Im recommending them to anyone who wants free software and is willing to invest their time into understanding how to do things for free and without concern over their data. If you aren't willing to invest the necessary time it isn't for you and that's why I said it. It's okay if these don't work for you. That's valid. But it does, in fact, work for many others who are not you.

I mentioned the manual because you claimed you didn't know what the commands do. If you read and take the time to learn the manual like you said you can do, you will, in fact, understand how the commands work. Additionally, this is public forum, my post may have been a reply to you but I understand other people may read my comment. Other people may have your frustrations but are not aware of the manuals that tell them exactly how the commands work. It only takes a bit of elbow grease, perhaps people other than you are willing to apply it?

I'm not sure if you saw it, but I did mention a gui application for converting files. I admit, I don't use it, but many people also save a lot of money using it, so it might be helpful. I have no idea if it's useful for your needs though.

Here's "ffmpeg in 100 seconds" https://youtu.be/26Mayv5JPz0

Here's a video on ffmpeg and imagemagick: https://youtu.be/sKBM4M-kuCg

Additionally, you can just learn how to read man pages: https://itsfoss.com/linux-man-page-guide/

There's a neat little guide that'll help you learn how to read documentation.

Once you've read through that let me know what confuses you about documentation.
