+## Utils
+### Video to frames
+`get_frames( )` method can be helpful when you want to grab all the frames from a video. Just pass the path to the video, it will return all the frames in a list. Each frame in the list is a numpy array.
+```
+import cvlib as cv
+frames = cv.get_frames('~/Downloads/demo.mp4')
+```
+Optionally you can pass in a directory path to save all the frames to disk.
+```
+frames = cv.get_frames('~/Downloads/demo.mp4', '~/Downloads/demo_frames/')
+```
