Hi Lee!
You did post the wrong link, it leads to the original footage. This is the right one:

Whoops ! + Thanks for spotting that !
At first sight it looks perfekt. But watching the legs of the man leaving the frame of the first shot you can see an odd movement, his left leg is literally jumping out of the frame. The same happens in the second shot, when the last girl of the group of three enters the frame. The right girl of that group also makes an odd movement when her right leg is passing along her left leg.
As I understand it, it is difficult for interpolation software to interpretate objects that enter or leave the frame or that get hidden by other objects inside the frame. Some programs allow you to mask such objects (like Twixtor) to "explain" to the software, where they come from, where they are and where they go to. But doing so in every situation would suppose a heck of additional work, I suppose.
Said this I must add that, in this footage at least, these are minor flaws I could live with. And thanks a lot to you, Lee, that you postet this example, I was waiting a long time for something like this and I hope more converted footage will follow because it might become a very important workaround with the 5D.
Good points, quite subtle temporal artefacts, but still there.
I tried going from 60 frames to 100 frames and then back to 50 frames (so 2 seconds NTSC to 2 seconds PAL via 100 frames) - but it looked no better than simply going from 60 frames to 50 frames without first converting to 100 frames.
Bear in mind I just hit 83.333333% on the footage length and switched frame interpolation on - I did no other work.
In the Timewarp plug-in you have much more control and - as you say - Twixtor also has much more control, so maybe with some good settings even these slight temporal glitches could be addressed ?
To be honest I didn't even notice them untill you pointed them out and I had to watch a few times to see what you meant ! I guess I just have low standards !! :cheesy:
