Few versions back, the software has added advertisements. Fortunately, it seems like you can turn them off in the settings. If that didn't work, you can still download older versions without this antifeature - 11.000 seems good.


The software is actively updated and the advertisements are non-intrusive. Personally I do not find it so annoying, especially for free software of this quality. I did not know we could remove the ads, that's another reason for me to love this program! That said I'll leave them on, they do not bother me (as I dont need to watch the window during compressing) and if it helps to support the developer, so much the better.
