I can check the resolution of a video by
Right Clicking
->Properties
->Details
->Video
.Is there a way to see if the video is progressive or interlaced?

You should be able to tell just by looking at it. When you watch for motion and see a comb-like horizontal pattern, the video is interlaced. You could also try pausing the video at several points and looking for this pattern, but not every frame will look interlaced. Pause the video at points where there is quick motion, and step forward one frame at a time. Make sure the video is displayed at %100 zoom. If you find a frame which exhibits this pattern, the whole movie is interlaced. Once you know what to look for, you'll recognize it instantly.

Windows won't help you with this. There are several file info programs available. I use MediaInfo, which I like especially for the context menu entry 'MediaInfo' that allows you to quickly open video files and view their meta data in the program.
It shows mostly anything there is to know about the video file. The information you are looking for will be found under 'scan type'.

Mods for cod black ops 2 zombies. I use VLC Media Player. It will play most any format and will play DVD straight from the disc. Play the video and slow it way down during a motion sequence using the little double arrows next to the time line. It will clearly show the interlace if it is present.

If you have ffmpeg installed you can use the idet tool. Here is a guide on how to use it: http://www.aktau.be/2013/09/22/detecting-interlaced-video-with-ffmpeg/

Progressive scanning (alternatively referred to as noninterlaced scanning) is a format of displaying, storing, or transmitting moving images in which all the lines of each frame are drawn in sequence. This is in contrast to interlaced video used in traditional analog television systems where only the odd lines, then the even lines of each frame (each image called a video field) are drawn alternately, so that only half the number of actual image frames are used to produce video.[1] The system was originally known as 'sequential scanning' when it was used in the Baird 240 line television transmissions from Alexandra Palace, United Kingdom in 1936.

It was also used in Baird's experimental transmissions using 30 lines in the 1920s.[2] Progressive scanning is universally used in computer screens in the 2000s.[3]

Interline twitter
Interline twitter when the refresh rate is slowed by a factor of three, demonstrated using the Indian-head test pattern.
This rough animation compares progressive scan with interlace scan, also demonstrating the interline twitter effect associated with interlacing. On the left there are two progressive scan images. In the middle there are two interlaced images and on the right there are two images with line doublers. The original resolutions are above and the ones with spatial anti-aliasing are below. The interlaced images use half the bandwidth of the progressive ones. The images in the center column precisely duplicate the pixels of the ones on the left, but interlacing causes details to twitter. Real interlaced video blurs such details to prevent twittering, but as seen in the pictures of the lower row, such softening (or anti-aliasing) comes at the cost of image clarity. A line doubler shown in the bottom right picture cannot restore the previously interlaced image in the center to the full quality of the progressive image shown in the top left.
Note: Because the refresh rate has been slowed down by a factor of three, and the resolution is less than half a resolution of a typical interlaced video, the flicker in the simulated interlaced portions and also the visibility of the black lines in these examples are exaggerated. Also, the images above are based on what it would look like on a monitor that does not support interlaced scan, such as a PC monitor or an LCD or plasma-based television set, with the interlaced images displayed using the same mode as the progressive images.
Usage in storing or transmitting
Progressive scan is used for scanning and storing film-based material on DVDs, for example, as 480p24 or 576p25 formats. Progressive scan was included in the Grand Alliance's technical standard for HDTV in the early 1990s. It was agreed that all film transmission by HDTV would be broadcast with progressive scan in the US.[4] Even if a signal is sent interlaced, an HDTV will convert it to progressive scan.[5]
Usage in TVs, video projectors, and monitors
Progressive scan is used for most cathode ray tube (CRT) computer monitors, all LCD computer monitors, and most HDTVs as the display resolutions are progressive by nature. Other CRT-type displays, such as SDTVs, typically display interlaced video only. Some TVs and most video projectors have one or more progressive scan inputs. Before HDTV became common, few displays supported progressive-scan input. This allowed these displays to take advantage of formats like PALPlus, progressive scan DVD players, and certain video game consoles. HDTVs support the progressively scanned resolutions of 480p and 720p. The 1080p displays are usually more expensive than the comparable lower resolution HDTV models. At the debut of the 2010s UHD TVs had emerged on the consumer market, also using progressive resolutions, but usually sold with prohibitive prices[6] (4k HDTVs) or were still in prototype stage (8k HDTVs).[7] Prices for consumer-grade 4k HDTVs have since lowered and become more affordable, which has increased their prevalence amongst consumers. Computer monitors can use even greater display resolutions.
The disadvantage of progressive scan is that it requires higher bandwidth than interlaced video that has the same frame size and vertical refresh rate. Because of this 1080p is not used for broadcast.[8] For explanations of why interlacing was originally used, see interlaced video. For an in-depth explanation of the fundamentals and advantages/disadvantages of converting interlaced video to a progressive format, see deinterlacing.
Advantages
The main advantage with progressive scan is that motion appears smoother and more realistic.[9] There is an absence of visual artifacts associated with interlaced video of the same line rate, such as interline twitter. Frames have no interlace artifacts and can be captured for use as still photos. With progressive scan there is no need to introduce intentional blurring (sometimes referred to as anti-aliasing) to reduce interline twitter and eye strain.

In the case of most media, such as DVD movies and video games, the video is blurred during the authoring process itself to subdue interline twitter when played back on interlace displays. As a consequence, recovering the sharpness of the original video is impossible when the video is viewed progressively. A user-intuitive solution to this is when display hardware and video games come equipped with options to blur the video at will, or to keep it at its original sharpness. This allows the viewer to achieve the desired image sharpness with both interlaced and progressive displays. An example of video games with this feature is the Super Smash Bros. series starting with Melee, where a 'Deflicker' option exists. Ideally, it would be turned on when played on an interlaced display to reduce interline twitter, and off when played on a progressive display for maximum image clarity. Backup conf avaya ipoffice.
Progressive scan also offers clearer and faster results for scaling to higher resolutions than its equivalent interlaced video, such as upconverting 480p to display on a 1080p HDTV. HDTVs not based on CRT technology cannot natively display interlaced video, therefore interlaced video must be deinterlaced before it is scaled and displayed. Deinterlacing can result in noticeable visual artifacts and/or input lag between the video source and the display device.

Ps2 Progressive Vs Interlaced List Examples
Retrieved from 'https://en.wikipedia.org/w/index.php?title=Progressive_scan&oldid=898717490'
I just bought some component cables for my old PS2 to play some older games. The resolution now looks much higher now. However, I would like to make sure it is 480p and not 480i. I did not see any options on my TV for progressive or interlaced, and no options on my PS2. My television does support 480p (I checked the manual), as well as 480i, 720p, 1080i. The PS2 I have, I bought around 2004. It is one of the older ones (the bigger one, that the slim one). Do I have to do a PS2 system update or something?
Both interlaced (i) and progressive (p) have different advantages for different games. I read people talking about it online about choosing different i or p for their PS2.
I am out of ideas, either my TV does not have that option, my PS2 is too old, I need to update it, I mistaken those people by thinking they were talking about their console, but they were really talking about a emulator.
