---------------------------+-----------------------------
 I tested video format support in WordPress 7.0 by generating multiple test
 videos in different formats.

 According to the official documentation for the Video Block:
 ​https://developer.wordpress.org/themes/classic-
 themes/functionality/media/video/

 The supported formats are listed as:

 mp4

 m4v

 webm

 ogv

 flv

 However, during testing I observed the following:

 Formats that work (not listed in documentation)

 .mov — uploads and plays correctly in both admin and frontend.

 Formats that partially work

 .avi — uploads, but does not play correctly.

 .wmv — uploads, but does not play correctly.

 Formats that do not work as expected

 .ogv — uploads, but does not display correctly in admin or frontend
 (although it is listed as supported).

 .flv — cannot be uploaded, although it is listed as supported in the
 documentation.

 Questions:

 Is it possible to restrict uploads in WordPress so that only fully
 supported video formats are allowed?

 Is there an official way to validate which video formats are fully
 supported and guaranteed to work correctly with the Video Block?

 Is the documentation outdated, or has format support changed in recent
 versions?

 Thank you in advance for clarification.
