this one is really good...
too bad he doesn't say what shutter speed he used

Regarding the shutter speed - it's fast. There is almost no motion blur.

This is an ideal use of tweening software. The edges are crisp. The foreground stands out from the background. The initial motion isn't super fast. (A hummingbird flaps it's wings much faster than a human can turn a BMX bike.) Also, the motion is consistent and smooth, not jerky.

I'm not criticizing the video or Twixtor. Just the opposite. It's good to know what the tools do well and to use them to their best advantage. There are no points for doing things that are difficult, only for doing things that look good. :)

sorry if it's been discussed already, but why doesn't Canon release a firmware to extend 50/60p 720 capabilities to the 5D?

Because it doesn't have the dual processor that allows it.

so which would be the ideal camera setting to shoot a scene that will have to be slowed down on Twixtor?
fast shutter all the way? I am very close to pulling the trigger on Twixtor

I find that for normal motion, 1/200 or faster produces crisp edges. Of course, it depends on the lens, the distance, and the movement.

Because it doesn't have the dual processor that allows it.Neither the 550D/T2i, the 600D/T3i nor the 60D has dual DIGIC 4 processors like the 7D but all are capable of filming 50p 1280x720.

Darn it, I knew I should have researched those cameras before stating that. Thanks for the correction, Nigel.

so still it's not clear to me why a firmware upgrade shouldn't be able to give us 60fps?

I'm pretty sure it's to do with the size of the sensor and the heat it produces making it impossible for the current hardware / firmware to cope with the heat (and processing) required for overcranking.

not even a 720 50/60p?

You would think Canon would have added 60p at 720 that when it added 24p, if it was possible. Certainly, it would have boosted sales on the more expensive 5D. Having followed the development of Magic Lantern pretty closely, including attempts to increase bit rates and such, its become apparent that the the processing chip in the 5D has hard limitations that make it not likely that a software resolution can be introduced. I am not a programming geek, but it seems likely that in the chip design for the Canon 5D, it can't be instructed to change over to 720p format. That is my guess.
