View Full Version : avoiding vertical judder during fast pans?

hi all -- so i'm shooting a project on the GL2 that necessitates the use of moderately fast pans.

i grew to like the look of frame mode at high shutter speeds for this piece, but then i noticed the awful judder artifacts that appear on virtually every vertical line in the test shots during playback.

the pans have to be fast -- no getting around it. i'm willing to give up frame mode if it means losing these judder-horrors, and i'm wondering if i can avoid them by shooting in normal mode and then deinterlacing in post -- or will this process introduce more unslightly motion artifacts during my fast pans?

(thanks for any advice -- i'd test it myself but i'm getting only one more chance with the set and the gear, and that's during the imminent actual shoot!)

Many folks like frame mode because it looks more like film. But film does not handle fast pans or other rapid camera movements well. You get a judder or strobe-like effect thanks to slower frame rates, and shooting video using the same parameters can give similar results. Maye add some blur or smear to the pan to mask the artifacts.

Run some test tests what works best for you.
