A Hinglish SRT file is a subtitle file where Hindi is written in Roman letters and English words stay in English, exactly as you spoke them: "Aaj ka video beginners ke liye hai", not "आज का वीडियो beginners के लिए है". If you searched for a Hinglish SRT file generator, you may have noticed that free tools often give you the second version.
You can still get a clean Roman-script Hinglish .srt for free. It takes one of four routes, plus some editing. This guide walks through each one, shows what a correct SRT looks like, and covers the checks to run before you upload it.
One thing upfront. The CapsAI caption generator writes Roman Hinglish captions, but it exports an MP4 with the captions burned in. It does not export SRT, VTT or any other subtitle file. So the methods below use YouTube Studio, Whisper or your own typing, plus two free CapsAI browser tools that format and shift an SRT you make yourself. The last section explains when you can skip the SRT file completely.
What a Hinglish SRT file looks like
An SRT (SubRip) file is plain text. It holds a list of numbered cues, and each cue tells the player what to show and when. Here is one cue from a Hinglish SRT:
| Part of the cue | Example | What it does |
|---|---|---|
| Cue number | 1 | Counts up from 1, one number per cue |
| Timing line | 00:00:01,200 --> 00:00:03,800 | Start and end time, with a comma before the milliseconds |
| Text | Aaj ka video beginners ke liye hai | One or two lines of Roman Hinglish |
| Blank line | (empty) | Ends the cue so the next one can start |
There is nothing Hinglish about the format itself. A file is a Hinglish SRT because of the text lines inside it. That is why you can start from a Hindi SRT and turn it into Hinglish without touching a single timestamp. For the full format rules, see our guide on how to create an SRT file from plain text.
4 free ways to make a Hinglish SRT file
| Method | What you get first | Work to reach Roman Hinglish | Best for |
|---|---|---|---|
| YouTube Studio auto captions | Hindi captions, often in Devanagari | High: most lines need converting | Videos you are posting on YouTube anyway |
| YouTube Studio auto-sync | Your own text, timed by YouTube | Low, if you already have the text | Scripted videos and voiceovers |
| OpenAI Whisper | An SRT in Devanagari or English | Medium to high | People comfortable with Python or Colab |
| Type it yourself, then build the SRT | Your exact Roman Hinglish | Timing is the main work | Clips of a minute or two |
All four cost nothing. Neither automatic route reliably writes Roman-script Hinglish on its own, so plan for some editing whichever one you pick.
Method 1: YouTube Studio auto captions, then convert to Hinglish
If the video is going on YouTube, its automatic captions are free and Hindi is a supported language. The catch is the script. YouTube's help page does not say which script Hindi auto captions use, but in practice they are often in Devanagari, and English words you spoke may be spelled out in Hindi script too.
- Upload the video to YouTube.
- In the video's details, under Show more, set the video language to Hindi.
- Wait for the automatic track. YouTube says captions may not be ready right after upload. Its help page also lists poor audio, a long silence at the start, and overlapping speakers or several languages at the same time as reasons they may not appear. Hinglish mixes two languages, so this can affect you.
- In YouTube Studio, open Subtitles, pick the video, select Edit next to the language, then choose Duplicate and edit on the automatic track. YouTube saves your changes as a new caption track.
- Fix the text. You can retype lines into Roman Hinglish here, or download first and convert the text in one go (see the conversion section below).
- Open Options and choose Download subtitles. If you are offered a choice of formats, pick .srt.
You keep YouTube's timings and change only the words.
Method 2: YouTube Studio auto-sync with your own Roman Hinglish text
If you recorded from a script, or you already typed out what you said, YouTube can try to add the timings for you. When the text already exists and auto-sync accepts it, this can save you the most work.
- In YouTube Studio, open Subtitles, pick the video and add a subtitle language. For most Hinglish videos that is Hindi.
- Choose Auto-sync, then enter your Roman Hinglish text or upload it as a transcript file.
- Save and close. YouTube says setting the timings can take a few minutes.
- Play the video and check the timings, then download the track as in Method 1.
Be realistic about this one. YouTube's help page says the transcript must be in the same language that is spoken in the video, and it does not say whether Roman-script Hindi counts. Treat it as an experiment: if the timings come back wrong or the track fails, move to Method 4. YouTube also does not recommend transcripts for videos over an hour long or with poor audio.
Method 3: OpenAI Whisper on your computer or in Colab
Whisper is OpenAI's open-source speech recognition model. Its code and model weights are released under the MIT licence, so the software is free to use. It can write SRT files directly, so it does the timing for you, but it needs some setup.
What you need: Python, the openai-whisper package, and ffmpeg installed on your system. If your laptop has no good graphics card, you can run it in a Google Colab notebook instead. Colab is free to use, though Google says free access to GPUs is heavily restricted.
A typical command looks like this: whisper myvideo.mp4 --model turbo --language Hindi --output_format srt
A few things to know before you run it:
- Expect Devanagari. With the language set to Hindi, Whisper usually writes Hindi words in Devanagari. You will still need the conversion step below.
- Translate mode will not give you Hinglish. The translate task turns speech into English, and Whisper's own README says the turbo model is not trained for translation.
- Shorter cues are possible. Add --word_timestamps True and --max_words_per_line 6 to keep each cue short enough for a phone screen. Whisper marks word timestamps as experimental, so check the timings.
- Prompts are only hints. You can pass a Roman Hinglish sentence with --initial_prompt to nudge the spelling style. By default it only applies to the first window of audio, it is not a setting, and it may not change the script, so check the output.
- Speed depends on your hardware. Whisper's README lists about 6 GB of video memory for the turbo model. On a basic laptop without a GPU, it can be slow.
Method 4: Type it yourself, then build the SRT
For a 30 to 90 second Reel, typing is often faster than fixing a machine draft. You control every spelling, and there is no script conversion at all.
- Play the video and type what you say in Roman Hinglish, one short caption per line.
- Paste the lines into the free TXT to SRT converter. Choose how many seconds each cue stays on screen, and it builds a numbered SRT draft with timestamps.
- The draft gives every line the same duration, so it will not match your speech yet. Open it next to the video and adjust each start and end time. Any plain text editor works.
- If every cue is early or late by the same amount, shift them all at once with the subtitle timing fixer instead of editing each one.
How to convert a Hindi SRT into Roman Hinglish
The Hindi to Hinglish captions guide covers this step in more depth, with transliteration examples. In short:
Methods 1 and 3 usually leave you with a Devanagari SRT. The rule for converting it is simple: change only the text lines. Leave the cue numbers and timing lines exactly as they are.
You have three practical options:
- Retype the lines. Slow, but you get natural spelling. Fine for short videos.
- Use a transliteration tool. Fast, but many tools follow formal schemes built for precision, not for social media. The result can have accent marks and spellings people rarely type on WhatsApp.
- Ask a general AI chatbot. Paste the SRT and ask it to rewrite only the text lines in Roman Hinglish, keeping numbers and timestamps unchanged. Then check that the cue count and the first and last timestamps still match the original file.
Here is why the review step matters, whichever option you use:
| Devanagari draft (example) | Strict transliteration | Natural Roman Hinglish |
|---|---|---|
| आज का वीडियो beginners के लिए है | āja kā vīḍiyo beginners ke lie hai | Aaj ka video beginners ke liye hai |
| प्राइस सिर्फ 499 रुपीज़ है | prāisa sirpha 499 rupīza hai | Price sirf ₹499 hai |
| मुझे ये फीचर काफी यूज़फुल लगा | mujhe ye phīcara kāphī yūzaphula lagā | Mujhe ye feature kaafi useful laga |
The biggest problem is English words written in Devanagari, like प्राइस for "price". A transliteration tool turns them into odd spellings, and only a careful read puts them back as normal English. While you are at it, pick one spelling for common words, such as hai, nahi, kya and bhi, and keep it the same across the whole file. If you are unsure which script suits your audience, our guide on native script vs Roman script explains the trade-offs.
Hinglish SRT checks before you upload
Run through this list before you upload the file to YouTube or import it into an editor:
- Save as UTF-8. YouTube asks for SRT files in plain UTF-8. Other encodings can break the ₹ sign and any Devanagari left in the file.
- Comma before milliseconds. 00:00:01,200 is correct. 00:00:01.200 is the WebVTT style, and some players reject it in an SRT.
- One or two lines per cue. Around 42 characters per line is a common guideline for landscape video. For vertical video, shorter is better.
- Give each cue enough time. A cue that flashes for less than a second is hard to read on a phone.
- No overlaps. Each cue should end before the next one starts.
- Plain text only. YouTube supports only basic SRT with no style markup, so colours and fonts written into the file will not show there.
When you do not need a Hinglish SRT file
An SRT is a sidecar file. It sits next to the video, the platform shows it as closed captions, and viewers can switch it off. That is useful for long YouTube videos, course platforms and editing software that imports subtitle files. It is often not what a Reels or Shorts creator needs.
For short-form videos, the common alternative is to burn the captions in, so the text is part of the picture. When you share that MP4 to Instagram, YouTube Shorts, WhatsApp or Moj, the captions go with it, and you decide the font, colour, size and position. A separate SRT file does not travel with the video when you share it. Our guide on burned-in captions vs closed captions compares the two in detail.
Burned-in Hinglish captions are the job the CapsAI Hinglish caption generator is built for:
- Select Hinglish, then upload an MP4 or MOV of up to 10 minutes from your phone or desktop browser.
- You get timed captions in Roman script, with English words kept as you spoke them.
- Edit any word or timing, then pick from 35 animated caption styles.
- Export an MP4 with the captions burned in.
To repeat the important part: the caption generator does not give you an SRT or VTT file. For a sidecar caption file, use the free methods above.
Which method should you pick?
- Your video is on YouTube and you want closed captions: Method 1, then convert the text.
- You have a script or a typed transcript: Method 2, or Method 4 if auto-sync fails.
- You are comfortable with code and have many videos: Method 3.
- It is a short Reel and you only need on-screen captions: skip the SRT and burn the captions in.
