How to Add Subtitles in HitFilm

Important: FXhome was sunset in January 2025. New users can no longer create FXhome accounts, register for HitFilm, or upgrade plans. This guide is intended for editors who already have a working legacy installation of HitFilm.

HitFilm delivers extensive VFX and compositing capabilities, but its legacy workflow requires users to create subtitles manually using text layers rather than a dedicated caption track. It does not provide the native SRT import, automatic captioning, and subtitle-track management found in many caption-focused editing tools.

For video producers who need accessible and searchable content, this can create a significant workflow bottleneck. By pairing an existing HitFilm installation with automated subtitles, you can substantially reduce manual transcription and text placement while still completing your visual edit in HitFilm.

Understanding the Importance of Subtitles in Video Production

Before diving into the technical workarounds, let’s address why subtitles matter enough to justify the extra effort with HitFilm.

Accessibility is essential for many organizations. Educational institutions, government bodies, employers, and public-facing services may be subject to accessibility requirements depending on their jurisdiction and the context in which the video is used. Captions also make content available to viewers who are deaf or hard of hearing.

Audience engagement can improve when videos include subtitles or captions. Many viewers encounter social videos without sound initially, so on-screen text can help communicate the message before they enable audio.

SEO and discoverability can improve when a transcript is published as indexable text alongside a video. Caption files also help supported platforms understand and present the spoken content, although the SEO effect depends on the platform and implementation.

Global reach becomes possible when you translate subtitles into multiple languages. A single video can serve audiences across several markets without requiring a complete visual re-edit.

For filmmakers and video producers using an existing HitFilm installation, the subtitle limitation creates a gap between creative capability and content accessibility.

Manual Subtitling in HitFilm: A Step-by-Step Guide

Because HitFilm does not offer a dedicated caption-track workflow, you can create visible subtitles with text layers. The exact menu names and controls may differ between legacy HitFilm versions.

Creating Text Layers for Subtitles

Step 1: Set up your timeline

Import your video into the HitFilm timeline
Create a composite shot if your project or HitFilm version requires one for the desired text treatment
Make the audio waveform visible so you can use it as a timing reference

Step 2: Add text layers

Create a text layer using the text or title controls available in your HitFilm version
Enter the first subtitle line
Create or duplicate additional text layers for subsequent subtitle segments

Step 3: Position your text consistently

Place the text near the bottom center unless your content requires a different location
Leave enough space between the text and the frame edges
Use consistent positioning across subtitle segments

Synchronizing Subtitles with Audio

Timing subtitles manually requires close attention:

Watch and listen to identify where each spoken segment begins and ends
Position text layers on the timeline to match the dialogue
Trim each layer’s duration so the subtitle disappears at the appropriate point
Review transitions between consecutive subtitles to prevent distracting overlaps or gaps

The amount of work varies considerably. A dialogue-heavy video may require dozens of individual text elements, while a short video with limited speech may need only a few.

Styling and Positioning Your Subtitles

Create a consistent appearance across all subtitle layers:

Font choice: Use a readable sans-serif typeface
Text size: Make the text large enough to read on smaller screens
Background: Consider a solid or semi-transparent background for contrast
Color: White or light text with a dark outline or shadow works across many backgrounds
Margins: Keep important text away from the extreme edges of the frame

Create one styled text layer and duplicate it rather than rebuilding the formatting for every subtitle.

Using External Subtitle Files with HitFilm

HitFilm does not offer a conventional workflow for importing SRT or WebVTT files as editable caption tracks. An external subtitle file is therefore most useful for creating a platform caption track or for burning subtitles into the completed export.

Generating SRT or VTT Files with Automated Tools

Automated transcription tools convert speech into timestamped text.

The process works like this:

Upload your video or audio file to a transcription service
Let the service generate a transcript with timestamps
Review the text, speaker labels, timing, and line breaks
Export the reviewed transcript as an SRT or WebVTT file
Upload the file to your distribution platform or use it in a post-export burn-in workflow

Sonix provides word-level timestamps and speaker identification, which can reduce the amount of manual timing and labeling required before export.

Graphic and Image-Based Workarounds

Some legacy community workflows convert subtitle text into transparent graphics or image sequences before importing the result into HitFilm. These methods are not a native subtitle feature and may require extensive manual timing.

Compatibility can vary between HitFilm versions, and a basic image sequence does not necessarily preserve the variable cue durations stored in an SRT file. Test the complete sequence carefully before relying on this method for a long project.

Post-Export Burn-In with FFmpeg

A more predictable workflow is to separate video editing from subtitle rendering:

Complete your edit in HitFilm without subtitles
Export the finished video at your desired quality settings
Generate and review an SRT file using transcription software
Burn the subtitles into the exported video with FFmpeg

A basic command is:

ffmpeg -i video.mp4 -vf subtitles=subs.srt output.mp4

Your FFmpeg installation must include support for the subtitles filter. You may also need to escape or quote file paths that contain spaces or special characters.

This approach keeps your HitFilm project uncluttered and produces permanently visible subtitles. Its main disadvantage is that you cannot preview the final rendered captions inside HitFilm unless you import the processed video again.

Streamlining Your Workflow with Automated Caption Generators

Manual subtitle creation becomes difficult to scale when you produce multiple videos regularly.

The Benefits of AI-Powered Subtitling

Modern transcription technology can change the subtitle workflow in several ways:

Speed: Automated processing reduces the need to type every spoken word manually
Review workflow: You can correct a generated draft instead of starting from a blank document
Timestamps: Word-level timing provides a useful starting point for subtitle cues
Repeatability: A consistent transcription and export process is easier to apply across multiple projects

For video production teams, the value increases as the volume and duration of content grow. The exact time saved depends on audio quality, dialogue density, terminology, and the amount of review required.

Choosing the Right Automated Subtitle Tool

Evaluate caption generators against your specific needs:

Language support: Does the service support your source and target languages?
Export formats: Can it produce SRT, WebVTT, and any other formats required by your distribution platform?
Editing capabilities: Can you correct the transcript and timing before export?
Speaker identification: Can it distinguish between speakers?
Terminology support: Can you improve recognition of names or specialized terms?

A suitable tool should combine automated transcription with a practical review interface and dependable subtitle exports.

Exporting Your HitFilm Project with Subtitles

Understanding the difference between burned-in and selectable subtitles helps you choose the right delivery method.

Hardcoded vs. Selectable Subtitles

Hardcoded or burned-in subtitles:

Are permanently embedded in the video image
Cannot be disabled by the viewer
Display consistently on platforms that do not support uploaded caption tracks
Are often used when captions need to remain visible in every playback environment

Selectable caption files or tracks:

Are stored separately or embedded as a selectable media track
Can usually be turned on or off by the viewer
May support multiple languages
Can provide better accessibility controls on compatible platforms

Because HitFilm does not provide native caption-track management, text layers and FFmpeg burn-in are the main options for permanently embedded subtitles. For selectable delivery, keep the SRT or WebVTT file separate and upload it to a platform that supports caption tracks.

Platform-Specific Export Considerations

Different platforms handle subtitles differently:

YouTube: Supports uploaded subtitle and caption files, including SRT and WebVTT, as well as several other formats
Vimeo: Supports SRT and WebVTT caption or subtitle files and recommends WebVTT
Social platforms: Burned-in captions can provide consistent visibility, but supported caption-upload features vary by platform, account, and publishing workflow
Broadcast delivery: May require specific caption formats, encoding standards, positioning, and quality-control procedures

Plan your subtitle workflow according to where the video will be delivered. Some projects may require both a burned-in version and a clean version accompanied by caption files.

Advanced Subtitle Editing: Styling, Timing, and Translations

Fine-Tuning Subtitle Timing

Even AI-generated subtitles benefit from human review:

Check line breaks: Avoid breaking phrases in ways that make them difficult to read
Verify synchronization: Confirm each subtitle appears and disappears at the correct time
Adjust reading time: Give viewers enough time to read complex lines
Handle overlapping speech: Make speaker changes and simultaneous dialogue clear

Quality subtitle editors allow you to review the text and timing while playing the source media.

Translating Subtitles for Global Reach

A typical multilingual subtitle workflow is:

Generate and review the transcript in the source language
Translate it into the target languages
Review the translations for context, names, tone, and specialized terminology
Export a separate subtitle file for each language
Upload multiple caption tracks or produce language-specific burned-in versions

AI translation can accelerate the first draft, but human review remains important for nuanced, regulated, branded, or high-visibility content.

Troubleshooting Common Subtitling Issues in HitFilm

Sync Errors

When subtitles drift out of sync with audio:

Confirm the project frame rate and exported frame rate are correct
Check whether the video or audio was retimed after the subtitle file was created
Verify that the subtitle timestamps use the correct format
Confirm that the subtitle file was generated from the final edit rather than an earlier cut

Formatting Problems

When text renders incorrectly, check:

Whether the chosen font is available on the system performing the export
Whether the text size and layer resolution suit the export resolution
Whether outlines, shadows, or backgrounds render as expected
Whether special characters use a compatible text encoding

Display Issues

When subtitles are invisible or cut off:

Verify that text layers are above the video layers
Check that the text remains within the visible frame
Confirm that no crop, mask, or transform is hiding the layer
Review the final exported file rather than relying only on the editing preview

Frequently Asked Questions

Can HitFilm automatically generate subtitles?

Legacy HitFilm installations do not include an automatic transcription or subtitle-generation workflow comparable to a dedicated captioning platform. You will need to create visible text layers manually or use an external transcription tool to generate subtitle content. Remember that FXhome was sunset in January 2025, so new HitFilm registrations and plan upgrades are no longer available.

What is the best way to add subtitles to a long video in HitFilm?

For longer videos, a practical approach is to complete the edit in HitFilm, export the final video, generate and review an SRT file with automated transcription, and then either upload the file to a platform that supports captions or burn it into the video with FFmpeg. This avoids creating and managing a large number of individual text layers in HitFilm.

How can I ensure my subtitles are accurate and properly synced?

Generate subtitles from the final edit rather than an earlier version, then review the transcript while playing the video. Check names, technical terms, speaker changes, cue boundaries, line breaks, and reading time. Word-level timestamps provide a useful starting point, but they do not eliminate the need for human review.

What’s the difference between open captions and selectable caption files or tracks?

Open captions are permanently rendered into the video and are always visible. Selectable captions are delivered as a separate file or media track that a compatible player can turn on or off. SRT and WebVTT are two common sidecar formats, although some platforms support additional formats. HitFilm text layers create open captions; selectable captions should be uploaded separately to the destination platform.

Can I translate subtitles for international audiences?

Yes. First generate and review an accurate source-language transcript, then use translation tools to create drafts in the target languages. Review each translation for context and terminology before exporting a separate subtitle file for each language. You can then upload multiple caption tracks or create language-specific burned-in versions.
