Pixelation occurring after disc image burn

I'm having a problem with pixelation after performing a disc image burn through iDVD. I'm filming with Sony AX-2000 cameras onto Sony Memory Sticks, and loading the footage as Apple ProRes 422. The footage looks fine and no pixelation once loaded. After the edit is complete, I'm exporting it as a Quicktime self-contained movie, using "current settings" like I always have in the past. This QT self-contained movie file looks fine once complete, and there is no pixelation in it.
However, once I pull that file into iDVD, and then burn a disc image of it, I'm getting pixelation, but only in certain places. This is BEFORE I burn the actual DVD, but the pixelation does show up on the DVD. I'd say out of a 90 minute wedding video, there is a total of 5 minutes of pixelated footage spread out primarily over the first 30 minutes of the DVD. I've burned the disc image twice now, and it's pixelating in the same places.
I've been using this same process for the past 1 1/2 to 2 years without trouble on all my projects, but for some reason this wedding video is getting pixelation. I have no idea what to do and welcome any suggestions.

A couple of thoughts:
I assume you're evaluating the DVD on a television…because computer playback often gives misleading results.
If the artifacts continue to show up in TV playback, then try some tests using Compressor and/or DVD Studio Pro. Start with a small segment that includes the problem footage, and choose the 120 minutes Best Quality DVD preset. In Encoder, open quality and goose the bit rate up until the point where you're approaching the time limits of your video (the "allows" message provides time feedback at the bottom of the pane).In Frame Controls set Resize Filter to Best. In Preview, insert compression markers at the points where the artifacting begins. Either have Compressor spit out a test DVD as a job action or bring in into DVDSP to make a build without a menu. Evaluate.
Hopefully, you'll find the right recipe.

Alignment Issues with Buttons after disc is burned

I have a Widescreen project that I set in iDVD 6, and everything looks great on the preview. Once I burned it out to a disc and played it in another DVD player, the highlight marks for the buttons were distorted out to the left or right, depending on the original placement of the button. Is this a glitch they fixed in 6.02, or is there a button setting that controls this?

Welcome to iDVD Discussions.
Is this a glitch they fixed in 6.02,
You should always keep all software up-to-date!!! Including QuickTime.
Suggest you create a disc image and then burn the DVD. File/Save as Disc Image...
http://docs.info.apple.com/article.html?artnum=164927
This will isolate any encoding/burning issues you may encounter. Once the disc image is created, double-click the .img and burn the virtual disc that should appear on your desktop, using Toast to burn the DVD. Disk Utility to burn the .img file. Usually, you can select a burning speed in Disk Utility.
There are variations to this process based on which OS X you are using...
Open Disk Utility (in Utilities folder in Applications folder), click on the virtual disc (maybe the .img) in the left-hand window. Click the Burn icon. A new window should drop down and your SuperDrive tray will open after clicking the Burn icon. Insert a recordable DVD. (Verbatim DVD-R preferred by me.) Click the Close button. Wait. Select a burn speed. If you hold your mouse cursor over the pop-up it says: "Select a slower speed to work around burn failures," so select 4x or slower for best results. Then click the Burn button.
-->If the virtual disk selection won't allow you to click the Burn icon, use the .img file instead. This may have changed in 10.3.9 and did change in Tiger.
Also, you can use DVD Player to play the virtual disk to check your iDVD project before burning to DVD. Launch DVD Player. File/Open VIDEO_TS (Open DVD Media... in Player 4.6). Find the VIDEO_TS folder and open that. (The audio folder is for DVD-Audio disks.)

Error message when Saving as Disc Image & Burning

I've been getting this error message: Not enough free disk space for encoding the remaining assets.
When I'm either trying to Burn a DVD or Save as a Disc Image. I've read all of the previous discussions and nothing is working. I have 320 GB on my computer hard drive and 8GB of memory. I'm trying to burn a Large (960x540) movie that I created in iMovie that is 12 minutes long and 169 MB. There is no logical explanation that I can find for there to be any space issues in burning or saving this file.
Also, I found something that said to delete a preferences file, repair disk permissions and restart the computer. All of which I've also tried.
How can I get this to work?
Or is there any other way to get this photo slideshow w/music onto the DVD without loss of quality? It's not a long slideshow or a large file, so I'm baffled why the quality gets so bad when I try to burn it directly to a DVD. I followed steps I found in this community that said to publish the project to the Media Browser in the Large format and then import it into iDVD. Sounded like a good idea, but now I can't get it onto the DVD because of the error message (Not enough free disk space for encoding the remaining assets).
Thanks for any help!

Try this basic troubleshooting fix:
1 - delete the IDVD preference file, com.apple.iDVD.plist, that resides in your
User/Home/Library/ Preferences folder.
2 - delete IDVD'S cache file, Cache.db, that is located in your
User/Home/Library/Caches/com.apple.iDVD folder.
3 - launch IDVD and try again.
NOTE: In Lion and Mountain Lion the Home/Library folder is now invisible. To make it permanently visible enter the following in the Terminal application window: chflags nohidden ~/Library and hit the Enter button - 10.7: Un-hide the User Library folder.

Can't update project-menus become disabled after disc image save

I hope someone can help me understand if this is a bug or something I am doing wrong. I can never update a iDVD project with a new movie file, or change anything to the movie file (make it loop or stop looping). I have to create a new iDVD project anytime I want to make a change at all. If I change anything, once I save as disc image, the menu button becomes disabled and no longer works, even though the preview in the project window is fine.
I tried to change the file to a looping movie in the map view, saved the disc image, menu became disabled.
I am getting really frustrated because everytime I have to make a change I am starting all over creating a project from scratch yet again.
Is this a bug?
Thanks for input,
Cheryl

So here's the deal and I have done some surfing around these boards and have run across others that are encountering this same issue.
I have been able to, in the past, create a menu which plays a slideshow which looped (from iMovie or not). Suddenly, I can no longer create a looping slideshow AT ALL in iDVD.
I ran a test this morning where I deleted my .plist, restarted, then shared a .dv file from iMovieHD to iDVD6, created a simple menu with a "PLAY" button, saved as disc image, loaded up on my computer and it worked fine.
THEN, I did the whole sequence of events again as above, but this time, set the movie to "LOOP" in the map view - WHAM the menu "PLAY" button no longer works when I load it on my computer. The menu comes up, as it should, but the PLAY button doesn't start the movie.
I am now thinking this is a corruption in the software and I need to reinstall, why else would a feature suddenly STOP working???
Thanks for any advice.

Menu audio will play during preview but not when disc is burned.

Encore CS6.
Menu music plays fine in preview. I know that the file is good. No menu audio after disc is burned. Have tried several different transcoding options. There is menu video too that is working fine.

Here are notes I couldn't find before I posted that; just general re testing methods:
Mounting an iso (or building to a folder) is a great way to test. There are some differences, but it is a great method prior to burning to a disk. The main difference is simply computer vs dvd player - autoactivate on a button doesn't work with a mouseover, and you can be fooled into thinking your navigation does, or does not, work. (Even on the computer, don't use the mouse for testing, use the "remote" in the player controls.)
Encore preview is an emulator, like computer DVD players, that attempts to predict what will happen when a disk is played on a set top DVD player. It has always had issues with some predictions not being accurate. Some inaccuracies are like this one: Encore preview does not work, and a burned disk will. Others are the opposite; it works in Encore preview, and not in a DVD player. The point to be made here is that you cannot rely on Encore preview. You also cannot rely on computer playback of a built image or folder. And, in the end, you cannot rely on playback on one DVD player - some disks work on some players and not on others.

So what good is a disc image???

I did a search on this and saw nothing.
Very annoying; I've burned two coasters thus far from an archived Disc Image created in iDVD 7.x.
iDVD8 will not even load it, unless there's some &$^#%$ secret handshake-- why enable disc image burning in iDVD if the program can't even *&$%#$ open it and burn a fresh disc?
So I used the the desktop, loaded Audio TS and VIdeo TS into a burn folder. Pressed Burn button, selected 8X for the Mac Pro 10.5.8 burn. Verified correctly. When finished, ejected disk to test it.
Reloaded it.
It opens DVD Player and... does absolutely nothing. Press Play: NOT PERMITTED.
I figured out I have to go to the DVD menu, select Open DVD Media, select the disk folder to get play.
This is not what my clients are going to waste time trying to figure out, know what I mean??
So I tried DiskImageOpener utility. Same result.
This is garbage behavior-- who's Q/A in that department, anyway? Monkeys?
As always, advice appreciated.

Hi
It's always waste of time to use one tool to do another thing wich it's not supposed to do.
DiskImage is as I get it and use it
• a way to test a iDVD project before burning it
• a virtual DVD copy I can use as a master when making DVD copies - WITH APPLE DISK Util tool
or Roxio Toast™
What You created is a Data-DVD with video content. And as far as I know of - no
DVD-player is made to be able to play such a creature.
There are a major difference between video-DVD and data-DVD.
And - iDVD is not made for being able to open DVDs to make re-edits either.
Roxio Toast™ Can open a non copy-protected DVD to re-create an editable file
(with quality losses due to the .mpg2 codeing of video and audio)

Windows 7 Disk Image Burner went away

Somewhere I lost the built-in Disk Image Burner. It no longer appears in the context menu for an ISO file. It does not appear as a selection in Default Programs, nor in Assign File Types. Where can I find it and reinstall or reactivate it? In the context
menu for an ISO file, this appears"-exit -isowrite".
Assistance please

Hi,
Do you have any other CD\DVD burning software installed? If so, it could be that they've associated themselves with ISO files.
I would like to suggest you try to select the ISO file, then right clicking it, then selecting "Open With" and see if Windows Disc Image Burner is one
of the selections.
I also would like to suggest you uninstall any other CD\DVD burning software you have installed and see if it restores the Windows Disc Image Burner
option.

Any suggestions on how to correct this problen so I can continue burning my playlists???

Hi, I'e never heard of that error before!???
Is this purchased music, or your own music files?

Disc Image will not mount after format

I am trying to create a disc image from DVD Pro so that I can burn the final project at a low speed to avoid burn errors. Whenever I try to burn the image to DVD in Disc Utility it says that the file is not recognized. I have even tried to start the project from scratch and still am getting the same error message. Another weird thing that DVDSP is doing that is odd is when I am build and format, the log shows a ton of error messages saying that random files will not be included on the final DVD. Please help, I cannot figure oout what I am doing wrong.
Thanks,
Leon

Leon:
Warning: The file ‘2007KIAC_BBTOURNY.layout’ found in the VIDEO_TS or HVDVD_TS folder will not be included in the final disc.
Warning: The file ‘VOB_DATA.LAY’ found in the VIDEO_TS or HVDVD_TS folder will not be included in the final disc.
These are standard wraning. Nothing to take care about.
After deleting the old build empty your trash and try again. If DVDSP ask to reuse, you must be building to another location than where you think. Check that.
Hope that helps !

Problems burning DVD from iDVD disc image

I'm burning a disc image onto a DVD using Toast and can't seem to get the disc to automatically start or be read by either my home DVD player or my Powerbook G4 (through DVD player). I'm a little unclear if I burn the .img folder onto the DVD, the mounted drive containing the AUDIO_TS and VIDEO_TS files, or the AUDIO_TS, VIDEO_TS files themselves. I've tried all of these and none have worked, which made me think that it was something wrong with my DVDproj file from whence the disc image was made.
Do I have to have something in the box labeled "Drag content here to automatically play when disc is inserted" in teh MapView? I'd prefer it to just bring up the DVD menu.
Thanks!

Burning from disc image

Trying to replicate a DVD for which I no longer have the iMovie files - successfully created a 3.44Gb .dmg file, BUT when trying to burn from this, I get "buffer underrun" messages. There is >17 Gb free space on the hard drive. Also, I am unable to copy the .dmg file to an external drive with 18 Gb free space as after about 2Gb it fails with an error message that the drive is full. Something funny about that disc image file?

I am using Disc Utility as per those directions, and this has worked with no problems on similar DVDs.
I also suggest you get the free download Mac Sweeper which you will find on http://mac.softpedia.com/get/System-Utilities/Mac-Sweeper.shtml
Then:
1) Shut down/Restart without any applications running.
2) Run Mac Sweeper carrying out all the optimize options including repair permissions and, under clean, empty caches.
3) Now do your disc copy with nothing else running.
Onyx will have the same functions as Mac Sweeper. This is a bit of an overkill but it will give your system every chance of a trouble free burn.

Error when burning disc image

An error occurred when I tried to burn a disc image of a DVD slideshow. The slideshow has 324 slides in it and is almost 38 minutes long at the moment. I have added sound by creating a sound track in iMovie using a combination of songs downloaded from iTunes and tracks from my own CDs then blending the two blending the two. The slideshow plays on the computer and I have burned a disc image two or three times as I was creating it.
Any advice?

I have burned a disc image two or three times as I was creating it.
Can you clarify what you did exactly? You mean you saved the project as a disk image, then went back and did further work on the project?
The audio tracks you imported from iTunes may have been copy protected and will not burn in iDVD. The workaround is to burn those tracks to an audio CD in iTunes, then re-import into iTunes from that CD. Then will transfer to iMovie and iDVD without problems.
Also, something here may help:

Burn error (disc image)

All of a sudden, iDVD 5.0.1 won't burn a disc image. Gets to some point through the process (might be half way, might be right through), then says, "Burning completed. Some errors were found during the burn process". Doesn't create any file at all. Have tried buring a few different projects, with the same result.
Any clues?

I am having exactly the same problem. My iDVD project started in iPhoto as a "saved slideshow". I have followed all of the steps as provided in two 3rd party manuals -- Jim Heid's "iLife '05" and David Pogue's "iMovie and iDVD 5 -- the Missing Manual". I have even done a "Project Archive" file as the basis to burn the iDVD to ensure that all the resources are together and available. My project consists of a 24 minute slideshow comprised of 230 photos all with "Burns Effect" panning and zooming and with a background music track. This was sent to iDVD from the iPhoto commands. The "Memories" theme was applied with text modification, changes to the font style text location and color, and changed audio selection. A second slideshow was added which consisted of an archive of all the photos used in the original, plus some added ones that were not used. This added a second button on the main menue with three sub-menues on a secondary menu, where the photos were automatically broken down by iDVD into three groups of photos of less than 100 each for a total playing time of approximately 6 minutes (1 sec per photo). The project was then saved and archived. Everything plays fine up to this point. The total memory of the saved archived project file is 2.86 Gb. The rendering and processing time for iDVD to create the disk image (.img) file exceeded 5 hours. I've tried to generate the disk image three times. Like Jim White, in one case after nearly 3 hours, the program put out an error message saying that errors had been encountered and the processing was being aborted. In the two other cases, the processing went the complete 5+ hours; gave a message that the "burning was finished, but that some errors had been found (on verification?) and produced NO FILE.
I am using a Mac G4/1.25 Ghz MDD , Mac OS-10.4.2 with 768Mb RAM and 13.5 Gb of available hard drive storage at the beginning of disk image processing; with iPhoto 5.0.4 and iDVD 5.0.1.
I have no experience with earlier versions of iDVD, so I can't say if this is a problem created by the 5.0.1 update, or the upgrade to Tiger. In any case, this is extremely poor error coding, especially considering the amount of time required for the image processing -- i.e.to state after 5 hours that an error was found which aborts or invalidates the burn without providing any clue as to what or where the error was -- this makes the entire software package of virtually NO VALUE.
Your comments, please!

Creating project as Disc Image after 1 1/2 hours it appeared to be finished but there was message that there was a multiplex error. Checked and no yellow triangles, music on computer, any ideas.

Creating project as Disc Image after 1 1/2 hours it appeared to be finished but there was message that there was a multiplex error. Checked and no yellow triangles, music on computer, and all resources on computer, any ideas??

Hi
And
• free space on Start-Up hard disk ? How Much ?
• Brand and type of DVD used
• Burn Speed ?
• Did You try to first do a "Save as a DiskImage" ? If so - Did it work ?

Error-29, Cannot burn a DVD or save a disc image from within FCPX using Mountain Lion

Really stumped on this one.
Running Mountain Lion, freshly downloaded version of FCPX, on a 2009 MacPro with 16 G RAM.
Trying to share a 4 minute movie I edited.
- No problem exporting as a quicktime move...worked fine
- Big problem trying to either burn a DVD, save a disc image, or export to an Apple device.
The progress bar gets about 90% complete, and then it stops and a message window comes up that says:
There was an error burning your disc. The operation couldn't be completed. (DSPPublishing error-29)
Thoughts?

From Crash Analyzer:
DSPPublishing error -29 (Final Cut Pro X)
This error can occur when burning a disc if your menu has incompatible assets.
Suggested Actions
If your menu has a background image, make sure the image is not too large. Try reducing the size of the image and saving it as a JPEG or PNG.
