Matinee

• With the release of Unreal Engine 4.23, Matinee is no longer supported and will be removed from the engine in an upcoming release. Once removed, you will no longer be able to access or open Matinee files.

Please use the Matinee to Sequencer Conversion Tool to convert any Matinee sequences to Sequencer Sequences as soon as possible.

Which means UE4.24 will no longer have Matinee, but you can use the tool shown above to convert old Matinee sequences into Sequencer.

I use UE4.23 version thanks
