Audio skips out of sync in several places when the export of the first pro

I have a short, 15 minute, turned to 23.976 FPS.  When I export to load in yet somehow audio jumps not synchronized to several different places.  The weird part is that in all cases there are 2 people in the scene and that a single audio out of sync breaks people.

I went through all the audio files in the sequence in Premiere Pro (CC) and the audio fits perfectly even though I play in first.

I checked and double checked settings FPS in first and still, as well as other parameters such as the video and audio format audio sample rate, etc., and everything is consistent.

I'm exported from Premiere pro using the "Multimédia" option and choose MPEG2-DVD, NTSC, 720 x 480, progressive quality of 23.976 FPS, 100, CBR, target 9.00Mbps, with audio PCM, 48 Khz, stereo, 16-bit output.

Source sequence is 1920 x 1080 (1.0), 23.976 FPS, progressive, 48000 Hz, stereo.

I also used Media Encoder on the same sequence to create an MP4 file and that seems to come out perfectly synchronized throughout.   So, I'll try using media encoder to create a .iso file, if possible.

I'm new to this, all the words of wisdom or of things to check would be greatly appreciated.  Thanks, Bobw

Voice out of sync with the lips.  I look for "bilabials" (P, B and M) in the speech, then make sure that the sound correctly synchronizes with the lips.

I guess we can do exactly the same with notes on an instrument if it was of expert musicians.

In any case, I turn on the "show time audio units" and then carefully align the appropriate sound with the position of the pack language appropriate lip. Often it's 'zoom' on the frame and audio tracks and the cleaning back and forth several times.

OK, but let's go back to my problem.  That, it turns off does not exist.  I treat so badly that I had to remove the camera and audio sound recorder and sometimes contract between the two during a audio jack.

AND, I actually had audio out of sync by about 3 images in three different places in my sequence, in one place.   And Yes, I looked at dozens of times and convinced myself that it couldn't be my work because I had "checked" so many times.

This was caused by a drawing of lots of last minute "tweaking" and "assume" that the settings I made did not affect the video tracks & audio following.  (HINT: it is almost always if you don't take extreme care and seems sometimes even when you do.)

AND I also had a "nested" sequence I had absolute fits for audio, synchronize perfectly on.

BECAUSE...   I had 'nested' video but I have NO audio with her nest.

.... The "Lesson Learned" here is: "If your export ends with audio out of sync quit"guess"that it is impossible because of your Premiere Pro sequence is wacked"

  • Razor tool Causes audio go Out of Sync

    Hello

    New Premiere Pro and video editing in general. I have an hour long video (.mp4) that I recorded with my Sony Xperia phone. I have been using the razor tool to cut and remove things I want, but it seems that it causes the audio go out of sync. I rechecked and the audio is certainly synchronized before starting to edit the video.

    Any ideas?

    Thank you

    It would be good to check if it is the CFR or video VFR, as more phones record video as variable rate, but may record audio as a constant. MediaInfo is good at that...

    Media Info: https://mediaarea.net/en/MediaInfo

    If you "drop" your file on that and look in the tree on the video stream, it will tell you if it is a constant or variable framerate. If variable, use:

    Handbrake download page: https://handbrake.fr/downloads.php

    To change the file to rate constant so PrPro can run better.

  • PSE video and audio go out of sync on finished product

    A very strange problem has developed.  I have a PRE project that plays perfectly into the program itself, but when I exit the project start audio and video in sync but go not synced to the first place where the audio and video clips are spliced.  To be precise, I have a file mp4 audio (.m4a) synchronized with a .mov file.  At the first break, where I spliced m4a, m4a and .mov to .mov, the project is in phase when I play in the video window of PRE.  But when I have the project output, video and audio go out of sync at the first break.  Other facts:

    • PC, 8 GB of RAM, W7, all installed updates.
    • By using the same file .prel about a month ago, it worked well.  (I tried to do a DVD extra of this project, when the problem came.) The only thing related to the video that changed on my machine was a new version of Studio of GoPro.  Just in case, I uninstalled from my computer and the problem of PRE is still there.  Could GoPro have left something it's messing things up?
    • In this case independent of the output - DVD, mp4 format, etc.
    • If I insert an empty picture at the junction stay video/audio synchronized until the next splice point, when he goes back out of sync.
    • It happened first in PRE9, but I also PRE13 (who reads the PRE9 files) and the problem happening there too, in the same way.

    I am completely puzzled, especially because this same project file perfectly synchronized DVD in the past produced.  Any suggestions will be appreciated.

    R.H.L.

    Thanks for the clarification of your question.

    Complexion all the case is if this problem is limited to a single specific project file.

    Here's what I read since you wrote...

    You say that your audio synchronized to export this file in a project is present for Premiere Elements 9.0/9.0.1 and elements 13/13.1 first.

    These programs do not seem to share/use the same built in programming of the export. And, further, you say that there is this audio desynchronization if burn disk or export the file to one of these versions at this time. Is this correct?

    Even if the problem is not manifest prior to export, which has been described above point to the project file. Have you changed anything in the project settings or export settings in this file of project for good time / wrong time - courses of transitions, component files software plug-in, flow? And you say that look very detailed to the timeline, the content of this one project has revealed no change before and now after? You write

    Would such a program have changed or are damaged?

    From what I just wrote, could the project file has been corrupted, but...

    If you want to look at this as a corruption of program, then you will need to take uninstall, cleaning, reinstall to 9.0/9.0.1 and 13 to dismiss this idea and replace any missing files of exporting program. But, once again, we are dealing with a single project or all your projects with this problem.

    Please consider.

    Thank you.

  • Audio video out of sync once imported into Encore CS6

    Hi all

    I am having some problems with Encore CS6 on my iMac with OS X 10.9.5.

    I'm burning a few videos I captured off the coast of the VHS using Elgato Video Capture. He outouts as .mp4 files

    The videos play fine on the outside, but as soon as I import them into even the audio becomes out of sync. I burned a lot of VHS to DVD and for some reason that the problem appears to be new.  It out of sync in the timeline, listen to excerpts and once burned.

    I even tried using Adobe media encoder to convert the .mp4 to MPEG-2 outside again and the audio is always out of sync. I even tried to cut a bit of the audio to the front because it seems to be just a little bit slower, and it worked for the first 5 minutes, then he again not synchronized.

    Does anyone have an idea as to whats going on? Or has experienced this problem?

    Thank you

    Angela

    And you can see here that my proposal was wrong. This is a variable rate. You need convert this file in constant cadence. I suspect that John may have a link to a converter. There are many more threads about that in the Premiere Pro forum.

  • Help!  Audio goes out of sync after export.

    OK, people. I need your help. I have a looming deadline of THIS FRIDAY to put this.

    I have a multicam editing over a show that runs 1 hour 20 minutes. It renders perfectly in the timeline panel, all the video and audio perfectly synced. Looks and sounds exactly like what I need.

    When I export the video in form file H.264, audio not get synchronized with the video of 13 frames! But that's not all... It doesn't go to the complete audio track. There are about 50 minutes in the middle of the video where the audio goes out of sync. The audio at the beginning and end of the video is aligned perfectly in sync. It is just the central part which is twisted.

    What should I do?

    This has never happened before, and I have worked extensively with multicam in first Pro CC before that. Never been a problem. I tried to uninstall and reinstall the first and also remove all media cache files, but still no dice.  I also tried to copy the clips in a new sequence in the same project, copying the clips into a new sequence in a NEW project, the nesting of the sequence... nothing works.

    My configuration:

    MacBook Pro retina (Rev A)

    First Pro CC (latest version)

    Panasonic GH3 images in 1080 p 24 p AVCHD timeline

    3 cameras & 1 audio file to WAV in Multicam

    Any help would be greatly appreciated!

    OK, I figured out how to fix it:

    1. In first Pro CC, choose SEQUENCE > DELETE RENDER FILES.
    2. Try to export the movie again.

    It worked! I exported the same sequence, and it took a lot of time to do a new rendering of the audio files, but when it was finished export audio and video are in sync. I don't know what caused it, but this fix, so I hope anyone else having this problem can save a lot of time in reading this.

    See you soon!

  • Audio & video out of sync

    Hello, I'm new to elements of Prime Minister, and I'd appreciate any help you have

    I imported a movie from my iPad using Adobe elements Organizer to my MacBook Pro 13 (end 2013) running OS 10.10.3. When I first see items 13.1, the audio and video are out of sync at the end of the film. It's the same thing when I publish the movie and view it on QuickTime. I tried to make the film before publishing, and it made no difference.

    However, if I find the original film that was imported using Organizer with the end of the film QuickTime is in phase.

    The file that was originally imported to my computer is H.264, AAC. I don't know how to tell the quality of the sound or the quality & settings for video and audio when it was imported to the elements of the Prime Minister.

    Anyone know what is the problem and how to fix it?

    Thank you

    What happens if you import your video of the iPad in first elements 13/13.1 editor first, not the elements Organizer 13.1 first.

    For now, I will assume that the iPad gives you a 1080 p 30 video. Please import 1080 p 30 video in the elements first 13/13.1 using the project preset

    When you play the video in the workspace Expert chronology, is the audio not synchronized with the video? There is no colored line or the line orange on this video content when you reading this?

    iPad with an image record generally rather constant rate variable. Premiere Elements does not fare well with variable cadence. The symptoms are out of sync audio cannot be importing the video at all. The response was to hold the iPad video free HandBrake to get a version of H.264.mp4 with a constant rate and not variable. Then take you this H.264.mp4 in Premiere Elements with Premiere Elements' add media/files and folders.

    Variable image is probably at the heart of your question, but I want to just make sure that your choice to transfer the video to the program and the project preset do not force the issue.

    Please review and consider. For any question or need more information, feel free to ask.

    Thank you.

    Add on... When you import files in Premiere Elements, a copy of the file gets automatically places in the elements Organizer. Advantage to place the file in the organizer elements and import from there in the first element Editor. To discuss if indicated.

  • Audio got out of sync somehow...

    Hi all

    I worked on a piece of footage for a few hours now, a master clip editing down to about 20 subclips, and everything was fine until a few minutes ago. The sound is completely out of sync and even out of order. It is not a matter of seconds fast or slow; the audio is jumping at a completely different time to the main element. I don't know why this happened, and I can't find a way around it.

    The main element plays precisely outside the first 5.5 in QuickTime, VLC and Windows Media Player. I tried to copy and rename the master clip and the replacement of the damaged file inside the first with the file named differently, but that does no good. I opened an auto save the way until this issue has been raised and which is messed up also. I rebooted first and all that... nothing helps. I even made on a small clamp to see if she makes very good, always messed up.

    This problem seems to affect only the subclips of this master file in particular, the other master files and their sub respective clips work very well... And I don't remember with certainty what I did right before this happened. I think I've been playing with the opacity of a subclip or something... This happened once before on a small project, but I have spent a lot of time on this one and I wouldn't lose everything.

    Any ideas on what I can do to save the clips? If there is a way to export the sub clip info and place it inside a new project or something... I do not know... It's the 20th video I edited on this hardware with the only occurrence of this nature happening before.

    Great, thank you. OK, let's try this:

    2. Open MPEG StreamClip and go to window > Preferences. Check "Flow of Fix with data breaks" and (although not entirely necessary for this particular difficulty) "preserve the GOPs to In/Out. Click OK.
    3. Load MP4 in MPEG StreamClip misbehavior (file > open files).
    4. Go to editing > Timecode break trouble; I don't know that it's necessarily the problem (or solution) but it does not hurt anything.
    5. Go to file > save as and choose a name and a destination for the file. Let the type of the value MP4 and click Save. This will copy the data streams of the original file - no encoding again that happens - and package it in a MP4 container.

    At this point, import the new MP4 in your Premiere Pro project and let me know if it worked. If so, you can select the original main item, right-click and select replace footage; Choose the new file and your changes will be kept, but the file will be replaced by the work file.

    What codec is used in this avi (as it isn't a regular avi of a camera) and if the framerate is variable, you need to convert to constant framerate before importing it in first.

    Converter for example Handbrake.

    Bit rate may be too high. Don't forget that CS3 is pretty old.

  • Audio track out of sync after importation of raw at first

    English:
    Hi there I have the following in first pro cc problem:
    I record Let's Play videos via Nvidea-Shadowplay in 1080p/60fps/30.000 Kbps
    I checked the equipment in VLC Player and all is well.
    Now, I do drag and drop the file into Adobe first CC and the audio seems to be out of sync.
    This is different. Sometimes the Audio seems to be beheind, and in other cases, it's too early.

    It is a serious problem for me, because it leads to a lot of post production audio tewaking to solve this problem.

    I have no idea how to solve this problem, because the raw material I recorded works perfectly, but the file is big
    to put on youtube, ofc.

    DAS führt zu viel Zeitaufwand beim Nachbearbeiten.

    Wenn ich das video dann Raus ist make're immer noch asynchronous.

    What you run is image variable rate (VFR) video.  ShadowPlay and any other application that uses nVidia's hardware h.264 encoders will produce VFR MP4 files.  Premiere Pro does not support the VFR vids very well at all; It is designed to handle the constant rate (CFR).

    To resolve this problem, you'll want to transcode your MP4 files using something like Handbrake on CFR versions.  I've never used Handbrake for this, but I know that others here to great success.  Search for phrases like 'VFR' and 'variable frame rate' and you should find a lot of results.

    I solved this by using the ffmpeg command line application, you can search and download from various locations.

    ffmpeg-i - hide_banner - 1 - crf 19 vsync - r 59.94 - vcodec libx264-preset copy - acodec ultrafast g 50

    If you prefer to use a GUI, then check brake hand or other tools.
