This started as a series of tests I was doing with ffmpeg, AV1 encoders and Topaz Video Enhance AI, but as I was putting more work into it and liking the results, I decided to do the whole series. Here's a brief breakdown of the process:
1. Mounted the ISO with Windows Explorer
2. Remuxed the audio and video to a .mpeg file with ffmpeg (-c:a and -c:v copy) (the files had roughly 50 minutes long, containing 2 episodes and the ending bonus)
3. Splitted the episodes and the ending bit using MPV to find the timings and ffmpeg to do the splitting (-c:a and -c:v copy, using -ss and -to)
4. Loaded the files into Topaz Video Enhance AI v1.9.0 to de-interlace with these settings: Engine: Dione TV v1 | Scale: 100% (no scale, deblur, deblock) | Add Grain: 0% | Out: MP4 CRF20 | Keep Audio: No (this process took about 19 hours)
5. Muxed the original AC3 audio and the de-interlaced H264 video into a .mp4 file using ffmpeg (-c:a and -c:v copy, using -map)
6. Encoded to AV1 using NotEnoughAV1Encodes v1.7, ffmpeg 2021.02.27, aomenc 2021.02.26 with these settings: Splitting: ffmpeg scene detect, threshold: 0.3 | Workers: 6 | Filters: all off | Encoder: aomenc | bit-depth: 10 | Speed: 4 | CRF 33 | OPUS 128kbps 2.0 (this process took about 13 hours)
7. Made the chapters by using the splitting times as reference and finding the exact timing with MPV OSD showing 00:00:00.000
8. Muxed in the subtitles (IDX+SUB) using MkvToolNix GUI v55.0.0, synced using the delay option and added the chapters
The menus were extracted using MPC-HC, by exporting the image on display to PNG. I tired to make the PNG images AVIF, but contrary to the video, the losses were kinda too much for me, so I left them as PNGs.
I know that might not be the most optimal workflow but again, it started as a series of tests so...
This was made using an AMD Ryzen 5 3600 (relevant to the AV1 encoding steps) and a GALAX RTX 2060 (relevant to Topaz Video Enhance AI)
Tested and working fine on: MPV 20210228 | MPC-HC x64 1.9.10.16 | VLC x64 3.0.12 | VLC for Android 2021-01-20 (running on a Snapdragon 845 and 4gb RAM)
