XHA1 24F is "Jumpy"

Hey all,

I do alot of compositing with my XHA1, if you've read my previous post, I'm having a bit of a hard time getting the footage off the camera, but that's another story!

My question here is, since i GOT the footage off and onto the CPU my 24F footage feels like I'm missing frames. I usually shoot 30F but decided i want my stuff to look a little more film like. I don't have a red rock setup or anything like that yet, but at least 24F will help for now.

I shot footage of moving bus' in Santa Monica and it feels like it's just not right, the motion feels a little "sped up" and the vehicles seem to "jump" or "skip" along the road rather than smoothly drive.

Here's a link to the shot, please let me know if anyone knows why this might be the case.

When i went back to look it seems the cars at the end are most jumpy, and the footage is sped up i think, otherwise it's not HORRIBLE by any means but looks WAY different than 30F.

Thanks again in advance!

-Pat

What was your shutter speed at?

It looks as if your shutter speed was too slow. If you're shooting 24 fps, it needs to be at 1/48.

This is the hardware thread Patrick is referring to:
http://www.dvinfo.net/conf/showthread.php?t=116803

I think the first step is to play the raw footage directly from the camera and see if you see this anomaly. If so, it is a camera issue...but I'm going to guess up front that nothing is wrong with the camera and that it is a computer issue, as the other thread would tend to suggest.

Assuming the raw footage from the camera plays properly, do you have access to a system that is known to have worked properly (your previous system or perhaps a friend's)? If another system will capture and edit the footage properly, well, the most straightforward solution is to back off of the unsupported Vista 64.
