<table><thead><tr><th width="262.57142857142856">Parameter</th><th>Explanation</th></tr></thead><tbody><tr><td><code>&#x26;crop</code></td><td>Changes the aspect ratio on the publisher side, but lets you pass an integer value to represent a percentile cropping value.<br><br>So, <code>&#x26;crop=10</code> will reduce the width by 90% and <code>&#x26;crop=-10</code> will increase the aspect ratio. The assumed base aspect ratio is 16:9.</td></tr><tr><td><code>&#x26;debug</code></td><td>Sends live debug log data to a remote server.

## Mix-Minus (`&mixminus`)

`&mixminus` (alias `&mm`) enables N-1 (mix-minus) routing when used on a director or co-director link. Each guest receives a custom audio mix that includes all other participants but excludes their own audio, preventing self-return echo loops.

This is a director-side feature: the director's browser creates and manages the per-guest mixes. Add `&mixminus` to the **director** URL, not to guest links.

Note: `&mixminus` prevents a guest from hearing their own voice back, but does **not** prevent speaker-to-mic acoustic bleed in rooms where guests use external speakers without headphones. For that, see [`&noheadphones`](https://github.com/steveseguin/vdo.ninja/blob/gitbook/source-settings/noheadphones.md).
