IMovie 11 export audio sync bug - URGENT

I've read up the other threads, I've tried detaching audio, I've tried 'Optimizing' all my clips, and nothing works. My imported MP4s are simple and undemanding, my cutaways equally simple, I've done NO speed changing, and still the audio and video sync drifts out, to the extent that the last half of my 10 minute video is unwatchable 8-(
And, to PROVE it's a bug in the latest iMovie 11 update, I went back and re-exported a project from just before Christmas. And THAT now exports with sync issues too, whereas at the time it was 100% perfect.
Is there a way to roll back iMovie 11 to before the update? I do have a Time Machine backup of my Mac....
Either way, Apple PLEASE pull your finger out - this is a CRITICAL bug as far as I'm concerned.

I am not sure you guys are quite understanding my imovie concept. Sure you do not need to change the speed settings for you're movie, but it's the easiest way to convert the clips to be fully compatible with the project. Just try converting the clips (double clicking each clip and clicking on convert) and tell me if that does not work for you. Trust me. Try it before you leave a comment saying that you dont need speed changes....
I don't see any convert option. When I double click the clip, the inspector HUD pops up. It has 3 tabs, "Clip", "Video", "Audio". None of them have an option to convert. Do I have to enable some advanced feature for this?
Furthermore, other folks have suggested a File->Optimize->Full.
For the videos that I am working on, both the Full and Large options are grayed out -- I can't click on either.
I tried for some recent iPhone videos and I could "Optimize" them, but like I said, my problem of out-of-sync is with some old videos.

Is the audio sync bug (related to custom clip speeds) still present in iMovie 11?

Is the audio sync bug (related to custom clip speeds) still present in iMovie 11? I encountered it in 09 and was wondering if it was fixed in the latest version.

I haven't encoutered since iMovie '09.
You can always call Applecare as ask if there have been reports to engineering.

Open the movie in the QuickTime Player and Select Export -> Sound to AIFF.
Drop the exported AIFF file into iTunes.
Make sure the iTunes CD Import Settings in Prefs is set to the MP3 encoder.
Right-Click on the AIFF file in the iTunes Library display and select Create MP3 Version.

HDV imovie projects lose audio sync when burned in idvd

I have 80 min. HDV projects from imovie sent to iDVD, after burning them onto dvd they play fine then lose audio sync after about 60 min. or so.....

Painful in iDvd to do interviews when they happen to fall over the 60 minute mark, isn't it?
If it's of any consolation, it's more reliable in Apple's FCS2 / FCP => DVDSP.
Toast might be another option worth looking at....
Good luck on this.

Slideshow Export, Audio Sync problems

Has any fix been discovered or introduced for the Keynote ('09 in this case) timing issues. The specific problems I experience:
- Keynote "Play" function, on successive plays of the same slide show yields different timing of sequenced transitions (between builds & slides) which gets worse the further into the presentation the sideshow runs.
The best solution I've found for this is to restart my computer . . . which seems to reset some clock, and then gives roughly the same timing of events.
- Keynote "Export" seems to totally throw off all timing in the exported file, and I have no way of guessing how it will match with my previously synced audio.
My only solution for this is to edit it with Final Cut . . . but then this seems to mess with the color, and degrades the image.
Anyone "expert" of Keynote export and syncing issues? Could use the latest pointers, if there are any to share (which I have missed) . . . Thanks much!!

Holy cow, that was easy. You were right, that worked. Doooh.
Thanks.

IMovie iOS export Audio out of sync

I've just bought iMovie for iOS version 1.4.1, which I believe is the latest.
After making a project, I exported the movie with HD720p video size.
I used mainly photos and short videos, as a clip of my travel. I used background song,
Problem is, after I exported, the audio goes out of sync.
The photos and videos changed sequentially, in sync with the audio when I play it in "project"
But once I exported it, the audio goes a little bit earlier than expected - around 0.5 seconds earlier.
Any help or solution to this problem?
I'm running iPad 4 with the latest iOS (6.1.3) and iMovie 1.4.1.
Battery is at 13% at the moment.

Well I tried importing the .mov file that is correct into iMovie but no matter what I tried (I did optimized- full quality, optimized- large, and not optimized, and I also copied the .mov file out of the iMovie Events folder to somewhere else and renamed it), the video and audio didn't match up in the clip in iMovie. The video was always off. Any suggestions?

Adobe premiere elements 10 audio sync bug (mpeg2)

Hi
Right im trying out diffrent video editing software and reviewing them. There is an annoying bug or flaw when it comes to importing mpeg2 files. The audio track becomes delayed about 1 sek after a while, its synced in the beginning and the get out of sync at the end of the clip. I tried the same mpeg2-files on other video editors including: Pinnacle studio, Vegas, Corel Studio, Cyberlink Powerdirector and the audio is perfectly synced all the way.
So, obviously its a problem/bug related to Adobe. I remember I had similar problems with Premiere pro and compressed videos, audio tracks dissapearing etc.
Im gonna try the trial for Premiere Pro to see if it has the same problem as elements.
Besides this, I kind of liked the interface and workflow in the program. So its bad that it cant handle a common compressed format such as mpeg2 that all other popular editors out there can.
Kind Regards,
Jonas

Well, with licensed modules, like CODEC's, and plug-ins, it is often just an "activation" issue. Rather than for the NLE company, whether CyberLink, Magix, Adobe, et al, to just give the fee to the licensing agent (say MPEG-LA) for every copy of the program, whether trial, or full-price, they limit the trial versions, and then with their full-paid version, the user will activate that module, and this normally happens transparently. When the module gets activated, the licensing organization gets notice, and then back-charges the NLE software company.
This sort of thing was carried to the extreme with the Pinnacle Studio programs, where "samples" of every conceivable module was included in the program. However, those were just previews, and could not be used, until the user contacted Pinnacle, and then bought an unlock code for each module (often sold in packages). The program cost around US $ 100, but to unlock all modules, it would cost about US $ 500 additional. As there was nothing but unlock keys, the user had to guard those well - no discs, or media. Also, Pinnacle did a fair job of keeping records of users' keys, though some did get lost over time. Also, keys did not always work version to version, so an upgrade could render key purchases useless.
With the DD 5.1 SS Minnetonka Audio SurCode plug-in for PrPro, things are slightly different. Adobe includes a limited version of that encoder plug-in - the user gets three trials of it. To activate the plug-in, beyond those three uses, the user must buy the key from Minnetonka, and it's now about US $ 300. Most of that cost goes to Dolby Labs, and in this case, Minnetonka just sort of is the "banker," sending the $ to Dolby, when they SELL that plug-in key.
Different companies handle "trials" differently. Some, like the Minnetonka SurCode, give limited, unencumbered uses. Some limit by time, and give unencumbered use, during that time. Some use a watermark, or similar, until the user buys it, and then the watermarks are uncoupled. Some just limit the features in the trial, and those limitations are lifted, when one buys. There are pluses and minuses to each scheme. However, each is designed to let a user try something, and no royalties are paid, until they buy it.
Good luck,
Hunt

Losing audio sync?

When I import my clips to iMovie the sound track loses sync with the picture.
Often it starts off OK but loses it in the middle of the clip and then catches up again at the end.
Does anyone know how to stop this happening?

For whatever it is worth, I personally have never experiences audio sync issues when importing or playing back within iMovie. My audio sync problems have always been when going to iDVD or when exporting back to digital tape. In those cases, I have always been able to fix the issue by selecting the entire movie and using the extract Audio command right before going to iDVD or back to tape.

Major "BUG" in Imovie 9 - Audio Sync Problem on Export !

Well I'm a hard-core Apple user from day one, but unfortunately today I'm not to proud about the latest version of Imovie 9.
It seems there has been a "MAJOR audio sync problem on export" in Imovie 9, since July 2009. Apple knows about this bug for a long time now, but didn't release any bugfix yet!
Here's what it's all about:
It seems if you use the (custom /manual) speed-adjustments and not the preset slider speeds, you will experience (after exporting your movie) annoying bursts of audio from clips that had been set to mude. The strange thing is that you will only experience this audio-bug after exporting, you will NOT experience it in the project playback mode!
Here's what you can do:
Find ALL the clips in your Project that are Speed Adjusted.
Instead of using a "Custom Speed" percentage, use any of the "Preset Speeds"
Preset Speeds on the Slider = 12.5%, 25%, 50%, 100%, 200%, 400%, 800%
Then, export your project as usual.
No more sync issues.
Really hope That Apple will come up with a real BUGFIX soon.
It's a shame that a major bug in a otherwise GREAT PRODUCT, hasen't been fixed yet!
What's wrong with Apple?...this is not one of their finest hours.
Still A BIG fan from Imovie HD,...I'll chance to Imovie 9 when the bugs are finaly fixed!

This is TERRIBLE! I have spent so much time working on this project, and I really don't want to adjust the speed settings to the preset levels, BECAUSE I need to motion of the video to match certain musical points. I can't re-film my video, and I needed this project done TODAY. I made a music video with some kids at summer camp, and today is the last day- the day we were supposed to all watch it together, and now, I've got NOTHING!!!! (Because I can't export it without all those glitches!)
I am MAJORLY DISAPPOINTED on this one. I've made movies in windows movie maker before, and purposely used imovie, because you know, everything on macs is supposed to be better. Well, I guess I was wrong.

Exported Final Cut XML from Imovie09 causes loss of Audio Sync

I have recently upgraded to ILife09 and tried a process that always worked in ILife08 but now get Audio Sync problems.
I have created an Imovie project that is 2hours and 50 mins long and wanted to export it to Final Cut Express as XML. This used to work 100% with Imovie08. However, with this latest version of Imovie, when exported to Final Cut Express, the first 45 mins of the XML movie is well out of sync (Audio / Visual).
Has anyone experienced this?

Hi Roberic,
there is a bug in iMovie '09 that causes loss of audio sync when you use custom slow/fast motion. This has been experienced by many users. See for example this thread:
http://discussions.apple.com/thread.jspa?messageID=9152271
I don't know if this applies to exports to .xml but it could well be that your problem lies here. There are some workarounds, being the easiest one to only use what the slow motion slider snaps to instead of entering custom speed percentages.

An old "export audio to movie" bug returns in 9.02?

Hey
Maybe it's just me, but I could've sworn they'd fixed this one...
I remember for a while when you'd use the "export audio to movie" feature, the sound would sometimes be about half a second late. Then that was apparently fixed... But now it's back again in 9.02
My previous work around was to bounce the audio mix, then drag it back into the timeline as a stereo .aif file. I'd solo that track, make sure PDC is set to "ALL" then use 'Export Audio to Movie'.
And - before you ask - no, there were no latency inducing plugs on the master output bus. No limiters, gates, in fact no plugs at all on this particular project.
No matter what I did, the Quicktime bounce was always out of sync. When I just 'play' the project, the 2-pop from my audio and the video cue beep/flash frame line up perfectly. Everything plays back fine. But when I use "Export Audio to Movie", my Logic soundtrack is about half a second late throughout.
Anyone else notice this? Any suggested fixes?
I know some people are having a great time with L9, but I'm sorry to say I'm solidly in the "sorry I upgraded" camp.
I'm starting to appreciate L8 more every day...

iSchwartz wrote:
You can work around this problem in QT without having to deal with Logic at all, provided your film has a timecode burn. Open the movie in QT. Trim it down if necessary. Assuming your 2-pop is what your cue starts off with (with no dead audio before it), open your 2-mix in QT, select ALL, CMD-C copy. Now your mix is in the clipboard. Back to the movie window, set the playhead of the movie so that you're seeing the desired start frame. Use CMDOPTV to place the music into the movie. Trim the movie as needed. Export.
If you want to save the movie, be sure to save it under a new name. Saving as a proxy (reference) will save disk space.
Good tip - thanks. Unfortunately, this film doesn't have a time code burn. And while I've used the method above in the past, I always find it a little finicky to make exact trims in QT because you don't have the fine frame-by-frame control sometimes... I think.
But the thing is, I exported audio to movies with perfect sync all summer long in L8. I did about 60 cues for one client this summer, all with quicktimes, and not a single problem.
Now, since "upgrading" to 9, I can't get the audio to export with the same sync it has on playback no matter what I do. Sure seems like a bug to me....
I'm going to try some more experiments today if I get time. I want to see if changing buffer sizes or PDC settings has any effect....
Hm.

Export Audio to Movie - NOT IN SYNC ANYMORE in 9.1??

This is either a major, major bug or I am completely out of it.
When I do an export audio to movie command, the resulting Quicktime movie has the audio and video not synced as they were in Logic.
I have just upgraded to 9.1 and Snow Leopard 10.6.2 this week. I am having this problem with the 32-bit version of Logic.
Most of my sessions have the movie start time pushed forward or back to suit the start of the audio. I had NO problem in 9.0.2 with this feature.
ALSO.... what's the deal with the the 64-bit Audio bridge plug-in windows? Do we always have to do a double-click to open the actual GUI now-on? Totally s**ks.
Thanks.

Are the movie start times and sequence start times the same? For example, do both the music and the audio start at beat 1, bar 1?
I've found that Logic 9 doesn't maintain the same sync that your project has. In other words, if your video doesn't have a 'pre-roll', but your audio has a one bar count in, then the "bounce to movie" feature will have audio that is out by 1 bar. It's kinda dumb, because Logic should be smart enough to know you want to export the same audio/video sync as you have in your project. But alas it doesn't work that way...
Other possible culprits are latency-inducing plugs on the master bus, like limiters and 3rd party DSP plugins (UAD, Duende, etc).
One workaround I've started using is to bounce my audio mix first, then bring it back on a clean track and trim it to start on the exact same frame as the movie. Then solo the 'mix' audio track and "export to movie" (being sure to bypass any master buss plugins first, so the mix doesn't get processed a 2nd time). this usually works, and also makes it easier to keep track of revised mixes as you go ahead (just make copies of your 'mix' track and mute earlier versions).
good luck.

Help please... Audio sync issues going from iMovie to iDVD (iLife '09 packa

I've tried technical support, I've tried looking online but nothing seems to have helped, so here's the problem:
I have a video/movie, that is around 58 minutes long, I share it to iDVD and the other media formats from iMovie. The vid has music, transitions, titles, credits, etc... It plays fine in iMovie while I am editing it. The problem comes when I try to export it to another media format and to iDVD.
There's a section that has major audio sync issues that I have no idea how to even begin to fix. There is audio and music from the 55 minute mark that plays over the 27 minute mark for a good 3 minutes of video and audio.
I've tried some of the suggestions I've come across but nothing seems to work. Does anyone have anything that they can offer this very frustrated guy? Please and thank you in advance.

I don't shoot 12 bit audio (ever) so I'm not an expert on fixing it or converting it back to 16 bit audio. I can only report what others on this forum claim to have worked (in some cases with marginal success).
The ones that comes to mind are:
1. video and audio extraction in an attempt to re sync.
2. exporting back to the camera from iMovie and then re-importing as 16 bit.

Audio Sync Issue When Exporting to Quicktime

Currently using Premiere Pro CS3 3.2 and Quicktime 7.5.5
When I export to a quicktime .mov, my audio is a few frames out of sync. I've tried downgrading to older versions of quicktime with no success. Everything is completely in sync inside Premiere. If I import my rendered out-of-sync .mov back into Premiere, it magically syncs up fine again. It's the weirdest thing.
Help!

Scott:
There is a workaround.
I never really found a solid cause/solution, but if you're noticing that you have a couple of white frames at the end of your Quicktime exports, then you're probably suffering the same problem I have. Tech people I have checked with have suggested that the problem may be related to the use of .mp3 sound files (as opposed to .wav) in the Premiere project, but after removing them and replacing them with .wav's the problem persisted.
I am not technical enough to figure out exactly what's causing the problem, but I think it must have something to do with the Adobe Media Encoder (at least how it works on my computer). From what I've read on the subject, the Media Encoder is Premiere's Achilles's Heel.
Changing versions of Quicktime did nothing. Others trying to solve this problem have tried exporting their files with every conceivable variation of options and settings in the Adobe Media Encoder with no positive result.
I'm not the only one with this issue, but searches of the Internet show it to be relatively rare, so it's probably some weird glitch somewhere deep in my system. It's not widely-reported enough for anyone to care about addressing this bug. Of the few people that I've found suffering from this anomaly, none have found a fix.
But the good news is that I have found a workaround that accomplishes getting a quicktime file out properly that does work for me. I avoid the Adobe Media Encoder completely.
Step 1: Go to File > Export > Movie, and under Settings > General choose QuickTime, under Video > Compressor choose H.264, then Uncompressed Audio. I have not experimented with other settings, but believe that most of them will do just fine.
If you examine the quicktime file you've just exported, you'll see it works just swell; i.e. no white frames at the end of the movie and the sound syncs up perfectly. Okay, sounds great---but there's no way to limit the data rate using this method, which means we're stuck with a ridiculously large file.
The solution is to load the Quicktime file that you've just exported into Quicktime Pro, and now export it using data rate compression / sound compression options to suit your tastes. Bingo!
The other workaround that I have heard from some is to export your movie (again, avoiding the Adobe Media Encoder, instead using File > Export > Movie) as an Uncompressed AVI, and then compress with QT pro as before. This method didn't work for me, something about not having the proper codec on my system to read the AVI file that was exported, which makes absolutely zero sense but I couldn't find the right codec anywhere, even after identifying it with some super-duper codec identification utility. Go figure!
So, you'll have to get QT Pro ($30 I think) to use this workaround, but it does work, and that's what counts. I have no idea if there's a QT Pro clone or similar program available out there. Compression/decompression and all that jazz is way beyond me and I'm just happy to be able to get my file finally out there in working condition.
The only other bit of information I might share with you is that I tried searching the Internet at great length to try and solve this issue, but on the rare occasion I did find someone suffering this problem they were as confounded and frustrated as I was, and no one had a real solution. I continued to search with different search terms and tripped over the clues to this solution when searching for "white frame problem" in relation to Premiere. I even believe that if you search the Abobe forums you may find some posts about it, so if you're inclined to learn more about it, I suggest concentrating your searches with terms that refer to the white frame problem/issue, instead of the terms I used for so long, such as "Premiere Audio Sync Quicktime" and the endless permutations thereof.
But I'll bet this workaround works for you. Let me know, and if you'd like me to try it on one of your exports on my computer I'd be happy to give it a go.
I have often wondered if upgrading to CS4 would solve this problem. Are you using CS3 like me? If I could be sure CS4 made this issue vanish I would jump on it, but there just isn't enough information out there to know for sure. I'm inclined to think not.
Please do let me know if this solution works for you, or if you dig up any new information.
Thanks!
