Subclip has extra audio in timeline, out of sync but no sign in timeline

Ok, so, when I created a sublip and checked it in the viewer it looked and sounded perfectly in sync. Once I put it into the timeline and play it in the canvas it looks like the clip accrues an extra second or two of audio and therefore it's out of sync. However the clips don't show this. The red box that indicates how out of synch the audio and video are doesn't appear on the clips in the timeline. Why is this, how can I fix this? Thanks.

Well, I was looking in the browser at my media, which is DV and was imported using an HVX200, and I noticed that all of the tapes I imported save for one have a video rate of 24 fps, data rate of 2.9 MB per sec, and an audio rate of 48048 Hz and under field dominance it says 'None'. The exception is one that for some reason has a video rate of 29.97 fps, 3.6 MB/sec, audio rate of 48.0 KHz and under field dominance it says 'Lower (Even)'. This exception is the only material where when I sub-clip from it and put it into the timeline the material doesn't go out of sync. All of the others do go out of sync. The solution may be very simple and I don't know if I gave enough information to help you supply an answer but as you probably guessed I'm very much a beginner at this so any help would be appreciated. Thanks for the response!
Oh and as for how I've been sub-clipping I've just been going through the sources, putting in and out points and overwriting or inserting.

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.

Change of Video Frame One Sample Out of Sync with Correct Point on Timeline

Change of Video Frame One Sample Out of Sync with Correct Point on Timeline.
It has been found on the author's PC that, in Audition 3 in Multitrack View, a video file displayed in the video window will change its frame one sample later than it should do with respect to the correct point on the timeline. This has led to extra work having to be done by the author, as detailed later.
To demonstrate this issue:
Create a new multitrack session. Enable the Time and Video windows. Enable only 'Snap to Frames'.
Using an external program, render a two-frame video clip at 25fps. Let the first frame contain the letter 'A', and the second frame contain the letter 'B'. Making sure that the Display Time Format is set appropriately, in this case at 'SMPTE 25 fps (EBU)', lock this clip on the multitrack timeline, ensuring that the clip starts at time 00:00:00:00.
Create a mono audio clip of silence at 48kHz 32-bit that is two frames long. Lock it on an audio track, ensuring that the clip starts at time 00:00:00:00.
Place the cursor at time 00:00:00:01 and create a cue marker at this point by pressing F8.
Zoom into the timeline so that approximately twenty samples are visible, with the cursor lying on the cue marker in the middle of the screen. The Time window should display 00:00:00:01. The Video window should display the letter 'A'.
Move the cursor back in time (leftwards) by one sample. The Time window should change its display to 00:00:00:00, whilst the Video window should still show the letter 'A'.
Move the cursor forwards in time (rightwards) by one sample, so that it overlays the cue marker again. The Time window should change its display back to 00:00:00:01, whilst the Video window remains showing the letter 'A'.
Move the cursor forwards in time (rightwards) by one more sample. The Time window's display should remain at 00:00:00:01, but the Video window should now display the letter 'B'.
As can be seen from the above steps, the video's change of frame content occurs incorrectly one sample later than it should; the change of video frame content should occur simultaneously with the change of the frame number displayed in the Time window, which is at the point that the cue marker has been placed.
The practical effect of this issue is that it has caused the author a huge amount of extra work on an 89-minute long soundtrack-for-video timeline. There were over 1100 changes of shot which the author wished to mark by placing cue markers at the beginning of every shot. This should have been a quite simple process of enabling 'Snap to Frames', stepping through the video, and laying cue markers down by pressing F8 when the shot was seen to change.
Because currently the Video window (referencing the cursor laying over a cue marker
i that has been placed on the timeline using the 'Snap to Frames' option
) will actually display the end moments of the previous frame rather than the beginning moments of the current frame, laying down a cue marker when the shot is seen to change will actually place that marker at the beginning moments of the second frame of the new shot, not at the beginning moments of the first frame of the new shot, i.e. the cue marker placed will be one frame later in time than it should be. If it is wished for the cue marker to, as best it can, represent the beginning moments of the first frame of the new shot, it has to be manually repositioned so that it is at least a sample later in time than the time at which the shot has actually changed, in order for the Video window to correctly display the content.
The author had to manually reposition all 1100+ cue markers.
Ideally, the Video window should display a change of video frame in synchronization with the change of the frame display in the Time window, which occurs at the position of the 'Snap to Frames' point.

MP4 clips out of sync when dropping onto my timeline and I can't fix it.

I'm trying to drop some mp4 clips onto my timeline in CS6 Premier Pro. The problem is the audio keeps going out of sync. It plays fine elsewhere but for some reason doesn't sync up properly in the timeline and I can't fix it. It looks like the video is slower than the audio/ the audio is quicker. When the clip is on the timeline it has a green line above it where as everything that is in sync has a yellow line. All clips have been imported from my internal drive. I'm using a Macbook Pro 2.4GHz dual-core Intel Core i5. Does anyone know how to fix this?

What is the source of your clips, and do they possibly use a Variable Frame Rate instead of a Constant Frame Rate?

Audio And Video out of sync in Final Cut, but not in quicktime

I heave searched the forums to no end to find the solution to this issue, unfortunatley, I have not solved the problem.
I am using Final Cut 4.5 on a G4 running OSX 10.3.4. This system has worked perfectly for years with no problems. Neither the system, hardware, or software has ever been changed on this machine. Suddenly last week, despite perfect sync while previewing the capture, the Audio and Video were of sync in Final Cut, but when checked in quicktime, there were no problems. That is how I eventually figured out this was a final cut problem.
By out of sync, I don't mean it is by a specific number of frames that can be adjusted and then everything is fine, the sync seems to drift so that if you edit the audio to be in sync in one part of the video, it won't be at the end. Also, it is out of sync from the first frame played, not a gradual drift.
This is definitely not an issue of frame rates or final cut settings as will be evident by the steps I took below to find the source of this problem.
This is what I did to attempt to fix the problem:
- Check drives using disc utility and repair permissions
- Remove Final Cut Preferences using Apple guidelines
- Switch hard drives
- Delete Final Cut and reinstall newer version of final cut (since the capture files played fine on Final Cut 5.1 on another machine)
- reinstall entire OSX 10.3.9, wiping the hard drive and reinstalling Final Cut 5.1
- switch ram slots, and even replace ram with different sticks from another G4 machine
None of these solutions worked. Is there some hardware problem with my G4 that is suddenly causing Final Cut to play audio and video out of sync?
Hope you can help, otherwise this otherwise great G4 is going in the dumpster!
Thanks

For what it's worth, I'm having what looks to be the same problem. Driving me insane. Here's what's going on-
Editing in FCP 6.0.2
QT was just updated to 7.3.1 the other day (hmm)
On an MacBookPro machine, OS 10.5.1
Software updater says everything's up to date of course.
DV-NTSC 24p (23.98) Advanced Pulldown Removal (footage was shot at 24PA on a DVX100b)
In Quicktime, the file previews fine, everything's in sync, everyone's happy. In FCP, the video and audio are wildly out of sync. I did a test inside of quicktime and sliced out a small portion of the media clip and did a "save as" and this small slice played in sync in FCP. However, this did not work for the entire clip. Clip is weighing in at 5.58GB for a 32 minute run.
I'm trying to multicam 2 tapes together and manually syncing these up is proving to be difficult at best. When anyone gets any ideas/leads/patches, let us know.

Audio and Video out of Sync in Encore 2.0

Here's my issue:
I opened a project in Encore 2.0 that was an Encore 1.5 project. I have one timeline with a 2 hour movie and the AC3 audio file that goes with it. Encore 1.5 played the audio and video in sync from the timeline and burned discs with the audio in sync. The video is an MPEG2 file encoded at a 3.1 constant bit rate.
In Encore 2.0, when I play the timeline, the audio becomes progressively out of sync as it plays. Within the first few minutes it's maybe a frame or 2 off. By the end of the film it is about 18 seconds off (audio is playing ahead of the video).
Is this a result of Encore 2.0 conforming the audio file? If so, how am I (or anyone) supposed to attain sync between video and audio in Encore 2.0?
I have Encore 1.5 and 2.0 both installed on the same machine. As a test, I opened the project in 1.5 and played it, everything was fine. I closed Encore 1.5 and opened the project in Encore 2.0, and the audio is out of sync.
Any comments, ideas or suggestions?
Mike

Joe,
I tried creating a project with the original WAV file and it's corresponding video and found that the audio and video were still out of sync. I did a little more testing and discovered that the audio is actually being played correctly, it's the video that is not being played correctly. Here's what I did:
I opened the WAV file version of the audio file in Premiere Pro and noted where a hammer hit in the video occurs (01;40;30;28). I then opened Encore 2.0 and imported the video and AC3 version of the WAV file, placed them in a timeline and the audio's hammer hit is right where it's supposed to be (01;40;30;28), but the video's hammer hit occurs at 01;40;43;18.
Next I went into Encore 1.5 and brought in the AC3 audio and video files and placed them on a timeline. I went to 01;40;30;28 in the timeline and the audio and video were both at the frame they should be at that timecode.
Seeing how the video appears to be playing incorrectly, here's some info on my video files:
I have 4 versions of the same film in varying encode rates with the same start and end timecodes. All four files were encoded on a Sonic DVD Creator authoring station using hardware to encode. The files are encoded at the following rates: 2.9 constant bit rate, 3.1 constant bit rate, 3.4 variable bit rate and 4.0 variable bit rate. They are each NTSC with drop frame timecode. All four files play correctly in Encore 1.5 but incorrectly in Encore 2.0.
This almost seems like a drop frame/non-drop frame issue. Do you have any ideas?
Mike

Audio and video out of sync on short recordings

I've scanned the discussions and see that alot of posters are experiencing
the same problem I'm having which is recording quicktime movies
and getting audio and video out of sync.
In most of those posts the responses seem to be that the problem gets
bad if you're making a long recording. I'm experiencing that, but...
...I'm also having the same problem on really short recordings...less than a
minute. I've coming video and audio out of my cable box, into a SONY DSR-11 VCR, then firewire out of the deck into the computer, recording the movies with Quicktime 7.1.6.
I know it's coming out of the cable box and then out of the SONY deck via firewire in sync because when I log and capture through Final Cut Pro, audio and video are in sync in preview and playback. I don't want to use Final Cut Pro to capture the movies because I want to end up with MPEG4, and I'd have to go through an extra conversion process out of FCP.
Any thoughts on why even short recordings through Quicktime are out of sync?
Thanks.

I'm having similar problems transferring VHS video to Quicktime. Another problem I'm having is when I transfer a VHS video to iMovie and then export the video to H.264 format, I have similar sync problems, even though the iMovie seems perfectly in sync.
I'm going to try to transfer several alternative video formats (video from my cable DVR, Video from live TV, and video from a digital mini cassette to try and figure out whether the VHS format is the culprit. Will keep you posted.

Flash player audio and vidio out of sync

flash player audio and vidio out of sync. audio lags 2 seconds behind vidio. this is a flash player or silverlighr problem. please help.

A lot of times it's in the video itself. A great example of it is "Tarantula", a 1955 "B" horror movie, on YouTube. About twenty minutes inti the film the audio suddenly drops about eight seconds behind the video. This happens when a video converter (software) requires more processor or RAM than the system converting it has available.
If it only happens with certain videos, it' what I've described above and there's really nothing that can be done about it.
If it happens with ALL videos you're watching, try right clicking, choosing "Settings", and under the far left tab, "Enable hardware acceleration"

Audio slowly drifts out of sync with video

I have a long continuous video clip (.MP4) that has an audio sample rate of 48 kHz. Separately, I have an audio clip (.mp3) for that take that was recorded at 44.1 kHz.
I created a sequence in Premiere with the .MP4 making sure the sequence's audio sample rate was set to 48. I brought the .mp3 into Audition where I used Edit > Convert Sample Type to change it to 48 kHz.
Back in Premiere, I dragged the converted .mp3 into the sequence and the audio still drifted out of sync toward the end of the clip.
Am I missing a step? How can I make sure the audio and video are in sync throughout rather than just in the beginning?

Two independent record devices will not stay perfectly synchronous over a long period of time unless locked via timecode or a sync cable.
A solution is to scroll to the end of the clips and adjust the speed of the mp3 file (making it run slightly faster or slower) until the end of the camera audio and mp3 audio coincide.

When I watch tv shows in Front Row that I've bought off iTunes the audio gradually falls out of sync with the video. It does not happen with other files that I have converted into mp4s. Any ideas for fixing this? It's a huge bummer...

I too have the same problem. The audio drop out of sync in about 5 sec in not uncommon for the audio to be 30+ sec behind video. Apple needs to fix this!!!!!!!!!!!!!!!! its a joke, my iphone is all messed up after the last update as well. at one time not to long ago apple products and software were top rated, not so much any more, more and more problems are showing up and apple is unwilling or unalbe to fix the many issues. Apple needs to fix the audio sync problem, it not the computer hardware or other software it ITUNES!!!!, there is no workaround other then hitting pause and hitting pause and hitting pause to temp fix the problem.

Audio and video out of sync

I have captured tapes from my DVD camera and am in the process of editing clips and have noticed that the video and the audio are slightly out of sync.
How can I correct this?

I don't think it was a "DVD" camera!
Often sync problems are caused by recording the audio at a different setting than the Easy Setup capture preset.
The normal DV-PAL or NTSC Easy Setup is for 16bit audio.
If you recorded at 12 bit you need the "DV-PAL (or NTSC) 32KHz" Easy Setup.

Audio is/goes out of sync

Hi guys,
Brand new user to Premiere Pro CS 5.5
I took some clips off my Galaxy Nexus that I shot the other day and wanted to cut them into a short video so I imported them into Premiere.
When I play them in Premiere the audio appears to be in sync at the very beginning of the video but as it progresses through it seems to be worse and worse out of sync as it goes along. Even in a short 1 minute clip.
When I play these raw video files in something like XBMC or the standard Windows 8 media player, or even just on my phone there don't see to be any problems with the audio/video being out of sync what so ever.
I tested this out with several random clips recorded on my phone and it seems ALL of them are doing this in Premiere no matter the duration of the video.
Why is this happening and how do I prevent/correct it?
Thank you

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!

Audio several seconds out of sync with live video stream.

I did a live stream last week using 282,482,832,1500Kbps streams. What would cause the audio to get out of sync with the live video stream? I'm trying to determine if it was bandwidth related, cpu/memory issue on the FMIS 4.5 server, or an issue with encoding PC exceeding it's limits?
Thanks,
Dave

Which device are you using? Are audio and video coming from the same device or different devices?
Is it a USB device? Try changing the device and see if there is any difference. Changing bitrates will not affect audio-video sync.
