I have played a little with 3Denlive, and followed the discussion on the 3D Spider-Man.Exactly !
As shown in this tutorial about how to use keyframes, you can control all alignment and placement/zoom parameters to make them adapted at each time position of the video.
You are speaking about horizontal disparity. But, on some stereos, you may have a well-aligned whole image having some local deformations. When zooming on these details, you may need to completely re-align the zoomed sub-part. This is here where the "Automatic alignment" button takes a great part of its interest!
For example, in the Spider-Man case, you may have a well-align whole video, but it's very hard to get it properly with a well-aligned Spider-Man (in fact, the background seems to be a simple flat wall-paper!). You would certainly like to have a better alignment on it when zooming.
In the tutorial, see the first screen copy point 7, and third screen copy point 3 and 4.
Your explanations may be a bit confusing because there are two X tuning:
- the horizontal stereo shift in the Alignment configuration
- the horizontal position in the Placement configuration
In the same idea, there are two parameters that may change the size aspect:
- the horizontal and vertical adaptation in the Alignment configuration
- the zoom factor in the Placement configuration
