I am using ASS/SSA format for hard coding captions on the video. These are relevant parts of my .ass file:
Format: Name, Fontname, Fontsize, PrimaryColour, SecondaryColour, OutlineColour, BackColour, Bold, Italic, Underline, StrikeOut, ScaleX, ScaleY, Spacing, Angle, BorderStyle, Outline, Shadow, Alignment, MarginL, MarginR, MarginV, Encoding
Style: s0, Montserrat-Black, 60, &H0015CCFA, &H001C1CB9, &H77000000, &H00000000, 1, 0, 0, 0, 100, 100, , 0, 1, 2, 2 , 2, 0, 0, 0, 1
[Events]
Format: Start, End, Style, Text

And to hard code on the video, I use following ffmpeg command:
ffmpeg -i video_filepath -vf ass={ass_filepath} -c:a copy -y out_path
This works as intended, except the captions are highly antialiased.
