Also worth noting is the more-than-adequate sound volume coming from those speakers. We played the demo video at maximum volume, and the backplate vibrates with the sound. So, expect to feel the shaking when playing music or video at full volume while holding the device with your hand.
HD-TVI cameras are a type of analog high definition CCTV security camera (megapixel video over coaxial cabling / HD over coax) that supports up to 1080p video resolution. HD-TVI cameras are a great alternative to traditional analog CCTV and megapixel IP surveillance cameras because of their superior video quality and ability to use RG59 coax cable. TVI cameras are used by professional and DIY installers because they are so affordable and simple to install. Learn more by reading our article: What is HD-TVI?

The vast majority of video content today is 1080p, aka HD. Depending how it's shot and how it's played back, HD looks pretty good even on 4K TVs. It looks great on the small screens of mobile phones and tablets. So why not just record everything in 1080p?
In theory, 8K video should be significantly sharper than 4K, and especially HD. To see all this additional fine detail you're going to need an 8K TV. However, there are some potential sharpness advantages even on lower-resolution screens. Whether you edit and downconvert in some editing software like Adobe Premiere, or upload the videos to YouTube or Vimeo and let that site/app send lower-resolution streams to your phone or tablet, it's possible the resulting image will appear sharper than if you'd recorded the same video at the final resolution. Or to put it another way, because it's starting with more pixels, an 8K video converted and watched as 1080p might appear sharper than a 1080p video watched as 1080p.
Long the realm of oddball photographers (myself included) 360 cameras are starting to become more mainstream with their ability to record everything, and then let you create a highly crafted 16x9 video of just the interesting bits. The problem has been that even models that record 5.7K video don't look as sharp as a "normal" 4K camera because they're only showing one small portion of the entire video "sphere" at any one time and usually at 1080p.
But real 4K video sources are still few and between, which means most of us will be watching content in good, old-fashioned "regular" high-def: 1,920x1,080 (1080i or 1080p) or 1,280x720 (720p), both of which have far fewer pixels than 4K.
Here's the problem. Your 4K TV has a resolution of 3,840x2,160 pixels. Pretty much all cable, satellite, streaming, gaming, Blu-ray and other video content is 1,920x1,080 pixels (which is called 1080p and 1080i) or 1,280x720 (called 720p).
It's also worth noting just because content is in 4K resolution, that does not necessarily mean it's "good." I've seen some convincing demos where pristine upconverted 1080p content was shown on a 4K TV, side-by-side with the true 4K version of the same content on a second identical 4K TV. It was hard to tell the difference, even up close.
But that wasn't a real-world demo. In the real world, most content isn't pristine. In the real world, streaming 4K content from Netflix or Amazon can look worse than 1080p Blu-ray. CNET's hands-on comparisons of 4K streaming (and 4K from a Samsung UHD content pack and from Sony's 4K video player ) versus Blu-ray showed very little difference for the most part, and at times the Blu-ray looked better.
Like any marketing, take the claims from TV manufacturers with a grain of salt. Good upconversion can improve the apparent detail in an image; I've seen side-by-side demos that make 1080p look nearly as sharp as 4K. Admittedly these were put on by a company which makes scalers, but the potential is there, just as it was in going from standard to high definition.
Samsung unveiled the S II on 13 February 2011 at the Mobile World Congress (MWC) in Barcelona. It was one of the slimmest smartphones of the time, mostly 8.49 mm thick, except for two small bulges which take the maximum thickness of the phone to 9.91 mm.The Galaxy S II has a 1.2 GHz dual-core "Exynos" system on a chip (SoC) processor, 1 GB of RAM, a 10.8 cm (4.3 in) WVGA Super AMOLED Plus screen display and an 8-megapixel camera with flash and 1080p full high definition video recording. It is one of the first devices to offer a Mobile High-definition Link (MHL), which allows up to 1080p uncompressed video output to an MHL enabled TV or to an MHL to HDMI adapter, while charging the device at the same time. USB On-The-Go is supported.
The Galaxy S II comes with support for many multimedia file formats and codecs. For audio it supports FLAC, WAV, Vorbis, MP3, AAC, AAC+, eAAC+, WMA, AMR-NB, AMR-WB, MID, AC3, XMF. For video formats and codecs it supports MPEG-4, H.264, H.263, DivX HD/XviD, VC-1, 3GP (MPEG-4), WMV (ASF) as well as AVI (DivX)), MKV, FLV and the Sorenson codec. For H.264 playback, the device natively supports 8-bit encodes along with up to 1080p HD video playback.
The micro USB port on this device also supports USB OTG standard which means the Galaxy S II can act as a 'host' device in the same way as a desktop computer, allowing external USB devices to be plugged in and used. These external USB devices typically include USB flash drives and separately powered external hard drives. A video demonstration on YouTube has shown the OTG function to be readily available with an ordinary micro USB (B-type) OTG adaptor. The same YouTube video goes on to mention a successful test completed on a 2 TB USB external hard drive (requiring own power source) but however reports of failure when trying to connect USB keyboards, tested USB mice and tested USB game pads. Currently the only file-system supported for USB drives within OTG is FAT32.
Mobizen is also a great screen recorder for Samsung A6, if you do not prefer using the Game Launcher or if it is absent in your Samsung phone. It is a third-party app that records within the apps as well as App and Home screens. Additionally, it enables viewing, editing and sharing of your recordings. It comes with a settings menu that allows you to change video resolution up to 1080p and frame rate up to 60fps and adjust audio settings as well.
To fix poor TikTok video quality, you have to manually set the maximum video quality before recording. Select 1080p video quality and 30 frames per second or higher for maximum TikTok video quality. Once the settings are right, you can create a high-quality TikTok in no time.

I've written about car audio gear and fitness tech (like running watches and cycling computers) at Crutchfield since 2005. I also carved out a niche producing demo videos for our in-dash car stereos. The hands-on experience I got with car stereos while making these videos was an invaluable aid to me in learning about their exciting features and then explaining them to our customers. I began editing for our outstanding team of writers in 2021. 2b1af7f3a8
