Hi HN,
this is a tool I built for fun two years ago, which I now decided to release as open source.
It's a Java program that takes a Wikipedia page as input creates a video narrating the content of the page using a combination of sources for images and videos, plus Amazon Polly for speech synthesis.
At the time, I wrote a detailed explanation[1] of how the tool works, if you're interested.
The project is not active or currently maintained - I'm just releasing it because a few people requested it to me, and so I thought I might as well post it here!
EDIT: Forgot to specify: although, in theory, this works with any Wikipedia page, it might not do so very well (or at all) in a few cases. For example if the input page is very short or it has an ambiguous word which will then not result in good matching images from Pixabay.
As far as I can tell, this sort of use of Wikipedia content - even for a monetized YouTube video - isn’t inherently against the CC-BY-SA terms. Though, you have made one change, you created a character called the storyteller who introduces each text, and a brand for that channel. That might make it a little questionable legally, even though you credit Wikipedia in the description. Also under the terms of a ShareAlike license, it seems to me that you should also provide the raw generated video under the same terms.
Maybe do a little inquiry into how to do this right? It seems your project is basically abandoned now though?
