I run a YouTube Shorts channel and will quickly edit a short video down to 16:9 aspect ratio less than 1 minute long for you with your provided short clip. These mobile format videos work in TikTok, YouTube Shorts, Instagram Reels etc. I can cut out relevant sections or resize the whole video. As well as cut out the camera and place it the final video. I am also open to running and posting the videos to your channel the terms for this would need to be discussed.
My experience is operating a Shorts channel based on Twitch clips, it has grown rapidly and I would be happy to do the same for you!
