OK,
I worked hard over the weekend, and here's what I came up with:
an additional plugin that does a "smart" Bob&Weave.
The algorithm is fairly simple:
Keep each dominant line the same (Top or bottom, depending on the
configuration)
For the other line, check each pixel:
if it is very different from the previous frame, interpolate from
the line above and below (bob)
if it's similar, keep it (weave)
The "similarity" calculation is a fudgy calculation based on the Pot
control on the configuration window
In summary, for the static parts of the image you get the full
resolution, and for the moving parts you get an interpolated, half
vertical resolution block.
It's pretty fast, not the best but really better than what's currently
in Cinelerra.
Also, the plugin interface was getting really crowded with all those
additions, so I reworked it completely.
I'd appreciate some feedback from whoever's interested (Andraz ? ;-) )
The patch to the current CVS is here:
http://jcornet.free.fr/linux/download/cinelerra/deinter.patch.gz
The full plugin code is there:

Let me know what you think,
Jerome
