Replacing faces service
My friend makes videos where he substitutes people's faces. He tried a few paid services, but there are problems: the video quality is low, the faces aren't replaced right.
So, the main issues are the quality of the video and the substitution. We might build a service that provides a better video quality which means higher processing time on a server. To leverage this issue, we could provide custom plans where users would choose video quality. For example, 720p is priced more than 480p. Notice that it's hard to render such videos and probably you'll need performant GPUs for cloud hosting.

The second issue is the quality of the face substitution. To handle this we could use custom parameters provided to end-users but simplified to their understanding. So the service can be used by not only programmers, video professionals, or deep learning engineers. Our target is regular people that aren't familiar with underhood face replacement magic.
There are some open-source projects for that, so probably you don't need to re-create a wheel. I guess it needs a custom configuration to handle various kinds of videos and faces to be handled in the service and to provide a friendly API for users.
