We have seen the power of Blender with modelling and animation. Blender also has a powerful video sequence editing facility. Operating at a higher conceptual level, and used later in the video production process, Blender's legacy Video Sequence Editor (VSE) operates on a set of entire strips at a time, as a chunk of footage. The many parts of Blender work together in typical workflow fashion:
3) Model to construct the objects.
4) Assign materials and introduce lighting to colour the
objects.
3) Animate your objects to make them move.
4) Render layers of video using cameras.
5) Use compositing nodes to:
• Enhance the images by adjusting colours, also adding in-scene special effects.
• Layer the images into a composite image sequence (strip).
6) Assemble the video strips together to make a movie using the VSE.
The VSE within Blender is a complete video editing system that allows you to combine multiple video channels and add effects to them. Using the VSE, you load multiple video clips and lay them end-to-end (or in some cases, overlay them), inserting fades and transitions to link the end of one clip to the beginning of another. Finally, add an audio track so you can synchronise the timing of the video sequence to match it. The result of using the VSE is your finished movie.

Blender comes with a few screen layouts, one of which is '5-Sequence' (Figure 4). The screen layout is shown on the right. The main windows are: an IPO window, one VSE window on the top row and another in the middle, and a time line window below that,with the base Buttons window at the bottom.

The IPO window is in sequence mode. When you animate a sequence, its IPO curves will show up there, so you can make fine adjustments to its motion. The black VSE window is set to show you a preview of the finished sequence. Upon opening, it is black because there isn't anything to show.

The middle VSE window, in sequence mode, is your work area. The VSE window is in the middle, because this is where you will be doing most of your work; being in the middle means your mouse has to travel the least distance, and you are being efficient! Keep this in mind when you arrange any screen layout.
The time line window below it lets you select where (time-wise) in your animation you want to work, and allows you to quickly set the range of animation you want to scrub. Use the time line window's VCR buttons to playback the animation.
VSE is very flexible for editing your video footage as well. You can preview your footage in it, and at the same time, edit many sequences of your movie alongside. It offers a number of built-in and plug-in effects to transition from sequence to sequence, providing advanced Hollywood-style effects for a professional-looking video. Instruct Blender to use the output of the VSE by enabling 'Do Sequence' in the Buttons window-->Scene Render buttons-->Anim panel.
