How to Add Captions in LumaFusion (iPad Editing)

LumaFusion is a feature-rich video editing app for iPad, but LumaTouch’s current documentation does not describe built-in automatic caption generation or direct SRT/VTT subtitle import. Instead, you can create open captions with LumaFusion’s Titler and time each title clip on the timeline.

That does not mean you have to type every spoken word from scratch. By combining LumaFusion’s title tools with an automated transcription service such as Sonix, you can create a transcript first, review it, and then transfer concise caption segments into your project.

This guide covers the complete workflow, from preparing and transcribing your audio to styling, timing, and exporting a captioned video.

Key Takeaways

LumaTouch’s current documentation does not list built-in automatic caption generation or direct SRT/VTT subtitle import
Captions created with LumaFusion’s Titler are rendered into the exported video as open, or burned-in, captions
A practical workflow is to create one caption design, save it as a title preset, and split or duplicate title clips as you work
Using a reviewed transcript avoids typing the dialogue from scratch, although timing and formatting still require manual work
Sonix can provide speaker labels, word-level timestamps, and subtitle-file exports to help organize the captioning process
Burned-in captions maintain their appearance across platforms but cannot be turned off by viewers
Finalizing the project’s frame rate, aspect ratio, and main edit before captioning reduces the chance of later timing changes

Why Captions Are Essential for Your iPad Video Edits

Captions make video content accessible to people who are deaf or hard of hearing. They also help viewers follow speech in noisy environments, in quiet spaces where they cannot play audio, or when the speaker’s language is not their first language.

Accessibility obligations vary according to the organization, content, and jurisdiction. In the United States, Section 508 applies to federal agencies and covered federal information and communications technology. WCAG 2.1 Success Criterion 1.2.2, a Level A requirement, calls for captions for prerecorded audio in synchronized media. Effective captions should represent the dialogue and important sounds needed to understand the content. (W3C)

Captions can also support the practical goals of video creators:

Sound-off viewing: Viewers can understand the video without playing its audio
Broader accessibility: Dialogue and relevant sound information are available visually
Consistent presentation: Burned-in captions retain their chosen font, position, and colors
Content reuse: A transcript can also support articles, show notes, summaries, and other text-based content
International distribution: Translated transcripts can be used to produce separate language versions

For LumaFusion users, planning for captions before the final export prevents avoidable rework.

Setting Up Your LumaFusion Project for Captioning Success

Complete the main video edit before investing significant time in caption timing. Late changes to the sequence can move dialogue, shorten scenes, or require captions to be retimed.

Project Settings Checklist

Aspect ratio: Match the intended destination, such as 16:9 for standard landscape video or 9:16 for vertical video
Frame rate: Select the appropriate frame rate when creating the project and avoid changing the project format late in the workflow
Caption placement: Leave enough space for text without covering faces, labels, or other essential visual elements
Audio preparation: Use the clearest available dialogue track and reduce avoidable background noise before transcription
Edit status: Lock the main sequence as closely as possible before timing captions

LumaTouch’s current iOS feature page lists 12 video, audio, or graphic tracks and 12 additional audio tracks. A graphic track above the main footage can be used for title-based captions. (Luma Touch)

Storage Considerations

High-resolution source files, rendered previews, cached media, and exported versions can use substantial space. Check the available storage on your iPad before importing a long or high-resolution project.

LumaFusion also provides project archiving and media-management options. Remove only files that you are certain are no longer needed, and retain a backup of important source media and project archives.

Transcribing Your Audio: The First Step to Accurate Captions

Without an existing script or transcript, manual captioning requires you to listen, type, divide the text, and time each segment. That process can take considerably longer than the running time of the video.

Automated transcription creates a draft that you can review before transferring the text into LumaFusion.

Your Transcription Options

Manual typing: Listen to the video and type the dialogue yourself. This can be practical for a short video, a simple voice-over, or a project with very little speech.

An existing script: When the recorded dialogue closely follows a script, use it as a starting point. Check it against the final recording because speakers often change, omit, or add words.

YouTube automatic captions: YouTube can generate a caption draft after upload. The result should be reviewed for names, specialist vocabulary, punctuation, speaker changes, and misheard words.

Automated transcription software: A service such as Sonix can create a time-aligned transcript with speaker labels and word-level timestamps. Automated results still need human review, particularly when the recording contains background noise, accents, overlapping speech, proper names, or technical terms.

The Side-by-Side Workflow

Where supported by your iPad and current multitasking configuration, place LumaFusion beside the reviewed transcript in Safari, Notes, or another compatible app. You can then copy short sections into title clips without repeatedly closing and reopening the editor.

Another option is to keep the transcript open on a second device while editing in LumaFusion.

Generating Subtitles: From Transcript to Timed Text Files

A transcript contains the spoken text. A subtitle file adds start and end times so that a video player can display each segment at the appropriate moment.

Professional automated subtitles tools can divide a transcript into timed segments and export formats such as SRT or VTT.

Understanding Subtitle File Formats

SRT: A widely supported text format containing numbered subtitle segments and start/end timestamps
VTT: A web-oriented timed-text format that supports additional metadata and styling capabilities
TXT: Plain transcript text without standardized subtitle timing

LumaTouch’s current public feature documentation does not describe direct SRT or VTT subtitle import. For a LumaFusion-only workflow, use the timed subtitle file as a reference while creating and positioning title clips. Alternatively, export the finished video and attach the SRT or VTT file through a destination platform that supports closed captions.

Timing Best Practices

Caption requirements vary by platform, language, audience, and organization, but several principles apply broadly:

Keep each caption concise and easy to scan
Use no more than two lines when possible
Synchronize each caption closely with the corresponding speech
Give viewers enough time to read the text comfortably
Avoid covering essential visual information
Include meaningful non-speech audio when it is necessary to understand the scene
Identify a speaker when the speaker is not visually obvious and the identity matters

Do not insert arbitrary gaps when speech is continuous. Captions should follow the content rather than a fixed timing formula.

Importing Your Captions into LumaFusion

Because LumaTouch’s documented workflow is based on titles rather than imported subtitle tracks, “importing” captions into LumaFusion is effectively a process of transferring reviewed text into timed title clips.

Step-by-Step Caption Creation

Step 1: Create a master caption design

Add an Overlay Title to a track above the video and open it in the Title Editor. LumaFusion supports multilayer titles, text, shapes, images, fonts, colors, borders, and shadows. (Luma Touch)

Set the main visual properties:

Choose a readable sans-serif font
Select a size that remains legible on the smallest screen you expect viewers to use
Use sufficient contrast between the text and video
Add a solid or partially transparent background shape when the underlying footage changes frequently
Position the caption away from faces, names, controls, and other important information
Test the design with both bright and dark footage

Save the finished design as a Title Preset or Style Preset so you can reuse it. LumaTouch documents saved style presets for individual text or shape layers and title presets for complete multilayer title designs. (Luma Touch)

Step 2: Create the first timed caption

Trim the title clip so that it begins and ends with the corresponding phrase. Open the title and replace the placeholder text with the reviewed caption.

Step 3: Split or duplicate the caption clip

One efficient approach is to extend a styled title over a longer section and split it at each caption change. You can also duplicate a short title clip or apply your saved Title Preset to additional clips.

Splitting or duplicating a styled title helps maintain its position and general appearance, but it is not the only valid method.

Step 4: Replace the text in each segment

Work through the timeline in order:

Play the dialogue and locate the next caption change
Place the playhead at the intended cut point
Split or trim the title clip
Open the relevant segment
Replace its text with the next reviewed caption
Play the transition and adjust the timing as needed

Zoom into the timeline for precise edits, but judge the result through normal-speed playback as well as frame-by-frame inspection.

Step 5: Review the complete sequence

Watch the entire captioned video and check for:

Missing or duplicated words
Captions that appear too early or disappear too late
Text that is difficult to read against the footage
Captions covering essential visual content
Inconsistent capitalization, punctuation, or speaker labels
Lines that are too long for comfortable reading

Styling Your Captions for Visual Impact in LumaFusion

LumaFusion’s Title Editor supports custom fonts, colors, borders, shadows, shapes, imported graphics, and reusable presets. (Luma Touch)

Design Recommendations

Font: Use a clear typeface with distinguishable letterforms
Size: Test the exported result on a phone rather than relying only on the larger iPad preview
Contrast: Use a text color and background treatment that remain readable over changing footage
Position: Place captions where they do not hide faces, demonstrations, on-screen names, or controls
Line length: Break long sentences into short, natural phrases
Animation: Use motion sparingly because animated text can reduce readability
Consistency: Keep the same core styling throughout the video unless a deliberate change communicates meaning

Presets and Clip Attributes

For repeatable caption styling, save your design as a Title Preset or save individual layer styling as a Style Preset. These tools are designed to reuse the contents and appearance of titles.

LumaFusion also has an Attributes Clipboard for supported clip-level settings, including frame and fit, blending, audio, color, and effects. It can help when clips need the same positioning or other compatible properties, but title presets are the more direct option for preserving title-layer design. (Luma Touch)

Advanced Captioning Techniques: Multi-Language and Beyond

For creators serving multilingual audiences, a reviewed source-language transcript can be translated and used to create separate captioned versions.

Creating Multi-Language Versions

A practical workflow is:

Generate and review the source-language transcript
Translate the approved transcript
Review the translation with a fluent speaker when accuracy is important
Duplicate the LumaFusion project or timeline for the new language
Replace the original captions with the translated text
Adjust line breaks and timing because translated phrases may be longer or shorter
Export each language version separately

Sonix currently advertises automated transcription in 54+ languages and provides word-level timestamps and speaker identification. (Sonix)

Burned-In vs. Optional Captions

Burned-in or open captions: These are permanently rendered into the picture. They maintain the chosen styling on any platform, but viewers cannot turn them off.

Optional or closed captions: These remain separate from the video and can usually be enabled or disabled by the viewer. They require a compatible player and an accepted timed-text format such as SRT or VTT.

A LumaFusion title-based caption track becomes part of the rendered video. Keep the separate SRT or VTT file as well when a platform supports optional captions.

Optimizing Your LumaFusion Export with Captions

Encoding and platform recompression can affect fine text, so inspect a short test export before rendering a long project.

Recommended Export Approach

Resolution: Match the intended destination and the project’s source quality
Frame rate: Keep the export consistent with the project
Quality: Select a quality setting appropriate for the delivery platform and available storage
Format: Choose a format accepted by the destination platform
Review: Watch the exported file on a phone and check small text, thin strokes, and background transparency

LumaTouch’s current iOS page confirms that LumaFusion allows users to control movie resolution, quality, and format. (Luma Touch)

Export destinations may vary according to the installed LumaFusion version, operating system, and available apps. Exporting to Files or Photos before uploading through the destination platform is generally the safest option when you also need to attach a separate caption file.

Platform-Specific Considerations

YouTube: Supports creator-supplied subtitle files and can also generate automatic captions. Review either version before publication.
Instagram: Offers captioning features for supported content. Burned-in captions remain useful when exact visual styling is important.
TikTok: Provides automatically generated captions for uploaded videos. Creators should review them and may still choose burned-in captions for consistent branding. (TikTok Support)
Other platforms: Check the platform’s current documentation before publishing because file support and upload procedures can change.

Why Sonix Makes LumaFusion Captioning Faster

LumaFusion’s title-based caption workflow still requires manual segmentation and timing. Sonix can handle the transcription stage so that you begin with editable text rather than a blank title.

How Sonix Complements LumaFusion

The workflow is straightforward:

Upload your video or audio file to Sonix
Wait for Sonix to generate a transcript
Review the text in Sonix’s synchronized browser editor
Correct names, technical terms, punctuation, and speaker labels
Export the transcript as TXT, DOCX, SRT, VTT, or another suitable format
Use the reviewed text and timestamps as a reference when creating captions in LumaFusion

Sonix says its transcription system processes a typical one-hour recording in approximately five to six minutes, although actual processing time and transcript quality vary according to the file, audio conditions, language, and system load. (Sonix)

This workflow avoids typing the full transcript from scratch. The final caption timing, line breaks, visual styling, and quality review still need to be completed in LumaFusion.

Key Sonix Features for Video Creators

Multi-language transcription: Transcribe audio and video in 54+ languages
Speaker identification: Organize interviews and conversations by speaker
Word-level timestamps: Locate phrases and approximate caption changes more quickly
Team collaboration: Share transcript work with editors and reviewers
Synchronized editing: Review the recording while editing the transcript
Flexible exports: Export Microsoft Word, TXT, PDF, SRT, VTT, and other supported formats

Sonix’s official help documentation confirms that subtitle exports include SRT and VTT and that transcript exports can include speaker names and timestamps. (Sonix Help)

Final Verdict: Streamlining Your LumaFusion Caption Workflow

LumaFusion provides flexible title-design and timeline tools, but its documented in-app caption workflow remains title-based. For longer videos, the transcription stage can become a significant part of the work.

Choose a fully manual LumaFusion workflow when:

The video is very short
You have a final script that closely matches the recording
The content contains little dialogue
You need complete control and do not mind typing the text yourself

Choose Sonix paired with LumaFusion when:

You produce dialogue-heavy videos regularly
Your content includes interviews, presentations, or podcasts
You need speaker labels or word-level timestamps
You want a reviewed transcript before creating title clips
You need SRT or VTT files for platforms that support closed captions
Multiple people need to review or edit the transcript
You plan to translate or repurpose the spoken content

Sonix can make the transcription portion of the process more efficient by generating editable, time-aligned text. LumaFusion can then handle the visual design, timing, and final open-caption export.

The result is not a direct software integration or one-click caption import. It is a complementary workflow: Sonix prepares and organizes the language, while LumaFusion controls how that language appears in the finished video.

Frequently Asked Questions

Can LumaFusion automatically generate captions?

LumaTouch’s current public documentation does not describe a built-in automatic caption generator. The documented in-app option is to create text with the Titler and place title clips on the timeline. A reviewed transcript from an external service can reduce typing, but the captions still need to be divided, timed, and checked in LumaFusion.

What’s the best way to get accurate transcripts for my LumaFusion videos?

Use automated transcription to generate a draft, then review it against the recording before creating captions. Sonix provides synchronized playback, speaker labels, and word-level timestamps, but names, jargon, accents, overlapping speech, and low-quality audio can still require correction. The reviewed transcript can then be kept beside LumaFusion as you build the title clips.

How do I ensure my captions are synced with my video in LumaFusion?

Complete the main edit first, then trim or split each title clip so that it follows the corresponding speech. Zoom into the timeline for precise changes, play each transition at normal speed, and review the entire exported video before publishing. Splitting or duplicating one styled title can maintain consistency, but saved title presets are also useful.

Can I export my LumaFusion video with burned-in captions?

Yes. Text placed in LumaFusion as title clips is rendered into the finished picture when the video is exported. These open captions display anywhere the video plays, but viewers cannot switch them off. Keep a separate SRT or VTT file when the publishing platform also supports optional closed captions.

Are there any tools to help create captions before using LumaFusion?

Yes. An existing script, YouTube’s automatic captions, or an automated transcription service can provide the source text. Review any automatically generated transcript before publication. Sonix can also export SRT and VTT files, which can be used as timing references in LumaFusion or uploaded separately to platforms that accept closed-caption files.
