Blackmagic Design URSA Mini series Installations- Und Bedienungsanleitung Seite 40

TIP Sometimes in extremely cold weather conditions, for example 0–5º Celsius and
32–41º Fahrenheit, URSA Mini 4K may take up to thirty seconds to reach optimal
running temperature. During this time you can record if you need to, but we
recommend waiting for your camera to warm up and stabilize. When optimal running
temperature is achieved, your camera will recalibrate to compensate for the sensor's
temperature change and you may notice a single white flash frame. This will only occur
while not recording and will improve your results when shooting in cold climates.
Record Duration Table
Tables are provided showing approximate record duration in minutes and seconds relative
to format, project frame rate and media size. The maximum recording duration for your storage
media depends on its capacity, the recording format and the frame rate. For example, the
storage rate for Apple ProRes 422 HQ at 3840 x 2160 is approximately 880 Mbps. At 24 frames
per second, you can record approximately 47 minutes of video on a 256GB CFast 2.0 or SD
card. At the same settings you can record approximately 23 minutes of video on a 128GB CFast
2.0 or SD card, which is approximately half the record duration of the 256GB card. These
durations are also the same for when recording to SSDs using the URSA Mini SSD Recorder.
It should be noted that record duration on CFast 2.0 and SD cards can also vary slightly
between cards from different manufacturers. It can also vary depending on whether the storage
media is formatted as exFAT or Mac OS X Extended.
Simple scenes containing less detail tend to require less data than more dense compositions.
The values in these tables assume shots with a high complexity, which means you may get
slightly longer record times depending on the nature of your shoot.
