T2V006 Synthetic

Overview

T2V006 Synthetic and T2V016 Synth3060 have the same content: the difference is that the clips in T2V006 Synthetic are at a nominal frame rate of 25 frames per second (nominally 720p25, 1080p25 and 1080i50); whereas the clips in T2V016 Synth3060 are at nominal frame rates of 30 and 60 frames per second (720p30, 720p60, 1080p30, 1080p60 and 1080i60).

Note however that either clip set can be played at any frame rate as they are YUV uncompressed, particularly as the clips are largely synthetic with a relatively small (or no) video content

Software provided

Notes: (1) for YUV viewer software, see the list on the YUV viewers page
