Is it possible to compress a disk image to fit on a single layer DVDR

I have created a disk image from one of my iDVD projects and its about 5.7Gb. I was wondering if there is a free program out there to compress the disk image so I can fit it on a single layer DVD-/+R? Thanks in advance for the help!

I don't know much about free software but Roxio Toast has a Fit to DVD option I often use for this same purpose that works rather well.
Also, after searching google, I did find this one link which may help you. I've never used it myself so I'm not completely sure of how well it will work but it may help you.

  • How do I compress a disk image (or DVD)

    I have a DVD that's 7.6GB and I want to compress it and save it on my hard drive. It's a concert DVD (copyright protected I'm sure) so I want fairly simple access to it after compression. I made a disk image of the DVD and then saved the disc image to the desktop using Disc Utility. A disc image file that ends with ".CDR" is created and saved on the desktop. I have no problem opening the resulting file (.CDR disc image) and getting it to play in the DVD player or anything like that, however it's still a 7.6 GB file. Is there a way to compress the disc image? I read a post about dragging/dropping the disc image from the desktop into terminal (which I've never even opened before today) and then terminal would automatically compress the disc image. Is this correct? If it is, where is the resulting file (the compressed disc image) then stored? Is this even the easiest way to compress a DVD? Do I even need to make a disc image first, or is there software that will automatically compress the DVD for me and allow my DVD player to open it? It seems like there ought to be an easier way. What am I missing here? I'm not going to save a DVD (or disc image for that matter) that takes up that much space (7.6GB) on my hard drive. Thanks for any help. Michael

    Copy protected DVD's (if that is what this one is) make copying difficult by intent. You can try MactheRipper to "rip" it to unprotected form, but please read & heed the caution about the legality of doing so at the developer's web site.
    This app may or may not remove any copy protection, since DVD makers understandably sometimes modify their schemes in an attempt to defeat apps like this one. You may also need to make decisions during the ripping process that may affect the way the content plays. IOW, this isn't a 'one-button & your done' sort of thing.
    That said, any unprotected DVD can be compressed in various ways by various apps, but you should be aware that compression affects playback quality. Different apps give you greater or lesser control over this & it may well be that compressing the content to a size acceptable to you results in quality that isn't acceptable.
    The commercial apps Popcorn & Toast Titanium 7 are probably the easiest to use for this, but that is because they mainly are intended to compress 'jumbo' DVD's down to a size that fits onto regular ones, about 4.7 GB. For better control of compression vs. quality, you will probably have to use more 'geeky' stuff and/or use MactheRipper to discard whatever is least important to you.
    If all this sounds like too much trouble, consider investing in more drive space for your .cdr files or just buying extra copies of the DVD's you need to archive.

  • Importing Akai disk image file

    I've just switched from Cubase SX4 to Logic Pro 8. Unfortunately I'm unable to use my library of Akai disk image files stored on my hard drives. Isn't EXS24 able to load from image files, like Halion does?
    I went through the whole process of storing the CDs on my hard drive, because Halion lets you load directly from image files, making this method far better than using the actual CDs...
    Help would be appreciated.

    Go into Project/Project Info... and see if single-layer is selected in the pop-up. If it is, it should create a disk image to fit on a single-layer DVD-R.
    I recommend a disk image burned to Verbatim DVD-R at 4X or slower using Toast or Disk Utility. You can set burn speed in iDVD '08 if not creating a disc image.
    David Pogue also recommends Verbatim on page 356 of his iDVD 6 book:
    iMovie HD & iDVD 6: The Missing Manual
    Quoting David: "Cheaper brands don't use the same amount of organic dyes and are more likely to suffer premature deaths."
    I buy Verbatim white inkjet printable in stacks of 50. Verbatim's part number: 94971. They have been flawless for me.
    *Burning speed*: Go into the menu > iDVD/Preferences/Advanced. Look at the bottom of that window.

  • Is it possible to recover iCal calendars from disk image of hard drive?

    Hi, I made and saved a disk image of intel imac hard-drive with a g4 imac running leo. I now want to recover the info contained on iCal in my account on that disk image. Is it possible without restoring that disk image on to an intel imac?
    I wanted a clean install on the new imac for reasons that are valid, and some that I'm not quite sure were valid reasons such as security, since I don't know what is on the net that can or cannot compromise security either through website visits or email.

    Yes it is, and with the links provided below in the "More Like This" you'll be able to get the right info.

  • Disk Utility, disk image help

    I want to burn a disk image onto a disc using disk utility, however i dont know how to and my blank disk is smaller than the disk image size. SO i need to compress it. Can anyone tell me what to do and how i can burn a disc image onto a disc which is too small?

    Not all disk images are compressed, but you can't make a compressed disc (not with standard software).  You can store a compressed disk image on a disc, but it won't behave like a normal disc (e.g., you'd need to mount the disc, then mount the disk image stored on it separately).  If you want to create a normal, mountable disc, you either need to get a physical disc of the appropriate size and burn the uncompressed image onto it (Disk Utility has a Burn item in one of its menus), or you'll need to reduce the size of the uncompressed disk image to fit the size of the disc you have.

  • Burning several disk images in one DVD

    Is it possible to bun 2 disk images on a DVD? I tried in DU but if both .img are selected,"Burn" is greyed.
    Alternatively, how can I combine 2 disk images into one, so that DU will accept to burn it?
    I found the following advice a Forum:
    A .dmg file is a disk image, and can be treated like any other disk. You can copy the contents of one into another, or make a new blank image and copy their contents into that.
    I did that, but, as I said, DU doesn't agree
    Those disk images contain home videos which have been edited in iMovie 5, but cannot be burned in iDVD because my Mac mini has no DVD burner. So I create a disk image in iDVD and use DU -> Images -> burn on an external burner.
    Also, is it possible to rename a DVD? For some reason the latest DVD is bearing the same name as the DVD burned just before it.

    your whole topic is Finder-related, MacOs allows/supports simple drag'n drop...
    your both .imgs exist at some location of your Mac, right?
    no app needed nor running...
    insert an empty dvd-r
    your Mac will ask you what to do...
    you do: drag'n drop both .img files onto disk...
    hit the burn button in disk's window..
    no step 3), boom! done..

  • IDVD create disk image larger than DVD-R capacity

    Here's the background:
    - I made an iMovie 6 in 16:9 NTSC that is 1:32:00:06 long. I put that into iDVD 6, use the 5.0 Theme called "Wedding White", no slideshow, just a few photos and one 128k audio AAC file for menu music. Motion menu right now is about 5min45sec, but I can change that no problem.
    - In iDVD 6's "Project info", left hand column shows "NTSC", "Widescreen (16:9)", "Best Quality", "Single-Layer (SL) - 4.2GB"; all correct.
    Right hand column - Project Duration is 97:47min, Motion Menus is 5:46 of 7:30, Tracks 1 of 99, Menus 3 of 99; all green.
    "DVD Capacity" was shown as ~3.3GB before the burning.
    Here's the problem:
    - When I first burned directly onto a single-layer DVD-R, an error will come on during burning or multiplexing near the end. Disc will eject, and the disc IS PLAYABLE on all DVD players. Only problem is that the movie will end (or says "Disc scratched or dirty", then crashes DVD Player on my Mac) at around 1:30:50; about 1min 11sec short. iDVD will also hang, and need to be forced quit.
    - If I check that finished DVD-R with Disk Utility, it'll show:
    --Capacity 4.4GB (4,706,074,624)
    --Used 4.4GB (4,739,385,344)
    - Same results with two decent media, a Sony 16x and a Ritex G05 8x.
    - After reading a lot of posts in this discussion board, I tried two things:
    1. Clean up my primary HD, which was down to <10GB free. I realized that I need double the disk space to properly burn. Now, it's at around 30GB free.
    2. Instead of direct burn, I saved it as Disc Image. Results:
    -- Video_TS file totally fine when played with DVD Player.
    -- Disc Utility shows: Capacity 4,739,923,968 Bytes, Used 4,739,385,344 Bytes
    But when I tried to burn that image onto a disc in Disk Utility, it says the media doesn't have enough room.
    3. I went back to iDVD 6's "Project Info", and the "DVD Capacity" bar is now filled, yellow and says "4.2GB of 4.2GB".
    [I actually tried earlier with a slightly different version with longer motion menus, and a slightly longer movie. And the DVD it tried to burn is even larger, at 4,847,159,296 Bytes. Similar results, but that DVD will end about 4 minutes short. But I didn't write down all the iDVD 6 details that time.]
    SOOOOOO....
    It seems to me that iDVD 6 is miscalculating its rendering or compression ratio, and is creating a final disc image larger than the capacity of a single-layer DVD-R, even though all parameters are set and displayed correctly.
    For me, I'll cut down on the motion menu duration to see if that will help, as I'm right now JUST BARELY over the capacity.
    Because of the early audio problem with iMovie/iDVD 6, this is the my first "finished" iDVD 6 product. Before, I have had no problem with movies that are close to the 120-minute limit, though this is the first time I use a 5.0 Theme with motion menus.
    So, any ideas, any comments? Please post. Also, what else should I do besides posting here to let Apple and other users know of this problem? Thanks!

    An update:
    I cut down the loop duration of the motion menus, from 5:46 to 2:50. The resulting disc image is down to 4.25GB (4,563,716,096 bytes) and will fit onto a single-layer DVD-R.
    So, I finally made my first successful DVD using iDVD 6. Still don't know why this has been such an adventure compared to earlier iLife versions.

  • Trying to burn a disk image

    I created a disk image .iso using DeVeDe on a linux machine. Now I'm trying to burn that image to a dvd on my Mac computer using "Disk Utility".
    The .iso is 4.4GB, using a DVD-R that holds 4.7GB. It's saying the DVD isn't large enough to burn the file.
    According to my calculations, there are 0.3GB more space than I need on the DVD!
    Why is it saying the DVD doesn't have enough space to burn the file?

    You are ignoring "head room" that DVDs need for titles, indexing, etc. The finalizing process also adds to the space. If you don't leave 5% or so you are looking at burning a coaster.
    However, there are some burners, such as Toast, that can compress the file sufficiently to fit on a single DVD. I have written 6 GB movie files to a single DVD. Naturally the quality suffers but if it's an old movie or one DLs from the net, it's moot.
    This only applies to movies etc., never to a data DVD which has to be copied perfectly, bit for bit.

  • Disk images and storage space.

    Dear members:
    After a disk image is created and saved, how much storage space does one need to work with it ?
    Let's say I create a 10 GB disk image that is saved in an encrypted form. Once I try to open it I have first to provide a password and then the drive corresponding to this image mounts to the desktop. Once the drive is mounted, since I have the disk image and the drive, does it mean that I actually have 20 GB added to my desktop folder or both files combined still take up only 10 GB of storage space ?
    One other question:
    I have saved a disk image to an external Firewire hard disk. When I click on this disk image the drive mounts on the desktop. Is there a way to open this disk image so that the drive is actually mounted on the same external disk where the image is or does it always mount on the desktop independent of where the image is ?
    Thank you in advance for your help.
    Best regards,
    Joseph Chamberlain

    Hi, Joseph.
    1. You wrote: "In case I wanted to would it be possible to create a disk image on another drive and also mount the disk from this image on that same drive ? For instance, can I create a disk image on an external Firewire drive and then mount the disk from this image on this same external disk ?"I'm not quite sure what you're saying here. I thought I addressed this.
    You can create a disk image and save it on an external drive. Double-clicking that disk image (saved on an external drive) will mount it, with the mount point being in /Volumes, same as every other mounted volume on your computer, as discussed in my prior post.
    2. You wrote: "On another discussion I initiated one poster said that when creating a bootable external drive it is important to uncheck the square for "Ignore Ownership". I just installed OS X 10.4 on a LaCie 120 GB external Firewire drive and after the installation process noticed that the "Get Info" panel shows the box "Ignore Ownership" checked. Is there a problem ?"You do not want "Ignore Ownership" checked on a bootable volume, i.e. a volume on which you installed Mac OS X. That installation may not work properly.
    3. You wrote: "In case there is, shouldn't OS X have unchecked this option as it installed itself on this particular drive ?"I don't know. I've never tried installing Mac OS X on an external volume that had "Ignore Ownership" checked before installation.
    4. You wrote: "What does the option "Ignore Ownership" mean and why/when should I use it ?"See "Mac OS X 10.4 Help: I don't have permission to use a disk. The only time I would use this feature is if I had a volume on an external drive, e.g. FireWire drive, that needed to be accessed and written-to by multiple users of the computer to which that external drive was connected. The volume in question should contain only data — not a bootable volume, i.e. one with Mac OS X installed — and one should also be prepared that anyone could add, delete, or modify files on that volume since permissions are ignored when "Ignore Ownership" is enabled.
    FYI: When asking multiple questions, numbering them individually is helpful. Then someone can respond by number to link the answer to the question, vs. quoting the text as above.

  • Using Encrypted Disk Images

    When I create an encrypted sparse bundle disk image it starts small an grows when I add files. When I create a sparse disk image it starts at the size I set and never grows. I understand all this however, what I don't understand is gaining FREE space again. When I delete a file I don't get back the free space on the mounted virtual drive but the disk image is still the same size! I know that filevault (which basically just places your home folder in an encrypted Sparse bundle image) some how recovers space, is this possible with other ENCRYPTED disk images as well?
    Thanks in advance,
    Macguy3000

    A sparse image file can expand but it does not automatically contract as data is removed. I believe I remember reading a hint at MacOSXHints.com about how to resize a sparse image file.

  • Creating disk image & time machine question

    I have really screwed the pooch here. I run Adobe photoshop CS2 and Acrobat Pro 7.0 on my mac. I lost the install disks in a move last year, BUT I had created a backup disk image for both and had them saved in a folder on my backup drive. Last week, when I had to take my mac in for hardware issues, I needed to do a backup of my data files and didn't have enough space on my backup drive, so I accidentally deleted that folder with all my install files. I have my licensing info for both programs - so that's not the issue - the issue is trying to figure out how I can locate either replacement disks or .dmg install files for the programs. I've searched the Internet, posted in Adobe forums but no luck. I called Adobe and they told me they don't offer disks or files for previous versions and asked me if I wanted to upgrade.
    So I have 2 questions:
    1. If anyone knows where I can get my hands on disks or disk image files for installing these two programs
    2. Is it possible to create a disk image of an install (.app) file? I know how to create a disk image of an install disk, I've done it before. But I was wondering if there's a way to make one of an install file.
    I know that I have time machine and have backed up my HD and apps. But I am extra paranoid now that I don't have a backup of the install files...and god forbid if I had to do a reinstall and for some reason my time machine backup fails me. Any help is appreciated. Thanks Jen

    Check through the TM backup and see if you've those images. You might get lucky, but since you moved those to the ext HD you might be up the proverbial creek without the paddle.
    1. Check ebay and buy replacement disks
    2. You can put anything into a disk image. Whether or not that'll allow you to use it to install something is another question.

  • RESTORE SYSTEM FROM DISK IMAGE

    Hi people,
    I was wandering if anyone could help me with this little thing. I hate Time Machine, so that's not a viable solution for my inquiry. What I want to do is migrate my whole SL system from my old MacBook to my new one. Is it possible to create a Disk Image of my old MacBook's Hard Drive with Disk Utility or any other software and then restore SL from it in my new one?
    *I know many of you may think TM is great, but I don't like it, so PLEASE spare me from lectures on why I should use it. I know I sound harsh, but every time I post something like this ten out of every eleven responses are about that.
    *PLEASE, I BEG you, don't inquire upon why I want to do it this way. Again, I sound mean, but most of the responses I get are usually a pile of uselessness that just takes up space and doesn't help.
    Thanks a lot for your time,
    ThePhazonMonkey

    Thomas is right. Restoring an older Mac's "whole SL system" (which I take to mean the entire contents of its startup disk) to a different one is a bad idea, whether you do it with a disk image, clone, or that app you hate so much.
    In the first place, there is no guarantee that the OS version on an older Mac will have all the files needed to support the newest ones, so all you may get for your efforts is a new Mac that won't boot at all or kernel panics soon afterwards.
    In the second, there is no guarantee that all the user & system settings from one Mac will be compatible with those of another. The OS will do its best to compensate for this, for instance by using defaults when the other Mac's settings are invalid or incompatible, but the process is not foolproof & you may experience instabilities or unexpected behavior that will be hard to track down & remedy.
    Do as Thomas suggests & use Migration Assistant, or better yet use Setup Assistant on the first startup of a new Mac to avoid any problems with duplicate user account names. (You cannot merge two existing user accounts with any automated software because each has its own set of home folder items that will conflict with the other's, so you must manually choose which ones to use with the account you want to keep.)

  • How to make iMovie 09 recognize a mounted disk image?

    I'm trying to store video clips in a disk image (Mac OS Extended - Journaled, single Apple Partition Map). Previously in iMovie 08 all I had to do was mount the image, start iMovie and it would recognize it as an additional drive. Then I could drag events to it and store them there. In 09 this does not work. It sees the image but has the yellow triangle/exclamation point in it. I cannot for the life of me figure out how to make it recognize the image! I've tried all variations in disk utility to create the image to no avail. Is iMovie 09 looking for a certain file on the disk image to recognize it? Maybe something in the DS_Store file or the .localized? Very frustrating.
    Hoping someone can help. Thanks.

    After typing the single space, drag the mounted disk image icon from the Desktop into the Terminal window, click inside the Terminal window, and then type <Return>.  Enter your admin password at the prompt (it will not echo on the screen),  and again type <Return>.
    Hopefully that will enable Spotlght indexing on the mounted image. It might take some time to complete depending on the contents.
    The result for this for me, three times, was "Indexing disabled."

  • HELP! Cannot Compress Footage to Single Layer DVD...

    Here's my problem.
    I cannot compress footage to single layer DVD. I'm trying to make a DVD with motion menus and a full length feature. TRT 1 hr 47 min 3 sec. I compressed the video and audio using compressor after it did not fit on one single layer DVD the first attempt. The file sizes of the newly compressed video and audio are adequate to fit on the 4.7GB DVD but after importing the into DVD Studio Pro 4 (DSP4) the disc size comes out to 5.1GB. After DSP4 does its own encoding the file sizes double. I cannot figure this out. Please help.
