I found a partial answer. It does look like you can select multiple camera angles (clips), but each must have been transcribed beforehand. See the following video for details:
The method I was hoping to use is quite similar to what the video shows:
- Transcribe clips
- Export transcript to text file
- Edit text file to remove bad takes
- Select transcribed clips and choose AI Tools-->Create new timeline using Intelliscript
My hope was that the result would be 2 video tracks (Talking head and screen cap) with the bad takes removed, which I could use as a rough cut. I could then dig into more detailed editing.
However, the Intelliscript-created timeline is so mangled it's unusable. It also seems to speed up some sections to account, I suppose, for mistimings between various clips? I'm not sure.
In the end, I suspect Intelliscript is an unworkable solution for my needs at this time.
