 Channels
 ********
 
-Channels are horizontal tracks of along the timeline that contain content called Strips.
+A channel is a horizontal track that's similar to a layer in an image editing program:
-A strip can be an image, animation, or any number of effects.
+higher channels are displayed in front of lower ones.
-Each channel is numbered consecutively on the Y axis,
-starting from 1 and allows up to 128 total channels.
-The X axis of each channel represents time. Each channel can contain as many strips
-as it needs along the time axis as long as they do not overlap. If a strip needs to overlap another,
-it needs to be placed on a channel above or below the other strip.
 
+Within each channel, you can create one or more
+:doc:`strips </video_editing/edit/montage/strips/introduction>`, which contain either
+a segment of video content (a rendered scene, an external video file...)
+or an :doc:`effect </video_editing/edit/montage/strips/effects/index>`
+(color blending, blurring...). The X axis represents time, so the further a strip
+is placed to the right, the later it will play in the final video.
+
+While a channel can contain multiple strips, they can't overlap each other.
+If you want two strips to play at the same time, you need to place them in different channels.
