Can you see Flim vs NTSC different ?

[SingSing]

I am doing all DVDrip to flim rate SVCD.
I see interlace artifact on some takes.

Is this due to flim rate playback on NTSC TV ?

It depends on how your ripping the DVD. If your using DVD2AVI, it should tell you what type of source your dealing with. Does it say FILM?

If so, use the FORCE FILM option to ignore the pulldown flags. The ripped file should be progressive with no interlacing artifacts.

unless the movie is completely 100% FILM, there will be parts of the movie that will have some NTSC character, which may result in some very minor horizontal lines.

just use the de-interlace filter to remove ... best setting is blend (adaptive) or double (adaptive) depending on which version of tmpgenc u have

[DJRumpy]

It's not likely. Most newer DVD's are in progressive film format, and IVTC'd in the player.

Some of these Disc are not 100% flim.

Snow white suppose have quite a bit of NTSC,
but it just look artifical, and not more interlace.

The DVD horizontal is 704, SVCD is 480.
Does de-interlace is recommandated becaused of this different ?

i did snow white region 1 using forced film. there was no problems. if you get occasional horizontal lines, de-interlace filter will be good. if after you forced films, the horizontal lines are everywhere, then you prolly need to redo the movie w/o forced film

Yes, that what I saw, but I read r1-snow white is same
as Beauty and the beast, has quite a mixture of NTSC.

I only can see the interlace artifact on 50" projection TV,
they look like short little gray bar on the right of an object.

Yes, without force flim rate, will add a lot long white
lines on the video.

i don't think you're quite understanding me...

i recently did beauty and the beast (it was 99% FILM, which only leaves 1% NTSC)...however, it switched from progressive to interlaced..... i was able to force film (which resulted in lots of lines) but used de-interlace to remove them w/o any problems (no jumpiness)

however, if the movie is 10% NTSC or greater, you may need to turn OFF force film and either 1) IVTC and encode as 23.976 fps + 3:2 pulldown or 2) encode as 29.97 fps + interlaced

counter to what you said, if you force film on a NSTC source, it will add lines....in this case, turning off force film is part of process to remove lines

I forget the rule of thumb. I think Adam posted it last. Anything above 70% usually looks fine (Adam?)

hrm??? i've seen websites that suggest force filming only for movies with 95% FILM or greater...i was being more conservative by saying 90% FILM...but i've seen movies with even higher (i.e. man in the iron mask had ~96% FILM and there was short segment that acted like it was nearly NTSC...very choppy and interlaced lines everywhere when i tried to force film)

a way is to force film most of the time (unless it's really obvious like dvd2avi indicating high percentage of NTSC) and then checking the results to see if the video is jumpy and has lines everywhere...if it does, then force film prolly isn't good idea despide being pretty high FILM percentage

[adam]

The general rule is %95 or higher film, but the exact percentage is really pretty irrellavent. The opening and closing credits are almost always pure ntsc, and at the most will account for %5 of the film, which is where that % of ntsc comes from. If you did have some abnormally long credits than its conceivable that you could have as little as %90 film listed in dvd2avi and still have a pure film source for your actual movie. In any case, if the movie isn't mostly film than it should be pretty easy to tell. The vast majority of ntsc dvds will be %95 or higher film. The handful that aren't will be pure ntsc or the % will fluctuate greatly as it previews or will be very low, like %30.

I use Force Film, SmartDeinterlace, or MaskedDeinterlace with AVISynth and the MPEG2DEC plugin with good results on lower percentages. Motion seems to be smooth, with little, or no jerkiness.
