14.4 Rendering a Video Clip
Videos are made by combining a series of video clips (short sections of video). Video clips are
made from animation frames compiled into a sequence. Before you can render a video file you
must have an animation sequence.
The Perpetual Motion sequence ( Chapter 11 – 11.10) has created an Animation Sequence.
To Render the animation click Render in the Screen Header and select Render Animation or
press (Ctrl + F12).
Note: You may also render an Image from this location.
Blender Render will open and start making an image for each
frame of the animation and save it to the tmp Folder. The reason
for Rendering an image for each frame is that the default output
file type is PNG which is an image file. The same thing would
happen if you had JPEG selected. On a Windows 10 System the
/tmp\ Folder is located in the C: directory: (Hard Drive).

The File Path
The first four PNG files
To playback your rendered animation from within Blender you go to the 2D Viewport Editor
Header and click on Render and select View Animation (Figure 14.6). Click Esc to quit
Playing the animation at this stage is simply cycling through the sequence of image files that has
been created in the /tmp\ Folder. Ten Bouncing Ball image files constitute a very very basic
animation. Animations can run to thousands of image files which would accumulate and create a
massive storage problem on your hard drive. To save space you render the animation sequence
to a Movie File.
In the Properties Editor, Output Properties, Output
Tab, change the default PNG to one of the
options, for example AVI Raw, which is a video file
format (Figure 14.9). Video file formats compress the
data from the rendered animation into a
instead of the series of image files.
Important: Before you Render with the video file
format clean out the tmp folder.
