Frame rate

0

Frame rate shouldn’t be much of a problem unless you are trying to do a video on a lower bandwidth application. Of course, if your clinical situation is assessing a movement disorder, then the frame rate may be a significant factor. If your set up has access to a bandwidth of 384 Kbps and you are using a typical H.264 or VP9 codec, then to experience 30 frames per second you are probably limited to a resolution of CIF. The math is straight forward as an HD 720p image (1280×720 pixels) carries 24 bits of color/intensity data that refreshes at 30 frames per second. These settings would generate about 664 Mbps of data. The codec compresses this down to about 2-3 Mbps so it can be sent over the network. Higher resolutions quickly increase the amount of data being sent for each frame. Again, the clinician will need to determine whether the frame rate is impeding their ability to remove something from the differential diagnosis or not and plan.
