I’ve noticed videos with solid write ups do better, this is something people coming from other platforms miss a lot. Detailed text, a few pics or links will go a long way.
Also, dtube sometimes takes 30 min for the video to work after the upload. So for the first 20/30 minutes sometimes your video wont play , if dtube is budy and flooded.
Having that text allows people to read what the video would be saying and you get many upvotes that way too. Without text they would just see a frozen video with limited text and move on.
