>My analyzer says they have a video pixel size of 720x480 and display size of 636x480
DVD resolution in most cases is 720x480 (AR 1.5) which can either be scaled horizontally by applying the ratio of 8/9 (AR 1.33) or 32/27 (AR 1.78) depending on the aspect ratio flag settings.
>and all you have is a 480p video of post-effects work
The effects were mastered in interlaced, IIRC.
I'm not sure exactly which format DS9 was mastered on, that information is eluding me at the moment.
Betacam SP seems too restrictive on resolution, but it might have been used for the pilot and season 1. It may have been the format for TNG since their tape masters look comparably soft even compared to DS9.
Digital Betacam became available in 1993, probably after DS9 began production, but a clear upgrade for a production switch after pilot, mid-season or season 2. Digital Betacam (commonly referred to as DigiBeta, D-Beta, DBC or simply Digi) costs significantly less than the first 100% uncompressed D-1 format. See https://en.wikipedia.org/wiki/Betacam
D-1 or 4:2:2 Component Digital is a SMPTE digital recording video standard, introduced in 1986 through efforts by SMPTE engineering committees. It started as a Sony and Bosch - BTS product and was the first major professional digital video format. SMPTE standardized the format within ITU-R 601 (orig. CCIR-601), also known as Rec. 601, which was derived from SMPTE 125M and EBU 3246-E standards. See https://en.wikipedia.org/wiki/D-1_(Sony)
D-1 was notoriously expensive and the equipment required very large infrastructure changes in facilities which upgraded to this digital recording format, because the machines being uncompromising in quality reverted to component processing (where the luminance or black-and-white information of the picture) and its primary colors red, green and blue (RGB) were kept separate in a sampling algorithm known as 4:2:2, which is why many machines have a badge of "4:2:2" instead of "D-1."
D-1 resolution is 720 (horizontal) × 486 (vertical) for NTSC systems and 720 × 576 for PAL systems; these resolutions come from Rec. 601.
The Digital Betacam format records 2.34-to-1 DCT-compressed digital component video signal[3] at 10-bit YUV 4:2:2 sampling in NTSC (720×486) or PAL (720×576) resolutions at a bitrate of 90 Mbit/s plus four channels of uncompressed 48 kHz / 20 bit PCM-encoded digital audio.
Digital Betacam (DigiBeta) and D-1 offer similar capabilities which both exceed the quality of DVD. So while they are still standard definition masters, there is significantly higher bitrates on the tape masters than DVD or streaming offers, so upscaling to a HD format still presents some minimum picture enhancements, though still far inferior to a true HD restoration from film elements.
