There are no ongoing fixes with the capture method. The DdD board itself has been done and dusted for literally months at this point. Literally all of the remaining effort at this point is improving the software decoder, and making it fast.

Additionally, none of this process is specific to Domesday discs. The team is just using those discs as the go-to examples, because they are the Domesday86 project. It's simply a matter of course that the tech involved is directly applicable to capturing any laserdisc.

That single frame does a great job of shutting any "why not just use a capture card" arguments right up in terms of resolution, but to really put it into perspective how far the ld-decode project has come in the past year, here's a video of the Domesday National Disc intro decoded by ld-decode as of about a year ago: https://drive.google.com/file/d/1DQZ0bwqcRSaAQRfIuqhDg6xc7C1ttka_/view

Meanwhile, here's that same intro decoded with the latest WIP version of ld-decode off of Github: https://drive.google.com/open?id=1YAPvAjiguQ7zUZ2vQZL7Ix4HCLsmPBNE

Of immediate note are:
- Drop-out detection and correction is massively improved (or rather, it actually exists in the first place)
- Audio decoding is now implemented
- Color gamut is wildly improved
- Image stability is wildly improved

There are, nonetheless, still areas where it can be improved. Small dropouts of only a few pixels aren't yet detected, but there are some theories that it should be possible to detect them based on a rapid loss of frequency lock, rather than the current method which is to detect a sudden spike above or below the expected signal levels.

Anyway, suffice it to say that things are rolling right along. The main issue is going to be that the mainstay of the decoding process, ld-decode, is written in Python, and there's little interest on the Domesday86 team's part to port it to a compiled language. It's likely that someone will eventually have to port it between languages, and potentially make it GPU-accelerated, and that person is most likely going to have to be me.
