Never mind - I found the plugin doc and created an XML file for KDEnLive
(attached). With that it works great :).
Now testing, but looks good so far.
A few ideas from first impression:
A channel chooser (choose the source channel for NIR and VIS from R, G
or B) would be useful (as written before) for people who use
non-infrablue filters.
I don't know how easy that would be to implement, but a legend/colorbar
on the side which shows the actual used palette and the mapped NDVI
values would probably also be useful.
>From the feedback on my first blog post on DIYD, it seems that there is
an alternative formula used sometimes with footage from drones, which
would simply be NIR-VIS. Integration of this formula and a selector to
choose would probably be useful as well :).
