Get your message across, no matter the language.
What is professional subtitling?
Subtitling is the process of converting spoken content in a video into text that is synchronized with the visuals and audio.
Subtitles can be created in the same language as the original content or translated into another language.
Good subtitles involve much more than transcribing or translating what you hear. The text must be adapted to the available screen time, follow suitable reading speeds, use appropriate line breaks and remain consistent with the visuals and context.
The goal is to let viewers follow the content naturally, without missing important information or being distracted from what is happening on screen.
Subtitling services
Same-language subtitling
Also known as intralingual subtitling, this involves creating subtitles in the same language as the original audio.
It is particularly useful for corporate videos, training, interviews, educational content, social media and material intended to be viewed without sound.
What is included?
- Transcription and preparation of the spoken content.
- Spelling, grammar and punctuation correction.
- Segmentation and distribution of text into subtitles.
- Synchronization with the audio and image.
- Review of reading speeds and line lengths.
- Quality assurance of the final file.
Video translation and subtitling
Interlingual subtitling makes audiovisual content accessible to viewers who speak another language.
I translate and adapt subtitles from English into Spanish and from Spanish into English, taking into account the original meaning, cultural references and the constraints of the audiovisual format.
What is included?
- Translation of audiovisual content.
- Linguistic and cultural adaptation.
- Text condensation where necessary.
- Appropriate segmentation of sentences and units of meaning.
- Synchronization with dialogue.
- Linguistic and technical review.
The goal is to convey the message faithfully, naturally and in a way that is easy to read, rather than translating word for word.

Business videos are an essential tool for sharing information, training teams and presenting products or services.
I provide subtitling for organizations that need to share content with employees, clients and business partners in different countries.
Types of content:

Videos published on Instagram, YouTube, TikTok, LinkedIn and other platforms can benefit from clear, easy-to-follow subtitles.
I provide subtitling for content creators, professionals, brands and agencies looking to improve the accessibility of their posts and reach a wider audience.
Content I can subtitle:
- Reels and short videos.
- YouTube videos.
- Interviews and video podcasts.

Subtitles can be delivered as separate files or burned into the video, depending on the project’s needs.

I work with audiovisual content that requires particular attention to narrative pacing, dialogue, cultural references and technical subtitling conventions.
Types of content:
- Documentaries.
- Series and audiovisual productions.
- Short films.

Subtitles can be prepared according to the technical specifications provided by the client or distribution platform.
Subtitle correction and quality assurance
Do you already have subtitles and need to make sure they are correct?
I provide linguistic and technical review of existing subtitle files in both English and Spanish.
The review can include:
- Spelling and grammar correction.
- Verification of translation accuracy.
- Terminology and consistency review.
- Synchronization checks.
- Character-per-line checks.
- Reading speed checks (characters per second, or CPS).
- Review of minimum and maximum subtitle durations.
- Detection of overlaps and segmentation issues.
- Verification of compliance with the client’s technical guidelines.
This service is particularly useful for production companies, localization agencies and businesses that need to check subtitle quality before publishing or distributing content.
Subtitle file adaptation and adjustment
I can also adapt existing subtitle files to new versions of a video or specific technical requirements.
For example, I can correct timings, adjust segmentation, adapt subtitle length or prepare files for different platforms.
Delivery formats
Subtitles can be delivered in different formats, depending on where they will be used and the project’s requirements.
SRT files: one of the most widely used subtitle formats, compatible with many platforms and media players.
VTT files: commonly used for subtitles in web players and digital content.
Burned-in subtitles: the text is embedded in the video image and remains visible at all times.
Other formats: specific delivery requirements can be assessed according to the platform or the client’s workflow.
If you are unsure which format you need, I can help you choose the most suitable option for your project.
Why choose professional subtitling?
Accurate timing
Subtitles need to appear and disappear at the right moment, following the pace of the dialogue and allowing viewers to read comfortably.
Linguistic and cultural adaptation
Idiomatic expressions, cultural references and differences between languages require translation decisions that preserve the meaning without producing subtitles that are too long or difficult to read.
Compliance with technical requirements
Each platform or client may specify limits for character counts, reading speeds, duration and format. Subtitles are prepared and reviewed according to the specifications applicable to each project.
Experience in audiovisual localization
Audiovisual translation requires an understanding of the relationship between text, audio, images and narrative context.
My experience in multimedia projects and quality assurance allows me to approach subtitling from both a linguistic and a technical perspective.

Frequently asked questions about subtitling
What is the difference between subtitling and transcription?
Transcription converts the spoken content of an audio or video recording into text.
Subtitling also involves dividing that text into readable units, assigning start and end times and adapting it to the audiovisual content.
A transcript is not necessarily ready to use as a subtitle file.
Can I add English subtitles to a Spanish-language video?
Yes. I provide translation and subtitling from Spanish into English and from English into Spanish.
Subtitles are adapted to the target language so they read naturally and are easy to follow.
Can I add Spanish subtitles to a video that is already in Spanish?
Yes. This is called intralingual subtitling and is particularly useful for corporate videos, training, interviews, social media and content that may be viewed without sound.
Do subtitles need to reproduce everything that is said exactly?
Not necessarily.
Professional subtitling may require some expressions to be condensed to fit the available reading time, without losing essential information or changing the meaning.
The degree of condensation depends on the content and applicable guidelines.
How many characters can a subtitle contain?
There is no universal limit for every project.
The maximum number of characters per line depends on the platform, type of content and client specifications.
Other factors, such as reading speed, duration and linguistic segmentation, are also considered.
What is an SRT file?
An SRT file is a subtitle format containing text and timestamps that specify when each subtitle should appear and disappear.
It is compatible with many platforms, media players and video editing programs.
What is the difference between burned-in subtitles and SRT files?
Burned-in subtitles are part of the video image and cannot be turned off.
SRT files are uploaded separately, allowing the platform or player to display subtitles as an independent track where this feature is supported.
Can I upload the subtitles to YouTube?
Yes. YouTube allows compatible subtitle files, such as SRT, to be added to videos.
I can prepare the files for you to upload to your channel.
Are YouTube’s automatic captions or AI tools sufficient?
Automatic tools can provide a useful starting point, but they can also introduce errors in transcription, punctuation, speaker identification, segmentation and synchronization.
These issues tend to be more common with background noise, accents, specialist terminology or multiple speakers.
Professional review helps identify and correct errors that may affect understanding and a brand’s image.
Can I request only a review of AI-generated subtitles?
Yes. If you already have automatically generated subtitles, I can review both their language and technical aspects.
The scope of the review depends on the quality of the existing material and delivery requirements.
Can I send several videos for subtitling?
Yes. I can work on individual videos, video series, training materials, and long-term projects.
For larger projects, we can establish shared terminology and technical guidelines to maintain consistency across deliveries.
How much does it cost to subtitle a video?
Pricing is generally per minute of video. Whether the project requires transcription, translation, synchronization or review is also taken into account. You can send me your material for a personalized quote.
How long does subtitling take?
Delivery time depends on the length of the content, audio quality and technical requirements. You’ll receive an estimated delivery time when the project is assessed. You can also get in touch if you have an urgent project.
Do I need to send the original video file?
A good-quality version of the video is recommended, as it makes it easier to understand the audio and synchronize the subtitles.
Can I request a specific visual style for the subtitles?
Yes. For subtitles burned into the video, we can discuss requirements for the font, size, placement and visual style.
For SRT files, the final appearance depends mainly on the player or platform where they are used.
