  1. there are tons and tons of forum posts here about what to do with converting avi's to mpeg1/vcd types

    but a few are getting the newbies soooo confused its starting to bug me, hence this post,

    now a few "experienced" peeps are possibly gonna reply to this , then fair enough all im gonna post is what i use and have NO probs, converting avi's, so here goes

    (i spent nearly 6 months trying to work out how to convert using dvdrhelp/vcdhelp.com and thanks to those guys that put me on right path)

    1st load the codecs found on the left under tools

    progs i use

    virtual dub
    avi uncompresser (so many peeps need this, but not a lot know it)
    tmpgenc

    what alot of people try to do is load in avi straight into tmpgenc, some work some dont,

    avi's are compressed (divx, xvid etc, and normaly the sound side of it)

    and then tmpgenc sometimes has errors encoding,

    what i do is uncompress the avi,

    the uncompressor i use can be found here

    http://www.mnsi.net/~jschlic1/

    very easy you load it up load the avi , hit decompress

    it creates an uncompressed avi file (if your avi was called film.avi the new file will be named film_pcm.avi)

    then i strip the sound using virtual dub

    i wrote a word doc how to do it all encoding to vcd/mpeg1

    goto www.data-uca.150m.com/vcdencoding.doc

    anything you need please read the soooo helpful bits on left or email me at mat_stuff@hotmail.com and i will help as much os poss

    I really think you are on the right track. Have you considered posting a guide? The link to your page is inop.

    @matneaves,

    your posting is all about problems importing cetain AVI files to certain encoders. With the amount of codecs available, it's easy to mess things up and end up with an AVI file that Tmpgenc, or other encoders will not read. So your approach is on the right track.

    However,

    I am puzzled why you need to use an "uncompresser" codec with VirtualDUB to create an uncompressed AVI file. I can understand this codec's existence as some programs will not allow you to save uncompressed, but VirtualDUB has the option to "SAVE Uncompressed" for both video and audio. So, if you need uncompressed audio only, save video in direct stream copy mode and audio in full processing mode with no compression.


    Video is a bit more difficult. For small files, saving in uncompressed format is ok. However, for large movies (>1 hour) it's impractical for most people with rather small HD. A two hour uncompressed movie in DVD resolution has a size in the range of 200~220 Gb. The only way to fit it would be to have a striped volume of two disks of 120Gb or more each. Not many people have it.

    Additionally, saving a video file in uncompressed format is a punishing option for speed. The data rate is so high that writing or reading the file is very slow.

    A better alternative to fix codec compatibility problems might be to use hufyuv codec in high compression mode. This is a rather fast, compatible and lossless to very little loss codec. Doesn't make very small files but the two hour movie would be in the 80Gb range, which is manageable.
    The more I learn, the more I come to realize how little it is I know.

  4. damn, the link seems to be working for me, ah well

    if anyone wouold like me to send them the doc, then email me at mat_stuff@hotmail.com

    sasi

    the reason i sometimes use an uncompresser with vdub, is because if i dont then vdub brings up a message saying



    but after i decompress the file, and try to load the film_pcm.avi back in i never get an error and there is no sound sync probs at all

  5. in your guide you are asuming that everybody use ntfs patitions,
    if you do use ntfs patitions then you have no problem with the big avi
    file.

    but if you use win98 or me, you hit the limit of 4GB, and now you have
    another problem...

  6. none of my uncompressed films are over 2 gigs, usually 1.4-1.7, and the stripped wavs are never over 2 gigs

  7. then its not uncompressed
    there is some kind of compression here, otherwise you whould have ended up with bigger files.
    and if so, is it realy lossless?
    or do you actuly loose more qulity?

    im not trying to bring you down or something,
    its just that i want to understand whats going on.

  8. no probs,

    there possibly could be a small amount of compression somewhere but all i do is load the decompresser and uncompress the sound creating a blahblah_pcm.avi then use that and the stripped wav from it into tmpgenc

    Hi,

    Can you please email your guide and avi uncompressor to me.
    The links are not working.

    Cheers.

  11. matneaves, I don't want to pi** on your bonfire but it seems to me that in most cases you are wasting time and disk space. As you appear to know, decompress.exe simply decompresses the audio track within the avi, not the video. This can be achieved at the same time as extracting the audio using virtualdub, simply by selecting audio->full processing, audio-compression=none and save as wave. About the only time this may result in problems is when the audio is a VBR mp3 track. In this case vdub-mp3 (a modified version of vdub) will work fine as will goldwave.

    Having said all that, I agree with the other posters that say
    if it works,it works.
    as long as you are happy with what you end up with.
