Disabled by default.
``--image-subs-video-resolution=<yes|no>``
Override the image subtitle resolution with the video resolution
(default: no). Normally, the subtitle canvas is fit into the video canvas
(e.g. letterboxed). Setting this option uses the video size as subtitle
canvas size. Can be useful to test broken subtitles, which often happen
when the video was trancoded, while attempting to keep the old subtitles.
``--sub-ass``, ``--no-sub-ass``
Render ASS subtitles natively (enabled by default).
