I updated the OP to reflect that we don't use torrents anymore, so you don't have to create them. We also don't use primary downloadable anymore (10-bit 4:4:4 MKV), so you don't need to create it.
Our primary encode is now 480p MP4.
- Don't append 512kb to filename.
- Don't remove duplicate frames, it has to have constant framerate.
- Don't do soft aspect ratio correction using codec or container, resize directly to 4:3 DAR before encoding. For games meant for vertical CRT screen, use 3:4.
- Use 8-bit 4:2:0 colorspace.
- If you're encoding 240p footage (earlier generations of TV consoles and Arcades), upscale by the factor of 2 before aspect correction. 480p and 480i don't need to be upscaled. For handhelds with small screen you can use bigger scale factor to get the result closer to 480p.
It's meant to be viewable in good quality on Archive.org, but we're still figuring out the best way to watch it live without downloading. Some browsers allow watching MP4s directly by opening the file link.
Latest Encoding Package
has all of the above, but you may need to tweak it to match your personal needs.
