# Split into Chunks

> Cut a long video or audio file into equal-length chunks, as audio files and video clips, so you can transcribe, dub or transform each piece separately.

Source: https://nodaro.ai/docs/nodes/video/split-into-chunks

The **Split into Chunks** node cuts a video or an audio file into pieces of equal length. Every chunk comes out as a separate audio file and, when you split a video, as a separate video clip. Use it to break a long recording into manageable pieces before transcription, translation or per-clip generation.

- Found in: Video › Cut & Assemble
- Output: video
- API type: `split-media`

## When to use it
- Split a long podcast or interview into segments before you transcribe them with [Transcribe](https://nodaro.ai/docs/nodes/audio/transcribe).
- Divide a long video into scene-length clips that you process separately.
- Break a recording into equal parts for [Dubbing](https://nodaro.ai/docs/nodes/audio/dubbing) or [Voice Changer](https://nodaro.ai/docs/nodes/audio/voice-changer), then join the results again with [Combine Videos](https://nodaro.ai/docs/nodes/video/combine-videos).
- Cut source footage into 5-second clips that you transform one by one.

## Quick start
### Add the node

Press Tab on the canvas and choose **Video › Cut & Assemble › Split into Chunks**.

### Connect the media

Wire a video into the **Video** input, or an audio file into the **Audio** input.

### Set the chunk length

Open the settings panel. Set **Chunk Duration (seconds)** and choose an **Audio Format**.

### Run it and choose a chunk

Click **Run** on the node. The chunks appear in the settings panel. Choose the chunk to pass on under **Output Chunk**.

Workflow: A 30-minute talk is cut into 5-minute chunks, and the selected audio chunk goes to Transcribe.

- Upload Video → Split into Chunks (video)
- Split into Chunks → Transcribe (audio)

## Inputs
| Input | Accepts | What it does |
| --- | --- | --- |
| **Video** | Video nodes, such as Upload Video and Generate Video | A video to split. |
| **Audio** | Audio nodes, such as Upload Audio and Reference Audio | An audio file to split. |

Connect at least one input. With both inputs connected, the node splits the audio file and the video independently.

## Outputs
| Output | What it carries |
| --- | --- |
| **Video** | The selected video chunk, when a video is connected. |
| **Audio** | The selected audio chunk. |

## Settings
| Setting | What it does |
| --- | --- |
| **Chunk Duration (seconds)** | The length of each chunk. The default is 10 seconds, and the minimum is 1 second. |
| **Audio Format** | The file type of the audio chunks: **MP3** (the default), **WAV** or **AAC**. |
| **Output Chunk** | Appears after a successful run. Choose **Chunk 1**, **Chunk 2** and so on: the selected chunk is the one that flows to connected nodes. |

## Download the chunks

After a run, the settings panel lists the **Audio Chunks** and, for a video, the **Video Chunks**. Every chunk stays in these lists, whatever you choose under **Output Chunk**. Use **Select All** or **Deselect All** to choose chunks, then click **Download** to save them.

## Credits
Split into Chunks costs 20 credits per run, whatever the number of chunks.

## Tips
- **Choose the format for the job.** **WAV** keeps lossless quality. **AAC** gives smaller files, for example for mobile delivery.
- **Pick the chunk that moves on.** **Output Chunk** only changes which chunk flows to the next node. All chunks stay available for download.
- **Cut one part only.** To take a single section of a video instead of equal pieces, use [Trim Video](https://nodaro.ai/docs/nodes/video/trim-video).

## Frequently asked questions

### How long is each chunk?

As long as you set in Chunk Duration (seconds). The default is 10 seconds, and the minimum is 1 second.

### Which chunk goes to the next node?

The chunk you choose under Output Chunk. The setting appears in the settings panel after a successful run.

### Can I download all the chunks?

Yes. After a run, the settings panel lists every audio chunk and video chunk. Select the chunks you want and click Download.

### Which audio format should I choose?

MP3 is the default and suits most uses. Choose WAV for lossless quality, or AAC for smaller files, for example for mobile delivery.
