This project started during the first Covid-related lockdown back in March 2020 and has been continuing ever since.
The “Enhanced Edition” features a combination of the 16:9 aspect ratio PAL-DVDs (for all live action scenes) and the 4:3 aspect ratio HD remastered versions (for all CGI/VFX effect shots), which were stretched to 16:9 to conform to the live action segments.
Basically, this is a higher quality version that focuses mainly on the “clean-up” of visual aspects of the show, like: Reduced motion stuttering (stable 23,976 FPS), deinterlacing, cross color reduction, noise removal, deblocking, dehaloing, deringing, anti aliasing, reduction of color banding, sharpening.
All borders have been slightly cropped to eliminate the “VHS-tape look”.
Slight color grading has been added to enhance the color representation.
Furthermore, the audio tracks have been slowed down to correct for the PAL-shift.
The releases (4K) are encoded as follows: H265 (mkv) at 20 Mbps with Main 10 @ L5 @ Main, BT.709 @ 10 bit, resolution at 3840x2160p (16:9 aspect ratio) with English and German AC3 5.1 audio tracks at 640 Kbps.
45-minute-episodes take up between 6,5-7,5 GB of space per episode.
The releases (1080p) are encoded as follows: H265 (mkv) at 2,5 Mbps with Main 10 @ L5.1 @ Main, BT.709 @ 10 bit, resolution at 1920x1080p (16:9 aspect ratio) with English and German AC3 5.1 audio tracks at 256 Kbps.
45-minute-episodes take up between 1,2-1,4 GB of space per episode.
The realisation of this project is a very complicated multi-step approach (f.e. using several instances of AI-upscaling software), so it may take a while, but it continues to go on.
