How do I add audio and subtitles?

Each page in your template can have multiple audio tracks and subtitles. These are configured directly in the Studio editor and are automatically included when you render the template as a video.

Adding Audio#

Click the speaker icon in the timeline bar below the canvas to open the audio panel.

Upload#

Drag and drop or click to upload an audio file. Supported formats: .mp3, .wav, .m4a, .ogg, .aac (max 10 MB).

Once uploaded, the audio appears in the timeline and is attached to the current page.

Generate a Voiceover#

Click Voiceover, enter your script, choose a voice, then click Generate. Orshot adds the voiceover to the page with word timings that can be reused for captions.

Turn on Set per render to make the script a dynamic parameter. You can then send different spoken copy for each render without rebuilding the template.

Generate Ambient Audio#

Click Ambient, describe the sound you want, and choose its duration. Use ambient audio for music beds and sound design rather than spoken narration. Turn on Loop when it should fill a longer page.

Multiple Audio Tracks#

Each page supports multiple audio tracks — for example, background music and a voiceover. Click Add Audio Track in the audio panel to add another track. Each track has independent controls for volume, trim, offset, fade, loop, and mute.

The maximum number of audio tracks per page depends on your plan. Tracks are shown as collapsible sections in the audio panel and as separate bars in the timeline.

Audio Controls#

Timeline#

When audio is attached, a draggable bar appears in the expanded timeline. You can:

• Drag to reposition the audio (changes the offset)
• Resize edges to adjust trim points
• Hold and drag to slip-edit (shift the audio content within the trim window)

How Audio Renders#

All audio tracks on a page are automatically mixed into the video output alongside any audio from video elements on the same page.

• videoOptions.muted: true mutes everything, including all audio tracks
• When muted is not set or false, audio tracks are included automatically
• Volume, trim, offset, fade, and loop settings are all applied per track during rendering
• Use videoOptions.audioSource to override or add audio URLs at render time via the API

Adding Subtitles#

Click the closed captioning icon in the timeline bar to open the subtitle panel.

Upload SRT#

Click Upload SRT to attach a subtitle file. Supported formats: .srt, .vtt.

The file is parsed and the cue count is shown in the panel.

Auto-Generate from Audio#

If the page has audio attached, click Generate from audio to create subtitles from the first track. Generated voiceovers reuse their word timings; uploaded and other audio is transcribed.

Subtitle Controls#

Word-by-Word Mode#

Set Display to Word by word to reveal captions as they are spoken. Choose Highlight for karaoke-style captions, Re-center to keep the growing line centered, or reveal by letter for a type-on effect. Pair the Center position with a transparent background for the classic Reels and TikTok look.

Word timing is generated during rendering. If transcription mishears song lyrics, upload an SRT with the correct lyrics instead.

How Subtitles Render#

Page-level subtitles are used automatically when rendering videos. If you also pass a videoOptions.subtitleSource in the API request, it takes priority over the page-level subtitle.

Subtitle styles configured in the editor are applied during rendering. API-level videoOptions.subtitle* properties (like subtitleColor or subtitleFontSize) override the page-level styles when provided.

Audio Waveforms#

Add a Waveform element to visualize a page audio track. Choose the track in the inspector, then adjust the bar color, count, spacing, alignment, and minimum height. The Studio preview shows a static waveform; video renders animate it with the selected track.

Multi-Page Templates#

Each page has its own independent audio tracks and subtitle configuration. When rendering a multi-page video slideshow with videoOptions.combinePages: true, each page's audio tracks and subtitles are included in its segment of the final video.
