly as I still have the first part of the clip playing back at 720 60p in a 24p timeline. The converter did a great job at making the 60p 24p for the slow mo section, Thanks!

33% is the wrong number, you want 40%.

That's what I originally thought- but when I put in 2.5x the number of frames it said that it was 33.33%. Although I was a bit confused, so I could have easily changed something inadvertently. Thanks for the correction.
 
I just got done testing it out, and for those of you who wish to do something similar, I would HIGHLY recommend using the frame rate converter, as it will give you much smoother results delivering cleaner footage. When I used FCP to slow down the footage (40%) and rendered it out, it gave me that stuttered slow mo effect common in slowed down, non-slowmo footage. Just an FYI.

Thanks Barry & Ben for your help. :beer:
