Thanks for the advice. I have also noticed the upscaler still not being “consistent enough” - it can’t hold on to fine details, sometimes even in the close-ups. Still the best I could come up with so far.
I’ve not watched it yet but I have a feeling that seasons 1-3 are going to be harder to upscale than 4-7 because the source videos are lower quality on the 1-3 DVDs. I think they used higher quality tape to edit from season 4 on as there is a noticeable increase of quality from season 4 onwards.
Unfortunately that’s true. Watching the DVDs, you can see noticeable quality differences as follows: Seasons 1 & 2 are visually just bad (some more than others), season 3 is better, but still not good, a markable improvement is season 4 (image is sharper, more grain is present and details are clearer) and from season 5 onwoards it’s good DVD-quality.
I think the reason is that (if I remember correctly) they used tapes for seasons 1-2 and went digital around the time season 3 came along, switching over completely in season 4.
It’s similar with Voyager, the first digital models were used during season 3 (the first completely digitally rendered Voyager model was used in the episode “Unity” I believe).
