I love the new video post-format where once you click publish, then you can see the video player itself. This has been a long time coming and makes it so much nicer.
Right now, the only time I see the video player is after I click publish. It would be nice to be able to see the video player once a video url is entered into the metabox instead of waiting for the publish button press.
It would just make it that much easier to use knowing I have the right video url/embed code/etc prior to publishing.
*I love this new feature so much that I want to add the same logic to my post metaboxes. Is it fairly easy to reuse this new WordPress code in a metabox? If so, where is this new video post-format (display video player) logic located?.... thanks
