To play back Apple ProRes 4k. Basically, your whole system from storage to display has to support 4k.
Here's an outline of what's needed:
- 4K display
- 4K capable cable (and display interface), such as HDMI High Speed cables
- 4K capable graphics system (integrated or discreet)
- At least 8GB of system memory is recommended
- Any 4th Generation Intel Core (Haswell) processor or above should work
(Please check tech specs for your processor and graphics system on Intel or AMD's sites)
- Storage capable of 4k bit-rates (from 155Mb/s for ProRes 422 up to 4.242Gb/s for ProRes 4444)
As a quick answer, any Windows laptop with a 4k screen and SSD (flash) based storage should support playback of 4k. To support Apple ProRes codecs, you'll need to install QuickTime 7.7.9 for Windows. Apple no longer support QuickTime for Windows, so you may not be able to playback the latest codecs unless you can find an Authorised third-party ProRes product to do so (using unauthorised products to playback may lead to problems).
More on Storage
Your storage will need to be able to keep up with the target data rates, so SSD (flash) storage is a must. See page 22 of Apple’s ProRes White Paper for more specifics on bit-rates (for 4k it varies between 155Mb/s (70GB/hr) up to 4.242Gb/s (1.909TB/hr). Notice that the rates per second are in bits (small ‘b’) where as the rates per hour are in bytes (uppercase ‘B’) - for estimating storage capacity requirements. There are 8 bits per byte, so 1Gb/s is the same as 125Mb/s.
An Example Shopping List
If you want a more straight forward list of what to buy, here you go:
- 4th Gen (Haswell) Intel Core i5 or i7
- 8GB memory
- SSD storage (as Apple ProRes codecs at 4k requires a minimum of 155Mbps).
- 4k capable display port and cable (e.g., HDMI 2 cable)
- 4k capable processor and graphics system
