    Tried DVD shrink on a converted MP4 to Dvd and it was a huge file.
    Either I am doing something wrong, or it isn't working.
    I checked the "pre-shrink" file size with the "post-shrink" file and they were both the same size.
    Anything thoughts??
    Thanks...

  2. Shrink is for reducing the size of DVD's only. If you convert a DVD to MP4 you control the size of the MP4 through the conversion software by choosing the bitrate, resolution...

    I'm surprised Shrink even tried - without kicking the file out as unrecognized.

    Or you simply do not understand what DVD shrink does.

    Ok. We know nothing about your mp4 but I will, for the sake of an example, assume it runs for 90mins plus. Convert that to a tidy dvd bitrate and you get a 6 gb+ dvd.

    DVD shrink will attempt to convert that 6 gb dvd to allow it to fit on a standard single-layer blank dvd. The file size will still be about 4.3 gig and somewhat larger than your original mp4

  5. You can set the target output size in DVDShrink's preferences. It's set to DVD5 by default (single layer DVD size, or about 4.5GB). If the total size is already the same or less, by default DVDShrink won't try to shrink it any further. Only if it's greater than DVD5 size to begin with.

    You are doing something wrong.

    You don't say what the filesize is (before or after). If the before combined sizes was less than 4.37GB, it won't NEED to shrink, so it won't.

    So I need to try a larger file than 4.3 for it to shrink?
    Was hoping to put several files on one disk

    Are you trying to put several MP4 files on one disk? If so, DVDShrink is the wrong type of app.
    This shrinks an an already authored DVD. This will take a DVD disc with menus and extras and attempt to make it smaller.
    Or re-author a disk and remove extras.

    If you have a number of files you want to cram on a disc use avs2dvd or convertxtodvd to author them properly.

    I tried converterxtodvd the free version and either I didn't use it properly, or after conversion the files stay stored on converter x as I couldn't seem to find how to save them to my hard drive, or transfer them else where, and after a search the computer couldn't seem to find them either.
    Maybe the paid version is different..?

    Did you assign a save location in the setup? Otherwise it will have saved the AUDIO_TS and VIDEO_TS folder in My Documents/ConvertXtoDVD which is the normal default location for this program ......... or did you set it up to burn to a DVD?

    I set the converted file to a folder, unless there is some obscure setting that I missed..
    I have some very large MP4 files I was hoping to convert to DVD-413,000 KB ( not sure exactly what that is in MG )so once converted it would be huge.
    I realize I may not be able to put everything on one disk even if I have a dual layer and shrink it..
    Not sure how to put it on 2 disks either...
    Thanks for the help..

    When going to DVD, you should already know what the limit is: 4.37GB (SL) or 7.95GB (DL).

    That, armed with the formula: "filesize=bitrate*runtime", and the fact that there are bitrate limits for DVD (~1-9Mbps) means you already can figure out the range of quality vs. running time of your combined source files.
    <1 hour = excellent quality
    2 hours = normal, decent quality
    3 hours = fair, acceptable quality
    4 hours = compromised, poor quality
    5+ hours = crappy quality
    (Almost double this for DL discs)

    You pick.

    Everybody has their own definition of "quality"
    100 minutes on single layer DVD was the limit for me on CRT TVs.

    Totally agree with you: that's why I used the "~" and "range", as there is quite a bit of room for variability, in both the user's expectations and in the encoding efficiency and in the type of content.

    But the OP needed some kind of starting point.

    Sounds like it would be better to put larger videos on several DL disks instead of trying to shrink them.
    is that easy to do?
    I was told Nero was a good converter, would that split videos properly too?
    Thanks for all the info. I am definately learning as I go...

    Several discs makes more sense than too much shrinking, yes. Easy? - relatively. I don't know what you'd consider easy.

    Nero is NOT one of the better converters, but neither is it total garbage.

    If you are using DL discs you can stay with convertxtodvd:
    under Settings->Encoding set 'Target size' to DVD-9 and just use two (max. 3) movies to convert.
