Blues Clues DVD NTSC Interlaced

[nandi_nokuri]

Hi I am trying to make svcd out of this blues clues dvd. However when I played it in my dvd player it has huge comb lines in it and sometimes slows down then goes back into sync. I have an Apex 500w if that helps. I am wondering if this has to with the encode mode, can I select non-interlaced and then deinterlace ?

Nandi, you need to supply some basic information, such as how you got your source from DVD to SVCD. What programs did you use to rip? What type of source is your material (Interlaced, Telecined, etc).

Sorry. I ripped the dvd with dvd decryptor from dvd2avi it was ntsc interlaced 29..... I didn't itvc because From what I can tell its a pure interlaced source.

nandi,

Using DVD2AVI and Pressing F5 to view specis of DVD source:

When its:
---------
Video Type: FILM
Frame Type: Interlaced
* you can bet it's IVTC Interlace (every 4th and 5th frame is Interlaced)
--> OK to process w/ Forced Film on

When its:
---------
Video Type: FILM
Frame Type: Progressive
* you can bet it's PURE Progressive (every frame is progressive)
w/ FILM 23.976
--> OK to process w/ Forced Film on

When its:
---------
Video Type: NTSC/FILM and bounces back and forth w/ low %
Frame Type: Interlaced
* you can bet it's a poor IVTC process w/ bad cuts/joins, etc.
--> use select None, else w/ Forced Film at your own risk

When its:
---------
Video Type: NTSC
Frame Type: Interlaced
* you can bet it's a PURE Interlaced (every frame is interlaced)
--> use select None, and do NOT use Forced Film
...... test this in either vdub, or TMPG's source range, using mag set
to 2x or 3x and see if each frame is distorted w/ lines or horible looking
bars.
## If every frame is lined, then yes, as I said, its PURE Interlaced,
and you should encode w/ Interlace under both tab in TMPG or,
## choose a de-Interlacing method that works best for you in
.......... producing a Progressive source, for PC viewing, but can also be
.......... view on TV as well.

also, did the same problem occur on your computer as well as the dvd player???

if so, my best bet is that the source is NTSC interlaced, which means you CANNOT use forced film in dvd2avi

in tmpgenc, u can do either 1) IVTC and encode as 23.976 fps + 3:2 pulldown or 2) encode as 29.97 fps + interlaced

the latter will not play very well on computer because the monitor is progressive and your video would be interlaced..however, interlaced TV will play fine. in addition, latter will be of lower quality cuz more frames to share bitrate...however, the latter should be easier to do and you can bet there will be NO interlaced lines on the TV

poopyhead,

yes, thank you. I knew I left one more out.

nandi,
I've revised my post above. Have a look and see if this is one of yours.

Thanks Guys
But doing all that you said, I got huge comb lines in some of the fast action scenes (the dude sort of bounces around alot ) when I played it on my stand alone dvd player. I have an Apex 500w, btw. The svcd also speeds up or slows down sometimes, but gets back into sink. I don't know what the deal is.

[poopyhead]

did you turn on forced film in dvd2avi? if the movie is NTSC interlaced, u have to turn OFF forced film

[nandi_nokuri]

I don't think it's so much interlaced lines. Because they don't show up on my computer monitor. I think it might be tmpegnc. I have never made a interlaced svcd before, al my other svcds where Ivtcd.

Nandi, what did you find when you did the preview with DVD2AVI? It's important to figure out what type your SOURCE file is. Follow VHelp's instructions. Open the VOB in DVD2AVI, and press F5 to preview. Note the Video Type, and Frame Type.

You may have to re-do your encode, using Force Film to remove the pulldown flags in your source, depending on what you find with the preview.

You may have to re-do your encode, using Force Film to remove the pulldown flags in your source, depending on what you find with the preview.

it may not be a good idea to force film if the movie is NTSC. the resulting mpg will be jumpy and have horizontal lines.

Which is why I said "depending on what you find with the preview". We still don't know what kind of source we're working with. Until we do, any advice we give could be bad.
