<font size="2"><font face="trebuchet ms,sans-serif">there is 2 differents approach here : <br></font></font><div><font class="Apple-style-span" face="'trebuchet ms', sans-serif"><br></font></div><div><font class="Apple-style-span" face="'trebuchet ms', sans-serif">2D stabilization :</font></div>
<div><font class="Apple-style-span" face="'trebuchet ms', sans-serif">mostly the result i got in my tutorial. even simpler it's what you got on the "lock tracker" feature in MCE. except you might want to have rotation and scale as an option (not that sometimes you can want only one of the free to be solved. so this approach use at least 1 tracker up to 2 if you want to solve rotation and scale</font></div>
<div><font class="Apple-style-span" face="'trebuchet ms', sans-serif"><br></font></div><div><font class="Apple-style-span" face="'trebuchet ms', sans-serif">3D stabilisation </font></div><div><font class="Apple-style-span" face="'trebuchet ms', sans-serif">this is stabilizing the camera, the algorithm is a bit more complex and rely on a group of point rather then just one as in 2D. I can't remember any algo right now, but I can find out if you need to (I have been working with it in the past). </font></div>
<div><font class="Apple-style-span" face="'trebuchet ms', sans-serif">As an example you have the tutorial in syntheyes. </font></div><div><font class="Apple-style-span" face="'trebuchet ms', sans-serif"><br>
</font></div><div><font class="Apple-style-span" face="'trebuchet ms', sans-serif"><br></font></div><div><font class="Apple-style-span" face="'trebuchet ms', sans-serif">3D gets better results than 2D no doubt, but it needs a 3D solve (reconstruction) first. so having both is good.</font></div>
<div><font class="Apple-style-span" face="'trebuchet ms', sans-serif"><br></font></div><div><font class="Apple-style-span" face="'trebuchet ms', sans-serif">I know Flame has a 2.5D stab, but I'm not quite sure how it works</font></div>
<div><font class="Apple-style-span" face="'trebuchet ms', sans-serif"><br></font></div><div><font class="Apple-style-span" face="'trebuchet ms', sans-serif">The main feature needed in both cases is the auto-scale. If you look at my tutorial, I added a factor to scale the footage at then end so you don't see the border anymore. Auto-scale should know what is the best scale for the entire footage, basically look for the frame which as the biggest stab value, scale it until you don't see any borders, and apply it on the rest of the footage</font></div>

<font size="-1"><font face="Tahoma">Hello everyone!<br>
<br>
We've got everything for video stablization now (in fact we've
got this for long time already). But i need your help again.<br>
<br>
Due to i haven't worked with tracking before this project, i'm
not sure how artists expects this thing to work.<br>
<br>
The simpliest way i think would be to define one marker as
"stable point". Like "Lock to Selection" works in Clip Editor.
But it could be something else..<br>
<br>
One more thing. Where it should happen:<br>
- Clip editor.<br>
- Compositor.<br>
<br>
Due to we can't really change video, it'll defenetly node needed
in Compositor. To make final shot "stable". But nodes can't be
used in Clip Editor so probably stabilization should be done
here too. But is it necessery?<br>
<br>
One more idea (probably which is directed to developers) maybe
it could be useful (and possible) to add some kind of "Movie
Clip Nodes" so pre-processed video sequence would be allowed for
clip editing and movie clip node?<br>
