Extracting Digital Video from LaserDiscs?

americanatavist asks: "I was wondering how feasible it would be to digitally copy LaserDisc movies to DVD. Clearly this would require the standard suite of tools to make a DVD. What method would yield the maximum level of quality? Is it worth the effort to find a means of extracting the digital information using an LD-ROM drive, or would the S-video from a regular LD player suffice?"

method of digitizing a laser disk

[RogueScientist]

A laser disk has pits on the disk that vary in length and position in the sequence. So essentially you have a time and amplitude domain that generates a analog waveform. Why would it not be possible to construct a special apparatus that reads the length of the pits as accurately as possible and store that information in a data file with a 64 bit number for each pit with a time? Once you have this the data you have captured is digital and can use the necessary analysis to generate the image information from that data? It seems a lot better than dealing with disk players that are taking this information doing various filtering on the information and working with the generated analog frequency waveform.

Re:doing this with origional STAR WARS trilogy

Actually if you buy (or bought) the trilogy on tape, you can download and view those.
If anybody ever gives you any shit about it, tell 'em I said it was ok.
