Split into Chunks
Split a video or audio file into equal-duration chunks for batch processing.
Overview
The Split into Chunks node divides a video or audio file into a series of fixed-duration segments. Each chunk is output as a separate audio file (and, when a video is split, as a separate video clip). Use it to break long recordings into manageable pieces before transcription, translation, or per-clip generation.
When to Use
- Split a long podcast or interview before feeding each segment to Transcribe
- Divide a long video into scene-length clips for parallel processing
- Break up an audio file into equal parts for dubbing or Voice Changer
Configuration
| Field | Type | Default | Description |
|---|---|---|---|
| Chunk Duration | number (seconds) | 10 | Length of each chunk in seconds (minimum 1) |
| Audio Format | select | mp3 |
Output container for audio chunks: MP3, WAV, or AAC |
| Output Chunk | select (post-run) | 0 | Which chunk index to pass to downstream nodes (0-based). Visible after a successful run. |
Inputs & Outputs
Inputs:
video-in— a video file to splitaudio-in— an audio file to split
At least one input is required. Connecting both will split the audio from the video and the video independently.
Outputs:
video-out— the selected video chunk (when a video input is connected)audio-out— the selected audio chunk
After execution, a chunk selector appears in the config panel so you can choose which chunk flows to downstream nodes.
Pricing
2 credits per execution.
Common Use Cases
- Batch transcription: split a 60-minute recording into 10-minute chunks, then fan-out to Transcribe nodes in parallel
- Long-form dubbing: split a video, dub each segment, then recombine with Combine Videos
- Per-scene video generation: break source footage into 5-second clips for independent transformation
Tips
- Use a List node driven by chunk count to iterate all chunks automatically.
- The chunk selector in the config panel only affects which chunk is passed when you wire
video-outoraudio-outto a downstream node; all chunks are still available in the result panel for download. - WAV output preserves lossless quality; use AAC for smaller files on mobile delivery pipelines.
