1080i/24pa footage "wobbles" on lines.

[cur-sed_neil]

anyone know why my beautiful HD footage "wobbles" whenever i pan something that has a horizontal line. like the top of a fence or the eve of a house - these straight lines wobble. everything else is fine, but the areas of the footage that has these lines wobbles.

??

it does it in the computer and also when i burn it onto a dvd.

my settings are default F6 - recording to P2.

i compared it to my dvx100a and the dvx doesn't wobble the lines.

thanks in advance!

Without seeing an example of what you are refering to it's hard to say for sure. But, I would wager that it has something to do with the speed at which you are panning. When ever shooting 24 your pan speeds are governed by set times... especially if you are not following action and just panning for the sake of panning. I believe Barry makes reference to this in his HVX book. You might want to take a look.

One other thing to check. If shooting off a tripod make sure your optical image stabilizer is turned of.

it's not the speed of the pans. it's actually anything "moving" in the frame. so if the shot is static on a tripod, and a person walks toward the camera, edges of them wobble as well.

i have shot 3 feature films (each on different cameras - but none HD) and i have never seen this before...

perhaps this is a higher rez trade-off and something i am going to have to live with.

OIS is off.

Hmmm.

What's it look like when you play it back off the P2 card in camera?

wobble is there.

Can you post a few seconds so we can see it?

Are you editing in a progressive timeline? If you are treating the material as interlaced, odd things can happen.

It's probably an interlace flicker. The horizontal line is fine enough detail to be on only one scan line, so when the interlace fields switch back and forth, it's there for one field and not there for the next, and so on, thus creating the flicker.
