user20878: Does such a program exist whereby I can query a keyword in a database of all my transcript and audio content, and all instances/time-stamps will be displayed? The goal is to prevent my editors from having to do the manual search, as we need to create many trailers very quickly each week.

user19905: Convert all your transcriptions to subtitles (with timestamps) and save as one big plain text file, then just use ordinary search tools. This question more related to software for movies catalog.
But I think, you want not just keywords. You want "hot" places from your videos. I experimented a bit with automatic trailer creation:

https://files.catbox.moe/hu91ip.mp4 (same, but other song)
https://files.catbox.moe/mzhc7v.mp4 (funny bug: credits as scene)

There videos was produced in full automatic way, including scene selection, beat matching and re-timing. As you can see, this is very cool, but not perfect. So, I not finished this tool.
