VTV THAI BINH 1 - Testcard Ident Music

The video you provided is an outro (or a sign-off) for VTV Thái Bình, which is the television channel for Thái Bình province in Vietnam.

The video shows:

The VTV Thái Bình logo and the text "VTV THÁI BÌNH".

A shot of a traditional Vietnamese wooden structure, possibly a temple or communal house, at night.

The message "Chúc các bạn ngủ ngon!" which translates to "Wish you all a good night!" in Vietnamese, indicating the end of the broadcast day or a program block.

There is an animated sequence with the VTV Thái Bình logo.

There's also some instrumental music playing in the background.

It seems to be the closing segment for the channel's programming.
