Hello i have a mp4 file and i would like to add subtitles to it, ive tried using Yamb and it completes with no error but when i play the file either on PC or PS3 the subtitles are not there. Ive also tried to do it without audio just video and subtitles and it worked (but obviously i would like it with sound). And i have another file mp4 and i tried the same thing with Yamb and it works even with audio but instead of letter Squares appear (ive checked the language_croatian at properties). With what other program can i add subs to mp4 without converting video ? Please help me.
