I would recommend you to go with the Dell Inspiron i5378-7171GRY - Price $745
Specifications:
- 3.5 GHz 7th Gen Intel Core i7
- Intel HD Graphics 620
- 8GB RAM
- 256GB SSD
- 13.3-Inch FHD (1920 x 1080) IPS Truelife LED-backlit touch Display
As far as I know, these specifications are best for video-editing, gaming and other everyday works.
However, it only ships with 256 GB SSD, if you do enough editing you'll need an external storage.
I'm recommending you this because SSDs are way more faster than HDDs and I can't see any better option with SSD than this, under the price range of $750.
If you could manage all your edited videos in an external hard-drive then this laptop is the best!
