Two iMovie questions/locking in new audio & split screen
I have a full screen interview subject I've positioned to the right side of the screen. I am trying to place a colored box on the left side of screen, then put copy on top of it.
I've also recorded the audio for the interview on a separate digital recorder. I imported the new audio and have sync'd it fine under the video.
Here are my two questions.
1. The newly imported audio track is separate from the video. The original camera audio is part of the video itself. How do I get rid of the original audio (from the camera) and lock the new audio to the video so I can edit without dealing with two separate elements (separate video and audio)?
2. I have created a colored box out of a still shot and just set it to repeat for the amount of time of the interview video. I planned on using the split screen effect to insert the box and employ the mask area to split the screen like I want. But I can't drag the box footage over the original to start the process. Must the box be an actual video too? Or can I use the repeated still shot as video and do the same thing? Or is there an even easier way of putting a box where I want it?
If anyone has an answer for my dilemma, I would appreciate your suggestions.
Thank you,
