09-21-1991 – Complete Show

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 entire month of September.

Video input: 480i
Remastered Video output: 1080p60 (1440×1080 @ 60 Frames Per Second)

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 progessive 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 frame is ran through numerous neural networks which augment each image using large datasets to “fill in missing 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. This process takes up multiple terabytes per show in storage and requires a lot of heavy duty computational power.

Each sequence of images requires a “best guess” of which dataset will do the best augmentation 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 flickering. Images are re-assembled to create a buttery smooth video. ????
With this video, I converted all DVD files to MKV and merged them to create one continuous show, remixed with ultramatrix FLAC24 track from Charlie Miller (all songs flattened out into one long track to sync with the video, also had to extract the flac from original file and convert to PCM in order to merge the MKV files, as MKV with FLAC does not merge properly)

The resulting video is “remixed” with the original source audio and usually augmented further with multiple audio sources. I upload my “personal favorite source” in the youtube upload.

Unless the audio attached to the source video is already my semi-objective “best available recording, I patch the sound as well. I will usually use a SBD or “Ultramatrix” from charlie miller, though there are occasions I prefer a FOB or a normal matrix. (or a sbd mastered by someone else)
