Have you thought about integrating AI script generation into your manual scripting tool?
I played around a bit with the new AI scripts, and they are quite impressive. There are large segments where they are practically indistinguishable from manual scripts. But there are segments where they struggle (such as transitions between scenes)
I think there is an opportunity here to reduce the time manual scripts take by 5-10x.
You may consider using your model to fill in the high confidence segments, and leave the low confidence ones for manual scripting.
Does your AI model output a confidence score in addition to value that you could use as a cutoff? If not, can you potentially train a parallel classifier using the same feature values to predict confidence level?
