And ask away. I think a v3.0 is inevitable in time, although I'd probably be starting more or less from scratch.

Back in October I said I had a couple of suggestions for improvements if you ever did a v3.0. Here now are my belated thoughts - but I stress again that v2.5 is an incredible achievement and this should be taken as constructive criticism...

The first is a problem inherent to Lowry's cleanup of the films for the 2004 masters:

The red lights at the far end of the corridor have a piercing intensity that just looks photographically unnatural.

Here's the same frame from the GOUT DVD for comparison:

There are several examples of this, e.g. the red reflections off C3PO's body here:

And blue here:

GOUT frames for reference:

This has been discussed at length before, basically Lowry's algorithm seems to have taken any highlights with a bit of colour, decided that they are obscured by film dust/dirt and given them a huge unnatural boost. The same process was responsible for the magenta blaster flashes and Luke's green lightsabre.

I'm not sure if there's an easy fix to the damage inflicted by this shoddy cleanup.

The second issue though you probably can do something about - compression artefacts. I was surprised and a little disappointed that there was noticeable artefacting in a 11GB video encode. I go back to the death star control room (but there are a few other places where it is particularly noticeable), look at the macroblocking on the wall and hand, and the mosquito noise around the lights:

For comparison, here is a screenshot from a 1080p HDTV encode that is only 8GB:

Did you use x264 for the encoding, or some other encoder?
