Blender camera surround motion, animation rendering, video synthesis

use blender Make a display animation for your model

One 、 Surround movement

Add a camera and a circle —— Zoom the circle to the adjusted camera

Select the camera , Adding constraints —— Follow the path —— Path selection torus

After restraint , The coordinates of the camera go far away ,alt+G—— Restore coordinates

Click the animation path , The camera will start moving

Add another constraint —— Standards follow —— Select the house —— Adjust the following axis 、 Adjust the camera view up

Change the camera speed ： Find the first frame —— Select a fixed position in the follow curve —— Press... At the offset coefficient with the mouse I key k frame —— Drag the marker to 240 At frame , Change the offset coefficient to 1, Press I key k frame

Now it's the effect of gradual in and out , Adjust to the average speed ： Select two frames ——T Select interpolation mode —— linear

You can change the camera field of view by zooming and resizing the circle

Two 、 Rendering

stay “ Output ” Select file location —— Format PNG

3、 ... and 、 Video synthesis

Add video synthesis panel —— Add image sequence ——A Select all sequence frames

Four 、 Render export

Select Format —— The coding container is changed to MPEG-4

Be careful ： Lower the rendering and view , Otherwise, it's very slow

Be careful ： Set the moving object as a camera , Otherwise, the rendered screen will be black

5、 ... and 、 Video synthesis

Video acceleration ： add to —— Effect fragment strips—— speed control —— Cancel stretch to input strip length—— Use speed coefficient and stacking times to accelerate

Common shortcut key

0—— Camera angle of view
N—— Right property bar
Alt G/R/S—— Resume move 、 Restore rotation 、 Restore zoom
.—— Back to the object
I——K frame （ Mouse over the offset coefficient ）
A—— Future generations
