View Full Version : XH-A1 slow motion test
Christian Nachtrieb February 4th, 2008, 12:01 PM 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

Jerome Cloninger February 4th, 2008, 04:19 PM Pretty good! What shutter speed were you shooting?
Christian Nachtrieb February 4th, 2008, 06:24 PM Shutter was at 1/120.
Thank you
Nicholas Tran February 5th, 2008, 06:46 PM 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...
Nathan Quattrini February 5th, 2008, 11:01 PM 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.
Doug Davis February 6th, 2008, 02:58 PM That looked sweet... Nice job After effects... : )
Brandon Freeman February 6th, 2008, 04:35 PM 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.
Bryan Suthard February 7th, 2008, 12:35 AM 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.
Sam Haber February 8th, 2008, 11:53 AM 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.
Sam Haber February 8th, 2008, 12:25 PM 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.
Nathan Quattrini March 9th, 2008, 07:58 PM wanted to say thanks for your help, heres the first test I did with your instructions
