How to upload short videos (10-15 secs) from an Android App to AWS using Node.js?

Once the application gives me a GET Request for the file along with the video, what should we use in our Node.JS file to correctly optimize the video, compress/encode the video in which format and minimize the uploading time for end user?

I understand the file needs to be asynchronously uploaded. But what should be my backend systems be designed like?

We'll be using AWS, and Mongo DB. So all the videos will be uploaded to S3 Bucket. Is this the best practice?

Basic requirement is I am trying to make the uploading video as much scalable and concurrent for multiple users to upload video.

Are there any kind of best practices or tutorial for the kind of video formatting and uploading in Node.JS we are looking for?
