The platform's compression algorithm determines the initial video quality on Instagram. This algorithm is designed to reduce the size of the video file without losing too much quality. Instagram videos are compressed to a maximum resolution of 1080 pixels, which is lower than many other video platforms. The frame rate is also reduced to 30 frames per second, which is lower than the industry standard of 60 frames per second. In addition to the resolution and frame rate, other factors can also affect the initial video quality on Instagram. These include the bitrate and file format of the video. The bitrate determines the amount of data used to store the video.
