Able to save videos from this new demo recording feature in 4.6?

Hello, I was wondering if you are able to save videos to a file to upload to a website or something? I am currently trying to record some of my projects for my portfolio and so far every video recording software creates really laggy videos fro me =/ (it could just be my laptop is slow). So I was hoping if this new demo recording feature is smooth and also if i can export the video to upload somewhere. Thank you in advance.

This function saves the data to replay events, but not as video. It might be able to save to an image sequence check out the commands here: Command-Line Arguments | Unreal Engine Documentation
