Crumplepop<\/strong><\/a> have put up this excellent little tutorial which shown you how to get the equivalent of 1000fps by using Apple’s Motion and the Optical Flow in it. They were inspired by Oton Ba\u010dar\u2019s superb BMX videos which he used the plug in TWIXTOR on, you can see those at the bottom of this post. I don’t normally post other people’s tutorials directly but this was too useful not to share with as many people as possible. <\/strong>Do check out Crumplepop’s website for some superb plug ins including “shrink ray” for tilt shift effect in FCP.<\/a><\/strong><\/p>\n

This is from Crumplepop<\/a><\/p>\n

We were inspired by Oton Ba\u010dar\u2019s <\/em>incredible<\/em><\/a> <\/em>bmx videos<\/em><\/a> on Vimeo to experiment with retiming 60fps video shot on the Canon 60d. Specifically, we were interested in whether an obscure feature of Apple Motion called \u201cOptical Flow\u201d could achieve results that were comparable with Twixtor.<\/em><\/p>\n

After a lot of experimentation, we came up with a workflow that yields pretty solid results. As is the case with Twixtor, Apple Motion handles some shots beautifully while other shots get turned to ripply mush. Which is better, Motion Optical Flow or Twixtor? It seems to be more or less a draw, with Apple Motion having the distinct advantage that it comes bundled with Apple Final Cut Studio and is therefore free if you already use FCS. Either way, you\u2019ll need to pick and choose the best bits with the smoothest motion and the least mush.<\/em><\/p>\n

For our test, we used a Canon 60d with a Tokina 11-16mm f2.8, 59.94fps 1280\u00d7720, shutter at 1\/1600. It\u2019s important to mount the camera on a tripod, turn off AWB, and pick a scene with a relatively simple background (like\u2026snow).<\/em><\/p>\n

The basic workflow is to 1) Shoot at 59.94fps 2) Bring the footage into Motion and retime to 15%, 3) Export from Motion and conform it to 23.98fps using Cinema Tools. Then bring into FCP and edit.<\/em><\/p>\n

Here is a tutorial that shows the nuts and bolts:<\/em><\/p>\n
