For the pros: Different length in audio- and file of the same stream

[sebastian]

Hi guys,

when downloading and merging the video files of be-at.tv (e.g. hxxp://www.be-at.tv/brands/wmc/surfcomber/waveform-with-victor-calderone-guests/ida-engberg.go ), the video and audio file (which are splitted) do have different lengths.

In my shown example, the downloaded mp3 is 01:28:36, but the video is 01:28:49! Also the video slider at the website itself shows 2nd length.

So how can I get the video and audio in sync? And what is the master lenght?

I guess this is a question for the pros. ;-)

Thanks in advance!
