I've had a look at both videos. Both show a pretty textbook contravention.
However, I believe we've had some success in the past with Redbridge YBJ PCNs as they always just state the location as a singular street name when in reality it is at the junction of two roads. Both PCNs are in respect of different box junctions along Ilford Lane, but this road is about 1 mile long and clearly has more than box junction along it (I say clearly as you have been caught in two different ones - they must be newish as they don't feature on Googlemaps yet so I cannot say specifically how many there are).
A PCN is required by law to state the grounds on which the authority believe a penalty charge is payable. If the location is unclear, there's a reasonable case to be made the PCNs cannot be enforced.
In respect of the first one, the time of contravention is also slightly wrong. It says 2232 when you entered the box (and stopped) at 2231.
