Hello, I am new to iMovie and iDVD.

Following a manual's instructions, having made a DVD in iMovie, I commanded share>iDVD and waited 2 hours for iDVD to open with this project (which seems too long?), but the movie has no audio at all....

The original footage was MP4 from a Flip video camera.

Can anyone explain what is wrong and how to correct this? Thanks, Andy

iDVD '08, Mac OS X (10.5.8)

    Hi

     

    There are several things to this

    • Video Codec used - .mp4 is no specific video-codec but a Container (sort of folder) and can hold codecs iMovie can use or CAN NOT.

     

    open the .mp4 file with QuickTime-Player - then

    open Inspector [cmd+I] and read

    - Video Codec/Format : nnnnnnnnnnnnn

    - Frame Rate : YYYYYYYYYYYY

     

    What does it say

     

    • Then - How You go from iMovie to iDVD matters !

    - I never use "Share to iDVD" as resulting DVD will lose lot's of quality

    - I do - "Share to Media Browser" and as Large OR Medium (Never HD or other resolution as this too degrades the final DVD (downscaling is done badly)

    - Large or Medium matters and sometimes Large result's to me in partial audio loss - so Medium is a safer resolution.

    - I Always - Save as a DiskImage - Test this with DVD-player tool - then use Disk Util tool to burn it to DVD

     

    I always

    • set down burn speed to x4 or less = less burn errors = plays better and on more devices

    • use High Quality DVDs - only Verbatim for me

    • DVD-R - never DVD+/-RW or DVD+R - as the first usually don't work and the latter only on newer DVD-players

    • SL-DVD - not DL-DVDs - my personal problem with my Macs inabillity to like these

     

    Yours Bengt W

    although when I began it yesterday it said it would take 25 hours!!! so I aborted.

     

    A. iDVD - does this calculation very bad - can be much less (and even much more). I don't look at it.

     

    B. When things goes ridiculously slow it use to be due to (for me)

    • Less than 25Gb free space on START-UP Hard Disk (others do not count)

    • using material iDVD or iMovie can't use as is e.g. video-codecs, audio and photo file formats

     

    TO GET IT TO WORK SLIGHTLY FASTER

    • Minimum of 25Gb free space on Start-Up hard disk

    • No other programs running in BackGround e.g. Energy-Saver

    • Don’t let HD spin down or be turned off (in Energy-Save)

    • Move hard disks that are not to be used to Trash - To be disconnected/turned off

    • Goto Spotlight and set the rest of them under Integrity (not to be scanned)

    • Set screen-saver to a folder without any photo - then make an active corner (up right for me) and set

    pointer to this - turns on screen saver - to show that it has nothing to show

    • No File Vault on - Important

    • NO - TimeMachine - during iMovie/iDVD work either ! IMPORTANT

    • Lot's of icons on DeaskTop/Finder also slows down the Mac noticeably

    • Start a new User-Account and log into this and iMovie get's faster too - if a project is in a hurry

    • And let Mac run on Mains - not just on battery

    BTW - I try to not Panic/Force Quit as much possibly - as this build up small errors in pref files and elsewhere to finally result in a Major Disaster.

    Yours Bengt W
