In video technology, 24p refers to a video format that operates at a true 24 frames per second framerate -- or typically, 23.976fps when using equipment based around NTSC frame rates -- with progressive scanning (not interlaced). Originally, 24p was used in the non-linear editing of film-originated material. Today, 24p formats are being increasingly used for aesthetic reasons in image acquisition. Capturing video at 24p offers film-like motion, which is arguably more suitable for narrative projects and creates more film-like images. Some vendors market 24p products as a cheaper alternative to film acquisition.
When working entirely within the digital non-linear domain, 24p material is as easily handled as material at any other frame rate. However, 24p material requires care when it is processed using equipment designed for standard video frame rates.
There are two common workflows for processing 24p material using video equipment, one using PAL frame rates, and the other using NTSC frame rates. Of these two, the PAL route is the simpler, but each has its own complications.

Progressive or noninterlaced scanning
is any method for displaying, storing or transmitting
moving images in which all the lines of each frame are drawn in sequence.
This is in contrast to the interlacing used in traditional television systems
where only the odd lines, then the even lines and so on, of each frame
(now called a field) are drawn.

1080p
is the shorthand name for a category of display resolutions.
The number 1080 represents 1,080 lines of vertical resolution,[1] while
the letter p stands for progressive scan (meaning the image is not interlaced).
1080p is considered an HDTV video mode. The term usually assumes a widescreen
aspect ratio of 16:9, implying a horizontal resolution of 1920 pixels.
This creates a frame resolution of 1920¥1080, or exactly 2,073,600
pixels. The frame rate in hertz can be either implied by the context or
specified after the letter p (such as 1080p30, meaning 30 frames per second).
1080p is sometimes referred to in marketing materials as "Full High-Definition". Although 2K/4K digital cinema technology is commercially available, and ultra-high definition video is in the research phase, 1080p and 1080i are currently the highest-resolution formats widely used for broadcasting and consumer distribution of video content.
