He did say that it is visible on-camera and in the raw video, so it isn't a Vimeo issue.

I went to my local camera store and did tests one after the other . One with their display camera (old firmware), and one with my camera (new firmware). Same CF card, same lens and same tripod. Still got similar results.

Can anyone post a 'good' and 'smooth' example - just so I know it's possible?

thanks for you help.
cheers

Peter,

Wild guess here - but I've got 2 Manfrotto tripod/head combos and on both I've had 'skipping' or 'slipping' issues that are caused by the set screws underneath the head coming loose. I recently had this with a practically brand new 701HDV head that I use for my 5d.

There are 3 flat-head screws underneath the head (on the cast aluminum portion). I tightened these up and no more skipping. It just happened on certain pans, and tilt angles - certainly not consistently, but hearing you announce when the 'slip' or 'skip' takes place, it seems familiar.

thanks for the ideas.

Tripod is fine. Have also tried a handheld pan - same issues.
Also tried the lens twist idea - same issues.

any other ideas?

My next stop is perhaps Canon repairs / warranty - and see what they say.

cheers

Are you reformatting the CF card every time you shoot, or just deleting the old files? I've seen skipping on a card after file deletes, but never on a cleanly formatted card.

Thanks Al,
yep - re-formatting (almost) every time.

Hi Peter,

I haven't seen in the info you supplied which shutter speed you used. Wrong SS can cause this problem as far as I know from other cameras.

I have similar judder issues. I see judder on the cameras screen as well. Unfortunately, I am so new to video I don't know if it's me, the camera or software.
My pan/track judder video is here TrackPan_02 1/60 IS off on Vimeo

Hi everyone,

I don't post that often, but this just happened to me as well. So maybe my own confusion will trigger some brilliant ideas. My setup: 5DII, Nikon manual lenses (50mm f1.4, 105mm 2.5) with adapters. We shot some footage for a feature, hand held on the subway. Got home, looked at the footage and they were quite "jittery"...not just that shaky hand-held look (which is appropriate at times) but disturbingly jittery, almost unusable footage. I did a test at home using the same nikon lenses and a canon lens (IS USM) with the image stabilizer turned on. The difference is staggering. I've been hearing that you have to turn the IS off when shooting on sticks. I'll have to remember that next time I shoot that way. For handheld, I won't shoot without the IS turned on.

thanks Ofer. I've tried different shutter speeds, from 30 to 1000 - seems not to make any difference when panning.

Insung - from my experience, anything handheld other than extremely wide angle, needs to to have IS turned ON. The jumpiness you get from a non-IS lens is different to the problems I encounter when moving the camera on a tripod.
cheers

Sounds to me like this is just the way the camera is, it's got issues with movement because it's not a video camera. I assume it uses some sort of rolling shutter like other CMOS cameras such as EX1 which can have similar issues, and again not being primarily designed for video will have a less good one than the EX and therefore more issues. Most showpiece footage I've seen from the 5D has been static stuff - nice, painterly, super sharp, but static or very slow tracking shots.
I think right from the start people have been expecting too much from these video DSLRs.
Just my thoughts, I admit I've never seen a 5D or any footage from it except on the web.

This would be a show-stopper for me if normal panning and tilting is not possible. Can this be the case? many samples posted are fairly static shots.

I personally think is less about the rolling shutter and more about the codec encoding, but I'm, no techy.

It is possible to do fast pans without skips. I've done many.

thanks Al - good to hear that at least someone has had some success :)

can you post a short sample somewhere?
cheers
