Strange Vibration in Footage During Playback

[Bret Williams]

If the camera were shaking, the camera’s LCD should produce a non-shaking image to a certain extent if you think about it. If you’re looking at someone on a stage through a viewfinder, and the camera shakes ever so teeny tiny, the person you’re looking at would remain static, while the camera moves around. But then, play it back on a non moving monitor, and the image is shaking.

Just a thought if it is some sort of nearly unnoticeable vibration maybe that’s a possibility.

Hi Jeremy.

Here a link to the footage. I know the aspect ratio is off, but you still can see the vibration.

And Thanks for all of your assistance!

Best,
Jason

Looking at your sample 5 sec…Interesting. It has the look of a vibration from the floor, possibly from a machine or from foot traffic. I can’t say that it looks like a video signal problem. I wish I could see more detail in the background. Five seconds of higher quality footage on YouSendIt might give us more to look at. I have only used SmoothCam for this type of thing.

I agree, Tom. It looks like vibration from the floor specifically from foot traffic as you can kind of see a bit of a pattern to it. If you were completely zoomed in, any little shake can be picked up by even the slightest of movement. If you could post a few seconds of the native material in a DVCPro HD Quicktime, it might be easier to help and tell what is going on. Smoothcam might not help in this situation, but AE might be able to help. I don’t know though, this is a tough one due to the nature of the shake and any resulting blur (but that’s hard to tell on this compressed movie). ALso, if you don’t have hours to wait while SmoothCam analyzes your entire movie, simply export this five seconds as a self contained movie, reimport to FCP and set Smoothcam to analyze on that 5 secind clip and that will at least tell you if Smoothcam is going to work. If it does work, then you can leave it on overnight on all of your jittery footage.
