I want to share a little about the motivation and background behind the service, this is a service to add speech, subtitles and background music to a mp4 video.
The very beginning of this service was a couple of scripts to help me power up my video tutorial, intros, reviews, etc for all my products and services, I saw that the difference of the resulting video with those 3 simple elements was amazing!! especially after just investing a couple minutes of work.
I started offering the service with a UI to other users to get feedback and add features to the service, a lot of the features and workflows are based on their use cases and feedback.

You can see the difference of the same video with and without the processing:
