4K Video
Simply support for exporting the video in the 4K quality!
Who's out/in board
Ability to add in a panel that shows for example who's alive in a game. The editor would upload a few pictures to display on a board that is for example on the video's top/side and when necessary set that the player on the picture is out, by making the picture black and white or putting a red cross over the picture (this could be decided by the user)
Time Counter
Counting the time since the effect was added in. Useful for displaying current length something has been going on to the user watching the video.
