The martian real or fake 4k 1080p#

Action cameras offering fake, interpolated 4, mostly justВ offer 1080p with max. ThatвЂ™s not a reliable method, but most action cameras which offer native 4K at 30fps, also offer 1080p with 120 fps. Processors that canвЂ™t do 4K at a decent frame rate: The highest resolution possible is 2880 x 2160 with 24fps.В Sunplus 6350 (10fps) andВ Allwinner V3 (15fps)В are also not capable of 4K resolution with a decent frame rate. The famous Novatek 96660 chip used in many action cameras ( SJ5000x elite, Firefly 6sВ or Elephone Explorer)В is not capable of real 4K resolution.

Not only the sensor, also the processor has to be capable of 4K video resolution.

Sony IMX206 вЂ“ 16 MP (found in Xiaomi Yi, Git2, SJCAM M20, Yi Lite,вЂ¦).

Sony IMX078 вЂ“ 12MP (found in EKEN H8, Elephone Elite,вЂ¦).

Omnivision OV4689 вЂ“ 4MP (found in EKEN H9, Elephone ELE Explorer, Amkov AMK7000SвЂ¦).

When looking at the data sheet of the sensor, you can see that 4K output is not listed.ДЄt this point compliments to GitUp and SJCAM as they integrated an 4K option to their cameras, but never advertised them as 4K camera furthermoreВ indicate that 4K resolution is interpolated.

Good exampleВ is theВ very common 16 MP SonyВ IMX206 sensor used in Git2, YI Action Camera 1 & SJCAM M20. Their latest version Mk IV crops the output source, which looks like zooming into the frame.Д®ven if the sensor offers more than 8MP it might not be capable of 4K resolution. take the Canon 5D DSLR: with their first HD recording version, the Mk II, they binned (downscaled) the sensor output. Cameras with larger sensors will benefit from a higher photo resolution. If you crop top & bottom of a 12 MP sensor to get to aВ 16:9 format, you will end up with the 8MP for 4K resolution. Why are there 12MP sensors? ItвЂ™s more than needed fro 4K? As explained above also the photo is resized from the 4MP sensor! Therefore check the sensor type. The EKEN H9 is sometimes advertised as 12MP camera, but just the max. Same applies to the Aptina ONВ AR0330 sensor.Д«e aware, often cameras are advertised as 12 MP cameras, but the Megapixel just refer to the max. take the EKEN H9 which has a 4MP sensor (Omnivision 4689), but is branded 4K. Which means if the sensor is smaller than 8MP, you canвЂ™t get a 4K video out of it. Nevertheless if you multiply the pixels youвЂ™ll get a result of about 8,8 MP (4K) or 8,29 Megapixel (UHDTV). The 16:9 format (3840 x 2160 pixels) is called UHDTV (Ultra HD). When there should be motion but 2 frames show the exact image, the frame was doubled.Д¤K resolutions is 4096 x 2160 pixels and is actually not 16:9. You canвЂ™t tell from specs when browsing them, only when looking through your footage frame by frame. The output file now shows 30fps, but it looks like 15 fps. 15 frames per second are recorded and each frame is doubled. HereвЂ™s an example of a 10fps 4K video, recorded with an EKEN H9 and an earlyВ firmware:ДЄs mentioned at the beginning there is another trick: Doubling frames. If it is less than 24fps it will be less fluent, more likely a stop motion video. Watch out which frame rate the camera can do in 4K. So how can you check if it is a real, native 4K camera? Frame Rate If the sensor / processor is not capable of doing 4K at a reasonable frame rate, the frames are doubled to state a better figure on paper. In other words the sensorвЂ™s output is a lower resolution than 4K and then the image is upscaled by interpolation. ThisВ process works by guessing or вЂњinterpolatingвЂќ values based on a weighted average of known pixels in the vicinity. Upscaling uses known pixel values to estimate unknown intermediate pixels. Therefore the original source at a lower resolution is upscaled to achieve a 4K output file. Real 4K or nativeВ 4K is simply explained: the original source (sensor output)В is 4K resolution.ДЄs mentioned at the beginning, вЂњ4K camerasвЂќ sell better. Find out about the difference about real vs fake 4k: Although their outputВ video size is 4K, it might not be real 4K.

Simple reason, they sell better wearing this logo. There are a lot of action cameras branded вЂњ4K cameraвЂќ.
