Journalist Lyra McKee, 29, was shot dead shortly after posting a picture on Twitter of the violence, which she described as "absolute madness".
The PSNI have made a decision to release the footage to the public "to encourage anyone with information" to come forward.
Officers say around 50 petrol bombs were thrown in the confrontation and two cars were burned out.
A vigil was held in the Creggan in Ms McKee's memory, organised by local residents who said they felt sad and angry. McKee was wounded after a gunman fired shots in a residential area, and she died from her injuries.
He offered sympathy to "her partner, her family and many friends".
The UK Prime minister and the leaders of political parties in the North have also condemned the violence and paid tribute to the award-winning journalist.
"Earlier this morning, I expressed my shock on behalf of all of the Irish people and our outrage too at the taking of the life of a talented writer, journalist, campaigner for rights", he said.
"This can not stand. Lyra's death must not be in vain because her life was a shining light in everyone else's life and her legacy will live on and the life that she has left behind", Canning said, CNN reported.
Investigators believe more than one person was involved and are treating it as a terrorist incident.
Her last tweet while reporting on the riot: "Derry tonight".

His full Twitter post read: "Heartbreaking & depressing news of the eruption of youth violence in Northern Ireland & the appalling terrorist murder of young journalist #LyraMcKee in Derry".
U.K. Prime Minister Theresa May called McKee's death "shocking and truly senseless", and opposition leader Jeremy Corbyn said it was "a reminder of the vital importance of protecting the Good Friday Agreement and Northern Ireland peace process".
"It's left me without the love of my life; the woman I was planning to grow old with.""She was bright, she was warm, she was witty".
In the post, she described the shame she felt at 14 as she kept the "secret" of her sexual preference from her family and friends and the love she received when she was finally able to reveal it.
