Sefy, can you plz help me with interlaced NTSC movies?

[poopyhead]

NTSC encoded DVDs, i.e. Chris Rock: Bigger & Blacker and some Hong Kong dvds are purely NTSC.....blend (or double) de-interlace filter removes all the lines but apparentely also some vertical resolution, which causes the rip to be very, very jumpy and not as sharp

any help Sefy...also i tried using the auto-set inverse telecine in tmpgenc and it didn't work...so any help?

[Sefy]

Have you tried encoding without adding any filters ? sometimes the jumpiness comes from using an incorrect Order Filed in TMPGEnc, try changing it before doing any encoding.

[poopyhead]

i need to get rid of the lines, so without the de-interlace filter, the rip isn't jumpy but there are lines everywhere (and i mean everywhere)

[Sefy]

Can you send me an email with a snapshot (JPG image) of those lines, it sounds very strange that DVD rip would do it.

[poopyhead]

hey sefy, dumb question, but i'm having trouble making a snapshot of the rip....print screen doesn't seem to work when i play it on media player or winDVD and then pause it and then print screen it and paste it on MS paint or MS word.

[Sefy]

Do you have Paint Shop Pro by any chance ? you can use that to do the Screen Capture, and save it to any format you want.

[poopyhead]

Sefy, nope don't have that program. can i e-mail you a short clip of the rip with all the fucked up lines instead...should be less than 1 meg?

P.S. the NTSC that i'm referring to is the video type that dvd2avi displays...not the NTSC that we put as source aspect ratio in tmpgenc cuz all region 1 DVDs suppose to be NTSC...but most are of type FILM as in dvd2avi...but just some DVDs are purely NTSC video type

[Sefy]

Usually for Film based DVD's you can use the Force Film option in DVD2AVI, although i've never used that option, it could be good for you, as for sending a clip, unfortunatly my email is very limited, but if you got ICQ you can send it through

[poopyhead]

sup sefy, i'll be on ICQ and i've already added u to my contact list...hopefully my ICQ should auto-send the clip that i'm talking about...

[Sefy]

That is weird, I didn't get any message that anyone added me, you sure you added me ? my ICQ is 10489780

[poopyhead]

hey sefy,

i encoded it your way, SVCD NTSC template w/o forced film....got rid of all the interlaced lines and no jumpiness...at least in the short clip i did...i'll let you know the results after i've encoded the entire movie

[Sefy]

Well, you gotta admit that's already an improvment

[poopyhead]

thnx for all your help, sefy

[poopyhead]

hey sefy, you wouldn't hapeen to know if encoding using regular NTSC SVCD template at 29.97 fps nonFILM is lower quality than FILM 23.976?

[Sefy]

I don't see why would regular SVCD NTSC would give lower quality then SVCD Film, actually I think NTSC will give higher quality since you got more frames, and more frames means smoother movie.

[poopyhead]

i would think so too, but this is a quote from luke's video guide at http://www.geocities.com/lukesvideo/

---------
Fortunately, it is usually possible to undo the telecining process and convert a video back to its original 24 fps state. This removes most of the interlacing artifacts, makes the video play more smoothly, and decreases the file size of the video.
--------

He says that 24 fps plays more smoothly than 30 fps.

[Sefy]

From what I saw for myself, unless the movie was pre-made as NTSC Film, the playback quality is very choppy in my eyes, and I don't think the file size will be smaller, i've encoded the same movie twice, once as NTSC and once as FILM, and file size was exactly the same, the reason I believe is because FILM has to add the 3:2 Pulldown so it will actually be played as NTSC.

[stanwebber]

filesize is determined solely by bitrate....fps & resolution have nothing to do with it. although luke's statement is misleading, it is essentially accurate except bitrate needs to be lowered by 20% compared to a pure ntsc encode

[Cart Wheel]

Sorry to butt in , but how is that misleading? I said that if you have a 29.97 fps telecined movie, and you inverse telecine it to ~24 fps, it will play more smoothly on a computer. The file size will also decrease (with quality based encoding). Obviously, the file size won't be affected with constant bitrate encoding. Maybe I should have explicitly stated that?

Sefy is absolutely correct in that if your video is truly NTSC (i.e not telecined), you don't want to use a Film profile. Maybe I wasn't clear that I was talking about telecined video (video from a ~24 fps source, such as a film).

Sorry about the confusion,
Cart

hey sefy, sorry it took so long to respond...but wut you told me completely worked....no lines and no jumpiness...

for those of you that make your output video "interlaced" or use "inverse telecine" make sure you select the correct field order...apparently the field order does not matter dealing with non-interlaced (progressive) video...but if you plan on making your output video interlaced or use inverse telecine, then make sure you select the correct field order

i encoded and burned a dvd rip with the wrong field order, but i didn't notice it on my computer monitor cuz it's a progressive display...however, on the TV (interlaced display), the wrong field order leads to jumpy stuff...

btw...thnx to luke's video guide for explaining interlaced and progressive video

[Sefy]

poopyhead, i'm glad to hear the problem is solved, after all, that's what we are here for, to understand and help solve
