Audio and Video Sync

Hey Gang,
Reaching the point of frustration with a relatively simple Imovie project I'm trying to create. I've imported 2 separate groups of .mov files created by a utility that extracted the video from a DVD (DVDxDV). In both cases, the problems began when I selected multiple files to import. The first file would come in okay but by the time the last one was imported the audio was completely out of sync and played the same section of audio for all the video. It seemed I could overcome this by importing the files one at a time until I found that even after doing this and having the files import correctly, over time the audio and video would get out of sync within imovie.
i have all the imports in a particular event and begin to drag segments to my new project. If i close I movie and come back to it later, the audio and video in the project starts to become out of sync. It then usually starts to happen when I preview the video in the event window as well. Importing requires so much time that deleting entire events and projects and starting over is driving me bananas.
Has anyone experienced this before or have any ideas as to what's going on?
Imovie 08 build 7.1.2 (577)
macbook with lots of free drive space.
no updates are available for imovie.
the problem is occurring within imovie before I export to anything.
Help!

I am having the same problem. I am trying to use different video clips for talks. Once I have more than one clip in the video library, it plays audio from the first clip for all video??? Would love to figure this out.

Having trouble Audio and Video Syncing on iTune

Having trouble Audio and Video Syncing on iTune anyone know how to repair?

Here are two suggestions:
If everything is pretty much in sync until 17 minutes in, do a re sync every ten minutes. This should ensure that, even if the sync drifts by a few frames over 10 mins, the video will not seem distinctly out of sync at any time.
Another approach would be to do an overall re-sync in QuickTime Pro (which I believe is part of the FCP package).
You would need to use QTPro to trim,the video file to remove any surplus seconds of material at the beginning and end. Then open the audio file in QT Pro and trim that if necessary. It may be a slightly more complicated to do this at the beginning because, if the audio does not come in immediately, you'll need to make sure that you have the right amount of silence at the start of the file to match the video before the audio begins. This should leave you with video and audio files of the same length.
Then, in the drop menus of your QT, select and copy the audio track. Switching to the QT video file, in the drop down menus, click on add track.
Hope one or other of these May be some help to you.

TIMECODES are important for audio and video sync issues

Hello, just wanted to pass on what I learned so that others can avoid the trouble that I've had to go through. Perhaps this may help someone who is stuck on the launch pad. :)
BOTTOM LINE: Info for the beginner. Audio and video not in sync in Premiere Pro CS3 V3.2.0
PROBLEM: Capture works great it seems. When I go to the folder that contains the captured file and view in Windows Media Player audio and video are in sync. BUT when viewing the video asset in the source and program monitors, the audio and video are not in sync.
SOLUTION:
Before capturing a tape make certain the following is checked:
(1) Edit->Preferences->Capture->Use device control timecode
(2) Edit->Preferences->Device Control->Options->Timecode Format
(3) Project->Project Settings->General->Video->Display format
As for the devices timecode choose something other than Auto Detect. Then match the project timecode with what was chosen during capture. The projects display format could of course be set to frames.
I searched everywhere for audio and video sync issues in google, adobe forums, F1 help, and hv20.com and everyone was talking about:
(1) Presets: 1080p30 vs. 1080i30 (60i).
(2) brakes in the tape where timecode for the audio and video get misaligned during capture.
But choosing the correct hardware settings and timecodes to solve audio and video sync issues never popped up.
MY HARDWARE: Canon HV30, HDV

>Audio and video not in sync in Premiere Pro CS3 V3.2.0
Must be an HDV only issue because my synch is always perfect.

Audio and Video syncing issues

I have a video file where the audio and video file are normal when I play the clip in Quicktime. When I import the file into an FCP project and drag it into the timeline, the audio and video are no longer synced. My sequence setting is ProRes422 as is my video clip. The only difference I can see is that my clip is 24 bit integer and the sequence is 32 bit floating point. Although, this is my 50th project capturing old BetacamSP tapes and all my projects say this and I haven't had a problem until this particular file and not afterwards. Any thoughts?

There you go then ... make sure you monitor audio and video by the same path ie both via the Kona card or both on the Mac ... or use the Playback Offset to compensate for the delay between the Canvas window and the Kona output.
From the manual:
To set the frame offset between the computer display and the external video and audio outputs
Choose Final Cut Pro > System Settings.
Click the Playback Control tab.
Enter a number of frames in the Frame Offset number field.
Frame offset can be any whole number between 0 and 30. The default value is 4. For example, if a video monitor connected to your DV camcorder shows your program four frames later than your computer display, a frame offset of 4 will synchronize the two.
Note: Depending on your external monitor configuration, you may need to experiment with frame offset values to synchronize the external monitor and the computer display.
Click OK.
Play your video in the Canvas or Viewer and compare the video offset between your external monitor and your computer display.
If the computer display and external monitor are still not synchronized, repeat steps 1 through 5 using different frame offset values until the display and monitor are in sync.

Logic 9 Audio and Video sync at beginning timecode, but not in the middle of playback.

Hey Guys,
I'm working on a Trailer for a feature length, and my video playback is pretty screwy.
I've double checked the video to be 23.976 framrat and set my project to that framrate, and I've done what I normally do with bitrate and sample rate. But currently my audio and video will not sync together when I start playback in the middle of my project.
Playback works fine in the start of the project, and everything looks and sounds great. But as I'm writing and edtiting further on in the project all the audio gets out of sync. If I start the project from the beginning, then all of the MIDI for the whole piece registers as synced, and the project sounds and looks great the whole way through. The problem comes from starting playback anywhere in the middle of the project.
I'm working with a .mov file (1:45 minutes); three .AAC audio files, and plenty of thrid-party plug-ins. 10.7.5 Mac OS X, 2.2 GHz i7 core, and 4GB m
of memory.
Any thoughts?
Thank you!

Thanks guys for the input.
I am using an Aurora 16 via firewire
I did change my buffer settings and that seemed to fix it but now I am at 128. I moved over to the aurora because I preferred the extra headroom. I guess I should have stuck with the apogee.
Tonight was the first time I had the opportunity to do a full tracking session with 9. I have been doing quiet a bit of mastering with no issues. Quiet a few issues. Everything from logic quitting to it just locking up. So far.....a pretty bad experience. I wonder if it could be Snow Leopard.......

How to fix problems between audio and video sync?

Hello, I have this old camera DSR 200P and I'm trying to import to my final cut pro x. The importation success well but at the end the syncro between audio and video doesn't work. How can I fix it?
It's possible my mac doesn't accept this kind of camera or should I change any options of final cut?
Thank you

I use to edit footage for a client that was recorded on a DSR-250 (successor of the DSR-200) and every time, every single time, the audio sampling rate would not match my Sequence settings of 48khz, 16bit. The sampling rate of the captured video was always off by a slight amount. It might be 47999.9 one time and 48000.1 the next time ... but it was never at 48000 as it should have been. I chalked it up to Sony using cheap synthesized crystals (frequency generator) to control the rate.
Anyway, the fix was to export the captured clip using QuickTime Pro with the export's audio settings to 48khz, 16 bit.

Audio and video sync problem

Hi,
I have a problem with audio and video synchronization. I'm using Merge class to merge video and audio tracks. But audio track can be shorter then whole video track (for example video length: 2 min., audio length 1 min.). When I merge them everything is OK. After that I'd like to concatenate more tracks (generated from merge) into one final video file. For this purpose I'm using Concat class.
But here is the problem, after I concatenate all these tracks then the result video is OK but audio is synchronized right after the previous audio track ended. (If I have video1- 2min. audio1 - 1min., video2 - 2min., audio2 - 30 seconds, then second audio2 starts in 1,30 min right after the first audio track. But I want to start it when the second video2 starts.) Do you have any ideas??

Thanks for help in advance.

Ok thanks.
I tried to implement PullBufferDataSource and everything went ok, the audio .wav file was generated, but when I run that file, the length is 0 and not the lenght I wanted (40.00). Where can be a problem?
Here is the code I wrote/changed:
TimeDataSource tds = new TimeDataSource(40.00);
Processor p;
try {
    System.err.println("- create processor for the image datasource ...");
    p = Manager.createProcessor(tds);
} catch (Exception e) {
    System.err.println("Yikes! Cannot create a processor from the data source.");
    return false;
}I set content type to WAVE:
// Set the output content descriptor to QuickTime.
p.setContentDescriptor(new ContentDescriptor(FileTypeDescriptor.WAVE));I use DataSource as the next:
    class TimeDataSource extends PullBufferDataSource {
                 private double duration;
                 TimeSourceStream streams[];

                  this.duration = duration;
                  streams = new TimeSourceStream[1];
              streams[0] = new TimeSourceStream(40);

Audio and video sync problem using itunes player

When I play a movie using itunes it starts out okay but after a few minutes the audio and the video are no longer in sync. Anyone have a solution for this problem

HDMI Audio through the HDMI out port to one of the TV HDMI in port.
Tried on Windows 7 Pro 32bit and Windows 8.1 Pro 64bit.
Tried with the integrated ALC889A audio device enabled and disabled (It seems that the video card drives the HDMI audio device, because it still appears in Windows even if I disable the Audio device in BIOS).
Latest iTunes and drivers installed.
Apple, any suggestions? I'm not having a great customer experience after buying a pair of HD movies in iTunes.

Premiere Pro CC 2014 QuickTime Audio and Video Syncing problem

Hi everyone,
I am having and issue when I import QuickTime video into Premiere Pro CC 2014. I've just started doing some editing so I am very new to all of this. I recorded video in Photo Booth on my mac. I exported the file to a .mov file and imported it in to Premiere. When I play the file in premiere everything is fine up until halfway through the video. The video starts to play faster than the audio and everything is off. When I play the video in QuickTime everything is fine. I don't know if I did something wrong when I imported the file but I am hoping for some help. Thank you.

I would be willing to bet the video is recorded as VFR, variable frame rate ... in other words, it creates more frames per second when it needs to for keeping up with screen changes, and less when it doesn't see much changing on your screen. This saves bandwidth of course, BUT ... PrPro is not setup to work well with VFR footage, it really needs CFR, constant FR. So ... highly recommended if your capture program doesn't allow setting CFR is the free program "Handbrake", which you can google for. Use that to convert the footage to CFR, then import that into PrPro.

Audio and video sync problem Cs4

Hello!
For the latest 5-6 years i had the same problem.
Video and audio goes out of sync if I capture more then about 10 minutes. The same if I export more then about 10 minutes.
It doesen´t matter what camera I use.
We have 3 different ones
Sony Hvr-A1e, Trv950 E, Pdx 10p
It doesen´t matter what computer I use. Right now we use imac 2.8 Ghz Intel Core 2 Duo. I have tried with PC the same problem.
We always upgrade the Premiere program.
It doesen´t matter if I record Dv Sp or HDV. The same problem.
The process looks normaly like this.
Record in Dv SP Ns48k or HDV1080i
Sequence Presets
Dv PAL Widescreen 48khz
or
HDV 1080i25 (50i)
What makes it even more confusing is that sometimes we capture 30 min in premiere and then when you play it in VLC it is not out of sync but it is in premiere???
I have seen Threads about this but no solution.
Everything works fine if we record shortclips and export less then 10minutes but when we try with longer projects 30 minutes or longer it have NEVER worked. That is the most strange thing. If it works with short projects It can´t be my settings that are wrong or???
Sorry for my terrible English

Unfortunatly I can´t find this program for mac but maybe there are something similiar "out there".
Strange that Adobe can´t fix this???
Thank you anyway! :-)

Audio and video sync - could someone help me ?

Hello
I'm looking for a solution to synchronise imported audio with captured video on final cut pro, more precisely than at one frame...
For the moment I use soundtrack pro to do it, but it takes a lot of operations and time...
It would be very helpfull for me to be able to do it.
So, thanks for your replies and have a good day.

1) Open the audio clip in the Viewer
2) Move the Playhead to the In point, then press Command = (Command + equal sign) to zoom in as far as possible on the waveform
3) Press and hold the Shift key and use your mouse to position the playhead to a better point of sync with 1/100 of a frame accuracy
4) Mark In
5) Edit the clip into the Timeline

Major Audio and Video sync Problem

Hello World of FCP Users,
So heres my issue and I hoping you guys can help me out.
20 Years ago we recorded a play using an old VHS camera. We captured this footage into IMovie 09. The audio of this movie is awful and really hard to hear anything. Everything is too loud.
However, we did record the audio on a cassette deck with amazing sounding audio. The audio sample rate of this in FCP is 44.1 and the audio in imovie (which was later brought into FCP) is 48 khz. We can sync up the audio which looks great but once we play the video back in FCP, it starts off great but then slowly drifts out of sync.
We did however try to resample both audio tracks in Soundtrack Pro but still gave us the same result.
Any idea here?

The usual answer is to break up the video into segments that are short enough to hide the audio drifting out of sync or short enough to have a reasonable loss of sync, say, 15 frames or so. You are going to apply speed adjustments to the audio tracks to match the video tracks.
If your audio is out of sync at the end by, say 10 seconds, you've got break up the video into about 20 pieces and individually resync each. Unless you can tolerate what might be a noticeable pitch change and then you just adjust the whole clip.

My audio and video are in sync, but get out of sync as it goes along?

I recorded an audio file on Garageband and I am trying to line it up with a iMovie video. At first, the audio and video sync up perfectly, but as the video goes along, a delay starts to appear and grows bigger and bigger. Anybody has a solution?

MASMAS
The first thing that we need to know are the properties of what you are putting on the Timeline. What works in another software does not necessarily work in Premiere Elements. Each program has its own supported formats.
a. What is the file extension for this file? .MOV or .MP4?
b. Does the iPad describe it as 1080p or 720p?
c. If you open Premiere Elements 12 and go to Edit Menu/Project Settings/General, what do you see for Editing Mode, Timebase, Frame Size, and Pixel Aspect Ratio, even if those field appear to be grayed out.
Two immediate troubleshooting avenues are going to be in the direction of...
a. Project settings not set up to match the properties of the source from the iPad. Then we would start a new project and set the project setting manually before importing your video. Details for manually setting the project preset are in the following.
ATR Premiere Elements Troubleshooting: PE11: Accuracy of Automatic Project Preset (New Project Dialog) Setting
b. The iPad video being recorded with a variable frame rate instead of a constant one...the remedy then would probably be to take your video in a program like HandBrake to change the variable to a constant frame rate. And after that, import the corrected video into the Premiere Elements project which has the correct project preset (preferably set manual to assure the correct result).
Please see what you can put together in the way of video details, and we will sort this out.
Thanks.

New Project will not save, re-open with accurate or matching audio and video.

I filmed footage last week. Uploaded it into Premiere Elements and edited the footage in Elements, and saved my work as a project. I opened Elements this morning, and upon opening my saved project I was prompted by the program to locate the file. When I then selected the raw footage files, it loaded the project, but with audio and video out of order, not synced, etc.
How do I save my work as a stand-alone project file with the audio and video synced as I intended, in a format that I can load, share, re-open and work on without having to re-locate the raw video?
This seems to be a basic function of Video Editing software, so I hope it is something small I can adjust and move on from. Oh Also all the files, both project (.prel) and raw footage (.mov) are saved on the desktop of the computer i am using to run Premiere Elements.

brjames1
What version of Premiere Elements are you using and on what computer operating system is it running?
After you have created a project and it has been saved, you should be expected to be able to reopen the project with the
project as before the save/close (some discussion about rendered files remaining rendered, but essentially as written).
When they do not, we can invoke the damaged project syndrome.
The following is an Adobe document on that subject.
Troubleshoot a damaged project file | Adobe Premiere Elements
If you are getting "Where is the file....?" messages when re-opening a saved closed project, typical reasons
a. you have moved, deleted, or renamed files and folders that were imported into the project after the save close...when
you import media into a project, all you get are copies of the originals in the project. But the project needs to trace back
to the originals in the hard drive location where those originals were when first imported into the project.
b. if you store your source media on an external hard drive, the external hard drive may be malfunctioning and/or the
drive letter of the external drive changing for a variety of reasons. Does any of that apply to you.
Please review and consider, and then we can decide what next.
Thanks.
