Sony’s FDR-AX33 Handycam Camcorder records 4K and HD movies in the XAVC S format, which uses MPEG-4 AVC/H.264 for video compression and linear PCM for audio compression, while saving files in a MP4 wrapper which allows for extensive record times and easy editing. The FDR-AX33 captures the finest details in 4k (QFHD: 3840 x 2160), 4x Full HD resolution. The XAVC S codec and incredibly high resolution produces vibrant and extremely realistic images. What’s more, the blazingly fast image processor is the same one employed in professional Sony models, making it possible to record 30p movies in 4K and 60p in Full HD 1080 resolution for incredibly smooth and sharp playback, with no loss in realism, even when panning the camera and shooting moving subjects.
