Yes, you can monetize your video with sound effects from FoleyCrafter. However, since it uses a checkpoint from Auffusion, which is trained on non-commercial datasets and thus has a non-commercial license, please acknowledge Auffusion and the datasets. You can do this by including a GitHub link, an arXiv link, or simply mentioning the name of Auffusion.

So I simply just add the following three lines to my video description. FoleyCrafter is based on Auffusion. https://github.com/open-mmlab/foleycrafter https://github.com/happylittlecat2333/Auffusion
