Another thing to consider is that nearly all new HDTVs you can buy today are capable of de-interlacing 1080i video signals so they look just like 1080p, which makes it even harder to notice a difference.
1080p vs 960p vs 720p or 1080i
These days, 1080p and 1080i are old hat compared to the much more publicized 4K format available with most new HDTVs (often classed as UHD TVs). With 4K resolution, picture clarity is sharper and more colorful than ever. Consumers can also enjoy sitting quite a bit closer to their living room TV without noticing any sort of distortion in the image. This is because 4K TVs display close to four times the number of pixels as a standard 1080p set. Simply put, the more pixels on display, the better the picture quality. Better yet, most UHD sets will also upconvert a standard HD image, making your regular HD sources look closer to actual 4K.
D-terminal is a connector type used mainly in Japan. The resolutions supported by D1 to D5 are as follows:D5: 1080p / 720p / 1080i / 480p / 480iD4: 1080i / 720p / 480p / 480iD3: 1080i / 480p / 480iD2: 480p / 480iD1: 480i
Set the resolution.Select all resolutions supported by the TV in use. Video will automatically be output at the highest resolution possible for the content you are playing from among the selected resolutions.* * The video resolution is selected in order of priority as follows: 1080p > 1080i > 720p > 480p/576p > Standard (NTSC:480i/PAL:576i).If [Composite / S Video] is selected in step 4, the screen for selecting resolutions will not be displayed.If [HDMI] is selected, you can also select to automatically adjust the resolution (the HDMI device must be turned on). In this case, the screen for selecting resolutions will not be displayed.
With the introduction of the high-definition (HD) resolutions such as 720p and 1080p, the aspect ratio became 16:9 also named widescreen, and was established as the new worldwide standard by TV industries and laptop screen manufacturers.
Some recordings, such as in HDV video camcorders, and many HD TV signals are stored or broadcast at 1440 x 1080i. This is another bit of trickery used to reduce the amount of data needed to record or broadcast the footage. The pixels in the video are oblong (non-square). The pixel aspect ratio is 1.33:1. Essentially this means the pixels are stretched horizontally to fill a 1920 x 1080 frame during playback. This is hardly noticeable to the average viewer. You may also see 960 x 720 pixel video from some cameras. Again these employ non-square pixels to generate a 720p image.
Nearly all modern video cameras (PAL UK models) can do 1080p. Some but not all will do 1080i as well. In essence the choice of camera depends largely on how much you want to spend and what type of activity you want to film.
Yes, I'm doing that because once I bring my 1080i footage into the 1280 x 720p timeline, I set Spatial Conform to Type: None. This gives me the full resolution of the 1080i footage and allows me in effect "zoom in" without losing resolution (or at least that's my understanding from a tutorial). I'm guessing that's called reframing?
(I used to edit in 1080i timelines, but I think it was you who suggested that because my final product is going to be progressive, I should edit in a progressive timeline even though my footage is 1080i. So I decided to go to 720p because it allows the reframing and is progressive.)
720p models are adequate for many users, and cost about the same as more sophisticated cameras. Those featuring 1080p require more storage and bandwidth, but also provide greater detail for not too much higher a price.
1080p signifies high definition: 1920 pixels in width and 1080 in height, or a 16:9 widescreen aspect ratio. 720p cameras feature older technology, though legacy installations can be easily integrated with newer systems.
Real-time video streaming to a mobile device will be easier with 720p quality due to its lower bandwidth requirements. Most internet connections can easily stream at 1080p without issues, but a slowdown may cause lag with higher-resolution cameras.
No specific system can capture every scene, however a higher-resolution security camera provides a slightly better chance of collecting important details. Stiffer competition has lowered the price of 1080p cameras comparable to 720p models. An upgrade could be worth the slightly higher cost.
1080p: This is a new and upcoming resolution found on some HD-DVD and Blu-Ray discs that (IMHO) is completely over-hyped and does not look much different than 1080i in real world tests. While many CRT projectors are capable of displaying a 1080p signal, only High Performance 9" units will do so adequately (though some will argue that very high end 8" machines do have the resolving capabilities to do 1080p justice). If you decide that you do require 1080p resolving capabilities then you need to take this into consideration. For projectors with 8" and 7" tubes, it's best to use 1080i or 720p resolutions for HDTV.
Controls line multiplication setting for 240p/288p modes. NOTE: 3x/4x/5x do not generate standard 720p/960p/1080p/1200p CEA/VESA modes (total lines, pixels per line), so they are generally accepted only by monitors and not by many consumer TVs.

You must evaluate your network connection to determine whether it is strong enough to support your stream at your desired resolution. Streaming at 1080p60 requires more bandwidth than streaming at 1080p30 or 720p60. We recommend only dedicating 50% of your upload speed to your stream in case your connection suddenly becomes unstable or you encounter unexpected interference from sending across the internet to the streaming platform.
The encoded frame rate also affects the required bitrate. When streaming sports you could encode a 60 frames per second (fps) stream at 1080p60 or 720p60; for lower motion events like lectures or conferences, encoding and sending 60 fps may not provide a visible benefit, but requires significantly more bandwidth than streaming at the more common 30 fps. Not all online streaming platforms can accept a 60 fps stream, and not all viewers can handle receiving 60 fps, so be sure to take that into consideration.
So hopefully the CCTV resolutions make sense, but why do cameras have 1mp, 2mp, 3mp, etc? The number represents how many pixels that camera can capture. If we go back to the tv resolutions we had 720p down as 1280 x 720 pixels. So if we do the maths that equates to 921,600 pixels, or just under 1 million. So a megapixel (mp) is one million pixels. Likewise a 1080p screen is 1920x1080 pixels or 2,073,600 pixels, or just over 2 million pixels, which is just over 2mp.
The lowest of the common HD resolutions, 720p is widely supported and has relatively modest bandwidth requirements: an 8-bit 720p display requires less than 8 Mbits per frame. Note how the pixel clock of 720p is half that of 1080p (below): this simplifies your design if you need to support both resolutions. 2ff7e9595c
