![]() ![]() ![]() Quite a lot of highly technical work goes into creating a DVD-in the background. True, it's not the same as seeing the picture at high-definition quality, but it's a start. In the meantime, iDVD imports HD projects with ease and converts them into widescreen DV format. (Software such as Roxio Toast can do so, with the addition of an external Blu-ray disc burner.) As such, iDVD does not support Blu-ray either. Blu-ray may have won the HD format war, but currently no Macs support burning to Blu-ray discs. Burn the VIDEO_TS folder with LiquidCD.IMovie can create HD movies, but don't expect to create a high-definition DVD for now.While playing the video you replaced, make sure the sound, seek bar, and Menu button work. Play the VIDEO_TS folder with both VLC and Apple DVD Player.Use Select All with copy and paste to copy the iDVD menu navigation pre and post commands from the iDVD-authored placeholder menu PGCs to the replacement video.Make new empty PGCs in the menus as needed to make the same number as in the iDVD-authored IFO.myDVDEdit will probably report and fix some errors in the modified folder that’s normal and good. Open both the unmodified and modified VIDEO_TS folders in myDVDEdit.Replace each placeholder VOB and its IFO and BAK files with the real ones in the duplicate VIDEO_TS folder using the Finder (renumber their file names as necessary).Open myDVDEdit on the VIDEO_TS folder to figure out which VTS number each placeholder video is.Duplicate the VIDEO_TS folder in Finder.Include a short dummy video in the iDVD project as a placeholder.If you have an MPG file or a VOB with no IFO, demux and remux as needed to make a VOB and IFO, using a program such as ffmpegX.To include videos that are already encoded as DVD-compliant MPEG2 in an iDVD project (assuming they don’t need chapters):.Burn the VIDEO_TS folder with Burn or LiquidCD.Use myDVDEdit to check and fix the aspect ratio in each VTS (either 4:3 or 16:9 auto Pan&Scan and Letterbox).If you mix 4:3 and 16:9 videos on one DVD, iDVD will probably mix up some of the aspect ratios.Preview the DVD to make sure it looks the way you want.In Lion, you need to download it from Apple. In Snow Leopard, QuickTime Player 7 isn’t installed by default, so you might need to install it from the Snow Leopard DVD (it will end up in the /Applications/Utilities folder). Pre-Snow Leopard, you might need to buy a QuickTime Pro license. You can avoid modifying the DV file by saving a QuickTime reference file with the 853×480 display size. The workaround is to change the display size of the DV file using QuickTime Player 7. iDVD does not support anamorphic widescreen DV files, interpreting them as 4:3 instead of 16:9.If the movie has chapter markers, iDVD won’t update the project correctly you need to remove that movie from the project, probably quit iDVD and relaunch it, and re-add the movie. If you update or re-render a movie you have added to iDVD, iDVD will detect the change and offer to update the project. ![]() I usually turn off the menu sound for each menu, by dragging the sound out of the Inspector box.After changing a menu background (even to a still image), make sure the loop time is still zero iDVD seems to reset it. Or, less drastically, in themes with animated thumbnails, you can select the Inspector boxes to use a still image instead. To save encoding time and space on the DVD, you can open the Inspector (command-I) on each menu and uncheck the boxes for the various animated effects and bring the loop time down to zero.The default menu in iDVD 7 can take longer to encode than the movies do. Turn off the Apple watermark in Preferences.For details on the iDVD encoding options, see What iDVD ’08 Compression Options Really Mean and Review: iDVD ’08 and iDVD 7. If you have time to wait, you might as well get the highest quality encoding. If possible, select Professional Quality (2-pass VBR) in the Project Info.It’s a pretty easy way to get attractive menus and excellent looking rendered video, but it does have some annoying limitations and bugs. For authoring a DVD of home movies, my preferred program is currently iDVD 7, which is part of iLife 08 and 09.
