DeHalo_alpha() actually lightens the source. It is Tweak() that pulls it back down again (“bright=-5”). Avisynth docs note that Tweak()'s variables are floating-point. One should be able to set “bright=-4.5” and get a compromise-image between the two previous test results.

Aside from non-pro LCD monitors’ “what you see isN’T what you get”, the sequence of processing in Avisynth may significantly affect the result. I didn’t realize all the extra processing DrDre was throwing at it outside of the super resolution program until I read his last version: Star Wars GOUT in HD using super resolution algorithm (page 50) - SRV15.

While I’m at it, here’s a warning about ConvertTo???() – to change the colorspace. It’s considered prudent to make minimum use of this function by grouping same-colorspace processing under a single ConvertTo, or by only using functions that operate under the same colorspace. Colorspace conversions have rounding errors, which compound in the destination. I counted one, two, three, four, … well, allot of ConverTo’s, and each use negatively impacts the final product’s integrity. That part of the script, at the very least, should be optimized.

Oh, yes, I used DrDre’s SRV15’s screenshot from the Star Wars SRV11-to-SRV15 comparison - frame 8228, also from page 50.

@ DrDre
BTW, AWESOME project!! Loved following it and your results!
(“THX 1138” laserdisc needs a similar treatment. Hmmm, but why does that ring a bell? Oh, yeah … another movie from that same Lucas guy!)
