Röyksopp - Remind Me - 4K Restoration

This restoration presented some unique and interesting challenges. Firstly, the known surviving archive master by Studio H5 is a mixture of both interlaced and progressive scan clips that have been rendered as a single progressive scan source in PAL format. Interlaced video that has been re-encoded as progressive frames in this case wreaks havoc on the AI upscaling algorithm. The surviving master also has a low bitrate audio track of only 136kbps. However, there are multiple releases of this music video. It was included on a promotional DVD that had the audio track encoded at a much more desirable 384kbps. That DVD is in a completely interlaced format that could be interpolated up to 50fps with good quality retention, but its render quality is sub that of the known master, the DVD could even have been a VHS source copy by the looks of it. Furthermore, the DVD contains many different scenes entirely. For example girl trades stocks in an entirely rendered stock exchange vs works in the IT department in the DVD version. Regarding the audio track on that DVD, it unfortunately presents further problems as the promotional release is an entirely different composition that lacks the "remind me" lyrics present during the initial interlude (which I personally prefer how it sounds as well). More problems arise as the song on the music video has its tempo modified from the CD release version of "Remind Me" (Someone Else's Radio Remix) as well as a different tempo than the archive master. I measured the music video release is roughly 0.35% slower tempo than the CD release. So simply audio matching this video with the CD's music is not possible. For this restoration I conceded and combined the first 20 seconds of the master with the remainder being from the promotional release track as the audio track. I would need the original studio audio recordings to properly recreate the initial interlude.
It should also be noted that the original master shows brief nudity during the dressing scene. This has been edited out to comply with YouTube policy.
