It’s more! On X-H1, it is 200 Mbps, which is double the value. On the other hand, the successor X-T2 has a significantly higher bit rate of 100 Mbps As a result, the image quality when recording movies has improved dramatically. I think there were many single lens digital cameras in the past at around 25-50Mbps, but recently, especially high-end models, many models with high bit rates exceeding 100Mbps have been lined up.įor example, the bit rate of the FUJIFILM X-T1 is not disclosed, but it is probably between 35 and 50 Mbps. It is usually expressed in units of Mbps (megabit per second). This large amount of data means that the bit rate is high. The lower the compression, the better the image quality, but the larger the data, right? On the contrary, a large amount of data means that the compression rate is low and the image quality is good. It may be close to the compression rate of JPEG in photos. Simply put, how much data are you sending to the media per second? With the value of, the higher the data capacity, the better the image quality. Of these, I think the image size and frame rate are relatively easy to understand, but what is the “bit rate”? The higher the value, the more elements make up the video and the higher the image quality. Bit rate (100Mbps, 400Mbps, etc.) → Close to the JPEG compression rate in the photo. Frame rate (24p, 60p, etc.) → How many frames are taken per second? The more, the smoother the movement will be (it does not mean it should be smooth).ģ. Larger images (more dots (number of pixels) that make up an image) look better when viewed on a compatible monitor.Ģ. Image size (FHD, 4K, etc.) → Number of pixels in the photo. In general, I think the following three are the main factors that determine the image quality of a video.ġ. Basically the larger the size, the higher the image quality.Īctually, I didn’t understand anything at first, so I tried to summarize it briefly this time. Relationship between bit rate and video qualityĭo you know the “bit rate” when recording movies?īit rate is a value that indicates the speed of data transfer and is one of the factors that determines the image quality of video.
