Is it possible to use another source to fill in for the missing frames? I know the purpose is to preserve the film, but there are missing frames, which is unfortunate. It seems to be just under 5 seconds missing…could (gasp) GOUT frames upscaled be used to fill in these gaps? Obviously not a great solution, but would it be better than black frames to get it GOUT synced?
On a side note, absolutely terrific work, -1! Much appreciated!
