Moving Camera Yields Glitchy/Flickering Footage

Can someone tell me what is happening here? (password is "wtf")

60i / Shutter at 60 / everything Manual / stabilization off

Captured 60i via cineform. Exported to h.264 via adobe media encoder. Tried every possible combination of h.264 export settings.

Thanks for the help.

When you export to h.264, what is the key framing set to? default is 24, try setting it to 1 first. It will take much longer to render, but if that solves it, then try changing the key frame rate to 23 or go up to 30. I believe it's a render issue. does it do this with other formats?

btw, looks great, using a jib? what kind?

I don't know if this applies to Cineform and/or Adobe Media Encoder, but Quicktime defaults to keyframe every 24 frames & for the Animation codec, this would be correct. But for NTSC I've read it should basically be 10 times the frame rate... 30fps = key frame every 300 frames. It may be different for a h.264 codec though.

Just curious, why would you capture 30p with 60i footage? Why not just shoot 30f to begin with?

Thanks, guys. I'll play with the keyframes.

Adrian, when I exported to .wmv I did not have the issue. As for the jib, I'm using the camcrane 200.

Bill, I don't know what I was thinking -- I did capture 60i.
