Hi guys..

I've just finished a demo video for a client using digital image stabilization software in 3 different shots and situations.
I used 2 point tracking and some manual correction when the references were lost, anyways the software was fast and straightforward in doing it all alone.

Results were COOL!

Something to be taken in count.

Check the video....

It wasnt Dynapel. Dynapel systems I think they are real time hardware solutions for surveillance video, am I right?

What I've done is transferring the DV raw shots to the After Effects 6 and apply the 2 points stabilize filter. I have used this feature in many other video jobs for TV and video, but this is the 1rst time on heli shots. Seem promising if you have the chance and the time to post-produce after shooting.

Tell me more about the results and video quality of the Dynapel hardware you've been using..

You are in big trouble GauchoVolador... because now you have to tell us step by step how to do that!

Looks great!

Image stabilization

Being that we do a lot of this for feature films, I'll take a stab at it.

This is a standard feature in the better digital compositing packages. I'm glad to see it has come down to the After Effects level now, too.

Basically, 2D image stabilization involves choosing two points in your image for the software to track, and the software keeps those two points in the same place, moving each image around and rotating them to line the points up.

The downside is that the final image is physically smaller, simply due to the fact that you are shifting the images around and that you are pushing some of the image off the screen on one side and adding black (or in Gaucho's case, blue) on the other.

Trust me, this works better on high resolution feature film than video, especially when it is interlaced. But if the overall movement isn't very far off, you can get good results with it.

Now does anyone want to know how we do 3d spacial tracking from 2D film to add computer images to a moving shot?

Guys.
As gpyros well explained it involves the selection of two points in the image that you know for sure that subsecuentially will appear in the rest of the video clip.
These 2 references need to be two spots (in this case Ive chosen 2 point tracking option, you can track one, two or four points for perspective matching) that can be clearly recognized by the software, such as hi contrast elements like: the area where the cement pole changes the color from white to grey and the spot where the pole hits the ground. In the car example I selected the two wheels, and with the wind flag, the flag itself and the pole.

Im trying to post a screenshot of the software so you can easily see how it works...will try later, i doesnt work right now.

About how much it cost, the street price of this software is about U$S1000....really not cheap!!!!!! and it need good processing power and RAM.... but my full time work is TV and Video post-production so it is a tool that i use day after day. There are some artifacts related to how the soft deal with the corners of the picture, as gpyros explained... but I think that this tool is a real helper in some situations where you are allowed to chop out some areas of the image.

Will post the screenshot as soon as it works again...

Flyboy:

Thanks!

That's the plan - my blades are due in tomorrow (according to UPS tracking - finally!) so I hope to really start taking some serious pics soon!

Were you interested more in the Newport or the Balboa pier?

I'll take the second as a request for a shot of The Wedge with surfers thrashing around on the rocks by the jetty.

If the local police don't mind, I'll be all over the place. "But officer, it's only a quiet little electric helicopter, not one of those big, bad gas beasts..."

I'm going to put in a purchase order and get the Pro version. Is it stand alone or do you have to order adobe premier as well?

thanks,

Dynapel

Gaucho and guys,
Gaucho, your right , they do have hardware for surveillance,but guys look into dynapel first. I have the steadyhand software that works very easy and turns out GREAT also. I bought it a while ago, but was about $100 bucks.
www.dynapel.com click on products then video editing...
They have some demos on website( If i remember) and it does work!
Check it out, you may be surprized.......

Hey flyboy, hows it going? you still have my dream job!

You dont need to purchase Premiere along with After Effects. They sell AE as stand alone, but if you buy the combo you'll get an interesting discount for the two..it just depends on what you want.
Have in mind that AE is not only for image stabilization it is a compositing software...you can animate, color correct, short-form edit, format transcoding etc etc etc...it is a package for hundreds of uses...thats why it costs 1K....

AVSPHOTO
Never tried the stabilizing dynapel soft...you say it costs only $100...probably it is a better choice if you ONLY need image stabilization...AE is a complete video solution, you can do almost everithing you can imagine with a piece of video.

Here's the programs were using now;
Toaster 2.0 system with/
-Aura VT, Paint
-Lightwave 3D
-Modeler 3D
-Toaster CG

We just got it installed and are coming up to speed on it. If any of that has image stabilization I haven't found it yet.

The Dynapel looks neat but we do alot more than just Remote Heli video. We would need a truckload of Dynapels to cover everything. We post produce almost all our video anyway so the AF6 would be much more practical. However, with all the security work we do, the other Dynapel products would also be useful. But, one thing at a time.

The same could be said about your employment as well.

However it is nice being able to do what you enjoy and not be distracted with the buisness side of things.

I hope that you are well.

If you are ever out this dirrection, I would love to show you around.

Thanks for all of your help over the years.

Thanks to all of you above for taking the time to share and explain this fasinating technology.

Hell, yes !!!!! 3d is the easy bit (lightwave 7.5 ) realistic spacial tracking tips from the pros would help a lot.
so far Ive been just guestimating.

Is the tracker filter a plugin or is it built into AfterEffects? If it is not built-in and included, who makes it and where can you get it from?

thanks, awesome software!

It is built into AE,
Awesome program, but you do need to get into it to under stand its capabilities.
Does any one know of any good tutorials for After Effects, such as Image Stabilization?
Thanks,
