You claim your rewards after 7 days, they keep your video alive for 45 days(you can download the video and play it) after 45 days video is removed- deleted)

No rewards will not disappear once it gets paid out. They only delete files off their servers (they may remain in the IPFS network), but everything else stays on the blockchain (including the link to the video).

The way d.tube interface works is that if video.dtube.top (their servers) returns a 404, it falls back to ipfs.io (aka the entire IPFS network). If videos exist in the IPFS network outside of DTube the video will play.
