Well, with all of the hoopla about the 7D having the ability to shoot different frame rates
like 24P and such I guess it would only be natural folks would start asking how to shoot
24P on the 5DMKII, well unless Canon gives us a firmware update, and thats less than likely,
but for those of us that still see advantages to having a full frame camera, there seems to
be a very easy solution.

Its called Twixtor... here's the Tutorial on converting 5DMKII 30P footage to 24P footage.

Frame Rate Conversion with Twixtor : RE:Vision Effects Tutorial (http://library.creativecow.net/articles/freitag_lori/twixtor-frame-rate-conversion.php)

enjoy... I can't wait to try and convert the 30P footage to 60P footage...

You're late to the party, and this isn't really a substitution for real 24p because 30p simply just doesn't convert well. Also, I'm not sure what the point of transcoding 30p to 60p would be? Seems kind of pointless...

I'll have to try Twixtor.

Right now I use Shake and yes 30p DOES convert to 24p just fine.

Bill, I had purchased Twixtor awhile back to do time mapping. At the time all of my cameras shot interlaced and I never did get the results I wanted do to having to convert from interlaced to progressive prior to using Twixtor... but now with the 5DMKII footage
being great progressive footage, Twixtor works fantastic with it. I just want to take a
30P footage and overcrank it to 60P for a slow motion experiment. I have heard some folks
are overcranking to 120P and getting good results. :-)

I don't doubt that. Just check out the 7D overcranked to 240 fps using the same technique.

Frame rate conversion is hit and miss. Water is pretty easy, since who is to say exactly what the shape of the water should have been.

The tough challenge is when you have well-known shapes, like cars - especially with motion blur. Very small errors are really noticeable, even at full speed.

24/25p would be really welcome. Shooting native frame rates has perfect accuracy and takes no time in post. No software can compete with that!
