Are your video cables plugged into your motherboard or GPU?

Of those, Sweet Home 3D doesn't have native support for GPU rendering the files. From quick search, there are some plugins noted (Yafaray for example) which would add that. Another thread noted also exporting project and rendering it in Blender instead.

 

Of the quick search, iSkysoft Video Converter does not have support for NVENC. Like at all, only older NVCUENC is supported, so for cards up to GTX500 series. It might be that those sites I looked are outdated. GPU acceleration for encoding is not enabled by default, you need to enable it manually if there's option for it. If there isn't option to choose rendering engine, then software just doesn't support it.
