How long will your card or SSD last? Choose the ProRes codec, frame size and frame rate and see the recording time. Or enter how long you need to record and get the capacity to buy.
Hours and minutes.
Capacity is in decimal gigabytes, as printed on the card. ProRes is variable bit rate, so real files can be a little smaller or larger than these Apple target rates: leave some headroom.
Recording time is a division: the capacity of the card divided by the data rate of the codec you record in. This calculator uses the target data rates Apple publishes for every ProRes flavour, frame size and frame rate, adds the audio you are recording, and does the arithmetic for you, in both directions.
Frame size and frame rate multiply the data: UHD carries four times the pixels of HD, and 50p carries twice the frames of 25p. The codec then sets how hard each frame is compressed, from ProRes 422 Proxy at the small end up to ProRes 4444 XQ. Switching a 1080p25 recording from ProRes 422 HQ to ProRes 422 LT, for example, roughly halves the space it needs. The table next to the result shows every codec for your chosen format at once.
Embedded audio is uncompressed PCM. At 24-bit and 48 kHz each channel adds 1.152 Mb/s, so a 16-channel recording adds about 18 Mb/s. Small next to video, but it adds up on long events.
Card makers count in decimal gigabytes (1 GB = 1,000,000,000 bytes), and so does this calculator. Your computer may show the same card as a smaller number in binary units (GiB), and the file system takes a small share too. That is why a 512 GB card never gives you exactly 512 GB of footage.
Only ProRes is included for now, because Apple publishes exact figures for it. Which codecs, frame sizes and media a particular HyperDeck can record depends on the model, so check your model's specification before planning a shoot around a setting.

At 1920 × 1080 and 25p, ProRes 422 HQ is about 184 Mb/s for the video, which with two audio channels comes to roughly 6 hours on a 512 GB card. At UHD 25p the same codec is about 737 Mb/s, so the same card holds about 1.5 hours.
ProRes is a variable bit rate codec: simple pictures need fewer bits than detailed ones. Apple's figures are targets, so real recordings of calm, clean pictures can come out smaller, and noisy or very detailed ones larger. Plan with a margin.
Yes. The data rates belong to the codec, not to the recorder, so the numbers apply to any device that records ProRes at the same frame size and rate. What differs is which settings each device supports.
Interlaced formats record the same amount of data as progressive at half the rate, so 50i uses the 25p row and 59.94i uses the 29.97/30p row, as in Apple's own table.
No. Everything is calculated in your browser. The only thing we count is that the tool was used, with no personal details.
