Nobody in that video did anything wrong in my opinion and for what the Highway code says.
You MUST NOT enter the box until your exit road or lane is clear. However, you may enter the box and wait when you want to turn right, and are only stopped from doing so by oncoming traffic, or by other vehicles waiting to turn right.
It looked like you tried to stay out of the box but you would have been fine inside the box or just outside it like you did.
The light was green when you crossed the white line and was waiting to turn right. It changed to red whike you were waiting to turn right and was blocked by on coming traffic and NOT traffic backed up where you wanted to turn right which would maybe be a fine or a talking to.
The only time anyone would be in trouble there is if you were all going straight on and waited in the box OR the road you wanted to turn down was full so you'd be stuck in the box or block the road.
The lights at that junction should be set to give more time between changes to allow for people in the yellow box to turn right when the oncoming traffic stops flowing. I agree with a previous posted though and this is where you get muppets jumping the red and that buffer you get in the box turning right is gone.
