Pretty good results DE.

Is that purely a result of your AviSynth filter, or is there some manual tweaking as well?

I can't remember exactly what or how many filters were in place when I made that clip. It was mostly global colour correction, along with a few selective filters to tone down R2's blue or the redness of the sand.

DE

Here's a demo of a filter I've just created to take some of the polish off R2's blue shine (image also includes colour and brightness correction):

DE

So did you decide if you were going to share this filter with us or no?

I know I would like to mess with it.

anhlib.dll

"Messing" is all this is good for. Use at your own risk. There's no documentation (except that below) and it is full of bugs, it is very particular about the format of video sent to it, and makes many unwarranted assumptions which may not hold for your video. It is highly likely to crash if used in an unexpected way. The dll contains a lot of filters, not all of which I'll go into. The useful ones are probably:

badblue - removes blue caste, such as Star Destroyer engine glow

cyanide - removes cyan caste, takes a single weight parameter, 0.0-1.0

generic(1) - unpolishes R2

levellevel - takes a single parameter (0-255), boosts only brighter parts of video (useful for boosting dark explosions - try levellevel(240) on the Tantive IV explosion)

selectivecolour - takes 19 parameters and mimics Photoshop's selective colour filter. First 18 parameters (-1.0 to 1.0) divide into groups of three, representing Cyan, Magenta, and Yellow boosting for each of reds, yellows, greens, blues, cyans and magentas. Final parameter (false/true) mimics Photoshop's "Relative/absolute" checkbox.

converttoyuv32 - brightens video and converts to a new format, allowing the use of, and only of (other filters will go crazy)...

yuv - takes 7 parameters - the first two multiply U and V channels (0.0-1.0), the second two shift U and V (-511 to 511, I think). If the first four are 0, the third three define an RGB colour to be made white.

convertbacktorgb32 - must be used after converttoyuv32 and yuv filters to return the video to a viewable format.

Hmm, the Brighter version seems to add a very retro feeling. Perhaps we are used to heavier contrasts.

In the canyon shot pan, it looks a bit faded.

maybe its me but vader has some red tint in the cape? im not sure.

Otherwise i like the retroize approach :)

Still cant wait to see the new mattes

I'm not sure what you mean about a retro feeling - bear in mind that the original DVD is far too dark, but does look reasonable on computer monitors.

The canyon shot is a bit faded, but then I think the original is oversaturated.

Vader's cape did have a red tint to it, but I've now rewritten the filter so it doesn't affect blacks so much.

Haven't done anything on the new mattes yet.

DE

Thanks a lot DE!

do you think you could post an example script of how it is used and what else needs to be loaded for it to work?

Thanks again for sharing

Which one?

In the meantime, what did GL have against this little green guy, huh?

DE

anything basic really,I just want to try it on my LD capture and see if I can do something with it(Hoth scenes to blue,whiter snow,etc.),just how to load,what needs to be loaded with it,and maybe a few sample commands just to get rolling.

Thanks again and also for the fast response

Try the following (with the DLL in the AviSynth plugins folder):

converttoyuv32
yuv(0.9,0.9,-100,100, 0,0,0) # 90% saturation and shifted UV channels
convertbacktorgb32

converttoyuv32
yuv(0,0,0,0, 255,240,200) # adjusts colours so that beige becomes white
convertbacktorgb32

Thanks a lot for the samples,the first one is to tan,and the second one is to blue,but now I can start messin with it.

1 thing though,why is there a green line on the left side? is there a way to get rid of it? if not this won't work for me.

Thanks again for sharing the filter and the helpful tips,hope you are open for more questions.

I forgot about that - the green line is to remind me that the clip I'm viewing has been filtered. For now, try:

addborders(64,0,0,0)
# ... filter as before ...
crop(64,0,0,0)

Beautiful work!

Anyone out there got ANH in 1080p? Preferably an original broadcast - need a couple of screenshots. Your name in the commentary text! ;)

DE

Thanks Ady.

I've been in two minds about uploading this clip - on the one hand I like to get feedback, but on the other I don't want to be showing off all my changes before release. With that mind, this is my compromise - the new clip, but in low quality:

PS This, like the vane matte, wasn't done with 3D modelling.

First class, adds life to the scene and very subtle.

Over to you BmB........

J

lol.

Incidentally I don't see anything particularly wrong with that shot that wasn't wrong with the original painting. If anything is wrong it won't show up on youtube.

Yum...! On a separate but note unrelated not could this technique be used in creating shifting Ben's ghost to his house in ROTJ?

If layered 2D sections of the interior set were fed in could the be made to match the camera movements of the live action in 2.5ishD?

Err... you mean on Dagobah after Yoda dies? I don't think there's enough of the interior in ANH to be of use. Oh, and, why?
