Best way to convert interlaced video with dvd2svcd?

[KeepWalking]

I capture a interlaced VHS video to .avi whith huffuyv codec.

I need to convert that video to dvd, with dvd2svcd, but I'm lost. I don't know what the type of "Interlacing" option that I use, "keep interlaced", "No deinterlacing", or other?

I watch this movie only in TV.

What is the best way to convert it to dvd??? What the options I need atention when convert it??

Hi.

To deinterlace or not to deinterlace, that is the question.

There are a couple of factors you need to consider.

Firstly, will you need to resize vertically? ie what is the vertical resolution of the capture and is it one of the DVD-compliant resolutions (288 or preferably 576 for PAL or 240/480 for NTSC)

If you will need to vertically resize there is a strong argument for deinterlacing as deinterlaced footage is much easier to resize and is actually slightly more compressible.

However, as long as you are not trying to get more than a couple of hours' footage on a DVDR, keeping interlaced is likely to be the best option as long as no vertical resizing is necessary.

To do this, just select Keep Interlaced in the deinterlace dropdown box on the conversion tab. The rest of the settings will be updated as necessary.

Tks Nick for your reply.

I don't need to resize vertically. I capture to 640x480, my resize is only necessary in horizontally, to make it dvd compliant (704 x 480).

Then, i think that is not necessary to deinterlace, right?

One more question about the CCE templates that I look in the other posts (Progressive and Interlaced templates). Is necessary to select it in the Enconder Tab, CCE Paremeters, or DVD2SVCD (last version) do it automatic for me??

Honest answer, I just use CCE 2.5 with the "out of the box" settings and no custom templates. The quality is good enough for me so I never really experimented too much.

One little quirk with the last version - in the Aspect Ratio dropdown you will need to use "16:9 - Borders added, Encode as 4:3"

This sounds (and indeed is) somewhat illogical but just trust me on this one! Check out the preview pane to ensure you're getting full screen output before you start, but you should do.

The main reason I switched from CCE 2.5 to CCE 2.67 was that I thought there was an improvement in my interlaced encodes, whether it's the interlaced template or 2.67 itself, I don't know......

The SimpleResize dll has an "InterlacedResize" function that works pretty good (only in YUY2 though I think?) if you need to resize interlaced material.

Also make sure you know your .avi's fieldorder (top field first, or bottom field first) and set DVD2SVCD accordingly (encoder tab), or bad things can happen:)

One more question.

Is there a software to determine what the fieldorder of an .avi file?? How I can determine ???

Actualy I'm using VirtualVCR to capture my old VHS movies. It's work perfect, but when dvd2svcd will convert it, a audio problem was ocurred. The audio extraction no extract correctly, it do not extract entire audio, in certain part its cut the audio, and conversion with besweet cause some errors.

When I extract the audio with virtualdub, it extract correctly, but i need to do manualy.

Is it a bug in dvd2svcd?? any way to solve it??

For your audio problems, try checking internal extraction (I think that's how it's labeled, I'm working from memory here) under the Audio tab, that fixed similar problems I was having with DV-AVI's.

[ralphthedog]

The best way I've found to check field order is to write myself a little avisynth script (in Notepad)

AviSource("D:\dvd stuff\capture\vdub capture edited.avi")
AssumeTFF().SeparateFields()

Make sure you change the path to your .avi, save it with .avs (instead of .txt) on the end and play it in virtualdub.

If it plays nice and smooth, its top field first, if it's all jumpy, and has a one step back two steps forward thing going on......it's bottom field first (you can change AssumeTFF() to AssumeBFF() to double check).

I have had problems myself a couple of times with the audio extraction in DVD2SVCD. I just use virtualdub to save the .wav over the top of the extracted audio from DVD2SVCD and crash recover from audio conversion.
