I think some of the artifacts on the video at 0:12 (handbag thing) are very noticeable. Same thing at 0:19 (cat)and at 0:28 (cat again). Otherwise, looks nice :)
Some scenes, foregrounds, backgrounds, lighting conditions, movements, etc work better than others - there's a lot of potential for errors in videos and the videos from the examples page are straight from Unscreen Pro. We're continuously working on improving the AI though (NB: We don't use video uploads for that - see unscreen.com/privacy)
