Disk Image Video Pixelates when panning

I just completed my first dvd project and exported it to a disk image to test it out.
When I played back the video in the DVD player the video became pixelated whenever the camera panned left or right in the image. This did not seem to happen when I played the video in Quicktime. The video files were all .avi files.
Is there a way to overcome this? Would converting the .avi files to something else help at all?

Hmm, it actually looks like it is a weird FPS.
23.98
23.98?? There is a movie standard 24 fps.... If that's really the frame rate, QuickTime has to insert 6 duplicate frames per second to get to the NTSC standard 29.97 fps. That could make things a little jerky.
Format: 704 x 384, Thousands
ATSC A/52 and AC-3 Decoder, Stereo, 48.000 kHz
The file is only 8-bit color (Thousands) and not 24-bit color (Millions) - that could make some areas blocky.
Making S L O W pans is the best way to avoid pixelated pans on a DVD.

Unable to burn AUDIO to DVD or Disk image, video is fine

As many other posts have stated; I am unable to burn the Audio portion of an iDVD nor does "save as disk image" transfer the audio of my iDVD. Transferred an iMovie, (an iPhoto set of photos with iTunes audio imported into iMovie) to iDVD. Audio plays on iMovie, audio plays on iDVD preview. Tried removing recommended ~com.apple.iXXX.plist, no help. Tried different encoding methods: i.e. Best/High/Professional. Tried saving to different sizes HD/Large/etc. Tried Share Media in iTunes, Media Browser, etc. Checked Main Audio, volume slider bar in iDVD. Tried importing audio into iDVD rather than transferring from iMovie. It doesn't seem to matter how I build the iDVD it works, until I go to Save As Disk Image or Burn DVD. Video works great (better in Large than HD) Audio doesn't transfer.
21 total minutes, 1.15GB of final iDVD using a default theme.

Hi
(an iPhoto set of photos with iTunes audio imported into iMovie) to iDVD
Yes this is the problem - in iTunes there is a copy-protection that moves over
Result
• Plays well in iMovie
• Plays well in iDVD preview
• Silent on DVD
Only way around this is to in iTunes collect needed audio into a play-list
Burn this out as an Audio-CD and .aiff (NOT .mp3)
Use the audio on this CD in Your iMovie project.

Disk image files error when dragging files from them

any disk image file .DMG that i download and it either has a file to drag to the hard drive or has an application in it. They mount fine and i can lookinside them but when i drag a file out it seems to partially copy them but then comes up and says..
Sorry the operation could not be completed because an unexpected error occured (Error code -41).
If the dmg file has an installer it starts the installed and asks the normal question and permissions and then where to install to then try's to start but just errors again.
Anyone got any ideas. This is on a Mac intel Mini. Everything runs fine and as i said i fixted permissions it is an administrator account.
I have tried 3 disk images firefox opera and ablelive 5.2 they are not damaged or corrupted
thanks

I was having the same problem on my G4 Powerbook when I tried to install Adium and TextWrangler from disk images. After trying several things that didn't work I decided to see if my IP filter was the culprit. I opened PeerGuardian and disabled the filters. Then, I downloaded Adium again, and it copied easily from the disk image to my applications folder. Then, I tested TextWrangler and it worked as well. I don't know why that worked, and it might not be your problem, but I thought I'd pass on the info. Hope it helps.

Creating an Encrypted Disk Image on an External (USB) Drive

I have an external 600 GB drive (2x 300 GB SATA 3.5" disks in a Thecus N2050 RAID0 external enclosure connected to iMac by USB2) onto which I would like to backup a large amount of data (500 GB).
I store this external drive away from my home (in the office) and since I cannot guarantee physically locking away the drive I would like to logically lock the drive by placing all the backup data into an encrypted disk image created on that volume.
I have tried creating an encrypted disk image on my USB volume in Disk Utility (Apple's instructions here) but I experience a number of issues not documented in the Apple article:
1) I am not presented with a drop-down option for the size of the disk image.
2) When I go ahead and try to creat the image I am told that the creation was impossible "file or folder does not exist".
Is it possible to create disk images on USB volumes (I cannot create such a large disk image on my iMac HDD as I do not have sufficient space).
thanks in advance
Raf

I realised that in Disk Utility you must not have any of your mounted drives highlighted in the left hand pane.

How do I encrypt my external hard drive and subsequently a specific file within it, using my Mac? I tried creating a disk image but permission was denied.

Encrypting an external hard drive and specific folders within. Permission denied using disk image.

When I tried to encrypt a single file within the hard drive itself, I got the following: Disk Utility Progress: Unable to create "Name of my file" (Permission Denied).
When I tried encrypting the entire hard disk itself, I got: A GUID Partition Table (GPT) partitioning scheme is required.
I have also currently used Time Machine on the external hard drive, along with saving other data. Hence, I am not sure if partitioning is going to delete any of this (a video I watched mentioned that using the + button when creating partitions retains current data). Backing up the external hard drive is out of the option since it is the back up to my Mac.
You can't encrypt a single file. I'm not sure what you did to try. You can make an encrypted disk image which begins with a folder, if desired. Or, you can just create a blank, encrypted disk image, then move your desired files into that.
While you could partition off the free space without erasing the disk, you cannot encrypt it because you need a GUID Partition table which requires you to repartition the entire drive, not just the free space.

Password-protected Sparse Disk Image Bundle remembered after eject

I use password-protected Sparse Disk Image Bundles to protect some files. Every now and then, when I open the image, it doesn't ask me for the password and opens immediately.
At first, I thought I may have inadvertantly agreed to save the password in Keychains. But that is not the case. After running some tests, I noticed it may take up to 3 ejects before it asks me for the password again. It seems to happen more when I modify files in the disk image, but not when I simply read files. I suspect it is not completely unmounting the image.
This is potentially a security issue. Any suggestion on what I can do short of re-ejecting images until it asks for a password again?

You may have successfully increased the sparsebundle's potential capacity while failing to resize the contained partition. That seems to be what happened when I tried this myself. A resized sparsebundle containing the same files would not occupy much more space on disk than it did before.
*Provided you have a backup*, you could try the following:
Remount the image, then run Disk Utility and select the .sparsebundle (non-indented icon) in the left pane. Click on the Partition tab, and then see if you can pull down the lower right corner of the disk image partition to increase its size. If you can, then drag it to the bottom and click Apply.
Again don't try this without a backup. It may not be worth doing in any event - it's easy enough just to make a new, bigger sparsebundle and copy your stuff over.

Managing Events and/or Projects With Disk Images

I came across this method of managing Events and Projects a while ago. I finally got around to giving it a try. Personally, I really like this method.
It's simple.
It keeps things very well organized.
It's easy to open only the project or events that you want.
It's easy to consolidate and back up once you're done.
It takes some workload off FCP X by not having to always open up all your Events and Projects.
So, I thought I would share this for those of you who were not already aware of it.
This is my workflow: (based on the link below)
I create a Disk Image (named for the Event/Project).
(Note: There are two places to create the name, I use both, keep them the same)
I open up FCP X.
I typically put only one Event on this Disk Image.
I then reference whatever Media I need in this Event.
I usually don't bother to copy the media. (except when I'm done and I archive it)
You can create multiple Events, if you feel the need for additional organization.
Then I create however many Projects I need.
(since Projects equates to Sequences from prior FCP versions)
I have a unique Disk Image for each Event/Project that I work on.
To use them ...
First, always make sure FCP X is not running.
Locate the Disk Image in finder.
Double click on the Disk Image and it will Mount on your desktop.
(assuming it's not already mounted on your desktop)
Open up FCP X and it will load the Event(s)/Project(s) in the Disk Image.
If you don't want to work on an Event/Project in FCP X (make sure FCP X is not open), in Finder, simply Eject the Disk Image.
Now when you open FCP X, it won't be there.
Its not gone, but since it's not mounted on the desktop, FCP X simply doesn't see it.
To get it back (obviously quit FCP X first) simply double click the Disk Image in Finder and it remounts.
Open FCP X and you can see it's back.
You can open (double click to mount) as many Event/Project Disk Images as you want.
Just make sure you mount and un-mount disk images when FCP X is not running.
If find this to be a great workflow.
Many thanks to Steve Martin of Riple Training for posting this method.

Re the final commercial spot. What I am getting at is if all my media is optimized and therefore in ProRes, and I export in ProRes using the current settings, then shouldn't the media needed to rebuild the project be the same or close to what an exported Quicktime would have been?
Perhaps the notion of "used clips only" is not what it says then. I took that to be the "media managed" feature otherwise why is that wording there. I guess "used" actually refers to all of the media for the project and associated events rather than just for the project. This is misleading because the DUPLICATE operation and menu prompt only appears as a result of requesting an action on the project item.
There are aliases in my original event folder, but before I started this process tried to get FCPX to consolidate media for the project and it already was according the app. Truth is, some of the media is outside of the FCPX required folders. So it's strange that it says it's consolditated, but it's not and yet in duplicating the project it moves the references to the new volume only to point back to the old volume.
So my next question would be: Is there no feature to back up only what's needed to rebuild the final project (edit) reliably. Moving the project moves everything. According to the FCP manual, it seems using the Duplicate feature is the way I should be archiving. However if by "used clips only" FCP X means all media and refrerenced events, then I guess there's nothing for me in here. However then, whey would there be an option (after choosing duplicate project) an option to Duplicate Project and referenced events. If "used clips only" means all media, then there's no difference between the 2nd and 3rd Duplicate Project options.
Thanks Tom.

Disk Image (.dmg) files no longer mount

Since updating to 10.4.9, I cannot mount disk image files. When I double click on them, I get an error dialog from Finder which reads, 'The Following disk images failed to mount.' Reason: 'Device not configured.' I suspect that some essential software, 'Disk Copy' and/or 'Diskimagemounter' did not, for one reason or another install with the rest of the update. My computer did crash when the update was almost complete, but after a restart, everything seemed to work OK, except for not being able to mount disk images, which in this age of downloadable software basically makes your Mac dead in the water. Any solutions, suggestions would be greatly appreciated. Thanks all!

Your Mac crashed before the update installation process was complete and before the prompt to restart?
If so - Houston, we have a problem. ;~)
Did you check your boot volume for any directory problems with Disk First Aid repair via Disk Utility when booted from your Tiger install disc immediately before the install and did you quit all running applications before the install?
Regardless and as a first step, check this link for system troubleshooting procedures and when doing so, follow all steps/instructions in the order provided.
http://www.thexlab.com/faqs/repairprocess.html
Test if this resolves the mount disk images problem since you should download the 10.4.9 Combo Update and re-install 10.4.9 since your Mac crashed before the install was 100% complete.

How do you create a disk image using Disk Copy?

Hello,
Is there any way you can create a disk image using Disc Copy? Is there a better way to create a Disk Image?
I would like to burn two copies of a 4.2 gig folder on my mac. I usually insert a blank DVD-R and then the mac asks if I would like to prepare it at which point I click "yes". An icon of a DVD disk appears on the desktop and then I drag my files onto this icon. It takes a few moments to create the disc image and then I click "burn". However, after the disc is burned the disc image disappears and I have to start all over again if I want to make another copy.
How can I save this disc image? If I could save the disc image, it would enable me to burn a second DVD right after the first without having to create the disk image all over again. This would save a lot if time.
I am using OS 10.1.5
Thank you for any suggestions

Thanks Niel for the info about creating a Disk Image with the Disk Copy utility in OS 10.1.5
That worked however when I insert a blank DVD-R, the disk image still has to be copied to the DVD-R buffer and then it can be burned. And so this doesn't really save any steps - the "copying into the buffer" step still has to occur whether or not you have created a disk image of your files. So creating a disk image doesn't really shorten the process of burning multiple copies of a DVD.
I will try to describe the steps more clearly:
Two of the three steps for creating a DVD (steps 2 and 3) are very time-consuming:
1. put blank DVD into the drive (a DVD disk icon quickly appears)
2. drag files onto this icon (this step takes a long time as the files are copied into the buffer)
3. choose "burn" (the actual burning also takes a long time)
I was hoping that when I create two or more DVDs of the same files, I could first create a Disk image so that when I create the second DVD, step 2 could be skipped. That does not seem to be the case - the disk image still has to be re-loaded. And so I think I will not bother with the Disk image idea - it doesn't seem to be necessary or helpful when burning DVDs to backup data.
Thanks for your suggestion.

OS X Encrypted Disk Image Tool Buggy?

Hi,
I'm trying to create an encrypted file directory on an external HDD (My Book). I decided to try the OS X software to create one. I have tried both the following options, each of which has been buggy when transferring files into the created images:
* 50GB Encrypted "Sparse Disk Image"
* 50GB Encrypted "Read/Write Disk Image"
CASE 1 - "Sparse Disk Image" - errors occur when loading data/files into these images. When I check them via Verify the Disk Utility says there is a "Invalid B-tree node size" and the repair does not work.
Questions:
[1] Is this a known Apple OSX bug?
[2] Is there a way to lodge a bug request with apple?
[3] Is there a well known/popular folder/file encryption Mac software package that works that someone could recommend?
Details from the logs:
Jul 1 16:48:43: Disk Utility started.
Verifying volume “raw_data”
Checking HFS Plus volume.

Is the external drive a USB drive formatted as FAT32? If it's USB and you're using it "out of the box" without having reformatted it, then it's probably FAT32.
FAT32 filesystems can't properly hold a file larger than 2GB. I ran into this with a pocket size 12GB USB drive. Once the sparseimage file gets close to 2GB, things go haywire.
If you don't need to share the drive with Windows machines, reformat the drive as Journaled HFS+, and the problem should go away. Otherwise, keep the sparseimage files well under 2GB.

Scanned images lost via disk image

Scanned over 400 slides using Canon 8600 with PhotoStudio and saved as JPGs. To transfer to a PC I selected to save as an MS-Dos format and understood I had to create a Disk Image. Did all that, now I can't find any trace of the JPGs I saved, and no Disk Images are noted when I searched the hard drive. Any ideas how to locate my pictures?

Have found my .dmg files I scanned in. They are in KeyChain App and have been unlocked, but I can't find a way to get the JPG images out of the disk image. Any help would be greatly appreciated.

TC Backup Volume Structure - Folder Based or Disk Image?

Hi,
Is the backup volume in TC folder based (which is used on drives connected via USB or FW) or Disk Image-based (used when you 'force-enable' the wireless backup support for TM)? I'm quite curious 'coz what I noticed with the Disk Image-based backup volume is that it crashes the TM's 'disk handling' software when the image bloats to about 14Gb in size. If the TC's backup volume uses disk image as well, then there could be a possibility that the software will crash when mounting huge dmgs.
thanks,
zurc

yikes! pls do let us know what happens if the sparse image goes to about 14GB... my Airport Extreme's disk-handling software crashes when I try to mount a volume with that size... which actually is the size of TM's 'unofficially' supported backup sparseimage.
thanks!

How can I save an idvd disk image to secondary hard drive?

I'm trying to tshoot a burning issue with my 1st imovie/idvd project (some old home movies). I've found the hints to try the 'save disk image' option, but when I choose that option I get a 'multiplexer preparation error; not enough free space'. I know my primary drive doesn't have enough room but my secondary one does. Problem is idvd seems to default to the primary and I haven't found an option to choose to save to the secondary. Probably something simple, but I'm not finding it. Can someone point me in the right direction?

Probably something simple, but I'm not finding it. Can someone point me in the right direction?
You need to move enough 'things' from your start-up hard drive to your external hard drive to free up 10 to 20 GB if you want iDVD to work. Your start-up drive is where everything happens and you can't change that.

Time Machine Backups of Encrypted Disk Images, Part 2

Hi:
If Time Machine is backing up a hard drive that contains a subset encrypted disk image as part of its contents, and this encrypted disk image is mounted (in an unencrypted state) where the enclosed data has been changed/manipulated in any fashion, what and when does Time Machine backup?
In other words, does the data in the encrypted disk image only change when the encrypted disk image is unmounted? Or is it somehow backed up real time even when the encrypted disk image is mounted on the desktop in an unencrypted state while Time Machine is working?
Sorry I can't explain this very well, but hopefully the gist is clear.
Thanks!
(OS 10.8.2)

Time Machine doesn't back up a disk image file while it's mounted, whether encrypted or not.

Help with backing up files and opening from disk image.

I am trying to back up my hard drive so that I can send my PowerBook in for repair. I used disk utility from my Panther install discs to create a disk image of my HD.
The disk image was created successfully and mounts perfectly on my HD. I can open it and open all of my files from the disk image just fine when it is mounted on my PowerBook.
However, when I take it to a different Mac, things start getting sketchy. I can open Word files just fine, but Excel files claim they are read-only and cannot open. I checked the permission back on my PowerBook to see what was up, and the files were read/write for the owner and read-only for groups and others, but they should still open as read-only files right? I even checked the permissions on the Word files to see if there was a difference, but there was no difference.
I can take the external HD back to my PowerBook, remount it, and open everything fine, but then on the other Mac it is a no go.
I need to back this up for when it is out on repair, but I need to know that the files will open in case I need to restore my disk.
Can anyone help??
BTW, I couldn't find the best forum to post this in, if there is a better one please direct me there...

solution:
I went into the Apple Store nearby today to send my PowerBook off for repair for a screen issue, and in the process got help with my backing up issue.
It seems all one needs to do is copy the file from the external hard drive to the internal drive.
It was that simple.
