Topic: Subtitle speed changer,..
Here's a small tool I wrote to change the timestamps in different subtitle formats (idx/sub, srt, ass, ttxt).
Welcome to 'SubtitleSpeedChanger'!! written by Selur subtitleSpeedChange --input "Path to subtitle file" --speed factor --delay delayMs --output "Path to output file" i.e.: subtitleSpeedChange --input "d:\InputSubtitle.idx" --speed 0.892 --delay 10 --output "Path to output file" Side notes: [*] --input "Path to subtitle file" specifies the input file [*] --speed also accepts toFPS/fromFPS; and [*] --outfps alternative to --speed causes subtitleSpeedChange to guess the fps of the input subtitle and calculate the speed with the output to match the output fps
