Auto Video builder using images & voice overs

Wanna create a software for making videos using pre fed multiple videos, images & audio. Multiple audio we shld be able to upload & control volumes. The images would be in png or jpg & the resolution of the output video rendered shld be HD. The duration of the video can be max 20 mins. Developers who have done similar software can contact with work references. I will also then give examples of output video etc in chats.
