SRT Translation: How to Translate an SRT Subtitle File

SRT translation converts a SubRip (.srt) subtitle file from one language to another while keeping its timestamps intact. The reliable way is to transcribe the source audio, translate the timed text, and export a fresh SRT. PlainScribe does this across 47 languages at up to 99% accuracy for $0.067/min ($4 per audio hour).

TL;DR

• What it is: translating the text inside an SRT file without touching the in/out timecodes.
• Best method: translate from the source audio so timing stays exact, then export a new SRT. PlainScribe handles this in one upload.
• 47 languages supported for translation, source language auto-detected.
• Cost: $0.067/min, or $4 per audio hour. A 30-minute video's SRT translated to one language costs about $2.01.
• Subscription-free and private: files auto-delete after 7 days; 30 free minutes, no card.

What an SRT File Looks Like

An SRT is plain text: a sequence number, a start-and-end timecode, and one or two lines of caption.

1
00:00:10,500 --> 00:00:13,000
This is the first subtitle.

2
00:00:15,000 --> 00:00:18,000
And this is the second subtitle.

Translating it means replacing the caption lines with the target-language text while leaving the numbers and timecodes exactly as they are. Do that by hand and a single shifted timecode desyncs the whole file.

How to Translate an SRT File the Right Way

Editing an SRT line by line is slow and error-prone. The faster, safer path is to translate from the source audio, which guarantees the timecodes match the speech.

1. Open PlainScribe and upload the video or audio the SRT belongs to (up to 200MB).
2. It transcribes the original audio at up to 99% accuracy, auto-detecting the language.
3. Choose your target language from the 47 supported. PlainScribe translates the timed transcript and keeps every timecode.
4. Export a new SRT (or VTT) in the target language. Repeat the language step for additional tracks.

This avoids the classic SRT pitfalls: broken timecode formatting, off-by-one block numbers, and accumulated sync drift.

SRT Translation Methods Compared

| Method | Timing risk | Speed | Cost | |---|---|---|---| | Manual edit in a text editor | High (easy to break timecodes) | Slow | Free | | Generic machine-translate the file | Medium (format errors common) | Fast | Varies | | Re-transcribe + translate from audio (PlainScribe) | Low (timestamps regenerated) | Fast | $0.067/min |

Verdict: for clean, in-sync results, regenerating the SRT from the source audio with PlainScribe beats hand-editing every time. See the pricing page.

FAQs

How do I translate an SRT file to another language? The cleanest method is to upload the matching video or audio to PlainScribe, transcribe it, select a target language, and export a translated SRT. The timecodes are regenerated correctly so nothing desyncs.

Can I translate an SRT without the original video? You can paste the text into a translator, but that risks broken timecodes and format errors. If you have the source media, translating from audio is more reliable. For the broader workflow, see subtitle translation.

Will translating change the subtitle timing? It should not. PlainScribe preserves timestamps when it translates, so each line lands on the same frames as the original. Manual editing is where timing usually breaks.

How many languages can I translate an SRT into? PlainScribe supports 47 languages for translation, with the source language auto-detected. You can export several language versions from one upload.

How much does SRT translation cost? $0.067 per minute of source audio, or $4 per audio hour. A 30-minute video costs about $2.01 per target language, with a $10 minimum that covers roughly 150 minutes.
