Ok so Ive been noticing the [video] posts. Its great that e621 is using new formats an all but... well. Users may start (its already started) ffding the old Gif and SWF posts that the video posts come from. Now it might not be a problem for some people but ive been noticing issues, for one not everyone may use this format thus not able to view them so the original format should stay Imo along with the new post, just parent/child it.
Secondly ive tried the video posts on both my kindle fire, and uptodate windows 8 gaming laptop. Kindle the player doesn't function, and windows 8 displays a "invalid source/source not found" error.
Sadly the uploader already flagged the child (original swf) post.
I think the users should get a bit of clarification on if we should ffd the old original formats or leave them for users who cant get webM to work.
