While I haven't gotten any requests for 4K multi-camera productions, I would feel guilty if I didn't plug in Blackmagic Design's top-of-the-line Ursa 4K cinema camera. I had to go into the switcher's set-up menu and set it for 2160p 29.97 to match the Ursa, but other than that, it was just like connecting any other camera. My only other 4K camera is a GoPro Hero Black 4K, but I didn't have the micro-HDMI cable on hand to get a signal out of it, so I couldn't do any actual switching. It should work the same as any other model. If I wanted to use the Ursa with my other cameras, I'd switch them from 1080i to 1080p, and either switch the URSA to 1080p or keep it recording at 4K with a 1080p output to the switcher.
Many times, I have seen resolution of 1080p and I know that it means 1080 pixels but I also have seen specifications on some HDTVs to be 1080i. So, I want to know the exact difference between them and whether 1080i video quality is available for the laptops too.
The question is specifically: What is the difference between 1080p and 1080i? so I will start by outlining the main similarities and differences, I'll add some tips on how to choose the best format and then I will proceed to explain the problems that I found here.
Please note that this answer is specifically about HDTV and talks about signals and resolutions that can be transferred with a standard HDMI cable. Other resolutions and frame/field rates are certainly possible but standard HD TV sets, game consoles, Blu-ray Discs etc. use only certain resolutions and frame/field rates described below (or at least they did at the time of writing this answer). Specifically this answer doesn't talk about: Ultra-high-definition television, Super Hi-Vision, Ultra HD television, UltraHD, UHDTV, UHD, 4K, 8K or anything beyond 1080p and 1080i that this question is about.
Both 1080p and 1080i have 1080 horizontal lines of vertical resolutionwhich with a widescreen aspect ratio of 16:9 results in a resolution of 1920 × 1080 pixels (2.1 megapixels). It is not true that 1080i has a lower vertical resolution than 1080p.
The drawback is that 1080p as currently in use has a frame rate that is only half of the field rate of 1080i so the motion is noticeably less fluid - in fact it's exactly twice less fluid which is a lot. You can see it on large flat TVs that often deinterlace the video to be able to display it on their LCD screens (that, unlike CRT displays, are progressive in nature) which is the cause that they display picture of very high resolution but with jerky motion and some deinterlacing artifacts.
Using progressive 1080p with 50 or 60/1.001 full frames per second in the future has a potential to eventually solve the above problems but it will require a whole new range of studio equipment including cameras, storage and editing systems so it probably won't happen anytime soon. The widely used SDI standard for connecting HD video equipment doesn't have enough bandwidth.
(It all assumes that 1080p has a frame rate of 25 or 30/1.001 frames/s, 1080i has a field rate of 50 or 60/1.001 fields/s and 720p has a frame rate of 50 or 60/1.001 frames/s as is currently the case. Hopefully a high resolution progressive format like 1080p with a frame rate of 50 or 60/1.001 frames/s or maybe even higher will make this recommendation obsolete in the future.)
I think that progressive scanning is indeed better in every respect, but if we are not talking theoretically about the idea of interlacing but specifically about 1080p and 1080i standards as used today, then one has to take into account the fact that 1080i is often required for TV broadcasting and converting 1080p to 1080i would result in jerky motion.
Again, yes, progressive is better than interlaced all other things being equal, but progressive video with frame rate that is two times smaller than the field rate of interlaced video (which is the case with 1080p and 1080i) is something very different, especially if interlaced video with high field rate is required for TV broadcasting and the high field rate cannot be reproduced from progressively recorded material with lower frame rate.
No. For LCD all 1080 lines are always displayed, for CRT displays usually much less than half of of the lines are displayed at any given time which is equally true for both 1080i and 1080p.
While it is true that the phrase "only 540 pixel rows are displayed at any given time" is extremely misleading, it is not true that the refresh-rate is cut in half, because in 1080i the refresh rate is two times faster than with 1080p so it is actually the other way around.
1080p represents 1920 pixels displayed across a screen horizontally and 1080 pixels down a screen vertically. However, unlike 1080i all pixel rows or lines are displayed progressively, providing the most detailed high definition video image that is currently available to consumers.
Sometimes an interlaced signal will be a progressive signal split into half frames ( e.g. Some Panasonic cameras have 1080p30 sensor output but (for some reason) write it out to a 1080i60 file. A more common case is of actual half frames, and if you freeze frame you'll see discrepancies between alternate lines in the still image.
One point I don't see mentioned here that I personally find significant... Many 4k TV's have built-in software to up convert a full HD picture to "NEAR 4K". However they must originate from a 1080p source. Many cable boxes are only capable of producing a 1080i picture. Just another consideration I felt compelled to add.CDEricson

Consumers who purchase both an Xbox 360 (which already includes a standard DVD drive for games) and the HD DVD add-on will spend the same amount of money as those who purchase a Sony PlayStation 3, which includes an expensive integrated Blu-ray drive. With its next-generation optical-disk advantage gone, Sony has had to resort to a single technical area in which the PlayStation 3 outshines the Xbox 360: HD output. In addition to the standard definition, 720p, and 1080i HD resolution that the Xbox 360 offers, the PlayStation 3will offer true 1080p output.
But this week, Microsoft announced that even that advantage has been nullified. It turns out that the Xbox 360 hardware has always supported true 1080p, and beginning this fall, the software giant will enable that functionality by shipping a free software patch to Xbox 360 users over the Internet. This patch will let Xbox 360 users display all Xbox 360 games and DVD movies at true 1080p; currently, the Xbox 360's firmware limits the device to 720p and 1080i HD output, with downsampling for standard definition. Suddenly, the Xbox 360 appears to have no serious technical limitations when compared with Sony's overpriced and repeatedly delayed PlayStation 3, although the Xbox 360 still lacks a HDMI connection. (However, you could conceivably add an HDMI connection by using a new cable connection kit, should one be made available.)
The DMC-GH2 can record high-resolution Full 1080p HD 1920 x 1080 movies at 24 frames per second, Full 1080i HD 1920 x 1080 movies at 60 frames per second, and 720p HD 1280 x 720 movies at 60 fps, all in the AVCHD (MPEG-4/H.264) format. In addition it can also record Motion JPEG movies at 320 x 240 at 30fps, 640 x 480 at 30fps, 848 x 480 at 30fps and 1280 x 720 at 30fps, useful as this format can currently be shared more easily. AVCHD features almost double the recording time in HD quality compared with Motion JPEG, but software support is still a little thin on the ground. Panasonic describe it as the best mode for playing back on a HD TV direct from the camera, and Motion JPEG best for email and playing on a computer. There is a limit on the length of a movie of up to 29 min 59 sec in European PAL areas, and continuous recording exceeding 2GB is not possible when recording in the motion JPEG format.
As for output capabilities, the BDP-S5000ES supports the output resolutions of 480i, 480p, 720p, 1080i and 1080p.Â The 480i option is handy if you have an external video processor that you want to use for DVD playback.Â The BDP-S5000ES supports the playback of Blu-ray media at 1080p/24Hz if you have a compatible TV and an HDMI connection.Â The player will also upscale DVD media to 1080p resolution.Â The BDP-S5000ES offers support for 30-bit and 36-bit Deep Color via its HDMI connection which may come in handy down the road as there is currently no Deep Color material available.Â The player supports Dolby TrueHD, Dolby Digital Plus, DTS-HD High Resolution Audio, and DTS-HS Master Audio.Â If you are using a receiver which supports HDMI 1.1, the BDP-S5000ES will output multi-channel LPCM.Â If you are using HDMI 1.3, the BDP-S5000ES can send the high resolution bitstream to your receiver based on the menu settings in the player. 1e1e36bf2d
