Bird slomo with the 7D's 60 fps

Just trying some bird slow motion via the 7D's 60 fps HDV capture. Here's a pair of Zebra Doves (Geopelia striata), filmed in habitat under sweet early morning light. View in HD if you wish to see how feather detail is resolved.

Gear used - Canon EOS 7D + Sigmonster (Sigma 300-800 DG) + Canon 2x TC, 1600 mm, f/18, 1/125 sec, ISO 320 - 640, Manfrotto 475B/3421 support, captured in 720/60p and overcranked to 720/24p in post process (40% of normal speed). All clips were captured at Paranaque City, Philippines, on November 1, 2009.

Just for kicks, I took one short clip from the above series and slowed it down further to 20% of normal speed. The original 60 fps capture became 12 fps and I used software interpolation to bring it back to 24 fps.

Thats really nice Romy liek it slow as you get to view the detail a bit longer.
Rob.

very very nice!

that term is being used in a wrong context. overcrank is to increase the framerate from ordinary framerate such as 24p, 30p, or 25p to much higher frame rate like 50p, 60p, 120p, etc...

The term "cranking" is originate from back-in-the-days when they ahve to manually crank the roll of film by hand to capture motion.

That's pretty cool. But very boring to watch for more than 20 seconds. Maybe have the birds explode in the very slow version after about 30 seconds.

no offense but if you're to prove someone wrong, at least read it first.

I'm not so sure what your point is, but check out how Philip Bloom, a well known filmmaker, used the term "overcrank":

"Filmed on a prototype Canon 7d in 720p 50p mode then converted to 25p using cinema tools to get overcrank."

not to make it a big deal but i believe you meant to say that the footage was overcranked to 60fps and you slowed it down to give a slow-motion. you didn't overcranked to 24p but may have imported into 24p timeline, and thats a wrong context. I'm not trying to belittle you or anything, just want to point that out since this is a photog forum.

Please don't link ppl wiki that way again bc thats an insult.

LoL. Phil Bloom is not a well-known filmmaker, he's a internet sensation. He's well-known w/ testing various 35mm adapters and other camera gears.

Ok, I think we both understand that I got a slomo by shooting at 720/60p and playing the footage at 720/24p. If you think I used the term "overcranked" in the wrong context, you're free to do so.

Trey T is right. But lets get back on track here. Great bird stuff. What software did you use? After Effects?

I was hoping the 1DM4 would have native slowmo you see in prosumer camers like HVX200.

Overcrank - Shooting faster than normal frame rate for slow motion effect

Undercrank - Shooting slower than normal frame rate for fast motion effect.

Think about cranking an old film camera. If you cranked it too fast, the playback would be slow. If you cranked it too slow, the playback would be too fast. Assuming of course the playback was constant.

Lovely images and music but I'd really like to hear just a little ambient sound mixed in.

Nature doesn't exsist in a studio .. It's outdoors.

Spectacular!!!!

Congratulations

Trey T is correct. You overcranked at the taking stage by filming at 60fps as opposed to 24fps. You enhanced the overcranking effect in PP by reducing the playback speed to 12fps and interpolating the missing frames, but that process would not be referred to as overcranking.

As others have already said, the term originally comes from the handcranked cameras of early film making days, which relied upon the cameraman cranking the film through the camera manually at a steady rate. This was required to be as close as possible to the intended playback speed to avoid the finished scenes playing back either too quickly or too slowly.

Undercranking was often used deliberately during filming so that the playback speed appeared quicker, typically used in chase scenes - think Keystone Cops.
