While it is usually close to the target data rate, the actual data rate can vary with image content.*³ The ALEXA ProRes target data rate is the Apple target data rate plus metadata and other overhead.*⁴ The remaining time indicated by the camera is always calculated based on the theoretical maximum data rate, not the target data rate, to be on the safe side.
