Can the AF100 do slow motion shots like this:







Thanks =)

Short answer......No.
Those kinds of frame rates are achieved with specialist cameras capable of frame rates above 500fps.
The Epic comes close at 300fps 2.2:1 sub frame.
The best the AF 100/101/102 can do is 60fps in NTSC mode, and 50fps in PAL. If you shoot interlaced 50i/60i then you can use something like Twixtor to create extra frames to achieve 75-100fps, but this is not always possible.

Can AE's time remapping do what Twixtor does? I tried using it and I got weird artifacting, especially in areas of movements. There might be some techniques to prevent that. Thanks Matthew.

Nope. Sorry. The fact of the matter is, your camera simply is not up to the job of super-slow motion. It just was not built for it. If you absolutely must have it, you'd need to rent a camera capable of shooting at high frame rates.

I agree with Dave.
These tools will work better with interlaced material than progressive, but there is no substitute for high frame rate capture in the 1st place.
And I have had more luck using Twixtor than AE for the times I have had to use it.

If you don't require HD, or very high quality at all, then there are some interesting little compact cameras from Casio that can do 1000fps albeit at a lowly 224x56 frame size. 420fps is better at 224x186, and 210fps at 480x360. Check out http://www.casio-intl.com/dc/ex_fh20/hsmov/ to see some examples.

Yeah if you really want to do it right- rent a Phantom for the day- amazing footage. Otherwise Twixtor from 60i/60p footage is your next bet. RED also has decent slow-mo but still not super dupe slow like the Phantom...

Can I use 60p footage from a 60D and then use Twixtor? Are all Red cameras capable of 300fps frame rate?

To get that super-slo-mo look in your example? No.




[clyde villegas] "Are all Red cameras capable of 300fps frame rate?"

I bet they'll tell you on the RED web site.
Again, if you're after that super-slo-mo look, you want something that shoots closer to 1200-2400 fps.

If all I'm after is the look of a 300fps slo-mo of the Red, will the 60i + twixtor combination work?

Progressive formats do not work as well as interlaced formats when using things like twixtor. Frames comprised of two temporally different fields assist the programs in creating new frames as the motion shift per part of second is less.
I mentioned before, the Red 1 can shoot at a maximum of 120fps sub 2K, and the Epic can do 300fps sub 2K.

I see. Can the 60D shoot 60 frames interlaced?

Nope. Full frames only, no interlacing.

Face it: for the best results you need to use the right tool for the job.

If you're doing woodworking and you want to turn a table leg, you don't attach a 4x4 to the back wheel of your car, gun it and start cutting. You get a lathe. Likewise, if you want proper slo-mo you get a camera that can shoot slo-mo.

What if you don't NEED the best results? Do whatever you'd like, and have fun!

60 fps will only get you part-way - and not the "super" slow mo that you see in the above video.

You can use a plug in like the built in TimeWarp, or FOundry's KRONOS to do flow-field time remapping - but me aware that you can really only "double" you fps rate before really bad artifacts come into play.

http://www.thefoundry.co.uk/products/kronos/examples/

THough this guy did a good job using just time warp to get effective 1000 fps:

http://nofilmschool.com/2011/04/canon-7d-1000-fps-slow-motion-surfing-video...

though it should be noted that WATER is one of the easier things to retime this way. Hard objects - like cars - reveals the artifacts clearly.


A lot of the material that was in the video above mostly looks to be in the 300 to 1000 fps mode.

As for 300 fps, not all RED cameras will operate that fast, and those that do typically have resolution limitations as well.

Here are pumpkins being smashed at 300 fps, then Twixter was used to make some of them 1000 fps:

http://cinescopophilia.com/red-epic-300fps-footage-slowed-down-to-1000fps-i...

Here is some 1000 and 2000 fps examples:

http://cinescopophilia.com/weisscam-hs-2-camera-vision-1000fps-2000fps/



The relatively cheap Casio EX-F1 goes up to 1200 fps, but the quality is fairly poor.

Though it appears not too bad at 300:

The Phantom is the bomb ... but even the rental fee is shocking.
