Has anyone made an Un-Record button?

[Towels]

I film Tricking events and only end up using the clips from landed clips. This means I have to sort through all the crashes in post.

I would love to have a button on my camera that I can press after recording a video and it'll delete the last clip real fast without pulling up a menu.


Another solution to my problem would be a marker button that you press while a clip is recording and it marks that clip with an extra symbol or something so when you go back through you can easily see the clips you plan on using.

Anyone know if anything like this exists?
