Where, in other words, the repetitive nature of the sky makes heavier compression temporarily possible without causing obvious artefacting.Īlthough the transfer’s HDR and expanded colour work isn’t as aggressively, immediately stellar as its 4K clarity, it still plays its part in creating the film’s all-important realism. The only time the datarate drops as low as 40-50Mbps (still quite high by the standards of some 4K Blu-rays) is with shots that contain a lot of monotone sky. During scenes that contain a lot of background detail and movement data rates routinely exceed 80Mpbs, punching right up to 100Mbps at times. It likely does no harm to the extreme detail and clarity of the picture that the transfer runs at a very high bit-rate. The 1917 4K Blu-ray's HDR really springs to life with the ruined town at night sequence. The lack of general fizzing noise during these ultra-dark moments is also remarkable - and testament again to the high resolution of the master. There’s always enough detail visible to make the blackness feel authentic rather than like any sort of hollow ‘cheat’ in the filming or mastering process. There’s no sign of the compression artefacts and noise that were so noticeable in the dark moorland and chapel scenes towards the end of Sam Mendes’ Skyfall 4K Blu-ray ( reviewed here), either.īlack levels go extremely deep, but never to an unnatural, forced degree. It never slides into softness, even during the film’s occasionally ultra-dark sequences, such as the one where Schofield meets the lady looking after the baby beneath the ruined occupied town. The consistency of the detailing is another huge factor in 1917 qualifying as a, if no THE, reference grade 4K Blu-ray disc. It also adds to the impact and immediacy of a film that’s all about trying to recreate for the audience the actual experience of being at war in 1917. After all, here it doesn’t just make the picture quality objectively better. In this respect, in fact, 1917 arguably delivers the single most compelling proof yet of just how important 4K is. What’s more, this lifelike sharpness applies equally to foreground and background image elements, combining with the long, seemingly cut-free shots to create a mesmerising feeling of ‘being there’.

The detail and depth in this shot is something to behold in 4K.
