The man was identifies as Elkana Bohbot, who was abducted from the site of a music festival in southern Israel on 7 October 2023.
The footage lasts more than three minutes, showing Bohbot speaking in Hebrew.
AFP could not verify when or where in the Gaza Strip the video was recorded.
Bohbot was seen along with another captive, Yosef Haim Ohana, in a video released on Monday by the Ezzedine Al-Qassam Brigades, Hamas's armed wing.
In that footage, the two men spoke about the dangers they have faced since Israeli air strikes on Gaza resumed on 18 March, after more than two months of truce.
In Saturday's video, Bohbot again says the ongoing bombardment could cost him his life, pleading to be reunited with his wife and son.
Since Israel renewed its offensive in Gaza, Hamas has warned that the military operations could put the captives in danger.
Of the 251 captives taken on 7 October, 58 remain in captivity in Gaza, including 34 whom the Israeli military says are dead.
Israel's renewed attacks followed weeks of deadlock in talks to extend the ceasefire that began on 19 January.
