Working with Files: Subtitles, Chapters, and More

You can mark up chapters for quick navigation to key video segments, attach supplementary materials (such as images or PDF files), and upload subtitles. These features improve content accessibility and help viewers navigate video more easily.

Who this article is for

• Course creators — need to add subtitles, chapters, and supplementary materials to lessons
• Marketers — need to improve content accessibility and add interactive elements
• Instructors — need to structure learning materials using chapters and annotations
• Website owners — need to make video more accessible and easier to navigate

Annotations

Annotations are a tool that helps viewers quickly understand the video content and find key moments through brief explanations.

How to add annotations

1. Go to the video settings and open the “Interactions” tab.
2. Enable the “Annotations” feature and click “Add”.
3. Specify the exact time when the annotation should appear, add text, and if needed, insert a link.

The annotation will appear on the timeline below the video. You can move it along the timeline and add new annotations to other points in the video.

Supplementary videos

This feature lets you place a link to another video from Kinescope directly in the player. For example, if you briefly mention a topic in a video, you can add a link to a video with a more detailed explanation.

How to add a supplementary video

1. Go to the video settings and select the “Interactions” tab.
2. Enable the “Supplementary videos” feature and click “Add video”.
3. Select the desired video from your Kinescope library, add a title, and specify the exact appearance time on the timeline.

Save changes to make the video accessible in the player. You can move the links on the timeline and add other videos to empty sections.

Attachments

The “Attachments” feature lets viewers access supplementary materials while watching a video. This is convenient if you want to provide access to presentations, instructions, or other downloadable files.

How to add attachments

1. Open the video settings and go to the “Interactions” tab.
2. Enable the “Attachments” feature.
3. Upload files by dragging them to the designated area or via the file manager.
4. Arrange the files as needed.

Viewers will be able to open and download attachments by clicking the paperclip icon in the player.

Subtitles: generating and managing

How to upload subtitles

1. Go to the “Subtitles” tab in the video settings.
2. Upload a file in SRT or WebVTT format by dragging it to the upload area or selecting it manually.
3. Specify the subtitle language and, if needed, add a description.
4. Enable subtitles by toggling the “Show in player” switch.
5. Click “Save”.

Auto-subtitles

Use auto-generation to speed up working with subtitles.

1. Open video settings → Subtitles tab.

2. Click AI Auto-generate and select the subtitle language. While processing, the subtitles block shows a loading indicator.

   

3. Review the result. You can add, merge, or delete text manually. In the additional options menu (⋮), you can also replace, download, and adjust timings.

4. Select the generated subtitles, turn on Show in player (if not already on), and click Save.

Chapters

Adding chapters lets viewers easily find the moments they need and share specific segments of long videos.

How to add chapters

1. Go to the “Chapters” tab.
2. Use one of the following methods:
3. Manually enter the chapter start time and its name.
4. Or add chapters from the player:
5. Click “Add chapter”, enter a name.
6. Go to the desired moment in the video, pause playback, and click “Add chapter” again.
7. After adding all chapters, toggle the “Enable table of contents” switch.
8. Click “Save”.

Auto-generate chapters

Placing chapters in a long video manually takes time. Auto-generation helps: it analyzes the video and suggests timecodes with titles.

1. Open video settings → Chapters tab.

2. Click the gear icon next to AI Auto-generate if you want to change settings:

   — Maximum number of chapters — up to 99 (default 30). — Generation language — language of chapter titles.

3. Click AI Auto-generate. While processing, a loading indicator appears in the chapters block.

4. Review the result. You can edit titles and timecodes manually, and add missing chapters with Add chapter in the preview.

5. Enable Enable table of contents (if not already on) and click Save.

You can combine auto-generation and manual markup: generate a draft, then refine it.

Files

This section shows a list of available video resolutions that are automatically created when files are uploaded to Kinescope. During playback, the video resolution adapts to the player placement on the site, device, and viewer’s internet speed.

You can download the version of the video or subtitles you need:

1. Go to the “Files” tab.
2. Find the file you need in the table and hover over its row.
3. Click the “Download” button.

Audio tracks

Kinescope supports adding multiple tracks to a video, uploaded as a single file — for example, packaged using MKVToolNix.

1. Make sure your audio tracks are in .mp3 format. If not, use an audio file converter such as Convertio .
2. Download and install MKVToolNix. Version for Windows and macOS .
3. Open the program and add the audio files using the “Add source files” button.
4. Select the desired audio track in the lower-left menu and edit its properties. If this is a supplementary track, uncheck the “Default track” checkbox. Set the appropriate language in the language settings.
5. Click “Start muxing” and choose a save location. Return to Kinescope and upload the file. Additional audio tracks will appear in the video automatically.

Lead forms

Kinescope supports lead forms in video, but they cannot be configured independently yet. The development team will help you add lead forms to your video content — simply contact the support chat within the Kinescope interface.

After configuring file interactions, we recommend:

1. Media file settings — basic video settings
2. Customize the player — configure chapter and subtitle display in the player
3. Set up analytics — track how viewers use chapters and subtitles
4. Organize your media library — structure content using projects and folders
