Strange thing when recording audio
I recorded a live concert using Vegas 6. After 2 0r 3 minutes into the recording a series of vertical lines appeared in the timeline, moving from left to right, and looked like it was erasing the recording. When I saw this, I freaked out and stopped recording in order the check. Nothing was erased but lost a little bit of the recording.
What are those lines moving in the timeline? I never saw this in the toutorials.
