Will output in this format be supported someday? Looks like only way to use Dolby Vision is to use mp4 and this container is supporting only AC3 which is max 640. Support for recompression of for example DTS to EAC3 (which have much higher bitrate) would be great. Second question. When I am selecting source as AC3 and mp4 container then I don't have option for copy original audio without recompression (lossless). This option is only available for mkv. Why?
