Autoframerate, sometimes abbreviated as AFR, is the automatic adjustment of the frequency of the TV screen to the frequency of the video being played. If the screen refresh rate matches the movie or video, the image, especially in landscape and dynamic scenes, will be smoother. If this frequency does not match, twitches or a “stepped” image may appear when the camera moves. Auto Frame Rate matches the screen refresh to the frame rate of the video, switching the TV automatically.
Video frame rate
Most TV channels in Europe are broadcast at 25 or 50 frames per second. In the USA, the standard system is adopted – 30 or 60 frames per second for television. Most modern TVs are available with a choice of screen refresh rates – 50 or 60 Hertz, which is in line with global television standards. But there is a slight discrepancy with the films that are made for cinema. The standard screen refresh rate is 24 frames per second. There are also movies shot at 23.97 frames per second. When broadcasting movies through a TV channel, the provider uses various algorithms to smooth the picture and match frames. If you watch a movie from the Internet via Tv Box, the video is displayed on the TV screen with the original frame rate. So this is the picture:
Scatter 24 fps at 60 fps – Refreshes the TV screen.
It turns out that one original frame of the film is shown either 2 times or 3 times. This results in twitching in the image in large scenes. There is no smoothness and continuity of the picture as a whole.
How autoframerate works
When you open any video – a movie, TV channel or video on YouTube, Tv Box understands how often the playback will be. Auto Frame Rate will automatically switch the TV screen according to the video file. When you open a movie or TV channel, the TV will turn dark for a second – and then the movie or channel will start at the original frequency. Of course, you can manually rearrange the screen updates each time with the TV remote control. But it’s much easier to do it yourself Tv Box, without any extra effort.

A huge mass of various Tv Boxes are sold in online stores and Chinese sites. Not all models have a built-in autoframe.
