What gear do you use?
I make gear decisions based on individual projects. Will this project require me to shoot in low light? Do I need to wire multiple people for sound? What's the budget for this project? Those are just a few things to consider when it comes to gear selection.
What software do you edit with?
This one just depends on which workstation I happen to find myself in front of. My first editing experience was on Premiere Pro CS2, then I learned FCP7 inside and out in high school. Then I switched to Adobe Creative Suite CS5 and continue to use Adobe CC in Windows/Mac environments. Every now and again I cut projects in Linux, and in those environments I typically use Kdenlive, Gimp, Inkscape, and Blender. Again, it's not so much the tools as much as it is the VISION. Having a great vision for your project trumps tools every single day of the week.
