The video showed her alleged killer, a 14-year-old boy, who cannot be named for legal reasons, fatally injuring her and fleeing the scene following a row on November 25 last year.
Ava and her friends are believed to have got into an altercation with the defendant, who was with three other boys, over a Snapchat video of them filmed of her without permission.
CCTV footage showed Ava pushing the defendant in School Lane and him backing away, before raising his hand in front of him, showing a “reflective object”.
The video then showed him running away from the scene and Ava holding her hands to her neck.
The court was shown a picture of the knife allegedly used to stab Ava, which was later found discarded. The defendant denies murder.
