How to split / merge chunks?

AutoCaptions automatically segments your text into** chunks**, but you can fully control and adjust them.

What is a “chunk”?

A chunk is a group of words displayed together in a single caption.

Example:

• “This is great” → 1 chunk
• “This / is / great” → 3 chunks

Controlling chunks helps you manage the rhythm and readability of your captions.

How to split a chunk

To split a caption into smaller parts:

1. Open AutoCaptions
2. Open the Caption Editor
3. Select the caption you want to edit
4. Click on Split chunks

AutoCut will automatically split the sentence into smaller segments (up to word-by-word)
This is the fastest way to create dynamic, punchy captions.

How to merge chunks

To combine multiple chunks:

1. Open the Caption Editor
2. Select the captions you want to merge
3. Click on Merge chunks

AutoCut will group them into a single caption.

When should you split or merge?

Split chucks when:

• You want more rhythm and impact
• You’re editing short-form content (TikTok, Reels, Shorts)
• You want to highlight each word

Merge chucks when: 

• The text feels too fast or hard to read
• You’re working on long-form content
• You want a more natural reading flow

Don’t forget to click "Save" after making changes in the Caption Editor. Otherwise, your edits won’t be applied.
