60p VS 60i

Interlace Scanning vs. Progressive Scanning


60p 촬영이란 무엇입니까?

AVCHD 60i는 비월 주사 시스템을 사용하여 초당 60 프레임을 촬영하는 과정이고 60p는 순차 주사 시스템을 사용하여 초당 60 프레임을 촬영하는 과정입니다.

AVCHD 28M(PS)으로 설정되면 영상이 60p로 기록됩니다. 그 외의 경우에는 60i로 촬영됩니다.



60i 뜻은?

60i (실제로는 59.94가 더 정확한 표현이다. 60i 필드 = 29.97 프레임): NTSC 텔레비전에 쓰이는 표준 비디오 필드 속도이다. DVD, 가정용 캠코더, 방송 신호에 쓰인다. 50i (50i = 25 프레임): PAL과 SECAM 텔레비전에 쓰이는 표준이다.



What do 60i(50i) and 60p(50p) in the recording format AVCHD 60i/60p(50i/50p) stand for?



For NTSC region:


AVCHD 60i is the process of recording 60 frames per second using the interlace scanning system while 60p records 60 frames per second using the progressive scanning system. When AVCHD 28M (PS) is set, movies are recorded in 60p. Otherwise, they are recorded in 60i.

The interlace scanning system displays even-numbered and odd-numbered scanning lines alternately. The progressive scanning system displays even-numbered and odd-numbered scanning lines on the entire video frame at the same time, thus it has double the information per unit time compared with the interlace scanning system.


For PAL region:

AVCHD 50i is the process of recording 50 frames per second using the interlace scanning system while 50p records 50 frames per second using the progressive scanning system. When AVCHD 28M (PS) is set, movies are recorded in 50p. Otherwise, they are recorded in 50i.

The interlace scanning system displays even-numbered and odd-numbered scanning lines alternately. The progressive scanning system displays even-numbered and odd-numbered scanning lines on the entire video frame at the same time, thus it has double the information per unit time compared with the interlace scanning system.

Difference Between Interlaced and Progressive Scan

Interlaced and progressive are the raster scanning technique widely used in analog video system. These techniques are distinguished according to the scanning process where the interlaced scan employs the scanning of odd and even marked lines of a picture that are displayed consecutively as two isolated fields which are superimposed to generate one frame or picture on the screen. On the other hand, progressive scanning sweep over the whole image at a time.
