Thought on de-SE'ing the DVD
Time
I admire your efforts. One fact just sticks out in my mind though: ANY laserdisc footage you splice in will be immediately recognizable as such. There is no way to reproduce the detail that the dvd's have, even after extensive, frame-by-frame filtering and color-correction. I still fail to see how anyone is going to be able to pull this off and make it look seamless.

Dark Empire Collection - OT LD to DVD set (* unfinished project *)
Time
This is what I do, and it works every time:

Capture from the LD source at full resolution without cropping. Make sure "top field first" is selected. You must have zero dropped frames.

In VDubMod: Video > Framerate > inverse telecine - Choose "reconstruct from fields - manual" and in the offset box put 3.

Start your video on the first progressive frame of the sequence (P P P I I).

Crop/Filter/Do whatever else.

Try this on a short clip first to make sure you have all the settings right. Not once have I found an extra interlaced frame in my video after this. The only thing I can't answer is whether any progressive frames are lost.

@ laserschwert - need you to explain something
Time
The code format there is just an alternate way of doing things that makes it easier to do complex filtering with avisynth. Basically each one of those vthings () is a variable being assigned whatever is on the other side of the equal sign. As you can see, each line has several commands that are put together with periods.

Looking at v1 and v2, you can see that each one is slightly different, as v2 adds a few additional filters. The important thing to note is that both v1 and v2 are separate video feeds at this point. v3 takes these two video feeds and combines them. This same method of combining two videos is done once again with v4a, v4b, and v5. In the end, the script returns the finished video, v6.

To use this in your own script, all you need to do is copy and paste, and of course change the plugin and avisource locations. If you already have an IVTC method in your script, then just replace the "SeparateFields.SelectEvery(10,0,1,2,3,4,5,6,9).Weave.AssumeFPS(23.976)" portion of both v1 and v2 with your own method, using the same syntax.

I hope that makes sense to you. If not, maybe laserschwert can explain a little better.

Sound question
Time
-31dbf is what you want. So setting it to -9 in Soft Encode sounds right. The reason it sounds so quiet is also explained in that thread (if you're referring to the one I think you are). Basically when the audio is transferred from the theater to the home theater, the wide range of sound can only be reproduced accurately if the whole level is brought down. You have to turn up your amp, and the result is that big explosions and such sound good while faint sound effects are still audible.

Wow, I actually figured this out.

Long story short, the code in that thread creates a mini program that allows you to input values for the capture card's advanced settings. The only thing is, the values have to be entered in hexidecimal format. Took me a while to figure that out, but I've got it tweaked so that I'm not clipping off the sides anymore. (yay me)

Thanks for the reply skeg. I saw that thread earlier today while I was doing a little research on my Cenexant chip. It's true that the CX2388x cards only capture 688 horizontal pixels. However, this is due to clipping on the sides as I found out using a program called Dscaler. With Dscaler, there are a ton of advanced settings you can tweak for your captue card, and among them is the clipping setting. When I uncheck this, the whole 720 pixel resolution can be seen. The major drawback to this is that you can't capture (stabily) with this program.

Another thread I found over at doom9 has a hack that will allow access to those advanced settings and still let me capture with VirtualVCR. Some if what they're talking about is way over my head, but I think I understand how to do it. And as soon as I finish, um, acquiring a visual basic compiler, I should be able to give it a try. I'm excited to see what other things I'll be able to tweak with this.

I think things are a little different with those older bt based cards. The newer conexant ones seem to be a little more compatible with different software. I've had success using a number of different capture programs, including virtualdubmod and virtualvcr. But this issue of the missing video on the sides is a little different it seems.

One con about this MSI card is that the included PVR software doesn't seem to work with Windows XP. I've tried a number of other programs like SageTV and ChrisTV, but to no avail. I don't really care about the TV aspect of the card that much though, and Media Player Classic (believe it or not) actually works well as a video player, so I can still watch TV through my cable box.

So I guess I'm not going to worry too much about my TV software not functioning if I change the capture card drivers.

Zion, another question or two about your sound approach. I am always intrigued when someone says they are going to capture using one set of discs and use the sound from another because the spectre of sound sync rears its head.

I was lucky in that my capture didn't have an issue. I captured sound and video at the same time and it was always synced up correctly. On the other hand if you start capturing from different source material I can never see how the person can figure it out enough to make it sync beyond looking and listening at it.

In your case, are you going to sync up your base wavs first? then create the different sound streams based on this one copy of sound, or do it by some other means?


What I'll probably end up doing is using the audio from the same source LD's (faces set) since it seems like the sound quality on the '85 mix LD's isn't as good as the THX versions. I probably won't be capturing the audio and video at the same time though, unless I determine that I can't sync them up properly. I'm going to create a master .wav file and make sure that it syncs up correctly to the video before I create the different dvd audio tracks from it.
