XH-A1 slow motion test
 
here's a slow motion test we did the other day for a trailer we're making.
no audio on these clips, shot 60i, then slowed down in After Effects.

Let me know what you guys think.

Thanks

Pretty good! What shutter speed were you shooting?

Christian Nachtrieb February 4th, 2008 06:24 PM

Shutter was at 1/120.
Thank you

Excellent! That's probably the best job I've seen of anyone slowing down XH-A1 footage... I might just have to switch my system to Adobe...

what rate of speed is it at in AE? CS3? Any other special settings to make it so smooth?

I used After Effects CS3, all I did was import the footage, click on Interpret, and tell it to play back at 23.976 fps. You create a new comp with it, and then you do a Time Stretch, at exactly 200%. Then you click the option for your footage to "frame blend" I think it's called.. the solid slash is what you want, interpolation.

That looked sweet... Nice job After effects... : )

Yeah, it's a cool trick. I do the same thing in Vegas. I used it for my last feature, THE BROKEN QUIET, for a few shots -- beautiful indeed.

That was really excellent! I have a new EX1 to go with my A1 and your work rivals some of the overcranking I am getting out of it.

Does anyone have any advice for doing something like this in FCP? Am I going to need a pluggin?

Also what are the effect if you do this to your footage and speed it back up?

If you wanted to do slow motion in final cut, and make it look good I would recommend buying a program called "Twixtor."

To speed it back up is easy, when the exported footage from after effects is brought back into final cut, it's all slowed down. So all I did was break the clip in two, and change the speed of the first half to make it go faster, so it looks like it is running at normal frame rate.

There are better ways, like within after effects for example using time remapping, but I didn't feel like getting fancy.

Thanks.

How long of a process is this?

Nathan Quattrini February 11th, 2008 08:43 AM

so you madea 24fps comp, and exported 24 fps as well correct?

Christian Nachtrieb February 11th, 2008 10:31 AM

Not a long process at all.

Yes, after interpreting the footage as 24fps, I created a new comp that was 24fps and exported it as such.

Todd Smaretsky February 19th, 2008 08:03 PM

Looks good. I'd stay in 60i though - it would be more fluid. That is just my opinion. But, very well done.
