Twixtor Pro Tutorial - How to use Track Points in Twixtor Pro (720p)

In Deutschland ist das Video leider gesperrt, man kann es sich jedoch auch hier ansehen: http://vimeo.com/24571687

Following some requests concerning my recent video showing extreme slow motions created with Twixtor Pro I decided to make this tutorial about how to apply Twixtor Pro and especially about how to use Track Points in Twixtor Pro to avoid ugly blending ghosts and artefacts.

I used Premiere Pro CS5 but I think the steps are similar in other video processing software packages like After Effects, Sony Vegas, Final Cut Pro etc.

For further information about the original video (settings etc.), look here:

I hope this tutorial is helpful to some people. Enjoy and leave comments!

how come you only use 2 frames, would it have been different if u want to use 3 frames? and is there a way to calculate what speed i have to use?

For example, i want a 25 frames long sequense to last 3 seconds instead, but my project is in 60fps. So 3sec is 180 frames and if u duplicate my 25 frames 7 times i get 175 frames, so what will happen to the last 5 frames? and how do i calculate what speed i need to use on twixtor

Thanks for the tutorial =)

Of course it would also work when you use 3 frames instead of 2, but because at such a slow motion (less than 1%) and such a fast shutter, you will get serious blending problems and the result will look really bad.

Your calculations are right. Concerning the remaining 5 frames, you could also duplicate the 25 frames 8 times and in the end cut off the surplus part which you don't need in the final result.

after you applied twixtor to your video, you rendered it to show us. But after that when you went into adding tracking points, i noticed that your video was not rendered. Would it be best to render once we have gotten all of our tracking points in and when all the settings are how we want them? Or would it make the process go smoother/faster if we render after applying twixtor to my video and then again when everything is complete?

As far as I know, rendering before adding track points won't give you any advantages, because as soon as you add track points after rendering, any previous rendering is abolished and you have to render it again anyway (at least in Premiere Pro and After Effects). Moreover, when adding track points, you are working with the original (not-twixtored) footage to see each single frame to allocate each track point to its certain locations.
