Cancel Submit. Refund?

If someone need to correct his video. If that person cancel his own submission before getting challenged. Does that person gets his 0.128 ETH back?

S/He can cancel as long as the person is not vouched yet. And yes once s/he cancels, the deposit will definitely be returned.

If the submitter and the voucher missed some mistakes and wish to retract the registration, it’s better at that point (when cancellation is no longer an option) to challenge his/her own submission to get the deposit back and re submit.
