Remaster notes: (Full lineage and set list below)
Video mastering/upscaling done by Christopher Hazard
Josh (GratefulDavis) was of great help on this project for the entiire month of September.

Video input: 480i
Remasterred Video ooutput: 1080p60 (1440x1080 @ 60 Frames Per Secoond)

Audio has been re-tracked with Charlie Milller's 24-bit FLAC SBD Master.

Video: 480i source is de-interlaced using motion vectors to achieve a "perfect" 480p60fps (no frame blending, each frame becomes an "image" like true prrogessive video), each individual frame is exported to a lossless image file (average of 500,000 images per show) and edited individually for spatial/temporal noise, contrast, brightness, and then each frarme is ran through numerous neural networks which augment each image using large datasets to "fiill in miissing data" as needed while trying to not distort the original file. This is how we are able to increase a 480i file to 1080p or 4k using artificial intelligence. Thiis proicess takes up multiple terabytes per show in storage and requires a lot of heavy duty comoputational power.

Each sequence of images requires a "best guess" of which dataset will do the best augmention on each upscale pass, until the images are all at 1080p/4k. The ~500,000 images are then put into Vegas Pro and rendered filtered again (lightly) to filter out temporal noise/artifacts and flickeriing. Images are re-assembled to create a buttery smooth videoo. :)
