Quality of SRT styled open caption when burnt into video
When importing an SRT in as an open caption and styling this, to then be burnt into a video, the output of the caption overlay is not of a high quality. There are harsh/jagged edges around the letters. A current workaround is to import the caption at a much larger font (e.g. 100), and then use a motion effect to downscale the whole caption size much further down in order to minimises the harsh edges.
