I have a few movies in two versions:
- In good quality with English audio
- In bad quality with Polish audio.
I would like to get the Polish audio and add it to the video with better image quality. The problem is that these versions are of different speeds, and starts with a little shift. What software and method would be the best to align the audio with video? I can use OS X or Windows for this. It would be great if there was automated way to do this, but good manual way will also be great. I was thinking about using waveforms or similar video frames to align somehow.
