Restoration tips: the Slice Technique™

1 Replies, 5056 Views


What’s about this so-called “Slice Technique™”?
In few words: achieve the widest (highest) image possible adding a “slice” of another video clip.

Be more specific…
Well, sometimes there are two editions of the same movie, where one has more image on one side, while less on the other side, and vice versa. So I thought to use the missing “slice” of one joined together with all the other, to obtain the widest image possible. Indeed, it could be only (e.g.) 3% wider than any each version, but I much prefer a 100% wide image Vs a “mere” 97%… (^^,)
Of course, it’s quite difficult – sometimes impossible – to use this technique with every movie, because what must be taken in account are the dimensions (eventual image rotation, width and heigth of sources and chosen slice, eventual resizing and cropping, exact point of matching), colors (both versions should have the same color grading, or one should color match the other), video quality (grain, resolution/definition, different compression used in the sources, frame whobbling in a version not present in the other – in particular at the beginning and ending of a shot), etc.
In these examples, I used a vertical slice and two sources, but it’s possible to use an horizontal slice, or even multiple slices from various sources – obviously, in this case, a good result will be astonishingly difficult…
Hint: best results are from two versions with same resolution – like 2 Blu-rays, 2 DVDs, 1 Blu-ray and 1 HDTV.

It looks like there’s more image at the bottom in some shots on the XXX Vs. YYY. It is possible to adjust that too?
It is not possible to use it, as the small “slice” on the bottom of the YYY is missing… like the following example:

see the missing piece at the bottom right? Unless there is some method to “invent” the missing piece using surrounding images… and I’m afraid, there is not (yet)! EDIT: if the corner is small enough, inpaint could be used; result may vary from quite noticeable to perfect, depending on source and size.

How about using XXX as the main source and just adjusting the colors, instead of using the YYY?
It depends… if XXX color matched with YYY as color reference is better, then use XXX; if not, then use YYY – I must add that sometimes the best solution is to use XXX for some scenes and YYY for others… your mileage can vary!
