ffmpeg subtitles alignment and position

Question

I am adding subtitles to a video using:

ffmpeg -i \"imput.mp4\" -lavfi \"subtitles=subtitles.srt:force_style=\'OutlineColour=&H100000000,BorderStyle=3,Outlin         


        

Answer 1

I try to small size the text and turn the margin of bottom: Alignment=2, Fontsize = 5, MarginV = 1 It's work for me. like this way:

ffmpeg -i "1.mkv" -lavfi "subtitles=1.srt:force_style='Alignment=2,OutlineColour=&H100000000,BorderStyle=3,Outline=1,Shadow=0,Fontsize= 12,MarginV=35'" -crf 1 -c:a copy  -vcodec h264_nvenc  "output.mkv"

*-vcodec h264_nvenc is cuda accelerator.
