Hi All,

I am having some trouble making a useable DVD. I have a video that I recorded and imported into iMovie (2h33m long). I exported it to iDVD, which told me that I needed to use a dual layer DVD to make it fit. Here's where I noticed the first problem: iDVD has one option for a dual layer disc, stating that it has 7.7GB storage space, and my discs have 8.5GB. I set it to use the standard setting for the DL disc any ways, turned the quality down a bit to make it fit, and burned the DVD. After burning two discs, I still do not have one that works. It comes up as "supported disc not available" on my Mac, and as a blank disc on any other machine I put it in. It will run on my coworker's brand new iMac, but that is the only one. Am I doing something wrong? The only mistake that I have corrected since I have tried all this is changing the aspect ratio back from 4:3 to 16:9 in iMovie (I am not sure how that happened, as the video was originally recorded in 16:9). I am re-exporting the file to my desktop now in the proper ratio, and changed the quality to HD. I am waiting for the file to encode as we speak. Any help would be greatly appreciated, as this work is for my local school board and is very time sensitive.

 

I am running a 28" iMac, 2.66GHz Intel i5, 8GB RAM, 1TB hard drive on OSX 10.6.8.

iDVD 7.1.2, Mac OS X (10.6.8), iMac, 2.66GHz i5, 8GB RAM

    I set it to use the standard setting for the DL disc any ways, turned the quality down a bit to make it fit, and burned the DVD.

    That part I don't understand.

     

    iDVD encoding settings:

     

    http://support.apple.com/kb/HT1502?viewlocale=en_US

     

    Short version:

     

    Best Performance is for videos of up to 60 minutes

     

    Best Quality is for videos of up to 120 minutes

     

    Professional Quality is also for up to 120 minutes but even higher quality (and takes much longer)

     

    That was for single-layer DVDs. Double these numbers for dual-layer DVDs.

     

    Professional Quality: The Professional Quality option uses advanced two-pass technology to encode your video (The first pass determines which parts of the movie can be given greater compresson without quality loss and which parts can’t.  The second pass then encodes those different parts accordingly) , resulting in the best quality of video possible on your burned DVD. You can select this option regardless of your project’s duration (up to 2 hours of video for a single-layer disc and 4 hours for a double-layer disc). Because Professional Quality encoding is time-consuming (requiring about twice as much time to encode a project as the High Quality option, for example) choose it only if you are not concerned about the time taken.

     

    In both cases the maximum length includes titles, transitions and effects etc. Allow about 15 minutes for these.

     

    You can use the amount of video in your project as a rough determination of which method to choose. If your project has an hour or less of video (for a single-layer disc), choose Best Performance. If it has between 1 and 2 hours of video (for a single-layer disc), choose High Quality. If you want the best possible encoding quality for projects that are up to 2 hours (for a single-layer disc), choose Professional Quality. This option takes about twice as long as the High Quality option, so select it only if time is not an issue for you.

    Use the Capacity meter in the Project Info window (choose Project > Project Info) to determine how many minutes of video your project contains.

    NOTE: With the Best Performance setting, you can turn background encoding off by choosing Advanced > “Encode in Background.” The checkmark is removed to show it’s no longer selected. Turning off background encoding can help performance if your system seems sluggish.

     

    And whilst checking these settings in iDVD Preferences, make sure that the settings for NTSC/PAL and DV/DV Widescreen are also what you want.

    You should certainly burn at only 2x or 4x for the best results.

     

    Memorex has a poor reputation around here. Most of us get the best results with Verbatim and Taiyo Tuden.

     

    I have used Verbatim DVD-R DL with good results.

    Hi

     

    first thoughts

    • Burn Speed - I set to x2

    • Brand - I only use Verbatim (very common problem maker)

    • FREE SPACE - on Start Up (Mac OS) Hard Disk - for SL-DVD I NEVER go less than 25GB and DL a safe level should be 50GB

    • If Export to Media Browser and as Large fails - Then Use MEDIUM - Never HD or other as resulting DVD will look BAD

    • If HD material is imported into iDVD it use to get problems as - DVD is as Standard - Interlaced SD-Video (whatever authoring program is used) - and need of free space will increase by 4 - 5 times on booth hard disk.

     

    Error -2125

     

    OK Error code - 2125 usually indicates that the movie is to large.

     

    It use to pop up when going to iDVD !

     

    iDVD - DO NOT CARE ABOUT Gbs at all. I got movies on 500Mb that do not fit and 50Gb that fits nicely.

     

    iDVD - ONLY CARES ABOUT - Duration. Duration is Movie time + MENU TIME. Choice of

    menu and animation of this can take lost of "DURATION" 15 minutes or even more.

     

    Choice of encoding method and use of SL or DL DVDs determine the DVD limit.

     

    iDVD 08 & 09 & 11 has three levels of qualities.

    iDVD 6 has the two last ones

    • Professional Quality (movies + menus up to 120 min.) - BEST

    • Best Performances (movies + menus less than 60 min.) - High quality on final DVD

    • High Quality (in iDVD08 or 09) / Best Quality (in iDVD6) (movies + menus up to 120 min.) - slightly lower quality than above

     

    DL DVDs can store about double of these times.

     

    ALTERNATIVE - The Error Code can indicate that free space on Start-up (BOOT) hard disk is

    less than 25Gb (my minimum)

    If you are getting OSStatus error -2125, I've seen this caused by the computer display sleep settings.
    Try changing the sleep settings to never and see if you are able to export.

     

    Yours Bengt W

    It is NOT a question of resolution, it is NOT a question of file size, ONLY a question of length.
