Modern TVs have many picture modes that are designed to enhance your watching experience depending on the type of content you watch on your TV.
One such mode that is available on some televisions is True Cinema, which is designed to provide a better movie watching experience.
How does a True Cinema mode work
It’s no secret that most movies are shot in 24p, but most TV shows movies in 30p or 60p, adding extra frames. Sometimes this works well and you may not even notice the difference, but sometimes the difference becomes noticeable and the extra frames create a blurring effect, especially in active scenes.
True Cinema mode attempts to determine the original frame rate and use that, without adding artificial ones. This does not mean that everything is displayed as in the original recording, the frame rate can be adjusted slightly to improve the viewing experience.
However, this mode reduces brightness, so some people do not recommend using it. My opinion is that this mode is great for watching movies, series and TV shows because it avoids the judder effect.
An example of True Cinema
Let’s imagine a random movie shot in 24 frames. Most TVs now play such movies in 60p. It would seem that the way out is obvious – just show each frame several times and you will get the same picture quality. However, there is one problem – you cannot divide 60 by 24 to get an integer.
That means that some frames will be repeated 2 times while others will be repeated 3 times. This causes a judder effect where you feel that the image is not quite smooth. And it is! Because some scenes last 3 frames while others last only 2.
True Cinema (depending on the specific technology) smooths out this feeling by making all frames are shown the same amount of time. This makes the images seem smoother. However, don’t confuse this with the soap opera effect, they’re completely different.
