Need help determining between interlace and noninterlace

[photojoe]

I put my ripped DVD movie into DVD2AVI before sending it to Tmpgenc to encode as a backup to my original. In dvd2avi it says its a FILM, 16:9 and 29.970fps. Tmpgenc asks if its interlaced or non interlaced by looking at the stats in dvd2avi, but how do I tell based on this info if its interlaced or not.??? It says its FILM 99%. Doesnt say interlaced or not. Is there something I missed or is there a setting I should be clicking on to tell me what it is? I'm in the U.S. and will be viewing this on a NTSC type tv. Please set me straight on this, so I can move on. I see under field operation in dvd2avi there is force film or none. its set on none now, should I change this for a FILM movie to force film or leave it alone?
Thanks

movie is 99pcnt film so set dvd2avi to forced film

You'll find that the frame rate shown then displays 23.976 and that the number of rames coded is close to the number of frames played (hit F5 to let DVD2Avi run thru a few mins of the footage and then hit Escape the statistics will show Frames coded and frames played)


if the footage was interlaced but you'ld set Forced film on then the number of frames coded would be far greater (20 pctn or so) more than the number played) in the statistics panel

opposite is also true - if the movie was filmbut you fail to set the forced film option then number of frames coded would be around 20 to 25pcnt LESS than number of frames played

99pcnt rating usually means the movie has a few secodns or so of interlaced at start might be opening title in which case you could trim it off, might be whole ofthe opening credits sequence in which case your stuck with it

the awkward ones are where it bounces back wards and forwards from film to NTSC at varous points in the movie as it'll be a mixed hybrid clip (bit of both in it at different points in movie) But id expect a lower film value than 99pcnt if that was the case

Thanks for the info, wow you so far have set me straight on this and cleared things up a bit. I'm with you so far, but what settings in tmpgenc should I put for a movie that's forced film at 99%fillm and 23.976fps?
example, do i set fps rate at 23.976fps(internally29.970), and ecode mode to 3:2 pulldown on playback? And then under the advanced tab, as tovideo source type, interlace or noninterlace progressive? and do i use any filters such as deinterlace? Then under GOP tab, do I select force picture type setting and detect scene change? These options confuse me as to which ones I need and which arent really necessary. I need the finished dvd to play on my ntsc tv. What do you think, now that you got me through dvd2avi, how about getting me through tmpgenc?

for a film type stream Id keep the tmpeg side simple:

just let it encode it back out at same 23.976 rate then manually run pulldown.exe on it to set the pulldown flags on the new version

for TMPEG source it'll be ntsc non interlaced (progressive)

Just have the GOP tab detect scene change leave everything/anything else in GOP settings as standard

aspect ratio will be down to the clip but again as with above Id keep it simple have tmpeg treat it as 4:3 and then (if its actually widescreen) adjust the final output ifo files using ifoedit (after you've authored it as a DVD title set with whichever app you're going to use for authoring) some apps you'ld end up having to do that anyways
