All Thief 2 cutscenes were processed through multiple ESRGAN models followed by some manual editing. Then, the FPS was improved from 15 to 30, then 30 to 60.

Backup original video files.
Copy and paste into MOVIES folder.
There is a CREDITS V2 video. This has a different, royalty-free song that I felt fit better. If you want to use it, delete the V2 from the name and replace the original.

Make sure to watch all videos in at least 720p, otherwise you won't see a significant difference.
The best results are seen in the B16, CS05, CS10, CS16 and INTRO videos.
YouTube videos were formatted to fit the 16:9 resolution, but the videos to download are in their standard 4:3 AVI format. I have personally tested all of them and verified they work in game without issue.

Akven for getting me started with ESRGAN.
Child of Karras and musictaffer for improving the audio.
