A Turkish security source had previously told Reuters that the 15 Saudis, including some officials, left Turkey later the same day. The team arrived in Istanbul on two private planes, one of which landed after 3 a.m. (0000 GMT) on Tuesday while the second plane landed around 5 p.m. (1400 GMT) after Khashoggi entered the consulate.
Saudi Arabia's government has no explanation of what happened to Khashoggi, just saying that he left the consulate after his meeting. Republican Senator Lindsey Graham said it's "imperative" that the Saudi government give clear answers about what happened to Khashoggi.
The accounts in Turkish outlets were not able to be independently verified.
Whether this refers to the new General Directorate for Investigation as part of new Saudi state security departments created previous year is unclear. The footage does not show Khashoggi himself leaving the consulate.
Among the assassination team was a forensic expert who brought a bone saw to dismember Khashoggi's body after killing him, the Times reported on Tuesday, citing an unidentified "senior official".
Other names and photos of the 15, who Sabah said traveled on diplomatic passports, match officers in the Saudi Army and Air Force, as identified by previous Saudi media reports and in one case a Facebook profile. The Saudis, for their part, have not turned over any CCTV footage of his exit.

Jamal Khashoggi was once considered an insider to the Saudi establishment with links to the security and intelligence apparatus. He went into self-imposed exile in Washington DC, while also maintaining a base in Turkey. Khsashoggi was a prominent critic of the Saudi regime.
While living in Saudi Arabia, Khashoggi was told to stop writing or posting on Twitter, where he has more than 1.6 million followers.
The journalist went there to finalise his divorce so he could marry his fiancée, Hatice Cengiz. The two soon agreed to marry, but in order to do so he needed to finalise his divorce with his first wife in Saudi Arabia. She acknowledged the writer first visited the consulate on September 28 "despite being somewhat concerned that he could be in danger".
Turkey's Hurriyet newspaper and other media alleged Wednesday that the Saudi Consulate's 28 local staff were given leave on October 2 on grounds that a "diplomats' meeting" would be held there on that day.
"This much is true: He entered the consulate, and there's no proof that he came out", wrote Cengiz. They arrived on two charter flights last Tuesday, the day Khashoggi disappeared.
Delhi is hopeful that Saudi Arabia and other members of the Organization of Petroleum Exporting Countries will heed United States calls for production to be boosted by one million barrels per day, as promised in June, which might help bring benchmark prices down.
Earlier this week, Corker had said "there will definitely be consequences" if it turns out the Saudis were involved in Khashoggi disappearance, while Lindsey Graham, another Republican senator, said it would be "devastating" to the US-Saudi relationship.
