It's funny you mention this, as I've seen others have a similar issue with iPhoto pictures upsetting a project. The behavior usually follows a pattern of, "I was adding pictures and suddenly, every time I would skim the video it would freeze on the first picture and won't display any of the other photos". Knowing that you had a visual cue of some sort indicating there was a problem with particular clip is a big help though. With the imported photos I usually recommend people do a Reaveal in Finder, open the picture in Preview, make a small adjustment and save it back on top of itself again. Sometimes this will clear it up. Other times I recommend making a duplicate project, and start deleting stuff out of it until the ability to skim and get a live preview of the Project comes back. Kudos to you for trouble-shooting this though, I'm sure a lot of other iMovie folks will benefit from it.
Trying hard to identify any clip that might have such triangle. No luck so far. And this is my last day to present my home movie to my family ... so frustrating. I was able to add a background on the first portion, a sound on another area and now the third song just doesn't play... no matter where I try to insert it.
******I HAVE A SOLUTION******
My original issue was a change in my iTunes playlist resulted in no sound on my project in iMovie. I deleted all of my soundtracks that played over the footage and added them back in and still no sound!
I solved my problem by deleting all of the soundtracks on my project then returned back to the Project Library and double clicked and pressed Duplicate Project. I then went into the duplicate project and add the soundtracks. Problem Solved!!
I hopes this helps someone out there!
I had the same problem half way through (at this point 34 minutes) all added sound tracks were silent. I went through the entire project and found one added track (added from my iTunes music file) that had a yellow triangle with an explantion mark in it. I deleted that track and reinserted it once again from iTunes. All sound tracks are now working fine. Hope this information helps a few of you .
Hi everyone, I had the same problem with iMovie. After going back to a nearly completed project three audio clips wouldn't play. As it turned out, only one clip was corrupt but there was no warning triangle to identify it initially. However, this is what I did and suddenly all was well - hope this helps someone!
If Audio Clips suddenly don’t play back for no good reason, fail or corrupt in iMovie
Check you have all the audio clips you require safely tucked into iTunes, if not, put them in there and check they all play back as normal.
Shut down all Applications, including iMovie.
Shut down the Mac completely and leave switched off for at least 20 seconds.
Reboot the Mac.
Open iMovie Application.
You should now miraculously see an ! ( exclamation ) mark in a yellow triangle on the corrupt audio clip or clips.
Delete that clip or clips that show the ! mark in the yellow triangle.
Any remaining audio clips should now play correctly - check that they do.
Rename the rogue clip/s in iTunes - this “fools” iMovie into thinking these are brand new
clips with no history of having anything “wrong” with them.
Re import the previously “rogue” clip, or clips, under the new name/s back into iMovie
and back into the formerly occupied position/s and, hopefully, all should be fine!
I had kinda like such a problem; all audio fragments before 2 framents wich source was missing (they had an '!' exclamation mark) looked fine but didn't make sound. (after the 2 framents where just fine)
Solution for me; remove the 2 fragments with the '!' exclamation mark and all audio produces sound again
Stumbled on a solution.
Don't ask me why this happened, but after reading all of these posts raising and trying to solve the problem of audio voiceovers and iTunes music suddenly not playing in my project, I was trying to cut and paste each clip to a fresh project. I quickly discovered that my very first clip, a freeze-frame with no audio from the first couple of seconds of the first clip, wouldn't copy and paste. It was a 4s freeze frame, so it didn't have any yellow triangle or turning color wheel.
Since it wasn't cooperating, I simply deleted it and replaced it with an Add Still Frame to Project from the Event Library.
Note to Apple monitors: All the audio miraculously started working. Go figure out why that Freeze Frame fouled up the entire project.
There are obviously things you can't do in iMovie which nobody seems to know you can't do until they cause big problems.
This thread saved me! I could not get any audio attached to a clip to play at all (waveforms were visible etc). I had one clip with a yellow triangle and exclamation mark on it. After deleting that, everything is working again!
Thankyou so much everyone on this thread - it's so wonderful to be able to fix this!
