hello im using this to get frame from the vid {} placeholder for variables. -i {0} -ss 00:{1}:{2} -f image2 -vframes 1 -vf scale=853:480 {1}_{2}.png How can i get the subtitles to show on the output image. The input mkv video has subtitles embeded in it but i would also like to know how to do it if it wasnt the case.
