Just adding my voice to the chorus. Allowing clients to add videos to the Gallery field is extremely useful functionality.
I appreciate that support provided a workaround, but it’s quite cumbersome, and I’d prefer to see this handled through ACF’s admin GUI.
To me, the obvious solution seems to be to respect file types defined in the field’s Allowed File Types list. Out-of-the-box only images are allowed, but developers can choose to override that behavior by adding other file extensions (or mime types) to the list.
