Adobe CS5.5 ae resolves rolling shutter

I went to the launch of CS5.5 last week, they have some new goodies add not big fire works but in PPRO CS5.5 they have a new colour control app you just right click and launch the new app and you can then adjust ,this cators for the new nikon format and the big one is AE you are able to sort out the Rolling Shutter issues .

Underfornate Adobe did not spend much time on PPRO or AE , most of the time was able EPublishing products.
 
Rolling shutter corrections is something that ever modern NLE should offer. The corrections have been available for a long time in plugin form for various NLEs and compositing tools, such as The Foundry's excellent plugin, http://www.thefoundry.co.uk/products/rollingshutter/

I think NLEs should be judged not by what features they have, but what features they do not have that their competitors offer.
 
You failed to mention that the Rolling Shutter plug-in from The Foundry, for After Effects is 300 GBP. Depending on the exchange rate, that's $450-$550 USD for us devalued currency Americans. I think that the AE users are breathing a little easier now that CS5.5 comes with an internal plug-in that boasts similar capabilities. If the Adobe version is as good ... then I say ... "score!"
 
You should clarify about "rolling shutter issues" because rolling shutter causes flash banding and also skew. I would think this software attempts to cure flash banding. I would be surprised if it could fix skew.
 
I wouldn't -- because even iMovie '11 has skew correction! Believe it or not... it has a specific rolling shutter function for correcting out skew.

An automatic flash band fix would be nice.

I don't know of any software that attempts to correct for full-on "jello" or the scrolling waves from discontinuous light sources though.
 
Does it work? Seems like a lot of "stuff" to happen to correct leaning verticals and make up information that is not there.
 
I'm not an iMovie user, so I don't know how well it works; Philip Bloom was demonstrating it and he seemed pretty impressed that such a capability would be available in a program like iMovie.
 
These plugins cannot always provide a fix, they only fox for the effect of camera movement, not object movement - like a bus passing in front of frame. They also do not fix other problems like jello waving arms.

They are all the same problem, if it solves one it solves all of them.
 
Yes, the new Warp Stabilizer in After Effects has an option to correct jello ("skew"). I have no idea if anything addresses flash banding.

I have not yet tested the new AE 5.5, so I can't comment as to how well it works. According to Jason Levine's promo video -- it's magic. As we all know, "results may vary" from promo videos.
 
Vegas Pro 10 has had skew/jello correction (as well as stabilization) for a while now, via ProDad's technologies. It works reasonably well - depending on the extent of the issue.

there are plugins like the foundry's that apply local skew....for instance fix the train and not the pole....in theory

Hmmm... it should be fairly straightforward to DETECT fast moving objects vs. camera motion using standard motion flow algorithms... but the correction of moving objects, especially for partially occluded objects, might be tricky... though using multi-frame processing, I guess one could do a pretty decent job of it... I'm gonna hunt down some more examples!
 
No - it is not physically possible to solve object motion problems, as the "wrong" object in it's jello form is occluding background pixels that do not end up getting recorded- how do you restore those pixels?
 
It can be very difficult, because sometimes things are subjective. Was the branch of that tree through the windows of the car slanted or was that skew? Or, what if you are tracking a group of moving objects, and they are moving across the sensor at different speeds. Some stationary to the frame, others zooming by. Like Robert said, these can be difficult to fix. I've seen some tools that do try and help you guide the tool to fix these, but I've also seen the results and they are not the best either in many cases.

For just panning fixes where everything is stationary, you could fix this yourself NO problem in AE with automation.

Adobe's got their procedural generation stuff...I haven't tested to what extent the warp stabilizer works on rolling shutter, but it for sure can generate the edges of the frame so it doesn't need to digitally zoom in when it stabilizes the frame. I'm pretty sure it also corrects for parallax in its stabilization (although you have the option to only move the frame in case of artifacts).
 
Standard motion flow algorithms will track objects moving at different speeds; multiframe processing indeed can be used to fill in occluded pixels… just not sure the research has been applied fully to the NLE world yet…

It can but generated pixels often look unacceptably weird. Once in a while you get lucky, but better to just shoot with a better camera, or avoid troublesome motions.

Parallax correction cannot really work except maybe for very simple flat objects - and I doubt at all. At some point there are limits to artificial intelligence, and computers can only do so much without hours and hours of human guidance.

Well, you should take it up with Adobe. They call it Subspace Warp, and there's some technical info on it here:
