Rendering causes a clip to go out of sync

I can't figure this one out. I'm working with DVCPro HD 720p b-roll in an HDV 1080i60 sequence. The main interview is HDV, hence the sequence matches that. Most of the b-roll is fine, but there is one clip that, when rendered, goes way out of sync. Before it's rendered, it plays fine and it's perfectly in sync. I fixed it this time by just exporting the clip in question as Mjpeg A and re-importing it, but I'd like to know why this is happening in the first place.
Any ideas?

Aaron I have a similar problem. In my case the footage from one tape when played in FCP appears out of sync with the audo. the original file played in QT is absolutely fine.
When this footage is used in a sequence however, whatever you add into the timeline (audio is not used so I am only using the video track) looks okay in the sequence, but as soon as you render it or even review in the canvas the video is moved. it is not the same footage as scene in the sequence.
i am on mini-dv tapes PAL. FC 6.01
I tried exporting using qt to some different formats. An mp4 remains in sync however only if i convert it to a lesser quality.
the only difference that i can see between fcp footage that works and doesnt is the data rate of the 3.5mb/sec vs 3.6mb/sec besides that i can see no difference.
did you ever find out the cause of your problem?
thanks

Since downloading OS X Yosemite I have been having issues with Netflix. Video slows down which causes the audio to go out of sync. Netflix plays ok on ipad which makes me think it's the software which is the issue. Has anyone else had this issue?

Try this:
Go to System Preferences - Bluetooth. Delete the keyboard from the list of devices by pressing the "-" button. Take the batteries out of the keyboard and reinsert them. In Bluetooth Preferences press the '+" button to add the new device. If the keyboard begins to pair, click the word "pair" and type in the passcode. Press return. The keyboard is now paired.
If the mouse is not pairing, try this: shut down the computer completely, unplug any USB mice, then turn off the power to the bluetooth mouse. ONce the computer starts up again, wait for the pop-up looking for a mouse. Turn on the power to the bluetooth mouse. It should work normally now.

Clips from Project bin to source monitor causing video output to go out of sync(CS6 and CC)

Any footage I double-click or drag from the Project window to the Source monitor causes my video output to go out of sync. When I put the clips in the timeline, video goes back in sync and I'm able to view video output. My monitors are connected to a Blackmagic Intensity Shuttle Thunderbolt(9.7.5) via component and HDMI. Is this normal behavior in Premiere or is there a setting to enable this? No issues doing this in FCP7(clips from Project window to Canvas).
Can someone with an I/O from AJA, Matrox, or Blackmagic please test this out for me. Thanks...

Hi Joe,
How do you have your audio setup? Try the following.
- Set your OS system sound to Built-in or Line out audio
- Select Blackmagic for both Video and Audio in Preferences> Playback
- Select System Default Input/Output from Preferences> Audio Hardware
Hope this helps,

When I use media manager to upres clip audio goes out of sync

I captured a clip and put it in DVNTSC 48kHz timeline at OfflineRT NTSC (Photo JPEG) then used the media manager to create a new sequence at full DV NTSC 48kHz res. I choose "Create offline", "set sequences to DV NTSC 48 kHz", and check all the boxes. I save a new project, open the new timeline and recapture the clip. The video looks great--it recaptures in full DVNTSC 48kHz res. But the audio is out of sync (by about 28 frames it looks like). What am I doing wrong? (This is the first time I'm trying this offline-then-online-process.) thanks.

Try exporting the iMovie project as a single full quality dv format quicktime file.
I use iMovie6 HD and this is my usual procedure that works well.
Make the movie in iMovie, will involve many separate clips. When finished, export (share) as a single full quality dv format quick time file. When I have an hours worth of smaller projects, I create a new iMovie project and import all of the quicktime .dv files for each separate short project. I add chapter markers in this project, then share with iDVD. I then burn an hours worth of stuff at best quality and distribute to family and friends.
iDVD seems to work better with iMovie source that has fewer clips.
BTW: Are you having problems with standard def or hi def iMovie source. Another part of my procedure is that I take the raw tapes and download the entire thing into one iMovie project. I don't edit or change the footage at all, just want to archive to DVD for posterity. In this case, I want to share the iMovie project with iDVD directly. This has worked OK for standard def projects, but my first hi def project (1080i) that I tried, the sound was out of sync. To fix this, I had to create a regular DV widescreen iMovie project, and drag all the clips into it from the HD project. It took over an hour for my humble mac mini to convert the files, but I was then able to share with iDVD and the finished DVD worked ok.
Hope this helps.

After Effects rendering the video with the audio out of sync

so, the thing is, i did the animation on flash, exported it, put it on after to edit audio and what not, everything looks fine, previews are good, so, lets render!... every time i render the final video have the audio out of sync, specially the audio that is already on the first video. the video its originally on 12 fps, if i change the interpretation to 24fps, everything get worse. any help?

ok, both Flash and After effect are CS6, i have a Lenovo Ideapad, can handle 64 bits
first i exported the video on .MOV from Flash CS6, without any problems
Then i finished the edition on After Effects, everything look good.
i have tried to render it on MOV, AVI, MP4 and the audio for the video that was exported from flash always get out of sync. i dont really move anything else

Clip audio is out of sync with video

After analyzing the clip the code tells the tale. The audio is "shorter by 1 1/2 seconds yet the time line doesn't reflect it. I want to fix the problem but the tool I found requires the clip (red rectangular box with the +/- info.) to option/click on to be given the re-sync tool action. Other solutions require complicated solutions. My question is "What happened to cause this sync problem and how can I avoid it in the future. ie: no evidence of =/- red boxes to show that there is a problem even thought it clear when you look at the video clip ?

We are missing fundamental information:
What codec does your source footage use?
What is the audio sampling rate on the source footage?
What are the Sequence settings in FCP and does what you see there differ in any way to the properties of the source footage?
Version of Mac OS X, FCP and QuickTime?
Also; if you have a 2 x 3 GHz Dual-Core Intel Xeon Mac OS X 10.6.6, it's a Mac Pro, not a G5.

CC 7.2: out of sync indicator on merged clips - possible to hide / set?

With the CC 7.2 update, existing projects have turned into a mess of out-of-sync indicators on merged clips (DSLR video with separate audio sources, synced using PluralEyes). In previous versions, Premiere apparently accepted, or ignored, merged clips for sync indicator purposes, but now it seems to have decided to assume that the "synced" state is when audio and video start at the exact same time. Since the audio source is external, clicking the indicator to bring "into sync" obviously has the opposite effect.
For now, we've been reduced to the workaround of using the Ctrl-F12 command console and setting debug option TL.Don'tDrawSyncIndicators to True, which gets rid of the visual clutter. Of course, that means that sync indicators everywhere are gone, including where they would have been useful.
I'm sure all of this works fine with newly synchronized merged clips, or maybe even clips previously merged by Premiere, but that's not going to work for 27 hours of synced footage and a 90-minute rough edit...
So, am I missing something very obvious here? Is there some way to have merged clips be ignored by Premiere, as they used to be? Or even better, to "set" a merged clip as being synced and actually registering sync shifts in respect of the correctly synced position?

Strike those last comments of mine, I think I've figured out the fundamental issue and it seems to be a clear bug. It's actually completely unrelated to PluralEyes, but here's how I figured it out:
PluralEyes creates linked, but not merged, synced clips on a timeline. To add those synced clips to a bin, you will need create merged clips. Problem is, Premiere will always consider a merged clip from such a clip to be "out of sync" if there was any trimmed audio preceding the start of the video. And trimming audio preceding video is precisely what PluralEyes does by default.
It turns out the sync indicator problem does not occur:
- If video started rolling before audio (PluralEyes never automatically trims video); or
- If the trimmed audio is manually restored using the selection tool on the timeline prior to creating the merged clip.
Basically, trimming an audio clip prior to using it as part of a merged clip, causes Premiere to interpret the merged clip as having been "created out of sync". It's as if it's interpreting the trimming of the audio as a shift in the start of the audio. This is obviously not right, and it didn't happen prior to CC 7.2
The issue can be reproduced at will by taking any random video and audio clip, regardless of sync, shortening the audio clip at the beginning and then creating a merged clip. Adding the new merged clip to a timeline will lead to it appearing to be "out of sync".
There's a relatively simple workaround on new projects: undo (or disable, not sure if this is possible) the automatic trimming of audio clips in PluralEyes and don't trim audio prior to creating merged clips. Unfortunately, this is no solution for the current project, especially given the many limitations Premiere still has when dealing with merged clips.

Capturing directly from camera causes audio to go out-of-sync

I'm capturing directly from Canon XHA1 camera into FCP7 on my Macbook Pro (onto an external hard drive) via Firewire. I'm also recording to tape in the camera at the same time.
This works fine -- until I stop & start the tape while recording. This causes the audio to go out-of-sync with the video on the Macbook captured file. (I just let the computer keep capturing, while stopping & starting the tape in the camera.)
Is there a setting in FCP7 to alleviate this problem?

YOur not alone.
I use a Sony Z5, and usually doesnt have a issue, but noticed recently that we are having some sync issues out of the blue.
We connect to a MacBookPro via firewire and capture live in FCP.
We have since changed cameras that records onto SD cards, and havent had a issue since. But just wanted to let you know, your not on your own!

Picture and audio out of sync on DVCPRO50 clips

I digitized some 29.97 fps/16-bit audio DVCPRO50 footage in FCP6 at DVCPRO50 setting. The captured quicktime clip plays back fine in the quicktime player, but when I drop the clip into a DVCPRO50 project timeline, the video plays back faster than the audio. The longer the clip plays, the more the sync discrepency. I digitized several clips, and I noticed that the data rate is different for each clip, varying between 6.0 and 6.2 MB/sec. One clip with a data rate of 7.0 MB/sec plays back fine, same settings, same everything. What made this clip different, and why does it work when the others, all the same except the data rate, don't? More importantly, is there some way to change it so it does work without having to re-capture my footage?

How long are the clips that are out of sync? In my experience there is a bug that appears from time to time that throws DVCPRO 50 footage out of sync if you capture it in chunks longer than 10 minutes. The only solution I have found is to go back in a break up the capture so that clips are no longer than 10 minutes a piece. Look in the browser under the audio column and instead of seeing 48khz you will probably see something like 47.982345 khz or similar. If that's the case then you have to re-digitize. Make sure you are using log and capture instead of capture now, and try not to run any other programs on the mac while you capture.

Help! New to FCE - captured audio out of sync

I just switched from a PC to a Macbook Pro. I had been using Sony Vegas on the PC and have switched to FCE since Vegas isn't available on Mac. I tried capturing my first footage last night into FCE. The audio on the tape was 32kHz, so I went to EasySetup and selected the DV-NTSC 32kHz setting. After capturing about an hour, it gave me a message saying analyzing or rendering audio for about 5-10 minutes. When that was done, I tried to play the clip, bit the video and audio were about 1 sec out of sync (video was ahead by 28 frames). In this case, I was able to unlink the audio/video and manually re-sync them, but can anyone tell me what might have caused them to be captured out of sync, and what to do to ensure that it won't happen again?
Thanks!
Erich

Thanks, I'll give that a try later today and see if that solves the problem.
One other question, does video imported through iMovie need to be rendered in FCE? I tried capturing some footage in iMovie (with the same setup) and it played fine in iMovie (no sync problems) and when I imported it into FCE, it played fine in the viewer, but when I dropped it into the sequence timeline and tried to play it there, I couldn't hear the audio, just a beeping sound, and there was a red bar over the sequence to indicate that it needed rendering.

Some audio out of sync in after Export

Can using the built in Audio tools like Loudness, or adjusting the sound levels in the waveform cause the audio to go out of sync?
I'd say not...but that is what seems to be happening.
I have a 2hr 30 projet for a DVD.
All individual clips captured on Canon 5d 3 at 48khz 25fps
Project is 48khz 25fp, as set automatically when the clips were first dropped on the timeline
One particular group of 3 clips, seems to randomly and suddenly loose sync in the middle, sometimes at the start, some times in the centre, then often it comes back at the end.
Of the whole 2 hr 30 project only this bit is giving issues, all other clips have been edited in the same way, and are similar lengths,some longer, some shorter, all stay in sync. Max clip length about 8 minutes
In the timeline the audio stays perfectly in sync
I have re made the sequence of three clips , totalling 24 minutes long, probably 6 times now. and each time after adjusting the audio levels the exported audio has variable sync,
Also re imported the footage and tried again
No added audio tracks, just a single compound clip containing three complete clips, with the ends trimmed
Audio has not bee detached from the video.
All I am doing is adjusting the audio levels,
Hum On
Noise reduction to about 2%
Loudness On :
Amount 20%
Uniformity 15%
First noticed this yesterday on a DVD burnt using "Send To Compressor" Create DVD
Also happens using the in built Share, to DVD, ot share To master File
Output settings are also 48khz and 25fps
If I do an export of the clip With no audio corrections, it is fine. But as son as I try and adjust the audio levels, it goes out of sync.
I'd half suspected I had somehow dragged the audio in the timeline, when adjusting the levels, but no. Go back and play the clip in the timeline and it is perfect. But Share that compound by dropping in to a New project, export as master and Playback in QT and the audio goes out of sync after I have done a levels correction. Un-corrected ( for level only ) audio stays in sync.

A/V out-of-sync issue for FCP captures

I've read many of the out-of-sync posts on this board, most of which seem to indicate that the problem is usually caused by either dropped frames, bad timecode breaks, edit errors, or disunity between FCP capture and sequence settings, compared with audio sample rates for the underlying files.
My files, shot on my Panasonic AG-DVX100A in 24pa mode, result in perfect (except for the anamorphic screen size - see my next post!) Quicktime movie files, in perfect sync. It's only when I create clips from those files in FCP that the video and audio go out of sync. And the out-of-sync drifts; that is, the further you go in the clip, the more out of sync the sound and the video gets.
My camera is always set to the 24pa mode, which, by default, records only in the non-drop-frame mode, regardless of any other camera settings I may have selected. The audio settings in my camera (and in the resulting underlying QT files that are created when I capture in FCP) are 16-bit integer and 48.000 khz, as they are in both my FCP sequence presets and capture presets, so I don't think it's an issue of conflicting sample rates. My device control presets are for Firewire NTSC NDF (non dropped frame).
Given the above information, does anyone have any idea what else I might be doing wrong? I've already shot hundreds of hours of footage last year that worked fine. I don't know what I changed to cause this out-of-sync problem now, but I'm going bald tearing out my hair trying to figure it out.
Thanks in advance for your help!

The dvd recorder was in the loop when the sync issue showed up. the dvd was in sync but the live stream, next in line, was out of sync. I have returned to using the older machine with xp. (the lap top is running vista) The older machine is a desktop which requires more space on the production table and time to set up.

Imported MJPEG from Game Capture Software Suddenly Out of Sync

First, I should point out that I am new to Adobe products. I'm entirely self-taught with Premiere, and I know there are a lot of things that I don't fully understand yet. However, my methods were working fine until a couple weeks ago. Furthermore, I searched through the forums and couldn't find any issues quite like mine. A few were similar, but none helped with my issue. I'm sorry if there is something really simple that I'm overlooking here, but I would greatly appreciate any help.
For quite a few months I used PlayClaw 5 to capture video game content and then import it to Adobe Premiere Pro CS6 to edit it and piece together gaming compilations. It worked without a hitch until about two weeks ago when the audio in the imported file stopped syncing correctly with the video. I'm not doing anything different that I know of, although PlayClaw 5 did have a recent update. I'm not sure what information would be useful in a situation like this, but I can provide the following:
My usual Premiere set-up:
Capture format is HDV
Then I usually set my sequence presets to HDV 1080p30
From there, I have Premiere maximized and drag a video file from a folder to the project window. I wait until it indicates that the file has been imported completely, then I go about hacking the video and audio (which is usually mixed together from PlayClaw 5) and creating my own videos.
You can see in this video, the sound is synced perfectly - but a couple weeks later, I made this video, and the audio is off by just a bit, but it's noticable. Now all my imported videos have out-of-sync audio.
I can also provide the type of encoding that PlayClaw 5 uses for the videos:
Video Compression: MJPEG (quality at 95 with the option of YUV411 compression, was on for the second video link)
Capture frame rate: 29.970
Compression threads: 2
Smooth frame flow enabled
draw cursor enabled
Convert to sterio enabled
Mix audio in one track enabled
Container: AVI
Unfortunately, it doesn't give any other information about the audio.
Again, I'm sorry if this is just my lack of experience with video editing. Also, I apologize if this isn't a typical Premiere problem.
Thank you in advance for your time.
Edit:
I realized that I never actually included a question...
Is there something I'm doing wrong to cause the audio to go out of sync all of a sudden? And is there an easy fix for this issue?

My audio gets out of sync with my video after capturing from Sony XDCAM

Everything was fine. I captured content from my Sony XDCAM, created pieces, no problem. Imported a .mov from my older FCP (5.1.4). FCP told me I needed to change my settings in order to use the .mov with my current timeline. I said OK, fine. Now, when I capture from my XDCAM some of the audio is in sync but it goes out fairly quickly. Any Ideas? I noticed in the bin the clips which are out of sync have a different data rate then the good ones. HELP!

Sound effect is out of sync

Hey all,
I'm trialing Premiere CS6.
I have my sequence, about 1:20 with many video clips and tons of sound clips. I exported the sequnce to a pro res 1920x1080 24p, uncompressed audio.
The entire thing is pretty much perfect, as far as I can tell, except for ONE sound clip which I know is not in the right spot. It is a slow tension crescendo that has been speed up (with pitch mainatained) to fit within my video clips. When viewing the exported file, the audio clip reaches it's tension climax about 1 second or so before it should. In the timeline, it lines up perfectly.
As far as I can tell, this is the only sound clip that is out of sync, which is really weird.
Anyone know what could be happening?
Thanks
Specs:
MBP C2D 5.53 8 gb ram

My bad, I was always under the impression that H264 was a type of quicktime format and thought you meant to export to a different uncompressed format.
I'll give it a shot, tried to adjust a few things to see if that makes any difference
