Recently, I needed to merge some mp4 files and srt files. If you only need to merge, it is very easy way you have. That is to use MP4Box. But I needed a hardcord subtitle version this time. I think MP4Box cannot give this type. Am I right? Anyway I couldn’t create a mp4 file with a hardcord subtitle by MP4Box, so I was searching for information and found this out on YouTube. It’s very nice. But, this time I had mp4 files more than twenty and have to set this about each mp4 file if I use VLC GUI. It’s very inconvenient. So I wrote a batch file as below.
