Added you in steam.
For this type of cutting you'll need to do it by hand, because (if it's like in ff7) the animated layer ins't only the animation but also some pixel around so no way to automate it to my mind
 
Oh that really sucks but I guessed so. :(
How are you handling alpha layers as esrgan wipes them clean? :)
 
As said first i make full picture (with black backgroud)
At the same time i generate a 4x inverted layer for each file (with the use of color FF00FF almost not used in ff7).
Then upscale.
Then merge the final resized picture with the 4x inverted layer.
Then delete FF00FF to get back the alpha channel
All that batched with the use of imagemagik (and potrace for the vectorisation part)

exemple:
base resized picture :
base.jpg


inverted 4x vectorized layer (white part is alpha channel):
128.png


merged:
02.jpg


delete FF00FF:
03.png


The hard part is to do a correct vectorised layer to get a smooth 4x layer and avoid missing part of the vectorised picture (for that i merge a vectorized and a scaled version of the 4x layer and it's avoiding most of bugs)
 
After more tests, i'll use manga109 in some fields (i merge a manga109 upscale with some grain prefilter with a manga109 upscale without prefilter - 30%prefilter/70%standard).
If there's lots of rock or trees or vegetal forms le manga109 if better than my old method, but for any "human construction" my old method is better.
So let's gimp each picture to use both manga109 or my old method or a merge of both ^^

@Fraggoso :
Thanks for the manga109 model info, i haven't seen it before you tell me
 
Satsuki it's great to hear so much dedication.
Glad I could help you out a bit. :)
 
To use this resize tool, just follow the instructions here : https://github.com/xinntao/ESRGAN
By the way i'm making now a new full upscale pack (video, battle, fields) with a more complex method and some manual tweaks (release maybe in 2 or 3 month):

Well that page doesn't really explain anything I was just wondering where I can download this converter.
