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!

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.

It's at 1/48.

This is the hardware thread Patrick is referring to:

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.
