Shrink DVDs down to size with Amok DVD Shrinker


Amok DVD Shrinker is a free program that can compress decrypted DVDs to smaller, user-defined disk sizes without any noticeable reduction in quality.

It is designed to enable the copying of commercial DVDs stored on nonstandard media in order to fit them on a standard 4.7 gig writable DVD.

Imagine the following scenario: you’ve just successfully decrypted a DVD and copied it to your hard disk, but when you try to burn it to a DVD you realize that the decrypted data exceeds the 4.7 capacity of your burnable media and will not fit.

If this has happened to you then Amok DVD Shrinker is what you need. Not only will this program quickly and easily compress the DVD on your hard drive into any size that you want with no apparent loss in quality, but it will also preserve all the elements of the original including menus and extra features (or, otherwise, if you specify that you are only interested in the main title it

can do that as well).

  • The verdict
    : this is simply a great program that finally brings another free alternative for doing this sort of task aside from DVD Shrink. What I like about it is that it is simple, straightforward, and narrows down the decisions that a user has to contend with to the bare minimum. It’s also probably the fastest freeware program that does what it does.The User interface:
    is simple and straightforward, with only a limited number of decisions that the user is asked to make (see below).
  • Performance: in my test, Amok DVD Shrinker successfully compressed a 6+ gig DVD into 4.7 gigs in 20 minutes (with the quality/speed slider pushed past the mid-point to favor quality over speed, and the preview window enabled). The Amok site states that Amok DVD Shrinker is faster than the well known DVD Shrink, and although I did not scientifically compare these two under the same conditions I remember that DVD Shrink, hitherto the freeware standard bearer for this kind of task, typically took hours to process anything, not minutes.
  • User input: the user is only required to make 4 decisions, as follows; (1) the desired output size (e.g. 4.7 gigs for a normal DVD), (2) whether you want the only main movie or the whole DVD with menus and features, (3) whether you want all the different language tracks included or select a singe audio track from the dropdown, and (4) the user’s preference for speed of processing vs. performance on a 5 point scale.
  • Encryption: please note that this program is not designed to remove encryption from commercial DVDs, but rather processes the DVD data once it has been decrypted. If you need a freeware DVD decryption program try RipIt4Me/DVD Decrypter, DVD FAB HD Decrypter, or DVD43 (which decrypts in real time without needing to save to the hard disk first).
  • Creates ISO: at the end of the shrinking process. If you need a free program that can burn your ISO file to DVD use IMGburn.
  • Portable: two versions available, a setup version that installs normally and a zipped version that you can unpack and use without installing.
  • The preview window: gives you a glimpse of what the program is processing at that particular moment (the aspect ratio in the preview is incorrect but don’t worry the DVD is processing correctly). Switch this off for faster processing.

    Since DVD Shrink started having trouble with newer DVDs, I’ve been using DVDFab’s free HD DVD Decrypter

    and then DVD Shrink, which sounds like the same process that this requires. DVD Shrink seems to work much faster on a decrypted folder than it ever did on an encrypted DVD (though it never took hours for me). I think 20 minutes is about the average now.

    Still, it’s nice to know that there’s an alternative that’s actively being developed AND is portable.

  • Nice one, Samer!

    Does this just shrink the files to DVD format only or does it rip it to an AVI format of 700 megs if I want?

    A couple more notes in comparison to DVD Shrink:

    I just tried it, and it wasn’t faster than DVD Shrink on a DVD I shrank last night – it took 43 minutes with the slider at the middle (default) setting.

    The simplicity is great, but I prefer DVD Shrink’s options to eliminate audio and subtitles or reduce the menu and extra quality in order to maximize the quality of the main movie without re-authoring the disk.


    This just shrinks to an ISO, with a minimum size setting at 2.5 GB. You’ll have to use something like HandBrake to transcode into your AVI.

  • I have been using DVD shrink for a few years and sometimes find the quality poor.
    Does anyone know how Amok DVD compares?

  • Neat! I’ve never heard of this tool. It looks promising. Thank you.

    DVD Shrink and this thing are requantizing the MPEG2 stream. MPEG video compression works by periodically using full frames then calculating those in-between base on differences from the surrounding frames. These apps reduce the amount of information that represents the “differences.” The same process is used with a lot of digital television. DVD Shrink (which begeat Nero’s shrinker) has a high-quality mode which does 2-passes. The first pass analyzes the complexity of the image so more busy parts of the video will have more data. Amok DVD doesn’t do that which means the result cannot be as good as a 2-pass DVD Shrink operation. If you like to strip contents with DVD Shrink, consider using PGCEdit and Vob Blanker to get rid of extra junk because they are more complete than the simple editing of DVD Shrink. The most popular app for automating DVD-9 to DVD-5 with actual re-encoding is DVD Rebuilder. There is a free version and a commercial version. Depending on the source material and the filtering used, it’s actually possible to get a higher quality DVD-5 from a DVD-9 original if the source is a low quality transfer.

  • I just tried it. The results were quite bad. For my first attempt, the quality seems at least as bad as DVD Shrink on single pass mode. 🙁 It did not seem to be any faster than DVD Shrink on single pass mode would be either.

    So far, the program is a dud for my purposes. I may try it again just to make sure it wasn’t a fluke.


  • Samer

    This is interesting feedback. I actually cannot imagine a bad result, simply because I peformed a test for this review and the results I got were excellent. The only thing I can add is try it on the highest quality level and see if that makes a difference.

  • I did try it on the highest quality setting. My DVD was only slightly over sized, so the software wouldn’t have to work very hard to reduce it. It still took about 30 mins.

    I was going to try one more DVD. The fact that you obviously loved the results gives me a 2nd reason to do so. But it’s starting to sound like several of us didn’t have as much luck as you. Maybe there is some quirk in the disks that is creating this behavior? It would be good if others could try it and let everyone know how it did for them.

    In my experience, DVD shrink is way better in comparison to this.

    Website seems kinda fishy; McAfee Sitadvisor marks it as yellow.

    “4 yellow downloads

    In our tests, we found downloads on this site that some people consider adware, spyware or other potentially unwanted programs.”

    However. Amok DVD Shrinker 1.2 is a green download.

  • very nice

  • Warning

    Found by Trend Micro… not adware or spyware but a TROJAN!!
    Be forwarned, it’s all on you.

  • Warning

    However. Amok DVD Shrinker 1.2 is a green download.

    THIS IS A CROCK !! IT contains a Trojan Virus! Ue at your own risk!
    It’s NOT adware either… it’s a TROJAN!

  • Samer

    I doubt very much that Amok DVD Shrinker is malicious. The programmer behind the Amok prodcuts – Dirk Paehl – is well known and has contributed a lot to the freeware scene. In my mind it is much more probable that what you have on your hands is a false positive than the program being malicious. Especially when I tried and reviewed the product and it caused no adverse reaction from my battery of security programs or any adverse effect on my system.

    I have had multiple scares with false positives reported on a number of programs that I reviewed, and after investigation none was proven to be the case. I believe this is another such case, but will investigate further and write more about this.

    Firstly, it’s not malware.

    Secondly, it seems to be faster than DVDShrink – at least with my computer. I’m used to 45-60 minutes with DVDShrink, but Amok did Pearl Harbor in 30 minutes. It’s really no big deal, since I usually shrink DVDs in the background, while doing something else… what’s 15 minutes in a hobby? But still, of course, fast is nice.

    The quality was quite good. I’m a photographer, and a highly visual person, so I count what I see. The audio part must be judged by someone else.

    If you start to use it, it really needs an additional .dll in order to encrypt movies. Since it seems to be somewhat illegal (?), I won’t name it here, so as not to put Samer in any trouble.

    In my view, it’s a good Shrinker, and it’s quite safe. The outcome is of good quality, and thus, I can recommend it.

  • i have downloaded a movie from the net and be fucked if i can get dvd shrink to recognise it
