Screen resolution is an index of pixels displayed on the screen and is often called pixels. The larger these indicators, the more detailed the display will be.

Besides resolution, frame rate is also one of the most common factors related to smartphone video recording standards that users need most concerned about.

The frame rate of video when recording is denoted as FPS (frame per second) which is the quantity of the number of frames that appear in one second of the video. The higher the FPS, the smoother the image. For example: a smartphone camera when shooting movies at a rate of 30 FPS, this means that every 30 seconds will be captured by the camera, then when the video is played back, 30 images have been recorded. Previously, it was displayed very quickly on the screen in just 1 second, giving the human eye the image of continuous transition.

All videos recorded at 60 FPS or more can be turned into slow motion scenes. If your phone can record video at 120 FPS or 240 FPS, it will also have a way to slow down the scene for you. In other words, if you shoot a video at 120 FPS, the scenes will be slowed five times and that will be 10 times if the video is recorded at 240 FPS.

Today, some commercial smartphones integrate the fastest frame rate up to 960 fps. With this speed, ultra-slow footage gives users more interesting moments than usual.
