Hello.

I have a clip recorded with smartphone but something went wrong and I have the sound not in sync with the video.

What filters should I use to import this clip with Avisynth into VirtualDub?
I tried DGAVCIndex to create proper dga file but it returns errors.
I don't need to recompress the clip, I just need to shift audio.

Below is what AVInaptic says about it:
