Shaky clip

Hi there. I think this might be a good place to ask this question.

I have a shot in a short film where I used a dolly. It's a pretty important shot and unfortunately I used a pretty horrible tripod during the take and now I have quite a bit of bump in my footage. Is it at all possible that someone here can "fix" it? I'm willing to compensate what little money I have to get it fixed. I shot it using the Gh1 in 720p 60p. I'm wanting to slow down the footage to 40% as well. What do you say, any takers?

Of course name in credits is always a welcome.
 
I can give it a go if you want. My e-mail's in my profile, if you give me a way to get the footage I can take a look.
 
Converted the file, threw it into AE, but realized the DOF was going to give me trouble. I gave it a shot, but so far so bad.
 
The biggest problem IMO is the "bump" section and the fact that you shot with a CMOS camera. There is jello as parts of the frame have different velocity vectors - you won't be able to repair that - any stabilization attempts will look very unnatural over that section

The rest of the clip shouldn't be as much of a problem with a planar tracker (e.g. mocha, mokey). AE's internal tracker is a point tracker, and as mentioned above, there are not very many good stable points to track (because of the DoF, the points tend to "slip off")

There is a rolling shutter plugin from the Foundry, but it only works well on linear pans; the jello-bump-shake type errors are not handled very well by it because of the different velocity vectors

If this is important , I would reshoot it

reshoot was my first option, but the guy is SAG now and can't do anything on the project anymore. fusking sucks.
 
I was able to do a reasonable job, but it would indeed be better to reshoot this. I wouldn't use it unless I was forced to.
 
Is the bump section an important part to retain?

The planar trackers seem to work fine on the rest of the clip

I'm at home right now, but I have the rolling shutter plugin installed on a computer at the office, If I have time, I can have a go with it tomorrow and see if it makes a difference. Sometimes it does work ok on the jelly shakes... Are you on some kind of deadline ?
 
if i can keep the shot steady up to the point he pulls out the gun, perfect. if i can keep it steady up to the point where he gets off the bed and throws the card perfect. but really want to eliminate any and all the shake possible up to that point or further. and if i have no choice i'll just fade to black and then fade back when he's standing at the door.


no real deadline. this scene is edited but this one clip.
 
If you don't need it rock stable (i.e for compositing purposes), but just to elminate most shakes , deshaker in vdub will do a decent job. I did a quick test and it actually handles the bump section fairly well (it has partial rolling shutter compensation, and edge compensation modes). Best of all it's free
 
Was anyone willing to tackle this? I'm not opting out doing it myself, if it comes down to it, but really limited how much I can do by myself already. I'm editing and CCing and sound and ADR...etc... I just need an example what can be done and up to where it's not possible.
 
I have something, but it needs refining and I've not got a lot of time to really refine it.

The trick, I think, is to switch trackers a lot. So far I've been tracking 2 points using the standard AE tracker and correcting for rotation. But, the actor walks in front of them when he gets up - so I switch to another two temporarily until the first one is clear again - then switch back.

It's not ideal and makes for a pretty busy composition, but it's the only good way I can see.
