The two photos above illustrate an identical image at different native resolutions, which means the image's resolution and the TV's resolution are exactly the same. The first photo is a 4k image displayed on the Hisense H9G, and the second is a 1080p image displayed on the TCL 3 Series 2019.
Google is a giant in terms of computing power it needs and holds to enable billions of users to perform billions of more operations on Google Services every day. Video has always been an issue on the internet& purely on account of the bandwidth; it requires stream and processing power. From tiny videos with even tinier file sizes& we now have 4K UHD video streaming on YouTube& enabled by technology that is employed by commercial entities such as movie houses and end-users like you and me who now have unfathomable power in our pockets with multi-megapixel camera smartphones taking 1080p HD and 4K UHD videos day in and day out without batting an eyelid. The only time we seem to care is when either we are out of storage space or when the dreaded error comes up on Google when we upload our video& and it smugly reports back at us that it is processing the video.

On average& a minute of 1080p video at a standard frame rate of 25 or 30 FPS comes to be 1 MB per minute of video. Smartphones today can take videos at 60 fps and even 120 fps to enable slow-motion videography. The same minute-long 1080p HD video in 60 FPS becomes over 140 MB per minute. A 4K UHD resolution video at 25 FPS is close to 400 MB a minute. You get the idea - the better the resolution& the higher the file size of the video. Naturally& a few minutes of even HD quality video is going to be a few hundred MB& and it is going to take time to process for Google Photos& unlike your photos that are at max 20-25 MB in size for RAW photos taken with a 24 MP DSLR camera. File size plays a huge role in how often you might see the video still processing in Google Photos error.
1080p video signals are supported by ATSC standards in the United States and DVB standards in Europe. Applications of the 1080p standard include television broadcasts, Blu-ray Discs, smartphones, Internet content such as YouTube videos and Netflix TV shows and movies, consumer-grade televisions and projectors, computer monitors and video game consoles. Small camcorders, smartphones and digital cameras can capture still and moving images in 1080p resolution.
Any screen device that advertises 1080p typically refers to the ability to accept 1080p signals in native resolution format, which means there are a true 1920 pixels in width and 1080 pixels in height, and the display is not over-scanning, under-scanning, or reinterpreting the signal to a lower resolution.[citation needed] The HD ready 1080p logo program, by DIGITALEUROPE, requires that certified TV sets support 1080p 24 fps, 1080p 25 fps, 1080p 50 fps, and 1080p 60 fps formats, among other requirements, with fps meaning frames per second. For live broadcast applications, a high-definition progressive scan format operating at 1080p at 50 or 60 frames per second is currently being evaluated as a future standard for moving picture acquisition. Although 24 frames per second is used for shooting the movies.[2][3][needs update] EBU has been endorsing 1080p50 as a future-proof production format because it improves resolution and requires no deinterlacing, allows broadcasting of standard 1080i50 and 720p50 signal alongside 1080p50 even in the current infrastructure and is compatible with DCI distribution formats.[4][5][needs update]
1080p50/p60 production format requires a whole new range of studio equipment including cameras, storage and editing systems,[6] and contribution links (such as Dual-link HD-SDI and 3G-SDI) as it has doubled the data rate of current 50 or 60 fields interlaced 1920x1080 from 1.485 Gbit/s to nominally 3 Gbit/s using uncompressed RGB encoding. Most current revisions of SMPTE 372M, SMPTE 424M and EBU Tech 3299 require YCbCr color space and 4:2:2 chroma subsampling for transmitting 1080p50 (nominally 2.08 Gbit/s) and 1080p60 signal. Studies from 2009 show that for digital broadcasts compressed with H.264/AVC, transmission bandwidth savings of interlaced video over fully progressive video are minimal even when using twice the frame rate; i.e., 1080p50 signal (50 progressive frames per second) actually produces the same bit rate as 1080i50 signal (25 interlaced frames or 50 sub-fields per second).[4][5][7]
EBU requires that legacy MPEG-4 AVC decoders should avoid crashing in the presence of SVC or 1080p50 (and higher resolution) packets.[9] SVC enables forward compatibility with 1080p50 and 1080p60 broadcasting for older MPEG-4 AVC receivers, so they will only recognize baseline SVC stream coded at a lower resolution or frame rate (such as 720p60 or 1080i60) and will gracefully ignore additional packets, while newer hardware will be able to decode full-resolution signal (such as 1080p60).
In the United States, 1080p over-the-air broadcasts are currently available in select stations in some cities in the US via ATSC 3.0 multiplex stations where as ATSC 3.0 is currently rolling out throughout the U.S. The majority of the stations that broadcast at 1080p are CBS and NBC stations and affiliates. All other stations do not broadcast at 1080p and usually broadcast at 720p60 (including when simulcasting in ATSC 3.0) or 1080i60 (outside of ATSC 3.0) encoded with MPEG-2. There is also technical restrictions with ATSC 3.0 multiplex stations that prevent stations from airing at 1080p. While converting to ATSC 3.0 is voluntary by TV Stations, there is no word when any of the major networks will consider airing at 1080p in the foreseeable future on a national scale, although they are required to broadcast ATSC signals for at least five years thereafter. However, satellite services (e.g., DirecTV, XstreamHD and Dish Network) utilize the 1080p/24-30 format with MPEG-4 AVC/H.264 encoding for pay-per-view movies that are downloaded in advance via satellite or on-demand via broadband. At this time, no pay service channel such as USA, HDNET, etc. nor premium movie channel such as HBO, etc., stream their services live to their distributors (MVPD) in this format because many MVPDs, especially DBS and cable, do not have sufficient bandwidth to provide the format streaming live to their subscribers without negatively impacting their current services.[citation needed]
Blu-ray Discs are able to hold 1080p HD content, and most movies released on Blu-ray Disc produce a full 1080p HD picture when the player is connected to a 1080p HDTV via an HDMI cable. The Blu-ray Disc video specification allows encoding of 1080p23.976, 1080p24, 1080i50, and 1080i59.94. Generally this type of video runs at 30 to 40 megabits per second, compared to the 3.5 megabits per second for conventional standard definition broadcasts.[14]
Several websites, including YouTube, allow videos to be uploaded in the 1080p format. YouTube streams 1080p content at approximately 4 megabits per second[16] compared to Blu-ray's 30 to 40 megabits per second. Digital distribution services like Hulu and HBO Max also deliver 1080p content, such as movies available on Blu-ray Disc or from broadcast sources. This can include distribution services like peer-to-peer websites and public or private tracking networks. Netflix has been offering high quality 1080p content in the US and other countries through select internet providers since 2013.[17]
As of 2012, most consumer televisions being sold provide 1080p inputs, mainly via HDMI, and support full high-definition resolutions. 1080p resolution is available in all types of television, including plasma, LCD, DLP front and rear projection and LCD projection. For displaying film-based 1080i60 signals, a scheme called 3:2 pulldown reversal (reverse telecine) is beginning to appear in some newer 1080p displays, which can produce a true 1080p quality image from film-based 1080i60 programs. Similarly, 25fps content broadcast at 1080i50 may be deinterlaced to 1080p content with no loss of quality or resolution.
The current modern battle between HDR vs. SDR reflects the same trend. Although HDR has been commonplace in the photography world for some time, it is the new kid on the block in terms of television and monitors. Some have even gone so far as to argue that 1080p HDR looks better than 4K SDR!
Most mini projectors are less expensive than any room-to-room portable, and the Solar Portable is our top pick in the category. Even better, along with a low price, it fits a lot of features into a small package, including native 1080p resolution, built-in Android TV 9 for streaming over a Wi-Fi connection and for screen mirroring, and a built-in rechargeable battery that can outlast most full-length movies. Anker rates the Solar Portable at 400 ANSI lumens, which isn't as bright as most room-to-room portables, but we found it bright enough to fill a 90-inch screen in the dark and be watchable on an 80-inch screen in moderate ambient light.
The Solar Portable will appeal to those who are either on a tight budget or want a 1080p projector that's more portable than room-to-room models. Its only important limitation for watching movies is its audio. In our tests, the dual 3-watt speakers delivered distorted sound at top volume and offered no better than serviceable quality at mid volume. But if you already have an external audio system or powered speakers you can use with it outdoors, you can still get the benefit of the budget price. If not, the cost of the Solar Portable plus speakers may not save you money over a projector with a more robust onboard sound system. However, if you also need a fully portable projector for, say, business presentations on the go, it can save you the cost of buying separate projectors for home and work.
The conventional wisdom is that 3D was a fad that has long since petered out. That's undeniably true, but some people have libraries of 3D discs that they want to watch, and a lot of current projectors still offer 3D. The Horizon is one of them. It's also one of the least expensive 1080p models that's suitable for outdoor use and also offers high enough brightness to show 3D movies at a reasonably large size. On any projector, 3D is necessarily dimmer than 2D, so you need to start with a high 2D brightness to have any chance of having a good movie-watching experience with 3D. The Horizon's 2D modes are easily bright enough for an 80-to-90-inch screen in the ambient light typical of a backyard. You may need to drop the size a bit for 3D movies, but not by much. 2ff7e9595c
