Both men, he confirmed are among four people at large whom prosecutors accuse of having the common intention with the two women to murder the estranged half-brother of North Korean leader, Kim Jong-Un.
Doan Thi Huong, 21, is charged, along with Indonesian woman Siti Aisyah, with using chemical VX to kill Kim Jong-nam in Kuala Lumpur airport, in Malaysia, in February.
Some of the footage, dated Feb. 11, appeared to show Huong approaching an unidentified man from behind and placing her hands around his neck and face, before backing away slowly with her head slightly lowered and her hands put together. Prosecutors however, contend the women knew they were handling poison.
That encounter was described as a practice session for smearing Kim's face with VX nerve agent, the court was told. She walked swiftly to a restroom, keeping her hands partially raised and away from her body.
Mr Wan Azirul told the court their hands were in normal positions after they left the bathrooms.
Wan Azirul named the two other at-large suspects as James, who is suspected of recruiting Siti Aisyah, and Hanamori, nicknamed Grandpa-Uncle, suspected of giving orders to Mr Y.
No further details about those four suspects were disclosed in open court, though Prosecutor Wan Shaharuddin Wan Ladin said outside court the four are believed to be North Koreans. He arrived in the country on Feb 6.
They then went to the taxi stand, where they got into a vehicle to leave.
A chemist testified earlier he detected VX on Huong's fingernail clippings and that the amount of VX detected on Kim's face exceeded a fatal dose.
The two defendants told police they were tricked into attacking Kim and thought they were merely playing a prank for a reality TV show. James had her go to malls, hotels, and airports and would film her as she rubbed oil or pepper sauce on strangers, paying Aisyah between $100 and $200 per prank.
The murder charge under Section 302 of the Penal Code carries the mandatory death sentence upon conviction.
James later introduced Aisyah to a man called Chang, who said he was the producer of Chinese video prank shows.
The defense lawyers for both Huong and Siti Aisyah said the videos could be considered hearsay, as the investigating officer did not record them himself and was not present to witness the crime.
