I just released an open source tool that I needed for deterministic recording and cutting of App Store video previews for my iOS apps. I call it retake, because the commands & lingo are generally cinema inspired. The sets, scenes, and edits are defined in JSON and use anchor points relative to actions performed in the recorded takes. This allows a video to be rerecorded as your app changes and easily tweaked to get it just right. The tool is probably most helpful for indie devs.

Overall, this makes it pretty straightforward to record an iPhone and iPad App Store app preview video using one edit definition. Load up an agent, ask it to integrate Retake, describe the portions of the apo you want it to highlight, then let it run with it. You can control the environment used for the app (env vars, user defaults, and files on disk) to ensure consistently reproducible results.

Feel free to fork and go wild, or PRs are welcome upstream.
