How to Add English Subtitles to a Spanish Video

When you're watching a cooking lesson, you need to see the pan as well as read the subtitles. An English-speaking viewer following a Spanish recipe needs time to do both. Otherwise, they may miss the moment the sauce starts to thicken.

You can keep the Spanish voice and add an English subtitle track. You'll need the finished Spanish video and an English SRT file: the words, plus the times they appear and disappear. Adding that file as a subtitle track leaves the original audio alone.

Start with the finished Spanish video

Keep a copy of the edit you plan to publish. Cutting an introduction after you've timed the subtitles can put every line that follows out of step.

In SoulDub, upload the MP4, choose Spanish → English, and check the credit estimate before creating the task. The workflow includes dubbing as well as subtitle translation. It's particularly useful if you're preparing an English voice track alongside a Spanish version with English captions: you can review the source transcript and English translation in the same video workspace.

If you want the project to keep the original video duration, leave Use dynamic duration off. Individual timings still need review; that setting doesn't guarantee every subtitle will land exactly where you want it.

Once the result is editable, select a subtitle row to jump to that part of the video. Listen to the Spanish, compare the two texts, and check the action on screen. If an ingredient name is wrong in the transcript, correct it and check the corresponding English too. Polishing the English first can make a mistranslation sound more convincing.

For the subtitled Spanish version, you'll use the English SRT with your saved MP4. Keep the final caption wording and line breaks in that file.

Shorten the sentence without losing the instruction

Take this example from a cooking lesson:

Cuando la salsa empiece a espesar, añade la leche poco a poco y remueve sin parar.

One natural translation is:

When the sauce starts to thicken, add the milk a little at a time and keep stirring.

That's clear English. If the viewer can't finish reading it before the next instruction, try:

When the sauce starts to thicken, slowly add the milk and keep stirring.

The second version keeps the trigger—wait for the sauce to thicken—and both actions: add the milk gradually and keep stirring. “Add the milk” would be shorter still, but it would leave too much out.

An illustrative edit of the same instruction; these are example translations, not a recorded SoulDub result.

Some mistakes won't look wrong in English. Cucharadita is a teaspoon; cucharada is a tablespoon. Either sounds plausible in a recipe. Check quantities, temperatures, and ingredient names against the Spanish, with help from a Spanish speaker if needed. In an interview, give the same attention to small changes in meaning: “we might” shouldn't become “we will.”

Leave time to watch the video

Play the lesson at normal speed. After reading a caption, can you look back up and see what the cook is doing? If the next caption arrives before you can, the wording may need another cut.

Line breaks matter, too. Avoid splitting “a little at / a time” across two lines. Keep “a little at a time” together and move the next phrase down instead. Aim for one or two readable lines, then try them on a phone.

On a small screen, the subtitle should leave room to follow the cooking.

Don't leave the previous instruction on screen through the next step just to give people longer to read it. In a conversation, clear the caption when the next person takes over. SoulDub lets you adjust subtitle start and end times for the project; for captions attached to your untouched Spanish recording, make the final timing decisions against that recording.

Choose the English file, then finish the captions

In the editor's Export assets menu, start with Translated Subtitles .srt. The similarly named downloads serve different purposes:

Open the English SRT with your original Spanish MP4 in a subtitle editor. If you've edited a sentence in SoulDub, find it in the downloaded file: a draft change in the dubbing workspace may not yet be part of that export. If the old wording is still there, correct it in this SRT and save the file. You can finish these caption changes without regenerating the English voice track.

Check a line near the beginning, one in the middle, and one near the end. If all are late by the same amount, a timing offset may fix it. If the gap changes after a cut, adjust those captions individually. A dubbed result made with dynamic duration can have different scene lengths, so its converted subtitle file may not fit the original recording.

Match the captions to the video you will actually publish.

Put the subtitles where people will watch

On YouTube, upload the Spanish video, then add English as a separate subtitle track in YouTube Studio:

1. Open Subtitles and select the video.

2. Choose Add language → English, then add subtitles for that language.

3. Choose Upload file → With timing and upload your reviewed SRT.

Watch the pairing through before publishing the captions. YouTube's official instructions explain the upload options. Its Auto-sync option requires the transcript to match the language of the spoken audio, so use your timecoded English file for this Spanish recording.

If you need the words always visible, import the original MP4 and reviewed SRT into a video editor and export with the subtitles burned in. Keep them clear of the hands, ingredients, and other details viewers need. Burned-in text cannot be switched off; fixing a typo later means exporting the video again.

For viewers who want to listen in English while cooking, an English voice track may be more useful. Our Spanish-to-English video translation guide covers that workflow, including updating the voice after a text change.

Start with one complete instruction from your video. Create a Spanish-to-English project in SoulDub, compare the source and translated line, then take the English SRT through the caption checks above. That short section will give you a practical feel for the work before you tackle a whole lesson.
