Most people were extremely satisfied when codec H.264 was released, because it allowed compression that managed to fit greater resolution and high FPS files into lower Mbps files in comparison to even older codec types. The compression result is also affected by the amount of details and scene that is being recorded. If the same video was recorded in 4k quality (2160p) in 120FPS and was excessively compressed to fit into 5Mbps file, then certain (if not most) of the details would be distorted, pixelated or simply indescribable. For example, if a 720p video recorded in 24FPS is compressed into 5Mbps file, the overall quality of it will be acceptable because the codec correctly compresses the file. It attempts to compress the video so that it fits in a specified amount of Mbps file. The codecs used in the process of video making play an important part when it comes to final video quality. Correlation between resolution, FPS, and bitrates It directly affects the quality of a video as well as its size. Most of the time, those are measured in megabits (Mbps) or kilobits (kbps). So what exactly is bitrate in a first place? Bitrate is the amount of data needed to encode a video within given timeframe (usually within one second). While there are many simple options such as “frames per second” or “video resolution”, it might still be possible to record a video with horrible quality if bitrate, which works completely independently from the former two, is set to minimal value. Whether it’s recording new videos or editing existing ones, it is important to remember about setting up the software so the final video looks in desired way.
