Upvoting you because my comment saying the same thing is getting downvotes and I really think the message is important.
However I don't think it's fair to call this a "shallow wrapper". It's clear that a lot of work went into the design of this GUI and, and making user-friendly interfaces is also an important work (that is far too often overlooked in the open sources communities).
Yet the fact that FFmpeg, the tool that does all the heavy background work, isn't even mentioned anywhere on the website, even in the FAQ or the footer is at least a non-negligible ethical problem.
UPDATE: The same goes for ImageMagick that I just saw this app installs and uses too.
I have not downloaded the app, so I don't know what it contains.
The licenses for both ffmpeg and ImageMagick do not require anyone to mention them in the website.
However, if they are being re-distributed, there are clear obligations for providing source code and attributions. Omitting to do so is a violation of the legal obligations.
