Pros
Pro Features a CPU powerful enough to play your videos
This laptop contains a powerful 4th Gen. Intel Core i7-4700HQ quad core Haswell processor, paired with the latest NVIDIA GeForce GTX 860M Maxwell discrete processor with up to 4GB VRAM memory. This means you have a CPU that's fast, and can handle the videos and other media that you'll be editing without any lag. You'll greatly appreciate and notice the speed, the more you edit.

Since the Lenovo Y50 only measures 15.23″ x 10.37″ x 0.9″ inches, and weighs only 5.29 lbs (2.4 kg), it's very light and easy to take with you. So if you need to go on trips and you still have to do some video editing, that won't pose a problem for you.
Pro Gives you good audio experience when it comes to listening to the videos you're going to edit
Lenovo Y50 has good JBL designed stereo speakers and a subwoofer with Dolby Advanced audio that will give you clear and immersive surround sounds. You can watch this video showing a Lenovo Y50 playing a movie.
