Nice work, Jack! Now that you've learned so much about conversions (and graciously shared them with us), are you planning to shoot a true 24P project?

Already did :) Almost entirely 24p and almost already all in the can (one scene to reshoot and a couple of pickup shots)

Great shot and stunt at the end. Have really enjoyed these posts on the making of this, it should inspire everybody to just go out there and shoot.

Thanks Adrian. That's the idea hopefully.

I have to get to updating workflow info. Basically I wound up preferring drop frame telecine (drag and drop 60p onto 24p timeline) for frenetic motion. I'm doing a slight variation but it's basically drag and drop.

For subjects that should be moving super smooth - like the cars in the frame rate test - use one of the interpolation or frame blending methods in the frame rate conversion tutorial.

But for frenetic motion, like a guy waving his arms wildly and running around a corner, drop frame is better. Why? Because his hands turn into all sorts of weird Dali painting type hands with interpolation or double frames if you use frame blending. Also since the motion is irregular, drops in the cadence will be much harder to notice than with a smooth gliding car.

So for non glass smooth moving subjects the 60p dropped onto a 24p timeline is smooth enough and has none of the weird abstract frames that can occur on such movement with interpolation and none of the double framing from frame blending. Again, if it's a car or a skateboarder or a canoe, use interpolation or frame blending. 2 reasons. 1 this is where cadence breaks will show and 2 interpolation is based on guessing what happens between frames. For a constant speed object it does well. For Elaine (from Seinfeld) dancing, an epileptic fit, or any other irregular movement, use drag and drop or my slightly modified method.

... ok so what is my modified method - well I'm not sure it's doing anything different than drag and drop and if it is I'm not sure what but it I THINK it looks smoother. Basically I'm slowing the 60p down (conforming to 24p) then speeding it back up to 24p but with no interpolation or frame blending. This means it has to drop frames just like dragging it onto the 24p timeline without ever changing it's speed in the first place - but which frames. I think different frames with a more regular cadence when I do the slow down, then speed up. But I could be totally imagining this. I have a test in mind that should show which frames are being dropped. Who knows when I'll get to it though.

Wow! That's super cool. I can't wait to see BTS and footage!

Thanks for the breakdown. Given what I've seen from your tests your methodology makes perfect sense. I had a much cruder methodolgy in mind, but I think I'll adopt yours. One question though, just to be clear, you're shooting your 60P for 24P stuff at 1/60 shutter?
 
Well I should have been shooting 60p with a 1/60th shutter but I messed up and shot 1/50th. Which forces the camera into a hacked 30fps in a 60p wrapper. So this is as jerky as things should get. If you stay at 1/60th or above it will be smoother. I did it wrong in other words. The short is AVCHD 60p (hacked to 30p in a 60p wrapper, or double frames in other words) and MJPEG 30p mixed together on a 24p timeline. The only AVCHD 1080 24p is the family in the courtyard.
 
hey i saw the first half like a month ago and i was always wondering how this would end.
looks like a pipe just doesnt compare to a machete ;)
lol i really like this short it was cool
but there was some jello but i guess thats something you should expect from a small dslr camera

For cereal? Where? In the whip pan?

Let me know where you're seeing jello other than the whip pan, because I don't see any. It's is very minimal with the cam. General consensus goes D90 (worst), MII (better), then GH1 and Red are about the same level of Jello, which is almost none.
