Which field order should I specify for reinterlacing?

[brassplyer]

I don't have an app that will directly cut and save a sample from the .vob file that DVD Architect Studio rendered.

The free DGindex utility in DGMPGDec can edit samples directly from VOB or MPG. The reslting video cut will be an .m2v video file.

The linked videos are flv files.

You can download the files that I uploaded from the page the link takes you to. Look for the down arrow in the upper left corner or click on "file"

Yes, after selecting File -> Download I get a new page that indicates the file wasn't virus scanned and a button that says Download Anyway. The MPG file downloaded fine by pressing the button, but nothing happens after pressing the button with the AVI files.

What browser are you using? I'm using Firefox, download works fine for me. Are you pressing the button that says "Download anyway"?

I clicked "download anyway" in Firefox, then got the usual "play in..." or "save". I hit save and saved the videos. I didn't try it in IE (I hate IE).

First thing I noticed is the soft image and overall fuzz from VHS noise that shows up as grunge in dark areas (lower right of videos). The low bitrate didn't help.

Well, no the first thing I noticed oter than softn image was the poor color balance and flat-looking image. You can work that as you please. But if I were going to show off work on the 'net I'd at least try to make it look as if you made an effort.


The bitrate in the encoded samples is too low to do any work with. Better to try working with the original DV-AVI.

What I care about at this point is getting to the bottom of the interlace issue.

Btw, you're doing the same thing someone else did in a previous thread where I was using this file. The purple tint is supposed to be there. It's from the stage lights.

Likely jagabo can examine your Vegas output and come up with an answer. He's more of an expert at how encoding can go amiss. Otherwise we know nothing about the original or exactly how it was set up in Avisynth or Vegas.

Which prompts me to ask. Because this vid is for web or PC display, why are you sizing up to 16x9? The image is still displayed as a 4:3 picture.

[sanlyn]

My encoders didn't seem to have a problem with interlaced.
mpg = TMPGEnc Plus 2.5 (TFF, MPEG2)
mkv=TMPGenc Mastering Works 5 (TFF, x264)
I used BFF and got the same results.

AviSource(E:\forum\brassplayer3\A\59.97_prog.avi")
SPline64Resize(720,480)
AssumeTFF().Separatefields().SelectEvery(4,0,3).Weave()

I tried both IE and Firefox but both are pretty heavily protected on my computers. I was able to download your interlaced AVI file by using a VM and running a completely unprotected IE.

You interlaced the video at 960x540 the resized to 720x480 in Vegas. Vegas resized the video as if it was not interlaced. What you should have done is resized the original to 720x480, interlaced it, then imported into Vegas telling it the source was 16:9 DAR and interlaced. Or if you wanted 4:3 DAR, cropped the original to 4:3, resized to 720x480, interlaced it, then fed that to Vegas telling it the video was already 4:3 DAR and interlaced.

Makes sense to me. I'd start with the original capture and go into whatever direction the O.P. wants from there. Get one version, then go back to the original capture for another version. Resizing, then resizing again from the first resize, etc., etc.....VHS source can take only so much of that. And resizing interlaced video, well....I thought the O.P. should know better by now. I started to guess that's what the "bad" interlace looked like, but I wasn't sure.

For 16:9 DVD:

AviSource("59.97_prog.avi") 
AssumeTFF()
LanczosResize(720,480)
SeparateFields()
SelectEvery(4,0,3)
Weave()
ConvertToYV12(interlaced=true) # assuming rec.601.  otherwise, specify the appropriate matrix

Encoded with HcGUI:

For 16:9 DVD:

AviSource("59.97_prog.avi") 
. . . . .
ConvertToYV12(interlaced=true) # assuming rec.601.  otherwise, specify the appropriate matrix

...oops. Forgot to put the YV12 line in my script above, post #37. Thanks for reminding me.

I don't have the original capture, wanted to see what could be done with what I have.

Hm. Then your 960x540 59.97 is all that remains ? If so, that version represents the best you'll be able to achieve. You'll have to go through another resize to get to standard BluyRay 1280x720, and another resize and re-interlace or field-discard to get to DVD. Considering that you lost some chroma and some definition by capturing VHS to lossy DV-AVI, thereby imbedding tape noise and whatnot in your original capture so that any sharpening or other heavy-duty work for large screen or HD display is going to require some careful work. The limitations get more confining no matter which way you go. You can always burn the 960x540p as mkv to a data disc or hard drive -- I don't know what a standard player would do with that format, I never tried it. Anyway, it'll probably work out. As long as your satisfied....

Going to 720 x 480 for DVD.
