How AI Auto Translate Subtitle works

One of the greatest features of modern large-language models (LLMs) is their ability to provide accurate and naturally-sounding translations preserving tone and style of original text.

Surprisingly, the AI is capable of providing high quality translations even for less common languages with smaller amounts of training data, like Mongol, Kyrgyz and even some of the dead languages.

AI has changed the game for subtitle translation. It's faster, more efficient, and getting better at accuracy.

What AI Translation Does

AI automates subtitle translation from one language to another. It's perfect for:

Keep in mind: AI's accuracy can vary based on the language pair and content complexity.

Of course, for more common languages with plenty of training data, especially American English and European languages, the translations are nearly perfect. You can even transcribe the video automatically if it is in English, and then run translator with automated captions and get a decent result. AI can caption content from native English speakers, especially in America, with nearly a hundred percent accuracy.

But AI still stumbles with heavy accents, tech jargon, and cultural jokes. That's where human touch comes in handy.

AI Translation Quality

Quality is key in subtitle translation. Let's look at AI translation accuracy and how it compares to human translation.

How Good is AI for Auto Translation?

AI translation has improved, but it's not flawless. Some language pairs work better than others. English to Spanish? Pretty good. English to Vietnamese or Khmer? Not so much.

AI is great at staying consistent across long texts. Humans can struggle with that on big projects.

One of the upsides of using automated subtitle translator like TranslateSRT.online is that you'll automatically get better translations over time when new LLM models are released.

AI vs Human Translation

Let's compare the two:

Aspect AI Translation Human Translation
Speed Lightning fast Slower, depends on project size
Cost Cheaper Pricier, especially for niche content
Accuracy 80%+ (GPT-4o) Up to 99% with pros
Context Keeps context Gets nuances and subtleties
Creativity Avoids Shines in creative adaptation

Checking Translation Quality

To make sure your subtitles hit the mark:

  1. Use QA tools: Start with spellcheckers and grammar tools.
  2. Get human eyes on it: Have a native speaker or pro translator take a look.
  3. Try back translation: Translate the subtitles back to the original language to spot issues.
  4. Test with your audience: Show the translated video to some target viewers for feedback.

Translation Speed

AI translation is FAST. With TranslateSRT.online you can translate thousands of kilobytes of subtitles in minutes. Many our users use the service to translate entire seasons of TV shows in couple of minutes.

Another common use case is for YouTube or TikTok content creators: after releasing a new video they are able to add 30-40 new languages in less than 10 minutes, expanding their reach to millions of new viewers.

Markup, Formatting, Timings

All subtitle formats like .SRT, .VTT, .ASS have strict requirements for the content formatting: the timestamps must follow specific format, there must be line breaks between captions, there must be no trailing whitespaces and so on.

AI tools can handle various text elements, but they have limits, especially if you use 'vanilla' ChatGPT or Claude API. They tend to ignore, break or alter existing formatting, which is absolutely unacceptable when working with subtitle file formats like .SRT or .ASS.

TranslateSRT.online is designed to ensure the formatting is kept exactly as it is in original file, and bold, italic text and emojis are where they are supposed to be.

Make sure your SRT/VTT/ASS files are properly formatted before uploading.

Similar to markup and text styling, 'pure' GPT models and other LLMs sometimes alter the markup that breaks the file structure. Small changes like replacing commas with periods in timestamps renders the .SRT files useless, but our service is designed to make that issue non-existent. We only translate subtitle contents and then compile them back keeping original structure, which guarantees that original timings and formatting of the file is kept intact.

Pricing Guide

You can translate up to 10 KB for free every day. The counter is reset every 24 hours, so you can use the service for free basically forever. For bigger translations, we have volume-based pricing that is 256 KB per $1.

Tips for Better Results

Want to make your AI subtitle translations shine? Here's how:

File Preparation

Get your files ready for smooth sailing:

  • Use .SRT, .VTT or .ASS formats for TranslateSRT
  • Check subtitle numbering and formatting. There should be no duplicated line numbers, no double line breaks, no non-standard Unicode characters, no trailing white spaces
  • Use the right timing format (for example in .SRT: 00:00:00,000 --> 00:00:00,000)
  • In .SRT, there must be blank lines between subtitles
  • Use UTF-8 encoding

Checking Results

Don't just trust the machine. Always double-check:

Read through the whole thing. Does it make sense? Does it flow well? Check the timing against the video. Look for obvious mistakes in names or numbers. Run it through spellcheck and grammar tools. If you can, get a native speaker to take a look.

Pro tip: Try translating it back to the original language. It's a great way to spot issues.
