Website visitor wants to view one of my videos. He clicks on a button, scripts create a copy of the source video, in the copy his name is embedded, at moments and positions determined by my specifications. For example a 30 minute video, with his name embedded at 10m20s during 10 seconds in the center of the screen, and at 12m32s during 20 seconds in the top right corner of the screen. When the video is finished processing, it is presented to the visitor. I already use ffmpeg scripts for this with a workaround for making the processing faster but these were made 10 years ago and I wonder if things can be made better and easier using the latest ffmpeg or AI developments. Additional functions are loading details from a DB table and inserting details into a DB table once the video rendering is finished. Depending on how much you can improve this, my budget is 250 to 500 euro.
