So, as I understand it, daphne plays the mpegs as-is, ie it does not speed up or slow down the actual source frame rate (say by telecining), but it converts it's internal frame calculations to compensate for frame rates different from the original.
you got it!

dvddaph 4.0 is coming?? That's great, can't wait. I did remember seeing some -blend posts, but I guess I didn't realize what it was; let's see...On-the-fly deinterlacing, using the "blend" method I presume? (as opposed to bob,weave,etc) - forgive how I sound, I'm just reading/googling this stuff as I write this. Great feature, I'll have to try this on some interlaced footage.
It's here. See the post in the video editing/capture forum.

I guess that means the ivtc scripts I'm working on are a waste of time. But on-the-fly "blend" isn't the same as a true inverse telecine, right? I think that makes me feel better (I'm just fixing some problems with the old avs scripts (dvd2daph3.0), which missed a lot of interlaced frames in the standard DL footage and did not work at all on the prototype footage; it's really only noticeable if you play it in slo-mo or frame-by-frame, but I'm a perfectionist.)
yes, ideally you would ivtl the streams for the best image quality. But, if you want the best image quality, you're better off learning the intricacies of capturing laserdiscs than playing with ivtl scripts. But, I'm sure there are people whowould appreciate your scripts once you're done with them.
dvd2daph used to ivtl and re-encode certain streams because it *had to* due to a bug with certain stream formats. But, that's now been fixed, so re-encoding isn't necessary. Thus, the ivtl scripts have been removed. The goal of dvd2daph is to give you the streams directly from the dvds with no visual changes, just that they've been converted to daphne format. Any sort of ivtl/re-encoding/changing of the video is a subjective art form and what is "best" is the opinion of the user. Therefore that part of the process is left up to the user. However, the files are perfectly fine as-is post-conversion for most users, especially since -blend was added. Hey, they were good enough for digital leisure to put on the dvds that way.
There's actually still one issue with dvd2daph 4.0 that we're trying to sort out. Seems like you know a lot about this stuff too. You're welcome in the chatroom, maybe you can help us.
