Definetly a Macbook running something like Finial Cut Pro for editing.
If you are going to spend $1000+ on a laptop, go with 1st tier manufacturer, not MSI which is a 2nd tier mobo manufacturer and 3rd tier computer mfgr.
For your requirements, I’d look at Alienware 15″ laptop because of the high-end graphics card — Nvidia GTX 1070. You’ll still need a high-res screen with as much pixels as possible. A SSD is a necessity for video.
If you were just doing programming, I’d lean towards a Dell Mobile Precision Workstation because of the dock. My personal Dell w/ dock drives 3 external 24″ monitors. Programming is so much easier with so much screen real estate.
i think Apple Macbook Pro with touchbar is best for you
CPU: Dual-core Intel Core i5 – i7 | Graphics: Intel Iris Plus Graphics 640 – 650 | RAM: 8GB – 16GB | Screen: 13.3-inch, (2,560 x 1,600) IPS | Storage: 256GB – 1TB PCIe 3.0 SSD
Macbook! - for sure!
speaking about the video editor Pinnacle Studio 21.5 - this one is the best for beginners (never change it to another one despite i am not a beginner anymore)
