Standalone MP4 converter for the DDJ-RZX

So I've done some researching on what is the proper wrapper for MP4 videos that work with the DDJ-RZX, in which I love to no end, doesn't exist. But after thinking about how to really solve this issue.

I would like to suggest to the pioneer software engineers to create a standalone video converter that output compatible MP4s for rekordbox.

Then tie this software to the key for the rekordbox video module or a separate key that is purchasable for those that dont have the video module but would like the standard of having all of their MP4s in the same format going forward.

If anyone has a better idea please advise as I and others would love to hear it.

Thanks
