 I added captions to all my videos. Captions matter, obviously if you suffer from hearing loss, but also having captions improves search. The problem is, it's a lot of work to produce captions. Or rather, it used to be. The video editing software that I use, Blackmagic Design Da Vinci Resolve, is now able to produce automatic captions from the audio track using speech recognition. While it is definitely not perfect, it is a great starting point that I can manually add it to fix the mistakes and then produce transcripts with timestamps and upload these to YouTube. And I have now done that for all my videos, but not for the shorts and not for the old streams.
