Multi-Clip Scrub Sync Problem

So im editing an 18 multi cam music video... Each clip I didn't sync by time code, but I made a sync mark at each beginning track so I have a basic rough outline reference point. I marked in each clip so it syncs up to that sound marker... And then I multi clip all of them. They are all roughly in sync...
Now im scrubbing the first individual camera 1 so it could be perfectly in-sync with the main song.... Moments later,Camera 1 is all synced up...
Now I check lets say Camera 2 and its completely out of sync its like in the middle of the song, how did it catch up to that point when I didnt even touch/move any other cameras? What do I do?
Its like when I synced the first one clip everything else bounced way out of sync even though I didn't touch it...
I also tried less cameras like 15 and still did it...
Any idea? Help?
Thanks guys!

Well it was a 1 camera shoot project. I just organized each input to match my sound sync... but if i scrub to perfect the clips, the other clips some how go way out of sync, really strange.
Im running on the most up to date quicktime, FCP and OS system... But have a Duel G5 Tower.
What im doing is, Im not perfecting the multiclip file, just gonna cut it together then scrub it on the timeline when its all set in...

Sync problems when sending to soundtrack pro

I am currently having a problem with a mono track audio/video clip sliding out of sync when I send it to soundtrack pro as referenced file only with 10 sec handles. When I send the entire clip the sync problem doesn't occur.
I have used soundtrack pro before and never encountered this problem.
I'm on FCP 6.0.3.
Thanks.

Turns out the audio needed to be linked to the .motn sequence.

Sound bitrate not the same. Audio sync problem. Clip not segmenting.

Hi. I used FCP to edit various wedding videos. I have never had problems edditing my own videos in NTSC dv or hd. Somone asked me to edit their tapes wich have been recorded in PAL ( european) format. I don't know what amera or format they used but when i try to import them i keep getting the sound out of sync error. I checked and it seems that the sound is ok but would like to get rid of this error just to be sure. I am importing as dv-pal in fcp. any ideas as to how to find out the bitrate or sound type or how to get rid of this error? like i said in NTSC i don't have issues. Also in NTSC when i import a clip it segmets it to 1 clip per shot and for PAL it does not do that . It makes the whole tape one clip. Any sugestions? Thank you.

To check the audio sample rate easily in the browser just scroll the blue bar at the bottom of the browser. If you haven't rearranged the columns it should be around the middle somewhere.
Curious, is your audio out of sync in the viewer as well as the timeline/canvas? If it is in sync in the vieweruse Shanes multi-clip sequence trick to create a sequence with the correct settings. Control click on one of the clips, choose make multiclip sequence, then delete the extra muticlip sequence folder from the browser. As long as all of the imported clips have the same settings they will all fit nicely into this new sequence.
But... if the clips are out of sync in the viewer then you have a problem with the way they were captured.
You used the word import. Just to clarify, are you importing clips from a disk or hard drive that SOMEONE ELSE previoulsy captured? Or are you using the term import to describe capturing the footage into your computer from the source tapes yourself. Import and capture are two totally different things.
If you are importing data that someone else already captured and the audio is out of sync then you need to either recapture the tapes or get him to recapture them because they were no doubt captured with the wrong settings. If you are importing yourself, find out what camera they were shot with and get the settings.

Audio sync problem after scrubbing

I'm trying to piece together some clips from a TV series called Legend of the Seeker. I'm using Premiere CS4 4.0.1, Vista Ultimate 64-bit.
Placing the hour-long video in the Source Editor allows me to play the video fine from beginning to end, but if I start scrubbing through the file, the audio unsyncs itself immediately.
Here's a screenshot of the video in GSpot:

Setting IN and OUT points and then dragging a very small clip into the timeline has the same result.
Any ideas would be very appreciated.

You are actually pretty lucky to just have Audio sync problems, though I do not know why scrubbing would make any difference. With both Xvid and DivX one more often gets no Audio, or no Video.
Agree 100% on the 3rd party conversion, prior to Import into PrPro.

Frustrating audio sync problem with MJPG clips!

I make short films from our family trips, using the jpg:s and mjpg clips made with our Canon compact digital camera. This has worked fine (since PE 2). Now I often get a frustrating audio problem on SOME of the MJPG:s, SOMETIMES.
When I play the clip in PE7, after 0.5 - 1 sec the audio jumps back to start, before it continues to the end along with the video. This makes the audio out of sync with the video (lagging 0,5 – 1 seconds).
The only way to fix this is to separate the audio track from the video, cut the start of the audio (to where it jumps back to the start) and then move the audio track to make it in sync. Besides being a tedious way to do on all clips, the audio track is not possible to extend “in the other end”, so I have to cut the video at the end as well…
However, this is not happing on all MJPG clips but only on some.
Also, the clip looks fine in other programs, e.g. wmp or windows movie maker.
I have tried other MJPG decoders but that does not make any difference (so it’s obviously no problem with the video). The audio is PCM Audio 44100Hz, 706 kb/s mono.
Now, when I tried repairing the PE7 installation, updating DirectX, removing all caches in the project directory, rebooting, it worked! The clip I was testing was in sync!
But, the next day I noticed the sync problem again on a lot of other clips… I then thought I should try to force PE to reanalyze the video again, so I remove the cache-directories (did not help) and moved the project file to another directory (this did not help, but on the other hand, I didn’t see PE7 analyzing the video again, so maybe there is a cache somewhere else??)
I noticed (looking at properties on the clip in the preview window in PE7), that the original audio is 44100Hz mono, but PE7 converts it to 48000Hz mono. Don’t know if there is some problem there, but it should not be any difference on different clips from the same source… (and the “jump back” in audio is 0,5-1 seconds regardless of clip length, and not the 9% that the difference in frequency would suggest + the audio plays in “normal speed”).
I’ve run out of ideas!!
Please, does anybody have any constructive ideas or tips on what to try? Are there more caches to clear? Are there conflicts with another program, like wmp?
(I use PE 7.0 on a 4Gb, quadcore system running Windows Vista Home Premium 64 bit.)

Thanks, I suppose I can start batch-converting my mjpg movies before importing them inte PE7, if that would make this problem disappear. I'll try that (I have FormatFactory installed, but VirtualDub seems like a nice tool if that is better), although that would make the process a bit more long-winded...
Regarding GSPOT info on a file that works and one doesn't, there are typically no difference between them (except length and content, of course). In fact, as I mentioned above, the same movie did not work until I did some reinstalling, clearing caches etc. Then the same movie suddenly worked OK again.
I attach the GSPOT info on that file.
(I never had this problem on my older XP system that run PE2...).
I will try converting to see if the problem disappears.
Thanks!

Problem with multi-clip... viewing angles during playback

Hi everyone, this is my first post here.
I'm having trouble with my multi-clips. I create the clip with three clips, and set it up to view 4 angles at once. However, sometimes during play-back, the viewer will revert to a single view of whichever view is currently selected. How do I keep this from happening? I made sure it's set to "open", and still set on 4-up. I have no idea what's causing it.

Welcome to the forum,
My guess is you've allowed the multiclip to render (causes single frame viewing only)...
I'll usually...dbl-click multiclip in timeline, then set it for open with viewer window button, then single click in an empty space in the timeline.
So, try deleting renders and the second suggestion...see if that helps.
Further, I've set a keyboard shortcut for the 'open' function, so now all I have to do is dbl-click multiclip, hit the '/' key, then click in open space in timeline.
Hope that helps,
K

Multi-clip almost never works for me on the first attempt

Anybody know why when setting up a multi-clip, I can almost
never get it to work the first time I hit the timeline to start playing.
All my settings are correct, but either the viewer or timeline doesn't move on the first time try.
All I do is take my playhead back to the beginning of
timeline, hit play again, and usually it then starts working correctly. Sometimes I have better results if I hit the play in the Viewer instead of the Timeline, but it's not a consistent thing.
Again, I'm in open sync in Viewer and Canvas/Timeline, I'm in Unlimited RT, dynamic video quality and frame rate, multiclip activated there, turned off high quality scrubbing, ect.
I'm usually doing this with (3) short 3 minutes DV clips
on a mac book pro.
When I do get it going after the second, third or fourth attempt, I haven't changed any of the settings,...I've just confirmed that they were right to begin with.
Anybody else experience this and any ideas on how to get it to work correctly first time out?
Thanks.

so effectively it's on a different drive, sort of
But still using the same reader heads as your primary drive. So technically, it's still the same drive.
I just cut a 4 angle music video last week using my MacPro at work, and even with the source media on a FW800 G-Raid, I was still getting delayed playback and couldn't even view the 4-up display when playing back. So I moved the project to our XSAN, and with the fibre backbone there, bandwidth was definitely increased.
So the other variable in this problem is bandwidth as well as RAM. I know that a fibre based storage system isn't in everyone's budget, but I'd recommend trying out an eSATA based drive, given that I had trouble with 4 streams over FW800.

Multi-clip help!!!!

I have a project with 17 seperate multiclips. I first started making 1 multi-clip then editing it, then making the next and editing that and so on..... After making the 2nd multi-clip, when i try to edit it, the viewer locks up and wont let me change angles or between open and sync off. I get a message saying..
"Sequence error: Unable to add clip to sequence.
Possible media limits problem in clip or sequence."
Now this problem is solved by restarting FCP, but it persists after i edit one multi-clip??????? Will trashing preferences help???? Maybe I have some setting wrong???? Any help would be appreciated. Thank you.

If the problem goes away with a restart of FCP it does sound like trashing prefs could help. If it only happens on one certain multi-clip you might have to identify a bad clip that is in that multi-clip. But be aware FCP multi-clip/multi-cam is very powerful but very strange in its operation and behavior. You must research, read and do tutorials before expecting to operate without error.

FCP: AUDIO SYNC PROBLEM

i have audio sync problem -- of the finished product which didn't have that problem before. does anyone know how this could have happened? in my earlier posting, there was a warning window which i played around w/ and now i have an audio sync problem in my prior projects.
please help me.

The Reels, are indeed the 5 surround channels. I have a feature that is broken up into 8-10 minute sections. I did this because the composer was using a G3 at the time and couldn't handle the whole movie at once. They are 16bit 48khz aif files exported from ProTools. The biggest thing here, is that at one point everything was in sync. I am trashing the preference files now to see how that works.
It's not a playback issue as well. When i scrub one frame at a time, the sync has drifted off later in the clip. It's very strange.
In my previous post I said the one of the Reels was in sync. That was because I recreated it, by making a new project and copying the video from the timeline, and re-importing the 5 audio streams. It didn't work for any other reels though. it is still out of sync in the main project.
Trashing prefs did not work.
Also, I tried a lot of the things in that technical doc, but non of them worked including trashing prefs.
The real weird part is that the Audio file SAYS it is the same length of the video, but the audio ends later. It's in sync in the beginning but not at the end.

The project label now carries signal with yellow triangled exclamation “i tunes out of date”.
To solve the sync problem I’m following advice and detaching sound from all of the 100 or so short clips. This operation has been stalled by the spinning ball. Shut down restart has not helped.
The Project is mounted from Iomega and superspeed ext hd connected to imovie09 on macosx 10.5.8.
What to do to resume repairs to the audio sync problem and so successfully share for youtube upload?

Audio sync problem with videos imported from iPod Touch

I have an iPod Touch 4th Generation that I used to shoot video at a family birthday party. When I imported the footage into iMovie '11, the audio is not in sync with the video (video is about two seconds behind audio) and there is only the left channel of audio. I verified that the video on the iPod plays just fine--no audio sync problem, both left and right channels work. I just upgraded to iOS 5 on the iPod Touch. The iMac is running Snow Leopard 10.6.8.
As a workaround, I can import the video into iPhoto instead. When I play the video in iPhoto, there are no audio sync problems and both channels of audio can be heard. I have imported other iPod Touch videos successfully into iMovie '11 in the past few months, but this has been the first time these problems have occurred. Any help would be appreciated.

Premiere cannot handle clips with variable framerate.
Your converted clips need to have constant framerate.
Otherwise use a converter like Handbrake.

Strange audi sync problem & different, stranger video sync issu in sequence

I have two strange occurances with one particular set of media that was downloaded from the same original source mini-dv (recording in dvcam) tape. I have not found the same issue on any other footage.
1) when the media is imported into FCP, the audio is out of sync. it is slightly out at the beginning and then gets progressively worse.
2) when this footage is used in a sequence, the video that show in the sequence is not the same as the video that is exported when this sequence is exported as QT movie (or any other export option) Like the audio the video out of sync gets progressively worse.
- The original media is perfectly in sync looking at the digitized source ie: in Quicktime. There is no audio out of sync problem.
- the only difference I could see in the file was that this media is 3.5mb data rate whereas all the others are 3.6mb.
- other tapes from the same camera do not have a problem
- I do all my downloading from a firewire deck and not from the camera
- I upgraded from 6.0.1 to 6.0.4 (as did the QT 7.5 upgrade also) to see if that fixed the problem but to no avail.
Very perplexing. I managed to work around this problem in a sequence whos deadline was looming by manually slipping the footage in the sequence the required number of frames. This is where it also gets odd. I was able to do this by
- double click the clip in the sequence which then loaded that into the viewer.
- position the playhead at the beginning of the clip
- from the canvas select the go to position in master clip option which then loaded the masterclip into the viewer. the position in the masterclip was always the correct frame (ie the frame I expected to see as per my edit). The frame showing in the canvas was also the correct frame (but this would not be the case when exported)
- the next thing i did was to use the slip tool, as soon as i held the slip tool over the sequence clip, the frame in the canvas would be the wrong frame (the frame i would see when I exported).
- then i would just carefully slip the sequence clip back to the matching correct frame. So watching in the viewer, I would align the frame that showed in the viewer to the frame in the canvas.
When done the frame showing in my sequence would be a completely different frame but when exported, the frame that I expected to see would be the exported frame.
I could find no logic to the amount I needed to slip each time (I am sure there is logic but I couldnt figure out what that was). the clip at the end of the footage needed to be slipped -10:09, and this got progressively smaller to the clip at the beginning of footage needing to be slipped -:16
Hopefully that wasnt too confusing.

btw, i have tried recapturing the footage and i have offlined it, copied it to another location and onlined it in the new location to no avail. still have the sync and video in sequence issues.

Sync problems with outlook 2007 calender

I am new in this type of comms.
BUT: I have a Palm Tungsten T5; have Palm Desktop 6.2.2 with the update for Windows7.
I have a sync problem with outlook 2007 calender; contacts, ToDo, memos all ok.
HotSynLog says: there are multi-day repeating records. [i knew that they do not sync, hence i deleted them PRIOR to syncing]
I found the listed records BUT either on dif days and they are "no timed" ones! and NOT multi-days ones.
I deleted them anyway - did a re-sync. With no different result. Still listed - though deleted and now non-existent.
Error code: OLERR: 03-000F (0xaf604005) and others - if this means anything.
Post relates to: Palm TX

Hello,
I receive email on my device from two addresses: 1) @sprint.blackberry.net and 2) @charter.net. When I was having problems similar to those you are experiencing, I had these two addresses listed under Default Services - Calendar (CICAl) - Messaging (CMIME). These addresses were @sprint.blacberry.net and @charter.net. Once I followed the steps previously referenced, only one email address(@sprint.blackberry.net) appeared under the (CICAI) and (CMMIE) default setting. Reference to @charter.net was removed. My syncs have worked correctly since then; however, I only two way synce with the device and Outlooks. I also continue to get emails from both addresses without a problem.
If you don't mind giving up the Yahoo calendar, I would do the same. If you want to continue using the Yahoo calendar, I'm guessing that it must be selected in the Default Services - Calendar (CICAI) before performing a sync. Likewise for your @sprint.blackberry.net address; it also must be selected in the Default Services prior to performing a device to Outlook sync.
I hope this helps.

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.

Line Up Clips for a Multi-clip Edit

Hi I am editing a dance video, when it was recorded at the event a few of the camera people decided to pause after every song - this has made it a hassle to edit. I am trying to line up the clips to get them all in sync for a multi-clip. The only way I could think of to do this was give each camera angle a track and line them up that. I almost have them all lined up, but I have no idea how to make it back into one clip, since it is currently cut into tons of pieces. How do I combine them back into one clip? The closest I could find was Nesting, but that creates a sequence, and I can't make a Multi-clip out of sequences.
Each video track is a different angle, the screenshot I posted doesn't show all of the clips lined up, because I didn't get quite that far. How can I make this into a multi-clip
I just started using Final Cut about a week ago and I don't really know how it all works....yet.
Any help would be appreciated.
