ML Upscaled/Enhanced 1080p60. Live audio comparison of STARTING LEGEND 1999 ～Face to Face ver.417～ Kaze ga Fuku oka + ROLLING STONE. This was the old (second) live band which emphasized keyboards. Comparison video of the same two songs from the encore concert in November 2001 with the new band and what was then, the new Yamaha PM1D digital audio mixing/sound system (with a vastly improved live sound, more guitars, and very clear separation of the bass and drums):

ML Upscaled/Enhanced 1080p60 (using this newer process). This concert (thankfully pro shot) was also live streamed (Real Media at a slide slow/low frame rate 160p resolution).
ML Upscaled/Enhanced 1080p60. This concert (thankfully pro shot) was also live streamed via Real Media at a slide slow/low frame rate 160p resolution (which made the 480p source look good). To get this upscaled, I used a different process (cutting out the ffmpeg step) by using Digiarty VideoProc Converter to transcode the MPEG-2TS source to 1080p since the output looked pretty good (the de-interlacer worked much better). I then ran that through Aiarty Video Enhancer AI to upscale/enhance that to 2160p60 (video detail plus frame rate increase) and then performed the final downscaling to 1080p60.
ML Upscaled/Enhanced to 720p from grainy 480p source (this was a more granular upscaling utilizing Topaz Video AI as the backend). The original broadcast (NHK POPJAM) was recorded using VHS tape (Panasonic VHS Hi-Fi). This is just the OA performance part (not the initial interview with Moriguchi Hiroko). The footage was originally digitized with an PowerMac 8500 (it had AV inputs making it easy to connect to a VCR). Video formats and compression technology (in terms of being cross platform compatible) was not great around this time. Since this was also on a Mac, the Quicktime MOV container format was used along with the Sorenson video codec (since it was included with QT3 and looked the best). A few years later, I re-digitized it (better tech) and used MPEG-4 (various permutations were created since then by others).
Trivia: these on-air performances with bands for music shows are normally backing tracks. Longer songs are also usually shortened (entire section and/or solo removed). Some performers would also lip sync (Hekiru's vocals for this were live).
