Quote: Keep in mind using a cheap card or cheap equipment doesn't need to be part of the equation. It doesn't need to be a solution for the common man because there are so few laser disc games, even 1 person could realistically do them all himself.
Sorry, but i dont really understand what you mean by this.
I am fine, as long as we can hold a discussion like grown-ups. Of course even 1 person could capture all LD games, but he still would need at least two weeks, maybe more. He still would need to know, what he is doing to meet the requirements. I am not going through this hassle of work just for educational and development purposes and that those captures afterwards would not be considered a good dump and nobody (the public) will ever use it for gaming.
Yes its true, i have no clue about DAQs, Logic Analyzers and such, but to be honest for this purpose, i am maybe to dumb to see the relevance for such a setup. It doesnt make much sense at all for me, because the benefit is minimal to none. This is a conclusion which even Dave from the Firefox thread has come, a man that build a hardware emulation of a LDP. If the MAME devs think, all of this is needed, i sadly think that some of those games will be gone forever.
On the other hand, i have a clue, how to do a proper capturing from a composite output. I worked long enough in a tv station and in different post production houses, that i know how to do it. How to treat interlaced material and so on. I explained my concerns in the previous posts and why i think the approach in the past is not ideal. I am open and interested to hear from you, why i am maybe wrong with my conclusion.
Most of the source material (content/master) is so bad, that the wanted scientific setup will not make it better, rather and possibly more worse (why? it is explained in the firefox thread). The gain (if there is any) is not worth such a effort, it would also differ from LDP model to LDP model, there is no 100% accurate and there are possibly even things that you will need to sacrifice (like the interlaced content). So you need to ask yourself, what you want and what will you do afterwards. Its a dying medium and we can be happy if people have a working game. Dont get me wrong, i understand the preserving factor and i am interested in keeping it, as far and good as possible with my knowledge and equipment, what i would use for that task.

Again, i dont understand this as a whole. My capture would be a single stream, with clean VBI data. Reading Aarons articles, the VBI data of course, would be different for some games, just like it is on the original LD medium. Interpreting the differencies in VBI data, is the task of the emulation. It needs to work like the Dexter hardware, that needs to be set properly prior starting any LD game (i.e. choosing the right LDP model). But the 525 lines expecting approach is wrong, for the reasons i previously wrote. VBI data should not be treated (by the capture card) like picture content, like it was done and expected in the past.
If you are willing to discuss the topic, i am gladly in. If you think i am just typing here for fun and only a stupid troll, i at least would know its pointless for me to go further.
