A video becomes subtitles in three basic steps: transcribe the speech, review the transcript while playing the video, then export a subtitle file such as SRT or VTT. On Mac, Jotr gives you this workflow for existing video files, including MP4, MOV, MKV, and AVI, and lets you start free transcription without an account or credit card.
What you need before making subtitles
Before you can create subtitles, your video needs a transcript. An SRT or VTT file is not just the video itself converted into another format. It is a text-based subtitle file that contains the spoken words and timing information, so each caption appears at the right moment during playback.
That means the practical workflow is:
- Import the video file.
- Transcribe the speech.
- Review and clean up the transcript.
- Export the result as SRT or VTT.
This matters because raw transcription is only the first pass. If you want subtitles that are useful for publishing, teaching, editing, or sharing, you usually need to check names, technical terms, sentence breaks, and timing against the actual video.
Step 1: Import your existing video file
Start with the video file already saved on your Mac. Jotr works from existing audio and video files, not live dictation or YouTube URL scraping.
Current video imports include:
- MP4
- MOV
- MKV
- AVI
For many Mac users, this covers the common files they already have from screen recordings, cameras, video calls, interviews, lectures, podcasts, and editing exports.
Once the video is imported, Jotr creates, stores, and processes the project on your Mac. There is no account system, no cloud workspace, and no app backend for user work.
If your first goal is a transcript rather than subtitle files, use the broader guide to transcribe video to text on Mac.
Step 2: Transcribe the video speech
After importing the file, transcribe the video. This creates the text that will become your subtitle or caption file.
If your goal is to turn MP4 to SRT, export transcript to VTT, or create a WebVTT caption file for a website, this transcription step is required. SRT and VTT files are outputs from the transcript workflow. They are not the first thing you create.
At this stage, do not worry about making every line perfect before you have reviewed it. The first job is to get the speech into text with timestamps so you can work from it.
Step 3: Review the transcript against playback
Subtitles are easier to use when the transcript has been checked against the video. Jotr lets you review transcripts with timestamp-linked playback, so you can move between the text and the matching moment in the recording.
This is useful when you need to:
- Fix misheard names or terms.
- Clean up punctuation.
- Remove obvious false starts if they do not belong in the subtitle file.
- Check whether a line makes sense when seen on screen.
- Make the transcript easier to follow for viewers.
For creators, this review step can make the difference between a rough transcript and a usable caption file. For educators, interviewers, podcasters, and professionals, it helps turn a recording into something easier to search, share, quote, or repurpose.
This review-first export layer sits inside Jotr’s broader AI transcript review, notes, and export workflow.
Step 4: Export SRT or VTT subtitle files
When the transcript is ready, export it in the format you need.
Jotr raw transcript exports include:
- Plain Text
- SRT
- VTT
Jotr reviewed transcript exports include:
- Plain Text
- Timestamped text
- SRT
- VTT
- Markdown
- Timestamped Markdown
- Word/DOCX
- Timestamped Word/DOCX
For subtitles, the two main formats are SRT and VTT.
SRT is widely used for subtitle files in many video workflows. VTT, also called WebVTT, is commonly used for web captions and HTML video players. If a platform asks for a subtitle file, caption file, SRT file, or VTT file, this is the export step you are looking for.
If your source is specifically an MP4, the MP4 to SRT on Mac guide covers that narrower path.
SRT vs VTT: which should you choose?
Choose SRT if your video platform, editor, or publishing tool asks for an .srt file. It is a common subtitle format and is often a practical first choice when the destination does not specify WebVTT.
Choose VTT if your website, web video player, or publishing workflow asks for .vtt or WebVTT. VTT is designed for web caption use and is often the format expected in browser-based playback.
If you are not sure, check where you plan to upload or use the subtitles. The destination usually tells you which file type it accepts.
What Jotr does and does not do
Jotr helps you turn existing video files into transcripts and export subtitle files such as SRT and VTT. It is a transcription review workspace for Mac, not a full video editor.
That distinction matters. Jotr exports subtitle files; it does not burn styled captions into the video. If you need permanent, designed captions visually embedded into the video image, you would export the SRT or VTT from Jotr and use that file in a separate video editing or publishing workflow.
Jotr is also not an online converter and does not work by scraping YouTube URLs. The workflow starts with a file you already have on your Mac.

A simple Mac workflow for video to subtitles
Here is the practical version:
- Save your video file on your Mac.
- Import the MP4, MOV, MKV, or AVI file into Jotr.
- Transcribe the speech.
- Review the transcript with timestamp-linked playback.
- Export SRT or VTT.
- Upload or use the subtitle file wherever your video will be published.
This is the cleanest way to go from video to subtitles without turning the process into a tool hunt. You start with the recording, create a transcript, check it, then export the caption file you need.
