  1. DVD LAB allows this but not for what I want (mpeg1)

    I want to burn mpeg1 44khz audio to dvd WITHOUT converting the audio to 48khz.

    this means I need a program that will process an mpeg1 and make me vobs and burn these to a dvd AS IF they are legitimate dvd mpeg1 (48khz) files even though they are not.

    IE I DO NOT want to convert them. I know this is outside the dvd spec. I don't care I want to try !! I am very confident they will play "just fine" if I could actually make one.

    example. my digital camcorder (hitachi mpeg10w) captures mpeg1 directly to a pcmcia hard disk. they are not proper mpeg1 SPEC files.

    instead of 224kbit 44khz stereo (22khz per channel) they are 224kbit 32khz MONO audio.

    now when I drop this onto nero it says this is not a vcd compliant mpeg1 vcd file. do you want to convert or ignore and burn anyway.

    I say ignore and burn anyway IE it treats it like a compliant file and DOES IT ANYWAY without any conversion whatsoever.

    guess what. ANY dvd player that properly plays vcd also plays these "illegal" vcd's just fine. not one problem yet.

    I want to do this for DVD-R's I want an authoring program that will allow me to say yes I know they are not proper DO IT ANYWAY like nero does.

    how do I do this ? there HAS to be a way to do it. dvd movie factory converts the audio but it ALSO converts the video for some reason (degrading it greatly !!)

    I want to TRICK it (or any program) into using the files UNMODIFIED. how do I do this ?

    is there a program that will let me spoof the file headers so it thinks IT ALREADY is the proper dvd mpeg1 format ??

    I just want to TRY IT and see if it works. as long as they can actually READ the discs dvd players are surprisingly flexible on what they will read.

    right now I just dump the mpg's onto a dvd-r as data files. works fine in my players but some players that will play mpeg1 fine can not play them simple because they are not set to read iso data discs for mpg's etc.. so if I could encaposolate them into a dvd-video disc so it thought it was legit I am betting it WOULD in fact play them just fine.

    right now it takes 6 HOURS to convert the damned audio to compliant format which is crazy. I gave up doing it (hence why I make iso data discs and just plop the mpg's on it)

    but for some stuff I WOULD LIKE to make Menu's etc.. I just need a way to try it into accepting my mpeg1 files as if they were already 48khz audio,

    suggestions ??

    so to sum up I am looking for one of 2 things.

    I really am not interested in hearing it can not be done. anything can be done. all ulead had to do was what nero did for vcd. allow me to OVVERIDE the conversion and force it to burn anyway.

    now whether or not it will WORK in a dvd player is another issue. I am willing to waste a few 70cent dvd's and a few hours of playing around to find out. the payoff if it works is hundreds of saved hours of work and cooler home videos !!

    I want either 1

    a way like nero. to author a dvd and force the program to use non compliant files.

    or 2

    a way to ALTER the files to spoof programs like movie factory into thinking they are legit files and using them as such IE no conversion.

    suggestions ??

    PS just an FYI to the curious. WHY do I want to do this so badly ?

    I have been using this camcorder for over 4 years now. I have HUNDREDS of gigs of home video (I take pictures and video of EVERYTHING its a hobby) the family hates it but too bad :-) to me its history and I want to preserve it.

    I even stopped using my dv camcorder since they LIED in advertising that you could download via firewire. you can not you RERECORD via firewire. I will keep using my nic empeg10w till it dies and I can not get another one. takes me less than 20 minutes to transfer 2 hours of video from the card to my laptop. I like it and I can burn direct to VCD now I want to burn direct to DVD.

    the hard drives to HOLD all of this is expensive and I have had HD's fail.

    I want to make Nice pretty dvd's from them. nice menu's with music and stuff. this is FUN to me. I usually fill a dvd (7.5 hours of video)

    it takes 6 HOURS to convert the audio to 48khz. and for whatever reason it does something to the video as well making it look worse.

    all I want to do is burn mpeg1 to dvd format WITHOUT converting. if it does not work so be it I will live with it. but I think it will work and just want to try it !!! :-(

    any help would be greatly appreciated.

    OK.

    I can understand you wanting to be adventurous.

    But, for a moment, let's think about the main problem that pushes you over the border.

    6 hours to re-encode audio.

    There's something really wrong here.

    With a P4 machine, it should take well under 5 minutes for an hour's worth of audio.

    You did not explain what s/w you are using to encode, but I guess you are using Tmpgenc. And I also guess you are encoding both the audio and the video as well.

    Are you starting with an .mpg file that has video encoded as MPEG-1 ? If so what is the frame size of the video? Is it acceptable? Does it have the correct GOP structure to be used in a DVD? If not, even if you foul the authoring program to accept it, you will have tons of problems seeking, setting chapters and eventually with video/audio sync.

    So, if the video doesn't have the correct structure, you will either have to re-encode it or use a tool to add sequence headers and gop headers every 20 frames or so.

    To re-encode you need an MPEG-1/2 encoder. OK, Tmpgenc is not very fast for full DVD resolution. MainConcept is many times faster. However, Tmpgenc is free for MPEG-1 encoding. If you use filters and select the highest quality motion search mode, then Tmpgenc is slow.

    Now, about the audio.

    You mentioned that the audio is recorded at 224kbps 32kHz mono.

    There are various ways to re-encode that.

    One way is to open the .mpg file within Tmpgenc and select the output to be ES audio only. Then set the appropriate bitrate you want (I would use 192kbps) and 48kHz sampling rate. Tmpgenc should encode that pretty fast.


    I've made the above comments out of guessing about the tools you use and how to proceed. Please post more details so I can be more precice.

    Rgds.
    The more I learn, the more I come to realize how little it is I know.

  3. well I am encoding 7.5 HOURS of video at a time usually since that is what fits on a DVD.

    just for the heck of it I tried something more compatible. dvd rip to mpeg1

    352x240 29.97fps 1150kbit cbr with 224kbit stereo 44khz

    the only different that I am aware of between this mpeg1 vcd video and mpeg1 dvd video is the khz of the audio it needs to be 48khz

    I tried just letting movie factory handle it but I think your right I think its converting the audio AND video (since the video looks more compressed when its done with it)

    I could plex the audio and video and then convert the audio (simple tool to do this ???) but that is what I did not want. MANY MANY "user involved" steps in order to get it done :-( I want a one step tell it what I want walk away and its done when I get back kind of thing. I tend to let it run overnight so in the morning its all done.

    maybe its taking so long because it really is converting the video as well. but I tell it not to convert compliant video ???

    Suggestions. assume I have NO software. what should I use for the most painless means to get the audio to 48khz like the dvd software demands ??

    Thanks
