T2i Fixing jello?

I shot some fun footage and some of it has jello. (there is a video I posted in the HDSLR screening room, the one about taking her cloths off)

It was not really planned, just shoot and see how it goes. Well some of it didn't go good and there is jello. Can you correct it by keyframing a cornerpin or is there any free software that can do it? (or any software for that matter)
 
This is why they make stabilizers...your best bet is to plan ahead and avoid censor wobble by keeping the camera steady, can't answer your question about software correction, but I can't imagine it working well if it even is possible

after effects will stabilze your footage! You'll lose some of your outside frame though so you have to crop the final after effects output to get rid of the moving black border!

Using the basic stabilizer doesn't really work with jello'd footage. That's due to the rolling shutter and there is skew present in the image. So technically one section of your image can be just a hair off, but another section could be off far more.

There are some software plugins that will fix your footage, but it really depends on how bad the footage is. Here is one:

I know there are others out there, but this is the one that came to my mind first.
 
Coremelt is for Mac only (I'm a pc guy)
I did download the foundry rolling shutter and will test it out today.
Free ver works for 15 days.......
 
Does anyone have any examples to show of Core Melt? The demo stuff on the website looks decent, just wanted to see some production examples before I plunk down some money.
 
I think you will find that none of the solutions mentioned work very well for CMOS jello issues due to vibration . Only linear skews in 1 direction are usually corrected satisfactorily . Vibrations affect the sensor with different motion vectors, so as the scan is progressing it can be picking up different parts the image moving in different directions. The OP's video has vibrational issues, and probably won't get get "fixed" very well .
 
It looks like the op removed the link to the footage in question, but I can tell you Core Melt works really well. It even asks you what camera and settings were used to get the math right. Of course the best option is to shoot it right, second best with CMOS is Core Melt Locked and Loaded. In my opinion.
 
I removed the video. I couldn't use coremelt (pc guy) but the foundry software didn't work well in this case either. As PDR said, it's mostly vibrational problems, not your typical panning too fast type skew. (which the foundry stuff may have worked on)
The shots that had the problems were handheld, lens wide open, windy and started raining so I didn't get a chance to reshoot the bad scenes.
It was just a fun video which will be reshot in it's entirety. (correctly) but at least now I know the limits of the camera. (and my abilities)
