Hi, I made my movie editing in different project because of my computer. Now I want to make one project all of the parts. I imported all projects, open a new sequence completely the same features with the others. I copied from the parts and pasted the main sequence which I just opened. All of the parts contains synchronized audio channels. But when I paste them to another sequence; they are being out of sync. Also I'm getting the problem in the video.

 

My footages are 23,976 FPS

I activated the "show audio time units" all the time. 

 

Thanks all

    We're gonna need some more info.  Please tell us your system specs: OS version, Premiere version, amount of RAM, Hardware specs including graphics card and your source properties and your sequence settings.  By any chance were any of your sources from a smart phone or a screen recording?  If so, the issue may be variable frame rates.  Unfortunately Premiere can have issues with vfr and the symptoms are impossible to predict and sometimes to repeat.  I also don't understand why your computer made you edit your piece in different projects... might help to explain that.

    I'm using Windows 10 and the last Premiere which is 14.7. 

    Intel i7 2.50GHz to 3.50GHz CPU
    8 GB RAM

    Nvidia GTX 860M 2GB

    I shooted the movie with Black Magic Pocket 4K and the format is braw 2.6K 23,976FPS. 

    Sounds are rocorded with Zoom H5 48000 wav and with Zoom H1 41000 Hz wav. 

    My shooting spects all the time were the same. 

     

    The movie is abotu approximately 2 hours and my computer is not very strong. Because of this I decided the make my edit with parts. But the problem is that when I slide the synced items together. There were a bug again. Zoom sounds are going to out of sync all the time. There is no problem with the camera sound. Here is the video

    although it doesn't always happen, the mismatch of sampling rates may be the issue.  resample the 41k audio from the zoom to 48k either just exporting from premiere or use adobe media encoder.   You should be able to just unlink the 41k audio and then relink to the 48k audio without issues...
