I saw behind-the-scenes of a 4K movie restoration — and it's made me appreciate the quality of my 4K Blu-rays more than ever now I understand the 'ethical dilemmas' and artistry involved

4K Blu-ray is a big part of my work at TechRadar. Not only is it my staple source for testing the best TVs and best soundbars, but thanks to its superior picture and audio quality over 4K streaming, the movies themselves have now become one of my main areas of coverage.

As a big fan of 4K Blu-ray, both as a user in AV testing and as a collector, I helped start our Blu-ray Bounty series, where we review the latest 4K releases from each month, scrutinizing their picture and audio quality, back in 2024.
