Sometimes getting a steam achievement in any game can result in some funny stuff. I think sometimes it'd be neat to clip it.

Titanfall executions are usually right at the end of a firefight, either between pilots or titans, and are the coolest things to clip, so being able to auto-clip those would be super useful

Should be pretty easy to track kills vs players and would really improve the experience when clipping new world

It could work where it starts/marks a capture at the start of a run and stops/marks at the end

Capture when you kill or die to a raid boss/encounter(or simply the full raid encounter), good for highlights and improving gameplay to see mistakes after a wipe.

goals, fouls, goalkeepers highlights

This would benefit mtga players a lot allowing them to capture highlights. As for powerful card placed, there is an event for this that triggers a flare in the dynamic music. The "someone says nice trigger" would go off whenever someone says nice ...

Kills, Death. Knocked, Win, Lose, Defuser plant, Defuser destroyed (i guess that counts as win/lose)

It would save the replay of the last 10 seconds before failing/restarting/completing a heist
