Thank you for the constructive criticism. You have inspired me to try out some things I've been kicking around. I have updated my script to 6.00. Turns out that I've nearly eliminated the problems you're showing with the Stormtroopers in smoke and the Rebel pic immediately following it, and it seems to have not hurt the stabilization too much! Please try it out and let me know what you think. (screen caps are nice BTW)

neebis, here's the contents of my HCenc .ini file that shows the custom matrix. Notice I also have the LUMGAIN set to 2.

Thanks very much for the updated script and your HCenc matrix. I'll start testing some clips for my next encode.

In the meantime, I already did a couple encodes, trying to get decent output out of HCenc as well as testing the audio, subtitles and chapters in a fill mux. I started out with Rejig, which crashed on me, then I tried Muxman which worked fine in terms of audio and video, but I think I have to do chapters manually (rather than importing the PGCDemux celltimes) as well as manually switch the subtitle colors. I might look around for other all-in-one muxing options. What do you use to mux?

After a couple tries, I ended up with a pretty good result from the HCenc FOX1 matrix with the following settings:

profile: best

dc prec: 10

avg bitrate: 8600

max bitrate: 9200

AQ: 2

VBR bias: 70

Lumagain: 3

mask: 60/60

I still haven't burned a disc, but after scanning through the HCenc output on my PC, I will change the adjustments I made to your script. HCenc seems to exaggerate the saturation, so I'll dial that back down from my previous setting. Also, the grain is obviously tough to compress and the final output was a bit noisier than I'd like, so I'll see if I can start with less grain, but slightly more sharpness, to see if I can squeeze a bit more detail out before re-encoding (maybe your new script is already moving in that direction).

Maybe it was already mentioned, but when comparing processed shots to the source, I have noticed a number of shots on the source with trails/ghosting in the original video, not to mention annyoing EE outlines or halos around sharp edges in a lot of shots. Of course, your script squeezes the best presentation out of this subpar source and makes it much more watchable than what George originally stuck us with.
