  • LaserDisc stores the video signal in an entirely analog format on the disc, similar to a vinyl record but using lasers. In theory, under good conditions, the input signal is almost entirely reproduceable on playback (minus some degradation in the form of noise and dropouts).

    The end viewing result should be something very close to the master tape that was used to make the LD discs, which in this case should be the same tapes used to broadcast the show on TV.

    DVD uses the same resolution and video format as LD but digitized, so it’s pretty evenly matched and DVD has better numbers on paper, but where it fails is its use of lossy compression (MPEG2) to fit all that data onto a disc which visibly degrades the image quality quite a bit. This issue is compounded because they chose to jam multiple episodes onto a single 4.7gb disc plus various extras and bullshit resulting in even lower video quality.

    If only Paramount would get off it’s ass and make a BluRay release…


  • It goes something like this, capture to disk -> decode rf file to video and audio streams with ld-decode -> deinterlace and remove noise with Hybrid/Vapoursynth -> load into Topaz to boost res to 1620x1080 with proteus AI -> final editing, tweaking, and repairs with Premiere -> final encode to HEVC with Hybrid.

    Note: For uploading to YT I doubled the resolution again to juice more bitrate out of their encoder. This doesn’t really improve the quality for normal files, so 1080p will probably be the max for regular files. If you try to go beyond that with topaz it starts ‘creating’ things to fill the pixels with and it looks artificial…
