Combine audio from one video file with video from another I would like to combine high-resolution video in English with a foreign-language audio track from a low-resolution version of the same movie.

What is good software (for Windows 7) to combine audio from one video file with video (same video content) from another?

Ideally, it would also automatically correct for time offset based on the video content (frame similarity).
IF you have Win7, Movie Maker will do it.

If not, almost every video editing software where you can have more than 1 clip will do it.
If you thinking about doing some more stuff, you could use Hitfilm or Davinci Resolve.
