Interstella 5555 HQ 1080p (2x upscale)
Finally, I finished the 1080p version (2x upscale) of Interstella 5555. Get it from:
https://archive.org/details/interstella-5555-2003-1080p (download the 2.7GB MKV file & the SRT subtitles file)
or

You can get the 4K version here and the SD version here.
I processed the PAL DVD with Avisynth: deinterlaced with the best free deinterlacer QTGMC, removed duplicate frames and some ghosting with SRestore, slightly denoised with TTempSmooth, cropped the edges that had video artifacts, resized with nnedi3_rpow2 using Spline36Resize to fit into a 1080p frame (1440x1080).
I included 3 audio tracks: the normalized (higher volume) 2.0 audio saved as AAC, the original 2.0 & 5.1 audio tracks. Also I included the original chapters but I added the titles of each track. This video is H265/HEVC format saved with a CRF of 16 and preset medium.
Considering the issues of the source - some of them related to the DVD standard (interlacing - basically missing rows of pixels, blended frames embedded into video - that's the biggest mistake of whoever made the DVD, non square pixels, black bars and artifacts at the edges of the frames, noise and blocking artifacts, the audio volume too low) I think the result is excellent. If you're using a phone you can try VLC or MX Player to play this video.
Thanks for the positive reactions!
