Sorry, removing the date is not possible at this time.
It was inspired by how printed photos looked many years ago.
We believe that one of the primary elements that make a 1SE video so special is the date stamps which allow us to truly feel the passage of time. It's a glue for what, otherwise, might feel to a viewer like a bunch of random moments flashing by. It gives the video context.
But we get it, not everyone agrees with that. So we're working on adding a way to remove it.
Hang tight, it's coming!
