So I was editing a video interview for a client. Said client had a video intro/outro that he wanted me to add at the beginning and end of the video. I thought, "no prob." But as soon as I drop that intro/outro, the right side of the audio from the interview disappears. I tried panning right, and it just goes silent. I tried adding the intro as another track, still the rest of the interview is still left. As soon as I remove the intro, both sides of the audio are back. Soon as I put it back, BAM left side only.
How in the world does this happen, and how in the world can I prevent this from happening??
Any help would be greatly appreciated
