![]() ![]() You know the 'speed' with the frame rate (1 frame per second, 10 frames per second, 30, etc.), but how many frames do you need for reliable capture?Ī person walking at a leisurely pace covers ~4 feet per second, walking across this 20' wide FoV in ~5 seconds:įor a person running, our subject goes through the 20' FOV in ~1.5 seconds, meaning he covers ~16' in just one second:įor example, if you only have 1 frame per second, a person can easily move 4 to 16 feet in that time frame. The faster an object moves, the more likely you are to miss an action. Average Frame Rates used: What is the industry average?Īs a precursor, you need to know the speed of objects, most typically people.Bandwidth vs Frame Rate: How much does bandwidth rise with increases in frame rate?. ![]() Shutter speed vs Frame Rate: How are these two related?.Playing Cards: What do you miss capturing cards being dealt at 1, 10 and 30FPS?.Head Turning: How many more clear head shots do you get of a person at 1, 10 and 30FPS?.Running: What do you have capturing a person running at 1, 10 and 30FPS?.Walking: What risks do you have capturing a person walking at 1, 10 and 30FPS?.What speed do people move and how does that compare to frame rates?.SxS memory cards can be read by laptops with an Expresscard /34 slot, or via a Sony SBAC-US20 (USB3.0) reader.įor copying your valuable recorded material it’s recommended to use software like Hedge for Mac, YoYottaID, Silverstack or ShotPut Pro that will help copy files to one or several destinations and perform a checksum calculation, comparing the material on the original media to the copies, to provide a minimum effort safety check of data integrity.Choosing the right frame rate for your application is important but understanding when you should use 10 or 15 or 20 or 30 or even 60 frames per second can be unclear. Data Managementįor transferring recorded material from a XR Capture Drive to external hard drives we offer the Codex Capture Drive Single Dock which you connect via USB3.0 to a Macbook Pro with a native USB3.0 port. With the help of an SxS Adapter into the ALEXA XR Module you can still use the now familiar SxS Pro Cards. ** Go to Recording Media for more specific frame rate and recording format information.Ĭodex XR Capture Drives are reliable high quality 512GB (480GB usable) solid-state media in a small form factor, which are able to record 16:9 ARRIRAW at up to 120fps. * Open Gate ARRIRAW is only possible on (re-calibrated & original) Alexa XT camera’s, not on XR module upgraded camera’s.
