Hello! A lot of good advice has already been given, and we don't want to be repetitive, so listen to the forum users. But we can't leave without giving our own tip
Consider starting with Youtube Shorts. The trend for short videos has been growing for several years now, so don't miss the opportunity to use this tool as an addition to your long videos. For instance, with Shorts, you can create: teasers for new videos, highlights from full videos, clickbait moments from full-length videos, and individual short clips on your topic.
You can do it, good luck!
