This feature would be game changing for tutorial video workflows where you are generating an AI voiceover to describe something you are teaching people to do on screen for software or apps. Most of the labor for this type of edit comes from trying to sync up the screencapture with the voiceover. If you allow for 0.5x playback of the audio while the screencapture is being recorded into that exact spot in the script, then people will have plenty of time to think about what they need to screen shot as they are listening to the voiceover, then after when it plays back in 1x it will be perfectly aligned. You can also have a panel for notes that could pop up to remind someone of what actions they need to do in the screen capture to align with the script.
