The licence on the software has no impact on the output. Even if you are using the software illegally, that doesn’t affect the output - if you write a novel using an illegal Microsoft Word, you own the copyright.
However, your rights to the output are affected by the status of the input.
If there is no creativity in the operation, that is, the output is always the same for the same input, then the output is the input as far as the copyright is concerned - it’s just a change of format like translating from a jpeg to a bmp.
However, if there is some creative input, for example, if the output changes by changing parameters, then the output is a derivative work with its own copyright.
In both cases, however, you have to have permission to make copies - because you own the copyright, have a licence or it’s fair use/dealing.
