# Exporting And Bouncing

> Render scenes and channel output to files you can share, archive, or move into another workflow.

# Export as audio + video

Bouncing prints your arrangement to files on disk.

## What the bounce flow can persist

Current bounce settings include:

* export master
* export channels
* export WAV (with configurable bit depth)
* generate video
* open folder after export

## Output location

Bounces are written to:

* macOS: `~/Documents/Meiji Sampler/Bounces/`
* Windows: `Documents\Meiji Sampler\Bounces\`
* Linux: `$XDG_DOCUMENTS_DIR/Meiji Sampler/Bounces/` if set, otherwise `~/Meiji Sampler/Bounces/`

The app generates date-and-time-based filenames and can create channel-specific files when exporting stems/channels separately.

## WAV bit depth

The bounce modal lets you choose the bit depth for exported WAV files. When WAV Audio is enabled, use `Left`/`Right` on the WAV Audio row to cycle through:

| Option           | Format         | Use case                                                                                                     |
| ---------------- | -------------- | ------------------------------------------------------------------------------------------------------------ |
| 16-bit           | Signed integer | Smallest files. Standard for final distribution and casual listening.                                        |
| 24-bit (default) | Signed integer | Good balance of fidelity and file size. Preferred for handoff to a DAW or archiving.                         |
| 32-bit float     | IEEE 754       | Lossless from the engine's internal processing. Use when you need maximum dynamic range for post-production. |

Meiji Sampler processes audio internally at 32-bit float precision. Choosing 24-bit or 32-bit float preserves more of that precision in the exported file. The setting persists across sessions.

## Good default export

For most users:

* export master: on
* export channels: off
* export WAV: on (24-bit)
* generate video: off

## Exporting stems (channel export)

When **Export Channels** is enabled, each channel is rendered as a separate WAV file alongside (or instead of) the master. Files are named by channel number and any assigned channel name.

The master WAV captures the performed master output, including live PerformFX gestures. Channel exports stay pre-master-FX so stems remain clean for later mixing.

Use channel export when you want:

* a handoff into a DAW for further production
* separate stems for later mixing or mastering
* to archive the session in a modular format you can remix later

Channel export can be combined with master export (both get written) or used alone. If you only need stems and don't want a mixed master, turn off **Export Master** and enable **Export Channels**.

## MP4 visualizer

When **MP4 Visualizer** is enabled, Meiji Sampler renders a 1080×1080 video alongside the audio. No external tools like ffmpeg are required — encoding is built in.

What the video includes:

* a scrolling waveform for the full duration of the bounce
* channels color-coded by sample type, matching the mixer output history display
* CRT-style post-processing (screen curvature, bloom, scanline flicker, subtle burn-in)
* a spinning Meiji Sampler logo in dot-matrix style
* H.264 video at 6 Mbps + AAC audio at 192 kbps

The video soundtrack uses the same post-PerformFX master audio as the master WAV. Its channel waveforms are still drawn from the pre-master-FX channel captures so the visualizer can show individual channel activity.

The format is square (1080×1080) and intended for sharing on Instagram or other social platforms. The video is written to the same output folder as the WAV files.

Video rendering is background work — Meiji Sampler stays usable while it encodes.

<Info title="video-performance">
  Meiji Sampler supports several levels of hardware GPU acceleration.

  To confirm hardware acceleration enabled, check `Settings → General`.

  Exporting video is a slow but worthwhile process.  Be patient and let the export complete.
