New GoPros do 60fps but that’s still not fast enough if you want that high speed camera look. You can slow it down in editing and blend the frames with “optical flow” in Final Cut Pro X but if there is lots of movement it makes it look like shit is melting and ruins the footage. I’d say at least 120fps or more for what you want.
I’d look for something at 120fps or more. 1000fps would really do it.
You can slow the frame rate down with a Twixtor plug in too, but it acts the same as Optical Flow and can create some weird effects that won’t really show the deflection since its digitally replacing/repairing/blending frames that aren’t there to begin with.
I used Optical Flow on the video I did of my car last year, you can see how it distorts certain parts of the footage. Notice her inner thighs as she’s walking towards the car, it looks like liquid. I think I slowed this down to about 5 or 6% of its original speed too: [ame]http://youtu.be/eFAzQiuwn_A[/ame]
Depending on how much resolution you need, it’ll burst 6 megapixel still shots at 60fps, do 300fps video at 512X384, 600fps at 423X192, and 1200fps at 336X96. It also can do anything between 30 and 300fps at higher resolutions.
Its a few years old, so I’d imagine there’s a new version out that’s even better.
