I have an MP4 video that contains two audio streams, one English, one Japanese. When I play the video in VLC, it plays in English, but when I import it into Vegas for editing, I only get the Japanese. How do I switch to the English language for the video so that my final product is in English?
You can use a program such as tsMuxer to re-multiplex the streams minus the one you don't need. This is a very quick and lossless operation. You can also use the program to assemble multiple audio streams into files for playing. Though I don't do multiple languages, I frequently render .ac3 and .wav audio versions of audio tracks.
Or you can try this:
Right click on the video on the t/l, select 'Properties...', select the 'Media' tab and look for 'Stream:'. Pull down to see if there are two audio streams and if so, select the English one.

Unfortunately there was only one take to choose from, but I did use Virtual Dub to extract the correct stream, imported it into Vegas, and away I went. Thanks everybody.
