A developer friend asked me about the challenges of adding a watermark to a video. In the past, I’ve done similar things using video editing tools. However, they asked; was possible to add a watermark during an upload process, but it would need to be done with many videos and have logos and text information overlayed on the video. I wasn’t sure of any tool(s) but heard via another friend that AWS has transcoding tools and might have these capabilities.
To add watermarks and text via the upload process, you need to use AWS Elastic Transcoder command-line tools (here) and AWS S3 CLI (here). With these two tools, you can build scripts that can automate a backend workflow/process.
The video below highlights how to add a watermark(s).
