Coding your own video editing software

Hello /prog/ I have a question/challenge for you:

If you had to code your own professional video editing software what programming language would you use and why? How would you do it?

Also: Would it be possible to use asm language to make editing software?

This shit really happens? Has no one had the idea I had? Simply track a location, and every pointer pointing to it, and when none are left (Query this on pointer assignment) free said address, and keep all scoped variables in a ``scope'', and clean said scope when a function returns.

Virtual machines ``delay'' for GC? What the fuck is this shit? Is it really that hard?
