Recording of Photon Transactions for 'INSTANT REPLAY' ?

Does Photon or Unity implement any data recording mechanisms that will allow Instant Replay of a video game?

I would like to continuously record the last 30 seconds of current game play. A user can then can pause the game and be shown an "Instant Replay" video of cool game events, such as a player exploding.

To solve my problem: Unity plugin video recorders are huge performance hogs. Alternatively, recording GameObject change deltas would be more efficient.

Photon transactions would be ideal to save/serialize to memory during game runtime.

Thanks!
