  Beginner questions about SDI and Embedded Audio

  Posted by Cameron Hamill on February 15, 2013 at 4:26 am

  Hi Members,

  Does SDI output Video track with embedded Audio sync lock the streams together?

  What I mean is for example from the SDI output of an analog to SDI converter box with audio embedding.

  What I’m intending to do is go from

  SDI output of a converter box using SDI embedded audio

  PCI Express Video capture card with an SDI input.

  All I’m trying to determine is if the Audio and Video SDI stream are nicely “Syn Locked” together. For example like Genlock and those sorts of stream timing locks.

  Also how does a Video file with embedded Audio appear on a PC? What I mean is let’s say I analyse an embedded audio AVI file in Media Info Pro. Will it show a separate track for audio? Or will the audio be hidden somewhat in the Video track?

  Sorry about these questions but I really don’t know a great deal about Video files with embedded audio.
