Can MP4 have embedded subtitles?
Yes, subtitles can be embedded in MP4 videos. As opposed to being kept in a separate file like SRT or VTT, the subtitle information is now immediately incorporated into the video file. While you can also add SRT files to MP4 at all times, on video players that support them, embedded subtitles can be viewed without an external subtitle file. This is a practical way to add subtitles to your MP4 videos because it is supported by many contemporary video players and streaming providers.
How do I create a SRT file for MP4?
To create an SRT file for your MP4 video, create a new text file and save it with a .srt file extension. Add the subtitle index number, start and end timecodes, and subtitle text for each subtitle. Once done, you can add the SRT file to your MP4 video using a video editing software or an online subtitle editor. However, you can also choose to auto-generate and add subtitles to MP4 online with a tool like Flixier.
Can you add subtitles in MP4?
Yes, you can add subtitles to MP4 videos using Flixier's online subtitle editor. You can easily add subtitles to MP4 free with just a few clicks, without the need for any software installation. Adding subtitles can make your videos more accessible and enjoyable for a wider audience.
