Recently I was preparing video for my YC application [1]. I've used RecordOnce[2] and actually it worked pretty great - I've recorded my actions together with voice. It transcribed voice to text and then used text to voice again to render the video. For me, as a non-native speaker, this was really great. And I could edit voice description of my actions post-recording - worked like a breeze. It still rough around the edges, but nonetheless I highly recommend it (for reference - until now I've used Screen Flow for multiple years)
