InVideo and Heygen, as well as Synthesia, are the current prompt-based AI video makers that dominate the market.
I'm sorry to say that they are far from perfect.
You would be better off just hiring a low-cost virtual assistant to create standard videos.
A lot of the video snippets, as well as AI-generated images that they pair with the audio, simply don't match.
For every 10 videos that get it right, maybe there are a hundred AI-generated videos that get it completely wrong.
AI video making is still a long ways away.
I'm not saying that it's not the future, but you should focus on producing videos that actually serve the interests of your channel's audience.
This is the way to build a solid business.
It's all about the end user.
It's all about the experience that they get, because ultimately, they are the ones who will be putting money in your pockets.
