I have 30 images (a sequence) where I need a timer removed (transparent)

Hi there,

I have a 30 image sequence wherein I need a ticker removed from a fake bomb. I've attached two frames as well as an ideal before/after. I'm hoping for consistency where the ticker/timer is removed. I intend to add my own graphic (count down) to the timer.

I'd like a 30 image PNG sequence with alpha channel (transparency where there was the timer) as the final export - returned back to me within FIVE business days. Thanks in advance!!

*I'm looking for a cleaner line than provided in my example - it was rushed and I hope for a consistent line*
