◇ Could this help me?
Yes, with the install handled properly and expectations set low on the specifics. The underlying idea is real and checkable: a set of skills that turns assets you already have, a deck and a brand guide, into finished video is a genuine use of this tooling, and the creator is honest that it is slow rather than claiming it is instant. The better takeaway is the one she mentions in passing, publishing the same resource in a chat version, a workspace version, and a coding agent version, which is a thoughtful habit for anything shared with people working on different surfaces. General practice, with two caveats: the video is enthusiasm rather than instruction so there is nothing here to follow step by step, and a third-party skill repository is installed code that should be identified and reviewed before approval rather than trusted on a recommendation.
I want to generate video from assets I already have, specifically a presentation deck and a brand guide. Before installing anything, find the publicly published skill repositories that do this, and for each one tell me who publishes and maintains it, how widely it is used, what files and services the skills actually touch, and whether anything it does would send my material anywhere. Present that as findings and install nothing until I approve it. Then tell me what quality I should realistically expect from my specific assets, how long a single run takes, and what I would need to prepare differently to get a usable result on the first attempt.
