Hi,

 

I'm currently using what I think is the '06 version of iMovie (version 6.0.3).  I just finished creating a project that consists of pictures, audio recordings of my voice, and music.  When I play the video in iMovie everything works perfectly.  However, after I try to export the video at about 1 minute in, the voice recordings I made and the pictures get out of sync.  The audio lags behind a couple seconds, but because my words need to match the pictures, it's a little bit of a problem.  Any idea how I can fix this?  I have gone through a ton of forums and a lot of them talk about extracting the audio from the video clip. My Audio and picturees are already separate, so this obviously will not fix my problem.   I need to submit this as an assignment for a class, so i'ts important that I figure out how to solve the problem. 

 

Thanks for your help!

iMovie '08, Mac OS X (10.6.8)

    I am having the exact same problem, and have contacted numerous Video Services stores in my area to resolve.  As I have a massive project, the last thing I want to do is rebuild the entire thing from scratch.  I am attempting to export the audio for the entire project seperately, likewise for the video.  Then, in a second imovie project, import both the audio and video export back into imovie to synch manually.

    Your problem may not be exactly the same as that of the original poster of this thread, and it can be very confusing for everybody if we try to answer more than one question in each thread.

     

    In order for us to give your problem our undivided attention to try to solve it, would you kindly start your own thread, describing the trouble you are having in the fullest detail, including completing your details to show what Mac you are using, what operating system, and what version of the application in question.

    Hi

     

    Tedious situation.

     

    To avoid this I'm kind of strict in Audio in two ways

     

    A

    • Material used if video is in same frame per minute - else I use JES_Deinterlacer to convert all to one standard. I use PAL = 25fps - one of my Cameras records ONLY in 30fps - (some people records in 24fps - to get a movie feel - I never)

     

    So keeping the fps from Camera to (in my cases) DVD - gives a supperior result

     

    B

    • I'm strict in the kind of Audio formats I use - ONLY .aiff (or from miniDV tape Cameras) AND THEN 16-bit 48kHz or from Audio-CD (still .aiff as on normal CDs) and here 44.1kHz

     

    If Camera is set to record in LP-mode or 12-bit Audio - Then I use an external Audio Editor to get this right

     

    If from iTunes - I never use this directly - BUT - collect needed audio into a New PlayList - BURN THIS as a Standard Audio-CD (NO .mp3 - but .aiff here too) and then use the files on this CD in my movie project's in iMovie HD6 or FinalCut any varsion (or if forced to - iMovie'11)

     

    Else read this

     

    Audio Sync problems

     

    • 12.bit - should be 16.-bit (from miniDV tape - set Camera right)

    Avoid recording in LP-mode on miniDV tape. This tape must be play-backed by same Camera. When Camera dies

    so does the video material in worst case.

     

    • .mp3, .avi etc strange file formats - should be converted to .aiff 48kHz 16-bit

     

    • in iMovie (up to HD6) - do - Extract Audio - it most often helps

     

    • from iTunes - collect into a PlayList then Export out as an Audio-CD (not .mp3) and use the files on this (.aiff 44.1kHz)

     

    • There seems to be a problem with slow-down resp speed-up. Has to be in specific steps as 25% 50% 150% 200%

    else problems will arise

     

    • Audio problems when transitions is in use - especially iMovie HD/HD6

    a. Select video clips

    b. Extract Audio (Advance menu/Extract Audio)

    c. Now apply transition

    d. eventually fine-tune end and start of extracted audio clips

     

    Yours Bengt W
