Question

What is 3:2 pulldown and when does it occur?

1) When converting 30 fps original content to 24 fps digital
2) When converting 24 fps original content to 30 fps digital
3) When converting 60 fps original content to 24 fps digital
4) When converting 24 fps original content to 60 fps digital

Answer 1

3:2 pulldown is used when converting 30 fps original content to 24 fps digital, using a 3:2 frame pattern.

Step-by-step explanation:

The correct answer is 1) When converting 30 fps original content to 24 fps digital.

In the process of converting video content between different frame rates, a technique called 3:2 pulldown is often used. It is used to convert video shot at 24 frames per second (fps) to a format that can be displayed at 30 fps. This technique duplicates and stretches certain frames, resulting in a 3:2 frame pattern that allows smooth playback on a 30 fps display.

For example, in the case of converting 30 fps content to 24 fps, the technique would remove duplicated frames to reduce the frame rate from 30 to 24 fps. This is done by showing 3 consecutive frames (3) followed by 2 consecutive frames (2), resulting in the 3:2 pattern.
