4K

4K – Currently the most popular of the higher resolution in digital cinematography and film. The term 4K refers to the horizontal resolution of these formats, which are all on the order of 4,000 pixels. Historically many aspects of handling 4K have been problematical – not least due to the large data rate (over 1.1 GB/s) and the amount of data produced – about 4 TB/h. However modern technologies applied all the way from scene to screen have now made 4K far more readily accessible. For some time, 4K has been the format of choice for some complex effects shots where it was felt these needed extra quality (over 2K) to still look good after all the necessary processes are completed, specially where the finished shots are inter-cut with the original camera data. Now it is increasingly being used for entire movies.
