Hi, Eyad, the subtitles file is very small compared with the video file. After choosing the output format, you can click the "Settings" button to adjust the bit rate, frame rate, resolution, etc. exactly as the original file. In this way, the output file won't increase too much of your video size. Hope it works for you. Best regards,
how do I do that ?
well hey I have a question, I only want to merge the subtitle with the video.. I don't wanna increase the size of the video... that's it
