Do I need to enable Force Film in DVD2AVI??

[Gideon30]

I have a DVD that I am ripping, and the statistics show it as a NTSC format, and the FPS as the 23.976. I am just overloaded with information from here, and the guides, and am not sure what to do with it. Do I need forced film enabled or do I do nothing, and just encode it at 23.976? Also, do I need the 3:2 pulldown?

I am just talking about for me, not stating this is the correct way to go about this..BUT, for all my american made NTSC DVD disks...I always do force film and never have had any problems with viewing....the theory being that at 23.976 fps, you can allocate more bits per frame during encoding & thus come out with better quality....and when I encode, I always set my source AND output to "NON-interlaced (progressive)"...with 23.976 fps as an output framerate as well....and I have no problems during play back on PC or standalone....it has been said that your standalone/TV will always output at double the rate...so 23.976 gets transformed to about 48 fps, where 29.97 is about 60....perosnally, my eyesight isnt the greatest, but I can't see the differences in 12 fps...in the end, its a judgement call.

You dont need to set any of that... Just Save Project and let TMPGEnc do the rest.

ummmm thanks for posting something that had nothing do with what was asked...the app he was asking about was DVD2AVI, not TMPGenc

[pinoy2201]

i suggest to try it and try it with out the force film on DVD2AVI and encode it and check what looks better to your eyes

Nice comeback kdiddy, luv ya too! Since the objective was not specified, I assumed he was going to VCD, hence the URL vcdhelper.com I may have been off track, or the poster may have been.. Either way maybe some confusion that didnt concern you or require your 3 cents.

If posters would be specific and state there objective, then ask the question it would be much clearer for everyone.

Gideon30, what exactly are you wanting to do, and we can guide you better, without retort from others.

Here's the background and info you need. You TV displays 29.97fps of interlaced source. Interlace means that each frame is actually made of two fields (odd & even) which have 1/2 the data. This is due to a historical problems with TV.

Movies are shot at 23.976fps progressive. Progessive meaning that each frame is a complete still of the movie. In order to show a 23.976fps progressive movie on your 29.97fps interlaced TV you need to convert it to that format. This is done by a process known as telecine (aka 3:2 pulldown).

Now when you play your DVD it's 29.97fps. And that's what you rip. Now if it was shot at 29.97fps, just leave it alone and encode as normal. But if it was shot at 23.976fps you'll want to convert it back to that.

There are two ways to do this. Either click force film in DVD2AVI or run an inverser telecine process (aka IVTC). The thing is IVTC is REALLY slow. So forcefilm saves time and still produces a 23.976fps progessive source (I'll skip the argureements about which is better).

Once you've encoded the 23.976fps source you'll need to telecine it to play it on your DVD player/TV. In TMPGenc just use the NTSC_Film template (this will add the 3:2 pulldown flag to the MPEG). For CCE just encode the a 23.976fps mpv file, run pulldown, then mux.

Hope this clears it up some

Did even read the title of his post1!?!?!

"Do I need to enable Force Film in DVD2AVI?? "

what part of that confused you??...dont get salty because your dumba$$ messed up and read more into what was asked....he ask a vague question, give him a vague answer...THEN he will learn to get more specific.

and again im not so sure that a 3:2 pulldown is needed, I do forcefilm, encode 23.976, and it plays fine on my NTSC region 1 DVD player & TV...now I have been told that this happens because most (NTSC, U.S.) DVD players automatically preform a 2:3 playback when they detect 23.976 video....I dont know the validity of this, all I know is that it works on my DVD player.

It's real simple. If possible you want to keep your film at ntsc film if its already like that. You cannot use force film everytime, it wont work on some dvds. So fire up dvd2avi and preview it. Make sure you get past the beginning logos or credits and into the movie. If in the statistics it says %95 or higher film that force film will work perfectly. If it is slightly less then it will still work but you might see interlacing during certain scenes. If it keeps starting over at %0 than force film will not work. In this case disable force film and if you want a quality rip you will need to do an inverse telecine during encoding, otherwise just encode to 29.97fps. If you are making a svcd and encode to 23.97fps you MUST include the 3:2 pulldown. Some dvd players can play the svcd properly without this but most can't. If your making a vcd you dont need the pulldown but not all dvd players can play ntscfilm vcds, even though its a supported format.

Vejita-sama: film isnt shot at 23.976fps, standard film is shot at either 24fps or 25fps. 23.976 is just what they slow it down to before performing the telecine to get it to 29.97, otherwise the math don't work.

As what adam said.

SVCD only supports 29.97 fps video for NTSC. If you encode your movie at 23.976 fps, you must include the 3:2 pulldown tags.

VCD supports both 29.97 fps video (NTSC) and 23.976 fps (NTSC-FILM) so you don't need (and shouldn't!) use 3:2 pulldown. As adam stated though, not all stand-alone players will play NTSC-FILM VCDs although they should.

If you are creating a S/VCD from an NTSC DVD, you should try to keep it in NTSC-FILM if possible. Not only will you be doing less encoding, the end result will also look better (relatively increase of 25% bitrate per frame).

Regards.

Yo Kdiddy/Penisless, go back to the URL, VCDHelper.com.. I say again..

Nevermind...
