How they lie:
1. Fake 4K "video-picture". The recorded resolution is 3840x2160 but the video is obtained by 10 or 15 consecutive photos/second and by adding a PCM audio so you will watch a picture slideshow with sound. The quality is much much worse than next category, fake 4K resized.
Usually these cameras price is about $60 and overall quality is bad, no firmware support, avoid these cameras because their goal is low price.
Eken H9 4K original video download, thanks to
@Pavle .
After analyzing the video with Mediainfo people should know that the video is obtained from JPEG pictures, there is no video codec used to create a Heken H9 „video”.
The FPS is low because the chipset can not create at least 24 JPEG consecutive pictures in one second.
So when you are watching a Eken H9 4K video in fact you are looking at a very fast pictures slideshow with audio. They are using this trick because chipset and/or image sensor is not supporting 4K video.
Here is a part of mediainfo information and with italic font I wrote my comments:
Video
Format :
JPEG - picture, not video ( here must be AVC or HEVC for a 4K video)
Codec ID :
jpeg - picture, not video (here must be something like avc1 or hvc1 for a 4K video
Bit rate : 49.1 Mbps
(50mbps for such poor quality is wased space)
Width : 3 840 pixels
(OK)
Height : 2 160 pixels
(OK)
Original height : 4 320 pixels
(original height captured by sensor but downsized to 2160 to match 4K resolution and obtain 16:9 aspect ratio)
Display aspect ratio : 16:9
(OK)
Frame rate : 10.000 fps
(real 4K should be over 24fps)
Do you think that a real 4K is looking so bad?
