60i: because it is an ‘interlaced’ format it describes a recording mode where 60 fields per second are recorded. For technical reasons that standard defined an effective 29.97 interlaced frames per second for NTSC Color TV.
What is 60i in video?
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.
Whats better 1080/30p or 1080 60i?
If you will be watching on a HDTV, which handles 60i properly, you can use 60i. However, if you will be watching on a computer or scaling the video, 30P will definitely be better.
Is 60i good?
Either 30p or 60i is better, except possibly in low light when motion is low. If the GH2’s 24p mode looks good, it may owe mostly to the high bitrate, but is probably a bear to edit without a 3GHZ+ i7 machine or better.
What is the difference between 1080/60i and 1080 60p?
1080 60p = 60 1920X1080 frames per second – the smoothest and the future of HD video. 1080 60i = 60 1920X540 interlaced fields recorded on 30 frames per second – half the resolution.
What is 60i FX?
60i 24M(FX)/50i 24M(FX): Records the movies in 1920 × 1080 (60i/50i). Bit-rate: 24 Mbps (Max.) Records the movies in 1920 × 1080 (24p/25p). This produces a cinema-like atmosphere.
Is 60i the same as 30p?
Larry replies: Chris, this is not, ah, completely true. A 60i format shoots 60 fields a second, which get combined into 30 frames a second. Each frame consists of two fields, each 1/60th of a second apart.
Why does my TV say 60p?
Although both mean 60 per second, 60 fps refers to the device producing 60 images per second, which would also be 60 Hz in terms of physical units. But displays often run faster than that.
What does P stand for in 60p?
The numbers (24, 25, 30, 50 and 60) represent how many times the video frame is displayed per second. The letters indicate if the video frame is displayed using an interlaced (i) or progressive (p) format.
What is progressive and interlaced video?
Progressive scan video content displays both the even and odd scan lines (the entire video frame) on the TV at the same time. Interlaced video displays even and odd scan lines as separate fields. The even scan lines are drawn on the screen, then the odd scan lines are drawn on the screen.
What does 1080p mean on a TV?
1080p (1920×1080 progressively displayed pixels; also known as Full HD or FHD, and BT. 709) is a set of HDTV high-definition video modes characterized by 1,920 pixels displayed across the screen horizontally and 1,080 pixels down the screen vertically; the p stands for progressive scan, i.e. non-interlaced.
What is 1080p 60i?
1080 60i can also = 30 1920X1080 frames recorded in 60i progressive segmented frame format – how many consumer AVCHD camcorders and digital cameras record 1080 30p. Apple TV, YouTube, and Vimeo WILL eventually support 60p videos in the near future since more and more cameras shoot 60p!
How many frames per second does a 60i video camera record?
A 60i video camera recording leads to effective 30 frames per second because 2 fields are required for one full image frame. Since 60i refers to NTSC (color) standard the effective frame rate is actually 29.97 (because the standard used a certain algorithm to get around some issues).
Why does fcpx output 1080 60i instead of 1080 30p?
When a 1080 60i clip is added to the timeline and then “Shared” (exported), FCPX will default output a 1080 30p .mov (or .mp4) video like this: The upper 1920×540 field is used and the lower 1920X540 field is discarded, losing half the resolution and 30p will never be as smooth as 60i or 60p.
What is the difference between 60i and 30p?
As video, both are about the same. Some HDTV screens turn 60i into 30p anyway. Some 120hz or 240hz screens may convey a smoothness akin to video shot in 60p. 60i video shot with a 60hz sensor should look smoother and feature less rolling shutter effect than 30p video shot with a 30hz sensor.
