I use a lot of kit to film and produce my videos, weirdly consisting of multiple video editors and other things - strange really, but it works...
Operating System: Windows 10 Home 64-bit
Processor: Intel Core i5-3570K (3.40GHz with 4 cores)
Memory: 16 GB (Unknown specification)
Motherboard: Asus P8Z277-V LX2
Graphics Processor: NVIDIA 760 Ti
I use an Apple MacBook Pro from 2013 for all on-the-go editing, it is still in very good condition - meaning it is still highly usable, even for editing.
Logitech G213 Prodigy Gaming Keyboard
Logitech G203 Prodigy Gaming Mouse
Logitech G432 Surround Sound Headphones (I love these)
Asus 27" monitor (S271HL)
I use a mixture of the following software to edit my videos (including video, audio, annotations - where appropriate and any other video editing resources I might need, for instance creating subtitle files and designing annotations)
Adobe Audition
Adobe Photoshop
Adobe Premiere Pro
Apple Final Cut Pro X
Apple QuickTime (for Screen Capturing on Mac)
Audacity
Google Drive
Handbrake
Microsoft Snip & Sketch (used a surprising amount for taking screenshots of other applications for use as annotations)
Microsoft Word
TechSmith Camtasia 2019 Pro
Vortex Digital Control (creating subtitle files and teleprompting where required)
Other programs used although not so commonly include: Xbox Console Companion Application (for screen-capturing Xbox to my Windows 10 PC), Visual Studio 2019 (for writing scripts and programs used within videos, as well as making the occasional programming tutorial), Excel (for keeping track of videos), Microsoft Teams (for communication with the Editing Team at Vortex Studios - who occasionally edit for me)
If you're looking to kit out a studio or production office or something, I definitely recommend getting these - or even if you aren't as they pretty cool bits of kit:
Amazon Echo Dot (or Amazon Echo)
Nest Home Mini (or Nest Home) - formerly Google Home
Wireless Charging phone stand (if your phone supports it)
Mini Fridge - because - why not?
Good setup of speakers - why wouldn't you?
