Using video localisation in global marketing helps you find new markets and massively expand your reach. Whether you want to go global or share Spanish content, here's your guide on how to translate videos to text and more effectively leverage the importance of video localization in multinational marketing.
Methods to Translate Videos from Spanish
To translate audio files to English, choose between subtitling and dubbing. Each method suits different audiences.
Subtitling
Subtitling is a quick and cost-effective way to translate. It keeps the original audio while adding text. A November 2021 study showed 76% of U.S. and 75% of U.K. users prefer subtitles over dubbing. AI can now make subtitles highly accurate by syncing them with speech, making video presentation translation easier, especially from Spanish.
Dubbing and AI Lip-Syncing
Dubbing replaces original audio with translated voices. Traditional dubbing is costly, needing actors and studios. AI lip-sync apps like HeyGen transform this task. It can translate and match voiceovers to speakers' lip movements. This makes a natural experience possible without costly human dubbing. This technology examines facial motions and tweaks translations for better lip-syncing, effectively aiding video localisation from Spanish.
Translating Spanish Videos with AI: A Step-by-Step Guide
AI-powered tools make it easy to translate audio files for video presentation. Whether you need subtitles or dubbing, AI ensures high accuracy. Here’s a guide to help you translate from audio files using AI.
Selecting The Right AI Tool for Translation
Choosing an AI video translation tool is the first step. Each tool serves different needs.
Considerations:
- Subtitling needs: Pick tools with automatic subtitle generation for easy captioning.
- Dubbing needs: Use AI translate audio tools that translate spoken content to natural voiceovers.
- All-in-one solutions: Some platforms offer both subtitling and dubbing in one package.
Tool Selection Tips:
- Accuracy: Some tools translate better. Check reviews and test first.
- Customization: Edit options help fine-tune video presentation.
- Languages Supported: Ensure your tool translates Spanish to English.
- Export Options: Look for formats like SRT (subtitles), MP4 (video), or WAV (voice).
Improving AI Translation Quality
AI translation is growing from $2.34 billion in 2024 to $2.94 billion in 2025, showing a 25.2% CAGR. This highlights trust in AI translate audio tools, given their accuracy and efficiency improvements. As AI progresses, it delivers better language processing and refined translations, boosting overall quality and usability.
Uploading and Preparing the Video
Once your AI tool is ready, upload and prep your video for translation.
Video Preparation Steps:
- Check File Types: MP4, MOV, AVI usually work.
- Clear Audio: AI has trouble with noise or accents. Good audio improves transcripts.
- Trim Excess Parts: Remove unnecessary parts for better processing.
- Upload the Video: Use file dragging or cloud integration to get started.
Managing the Translation Process
After uploading, AI takes over. While automation speeds things up, human checking ensures quality.
Translation Workflow:
- AI Makes a Spanish Transcript: It listens and makes text.
- Review Spanish Text: Check for mistakes before English translation.
- Translate Text to English: AI auto-converts text for subtitles or scripts.
- Edit English Translation: Check accuracy, expressions, and errors.
- Choose Output:
- Subtitles (SRT, VTT, or captions)
- Dubbed audio (AI or manual voiceover)
- Export Final Translated Video: Download and use as needed.
Preserving Cultural Context
Translating isn't just swapping words—it's about keeping meaning and cultural context. AI gives a direct translation, but human review ensures accuracy and cultural fit.
Cultural Awareness
Spanish and English reflect different cultures. The University of California's research shows language as a cultural product shaped by power and social difference, making cultural adaptation vital for quality translation. Spanish often uses more elaborate language than English. Direct translations can sound off. To make sure translations flow naturally, consider:
- Idioms: They may not have equivalent English meanings.
- References: Some terms need explaining for English speakers.
- Humor: Jokes often need adapting more than translating.
- Formality Differences: Spanish is often more formal.
AI and Culture Sensitivity
Top AI tools keep cultural nuances, but human checks ensure they stay appropriate. Follow ethical AI practices to maintain respect and context.
Boosting Translation Precision
These strategies can enhance your results:
- Human-in-the-loop editing: Some platforms allow expert edits.
- Domain-specific training: Look for tools supporting jargon customization.
- Machine learning improvements: AI engines improve after corrections.
- Multiple checks: Compare various AI platform results.
Natural Pronunciation and Intonation
AI-translated content can sound odd if not careful.
Best Pronunciation Practices
Natural translations use:
- Adjusted speech rate: Spanish usually has more syllables.
- Stress patterns: Emphasis varies across languages.
- Emotion match: Emotional tones must align.
- Regional accents: Match your target audience with AI voices. Research shows that having rhythmic synchronization involves complex, long-term memory effects, which can improve understanding.
Google's research shows that having synchronized rhythm improves understanding. Advanced AI lets you clone voices and maintain emotional tones, crucial when creating talking avatar videos. Accurate lip syncing boosts viewer enjoyment.
Editing and Reviewing Translated Work
AI gets better, but human review is still necessary.
Review Importance
Focus on these when proofreading:
- Grammar and syntax.
- Misunderstood tech terms.
- Awkward, unnatural phrasing.
- Consistent terminology.
- Correct speaker indication for multi-person videos.
Bad translations drive viewers away. Careful review is essential when dealing with video localisation.
Using SRT Files for Precision
With SRT files, you gain timing control:
- Export the SRT file.
- Use a text or subtitle editor.
- Sync timing with speech.
- Correct translation flaws.
- Re-upload the fixed SRT file.
For longer works, batch processing saves hours.
Handling Videos with Multiple Speakers
Conversations pose translation challenges.
Managing Multiple Voices
Keep clarity in multi-speaker videos:
- Different colors for different speakers.
- Choose voice profiles for each speaker when dubbing.
- Add speaker names in subtitles if needed.
- Keep voice casting consistent in series.
Certain AI tools can detect speakers and ensure correct attribution.
AI vs. Traditional Translation Methods
AI translation saves time and money when video localisation is needed.
Cost Differences
Traditional methods are expensive. Human subtitling costs $10-$30 per minute, and dubbing $75-$150 due to expert work and studios. AI solutions are cheaper while keeping quality. Subtitling costs $2-$15 per minute, and dubbing $15-$50 with AI voices. AI video presentation is affordable for creators and businesses.
Time Savings
AI's speed is a major benefit. Traditional translation takes one or two days for a 10-minute video. Longer projects take weeks. AI translation tools can do the same work in one or two hours. Though human review adds some time, the process is much faster.
Scalability and Cost Savings
For big projects, AI cuts costs significantly. Companies localizing many hours save 40 60% with AI translation. This allows expanding into new markets easily, leading to more efficient multilingual campaigns. AI isn't perfect but helps with affordability, speed, and quality. By using AI in translation processes, companies save money and time while keeping accurate, culturally relevant translations through human checks.
