This really is the way to go — it captures the signal directly from the disc, which is then processed using the open-source ld-decode software. This allows for some fairly advanced recovery, including dropout correction/repair. As the software is improved over time, the captured data can be reprocessed, resulting in improved conversions. One downside, though, is that each capture can take as much as 40-80GB per disc.

Unfortunately, setting up a capture environment is not the most straightforward —among other things, it is necessary to calibrate the LD player using a GGV1069 calibration disc. I'm not sure these are still available, but as of 6 months ago or so they were from Donberg Electronics and PacParts.

More detailed information on this process can be found at https://www.domesday86.com/?page_id=978 <https://www.domesday86.com/?page_id=978> and  assistance can be obtained at the project Discord which is linked from https://www.domesday86.com/?page_id=416 <https://www.domesday86.com/?page_id=416>. If the quantity of discs does not justify setting up a capture environment and VCF is willing to mail the discs to a project member for capture, it might be possible to arrange for this as well — they are very much interested in getting non-movie LaserDisc titles captured.
