Audio shorter than video after import

[VinoVino]

Hello Community,

Thanks in advance for your help and any tipps you may have for me.

I have a .mp4 file with variable frame rate that runs fine on Quicktime and Vlc. After importing it to premiere and embedding it in a sequence (no matter what fps i set it to) the whole thing gets out of sync and the audio drifts. It seems like, the audio is being compressed into a smaller time frame, while the video stays the same. To make this more clear: The .mp4 is a podcast episode, where the speaker says "goodbye" on the waveform 7 minutes before the video ends???? I've experienced similar before, but usually its the video that is shorter than audio, so I really don't know what to do at this point. 

Things I've already tried:

- exporting it on different codecs and fps through Media Encoder

- Handbrake CFR,  FFmpeg CFR, other editing application

- premiere on windows & versions of Premiere

- screen recording it with OBS and import it again

The overall solution must be simple, because I can't wrap my head around how I still have the same problem after trying all these things, and especially the screen-recording. If you have any idea, please let me know 🙂

Thank you very much!

Have you tried Shutter Encoder?

Thanks for advice. Sadly it didn't work. Audio and Video seem to be in sync now, but there is parts, especially towards the end, where the audio cuts out. Seems like Shutterencoder tried to fill the blanks, but its not pretty.
