Car hit effect Tutorial - After Effect



I performed independent research and found this tutorial on Youtube which I followed to help me create the car hit effect on After Affects for my trailer "her smile". I have learnt from this that two shots are needed. One shot of the car passing by and another shot of the characters walking past and curving their bodies to create the effect of a car hitting them. These two shots are then edited to create a car hit animation.

Shots I have used to create this car hit:


After editing - Final Car Hit Animation

Variable speed changes: iMovie

iMovie can be used to speed up certain sections of the video clip. To do this you will have to hold down R on your keyboard and drag out a portion of the video clip you want to adjust.


 Select the speed control option and select your preferred speed. The adjustment will only be applied to the selected range.


To ensure there is a smooth transition between the speed segments, select the smooth option.

Correcting blurry/distorted video footages

During the production of my film trailer, I have found out that some footages were out of focus or blurry due to quick movements of the camera. With the result of this I concluded a research to see if there was a solution to this problem. I found out it is called Rolling Shutter Distortion and to edit a video clip to reduce its distortion, iMovie can be used by using its Rolling Shutter feature. This is a very helpful tool as it saves time from having to reshoot an entire shot, especially for this low-budgeting film trailer. However, if the quality of the clip is honestly bad you will have to reconsider a reshoot it to produce the highest quality film trailer. To do this, the following steps below needs to be followed: 

1. In the movie timeline, select a clip by clicking on it to edit a blurry or distorted clip.


2. Click on the adjust button.

3. A adjustment bar will then be displayed above the viewer. To display the stabilisation options click  on the shaky video button.


4. Select fix rolling shutter tick box. It will display as a red dash indicating that imovie is making this adjustment to the video clip. The length of the video depends on how long it'll take.




5. When iMovie is done applying the rolling shutter adjustment, the fix rolling shutter tick box will display a tick.



6. You can watch the preview of the clip that was adjusted in the viewer by hovering your mouse into the viewer. Playback options will then appear, click on the play button to play. 


7. If you change your mind and want to remove the Rolling Shutter Adjustment. Click on Remove Stabilisation Adjustment button.
