i don’t know how to add images

put your images on a image hosting site… then type what is inside the speech marks without any spaces replacing URL within brackets with your copied URL for the image “! [ ] (URL)”

If you can post the same frame or very nearly the same frame… I did not want to have to rip another source just to demonstrate this technique so I screen grabbed from a DVD I think I might have been a frame out…Or my line up was a bit out. The Line up is the hardest part especially when the framing is so, so different.

There was a good reason to use that still from revisited because it proves that the Middle and top are unaffected more or less by the Luma key. And the added asteroids are still present although they are dimmed because there was nothing there in the other source.

After playing with the Luma Key some more I found edge softness 33.79& and very little tolerance around 96% yield better results. But this is the first time I have tried this so it’s all a bit of learn as you go. The line up really is the hardest part as I said before. I unsharpened the other source also as it was far too sharp. So please post what ever you want to for further tests.

What I am discovering though the software I am using is not precise enough in incremental scale to match geometry of the 2 shots as I only am able to scale in hole set increments and not percentages so I will never be able to match the size and scale with the software I have on this still image But with that said the 2 shots were very different in terms of the scale and positioning which is not entirely normal to have such different framing. basically my x scale needs to be in between 96 and 97 I think, and this is something impossible using the software I have. Or something has been done to extend the Star Destroyer at the far left because the lights don’t match so it’s either my software of the super stardestroyer has been digitally extended or elongated?

What is also interesting is if you keep the extra bit on the left from the Special edition / blu ray and the extra bit on the right from the theatrical it is quite nice too. And it might bee the correct aspect then but there is something at play here… Not sure what.

One more example and I think this proves that it will or does work in undoing black crush. Although I do think I have a slightly difficult task with the software I am using as I can only position with the mouse and I can’t nudge the image in any sort of direction without having to wobble it about left clicking. So yeah my software is not precision enough. But this is not the purpose of thread because It’s more about the technique of doing but the software I have it’s too difficult to position and scale effectively. But this process would work 100% providing you can scale and position much more precisely than my software can (Lightworks).
