[resolved]Should I deinterlace these file before encoding them to a DVD?

[AviUser]

Hi,

I have a few different .vob files that I took off of different DVDs that I want to put onto one DVD. Basically, the DVD I want to make will have a different video for each of these .vob files.
I have and want to use Nero 6 because I can make menu's with it (if a free alternative that can make DVD menus and can use .avs exists, please tell me).

But some of these .vob files are interlaced.
Do I need to de-interlace them before putting them onto the DVD for higher quality?
Note: I will probably be using AviSynth for cropping/resizing/adding borders, so I don't know if Nero can detect if it's interlaced.

:thanks:

AVStoDVD? It makes menus, works with Avisynth, and is a pretty self-contained program. The author is a frequenter of this forum as well.

As to the interlacing issue, consider this - the native framerate for NTSC DVD video is 29.976 fps. This is usually achieved through 3:2 pulldown (read: 3 progressive frames to 2 interlaced frames). The proper way to do this is by using a technique called "soft-telecine". Essentially this sets some flags in the video stream saying "hey, for every 3 progressive frames, create 2 interlaced ones so that I am compatible".

The problem of mixing sources is that you get different mixes of interlaced and progressive content, as you have already discovered. My position is to return all of your content to a base framerate of 23.976 fps, through IVTC and/or deinterlacing, and then use a program such as DGPulldown to apply "soft-telecine".

If you were to use a program such as AVStoDVD, I would IVTC all of my content, feed it into AVStoDVD, and let it deal with the details of making it DVD compliant through "soft-telecine" and the like.

Hmm, thanks for the feedback. I will see AVStoDVD because Nero doesn't like taking .avs scripts...
About the interlacing, I'll look into that as well.

But, I won't respond until like Sunday at earliest.

If IVTC results play jerky don't denterlace as it will play very jerky on DVD players and look worse then keeping it interlaced.

It shouldn't matter if you mix interlaced stuff with progressive stuff. I'm sure the field order is stored in each GOP and should play correctly.Of course it must be set correctly.

Okay, I've installed AVS2DVD and... it doesn't take .avs files as input!?!?! But, the name of the program is AVS2DVD...

Or maybe I'm just making some dumb mistake :p
It does have a very nice menu editor, but so does Nero, so I don't see the benefit in using it if it can't take .avs scripts if you know what I mean.

About the interlacing issue, I think I'll just try to have them all deinterlaced before running them through the program so there are no complications due to avisynth not giving the right information to the encoder.

You are right it doesn't allow avs input, strange name indeed.

One benefit og AVStoDVD is it uses HCenc which is generally referred to as producing the highest quality for a free encoder and it's arguably second to only CCE. But your eyes may or may not notice a difference, would be best to compare if you plan on using one or the other regularly.

OK but it's going to be lower quality then if you kept it interlaced and it will play jerky on many players. If there were decent playback deinterlacers outside of ffdshow/avisynth it would be a complete non-issue to keep it interlaced. Maybe another thing you'll want to compare.

Yes, quite confusing... :cool:

BTW, AVStoDVD because it takes a video file, builds (for you) a AVS script and then converts to DVD.

Since you can edit the AVS script, you can load directly your video file and then add your script mods.

Umm, can you add the feature to load .avs scripts using AVS2DVD if possible?
It should be really easy if you just add a line of code that uses AviSource("script.avs") to open AviSynth scripts.

Thanks.

[MrC]

It is already in my ToDo list

Okay.

Thanks for making your program.

Import should be preferred to AviSource for opening an avs file.

I just downloaded your new version of AVS2DVD and it supports .avs scripts!

Thank you MrC!

I'm kind of confused. You want me to convert all my videos to non-interlaced 23.976 fps (using ConvertFPS for non-interlaced content and reverse telecining interlace content) and then feed them to AVStoDVD right?
:confused::confused:
:stupid:

[AviUser]

I don't know.
I am a confused person right now.
Please explain.
