Well it looks like Gigapixel (GP) has finally released a video version of their program which sort of negates the weeks and weeks I spent scaling individual images into useful video. Initially, I wasn't impressed with Gigapixel until I learned how to deal with its quirks, settings and ignore the preview screen (that is not indicative of the final results). Also having AVIsynth do everything initially except the upscaling helped produce better outcome(s) for GP. Doing a lot of post-processing helps also.
So in keeping with this thread proposal of upscaling unique DVDs lost to time, I decided to upscale the Terminator 2 4:3 DVD. For those that don't know the 4:3 DVD of T2 was a semi-open matte version of T2 prepared under the auspices of James Cameron. The original frame was reformatted to best fit with the CRT screens at the time. It loses some picture but gain more in other dimensions. Overall it presents a version of T2 that is lost to time. One that Cameron really was a big proponent of at the time (read: his infamous Abyss LD letter)..
I've wanted to do a T2 project for a long time but haven't been very successful. I was never happy with my first project and the second which was to be graded to the Japanese Squeeze LD got lost in a HDD crash. So I figured I'd try this as a replacement for those.
So before GP's released of its video program, I upscaled large chunks of T2 and color-corrected it to the ~300 35mm frames I had. Processing runs about 7 frames a min on a good but not great CPU/GPU. That means I was getting 3 to 5 mins of footage done overnight. Not great but almost workable.
So here is some of what I've done so far as now I need to decide to switch to the video app. The frame by frame will probably give better results but its speed makes its results almost unattainable. I'll compare some later but for now here are some test pics the frame by frame way
GP Upscale+ deblocking+dehaloing+anti-aliasing+tiny bit of re-graining and color correction to 35mm frames.
