Uploading a gameplay clip to my steam profile?

use steam's own game recording if you aren't already, it's in settings under game recording. once a clip is saved you can share it or export it as an mp4 from the recording view. the profile part is where it gets annoying. steam profiles were never really built to host video, the old videos section just pulled from a linked youtube channel. so most people put the clip up somewhere else and use a screenshot or artwork showcase on the profile instead.
