Hello all
I have read an article about this tool
https://github.com/s0md3v/roop ,it seems to be one of the best free ones actually to swap faces in both images and videos, you can check some examples here
https://drive.google.com/drive/folde...1yPSTWM554Gq8e .Unfortunetly I could not test it because when installing it it requires you to download a 2.3GB file and since I did not have time to wait for it I just quit it. I hope you will benefit from it and remember to not use it for unethical purposes, and if you know some other similar tools feel free to share them with us in comments.
