Add a replay/theatre system.

It would be amazing if Respawn added a replay/theatre system to Apex Legends.

Reasoning:

• Reviewing gameplay from a third-person perspective in order to learn and improve.
• Post-Game reports, so someone can see if someone is actually cheating after the match already ended and report them.
• Allows users to record high-quality gameplay footage without the drawback of performance issues while recording and playing at the same time.
• Creative content creation, adding a replay system would allow people to create their own cinematic videos/high-quality recordings for content such as tutorials/guides, montages, etc. This would likely result in an increase in Apex Legends content quality and quantity, which also could result in an increase in players.
• Export and share replays/demos, which could allow for archival of gameplay. 

Ideas: 

• Dolly cam, keyframes for an interpolated camera path. This is mainly for content creators and editors so they can get the cool cinematic angles of gameplay.
• Change timescale. This would allow us to record in slow motion to record in higher framerates than we normally can. Also useful for reviewing gameplay. 
• Camera customization, Be able to change the depth of field blur, focal point, camera angle/tilt, etc.
• Switch between first-person, third-person, free cam, and dolly cam.
• Be able to change the time of day/sky lighting or fog.
• Greenscreen pass for viewmodels and players. Be able to toggle to show/hide first-person viewmodel, and show/hide world layer. This could allow people to record a chroma key isolation of just the viewmodel, and a version without the viewmodel. Would be useful for creative content. 
• Depth path for video editing.
• Frame perfect exporting of footage from start to end marked by keyframes as an image sequence or video file.
• The exporting and sharing of replays, if tournament/professional game demos could be downloaded or viewed through an "esports" tab in the Apex Legends lobby UI that would be neat.

If you agree or have any other ideas please don't forget to give this post some attention :D
