    Hi

    i want to put 4 VCD movies onto a DVD, they are all avi files, but only 1 of them is 29.97.

    so i need to make the other 3 NTSC FILM avi files into NTSC Video VCD files so that i can add them to my DVD.

    i tried encoding them using NTSC instead of film with tmpeg but it looks a little jumpy when played on the tv. And trying it with 3:2 pulldown, gave lots of vertical lines showing during motion.

    any ideas.

    Barrie

    baz161,
    I think I understand what you are wanting to do. In fact, I have consolidated a number of my VCDs onto DVDs. I typically can get three(3) VCDs onto one (1) DVD. To do this, I do nothing to the video (most of my videos are XVCDs) and only resample the audio by demuxing the vcd, resample the audio and then mux them back together again, keeping them as MPEG1 files.
    I load them into TDA as separate tracks, add a simple menu system and burn.
    So far I have not had any problems at all. I one case, I mistakenly forgot to resample the audio but in the end it worked anyway, so I never bothered to resample it. But the sound was not as good as it could have been but good enough for what I needed / wanted.

    yeah thats exactly what i want to do, ive made many of them before, but with them all being pal, there was no problem

    i am using tmpeg dvd author and in this case all the movies are NTSC, the problem is you cant make a dvd with 23.976 fps files, it only accepts 29.97 fps.

    its really useful, i can put 3 or 4 movies on, with menus and chapters etc, all on 1 disc.

    so i need to make the files i encode 29.97 (vcd standard) from 23.976 source files (avi), any ideas?

    I am from the wonderful land of Oz so I am by no means familiar with NTSC, but as I read it, there is no need to do a 3:2 pulldown on MPEG-1 because the 3:2 pulldown is only supported by MPEG2. I would use TMPGEnc DVD Author and place each clip in its own track, leaving the files exactly as is - There is no need to re-encode if they are already valid VCD files. It will resample the audio for you.

    [EDIT] Re-read one of your posts and I now concur - TMPGEnc DVD Author will only accept 29.97fps MPEGs as you state.

    My bad !
    If in doubt, Google it.

    AFAIK, DVD requires NTSC to be 23.976fps with 3:2 pulldown or 29.976fps. As mpeg-1 does not support 3:2 pulldown you are out of luck, you will have to re-encode. Use a slightly higher bitrate (1500kbps CBR or so) in an attempt to maintain quality as much as possible. (29.976fps is more frames, so needs higher bitrate for same quality).

    thanks, but thats not exactly going to work, let me explain.

    I have an avi file, with a frame rate of 23.976.

    I then use tmpeg enc to make a vcd mpeg file. If this was for a vcd i would use the NTSC FILM (23.976) option and the vcd would be perfect.

    however, if i encoded with that option Tmpeg DVD Author would not accept this file as it will only accept 25 fps or 29.97 fps.

    so when i encode in tmpeg enc i take the NTSC (29.97) option. This gives me an mpeg file that TDA will accept, and when encoding i changed the audio from 44.1 khz to 48 khz so its the correct sample rate already.

    However when i play the DVD, the movies dont look too great infact a little jumpy. I imagine this is because im an encoding to 29.97 fps file from a movie which is originaly 23.976.

    Is this the case? if so can anyone suggest what to do.

    thanks to everyone for taking the time to answer this,

    Baz

    bugster, thanks, u know what im talking about,

    so u dont think theres anything else i can do, i can up the bitrate to about 1400 before i run out of space, is that the only thing i can do?

    cheers

    You are not doing what bugster recommended and you mustn't have read my edit in my first post.

    You need to load the NTSC DVD template, set the fps to 23.976 and on the Video tab, set the "Encode Mode" field to "3:2 pulldown when playback". Do not use the tickbox on the advanced tab.

    It has been a while since I have had to re-encode NTSC files, but trust me, this works.
    If in doubt, Google it.

    yes i am doing what bugster suggested and yes i did read your post.

    what you just suggested is infact what i do when making mpeg 2 files when i need to change 23.976 to 29.97.

    but i am making mpeg 1 files and from what im aware you cannot set the "Encode Mode" field to "3:2 pulldown when playback". can you? i wasnt aware you could.

    You are right, mpeg-1 does NOt support 3:2 pulldown. As your source is avi (not VCD format mpeg-1 aleady which I had presumed) you have a couple of options.

    Encode to VCD resolution at 23.976fps but use mpeg-2, thus allowing you to use 3:2 pulldown. I am not 100% sure that this is DVD compliant but it is worth a try. Stick with around 1100kbits/sCBR bitrate.

    Encode to 1/2 D1 (352*480) and up the bitrate to about 2500kbits persecond, mpeg-2 with 3:2 pulldown. This is definatley DVD compliant, but your files will be bigger than using VCD res and bitrates.

    Why were you locked in to using MPEG-1 ?

    because i wanted to burn them as vcd's aswell for my uncle, he doesnt want any dvd's just vcd's so he can easily make back ups. although its a non standard vcd because of the 48000 hz audio hes happy with that as its better quality and his dvd player copes with them no problem.

    that way i kill 2 birds with one stone so to speak, i just split it and burn the vcd, and its quicker encoding mpeg 1 than mpeg 2. So it was more the logical choice.

    Fair enough - whatever floats your boat I guess.

    Unfortunately helping out your uncle won't help yourself though !

    I don't think there is any way to kill the two birds with the one stone unless your uncle's DVD Player plays miniDVDs. Then you could just encode the one MPEG-2 file, compile it with a couple of ther files and author for yourself, and just author it on its own for your uncle.
    If in doubt, Google it.
