# Avid's Requirements

{% hint style="warning" %}
This guide is independent of Mimiq, and is only about getting Media Composer deployed successfully. Assisting with Media Composer workflow issues beyond the scope of Mimiq support may require [Professional Services](https://docs.hedge.video/general/purchasing/professional-services).
{% endhint %}

To use Media Composer successfully, you must adhere to Avid's system requirements and implement performance optimizations on each team member's workstation.

Here's a short list of references directly from Avid:

* [Media Composer System Requirements](https://kb.avid.com/pkb/articles/en_US/Knowledge/Media-Composer-System-Requirements)
* [Computer Optimization Guides – Mac and Windows](https://kb.avid.com/pkb/articles/en_US/Knowledge/en367983)

However, we've compiled a list of tried-and-true optimizations so you can quickly elevate your current Media Composer environment to Avid's requirements.

{% hint style="success" %}
You must complete all optimizations on each workstation before reaching out for support.
{% endhint %}

***

### 1. Use a qualified combination of your operating system and Media Composer

When Avid successfully tests a version of Media Composer against a specific version of an operating system, Avid declares that combination `qualified`.

Use Avid's documentation to find the qualified combination that is best for you and your team:

### 2. Update your operating system and Media Composer to the latest possible qualified combination

It's highly probable the latest version of Media Composer won't be qualified for the *latest* version of an operating system. However, Media Composer may be qualified to run on a more *updated* version of the operating system you're currently using.

{% hint style="danger" %}
With rare exception, *do not* update Media Composer or your operating system while working on a Project.
{% endhint %}

***

### 3. Connect your computer to the network using a cable (hard-wired)

Connect over Ethernet or Fibre Channel. Do not use Wi-Fi as your workstation's primary network connection.

***

### 4. Disable Fast Scrub

`Settings > User > Timeline > Use Fast Scrub:` DISABLED

Disabling Fast Scrub results in a significant reduction of [`SFPlayConsumer::Execute TIMEOUT` exceptions](#what-are-sfplayconsumer-execute-timeout-exceptions).

***

### 5. Adjust Media Composer's Audio Settings

`Settings > User > Audio >` ...

{% tabs %}
{% tab title="macOS" %}

* `Play Buffer Size in Samples:` 1024 (could be as low as 256)
* `Tool Buffer Size in Samples:` 1024 (could be as low as 256)
  {% endtab %}

{% tab title="Windows" %}

* `Play Buffer Size in Samples:` 12288 (could be as high as 16384)
* `Tool Buffer Size in Samples:` 12288 (could be as high as 16384)
  {% endtab %}
  {% endtabs %}

Adjusting Media Composer's Audio settings results in a significant reduction of [`SFPlayConsumer::Execute TIMEOUT` exceptions](#what-are-sfplayconsumer-execute-timeout-exceptions).

***

### 6. Increase the Amount of Video Memory Used

[Media Composer caches playback to RAM. The more memory you have installed on your workstation, the better your playback experience will be.](https://kb.avid.com/pkb/articles/en_US/How_To/Correct-interactive-frame-cache-or-Media-Cache-settings-in-Media-Composer)

You can increase the amount of memory Media Composer uses to cache playback here:

`Settings > Site > Media Cache > Video Memory`

Then adjust these settings in `Video Memory`:

* `Desired Video Memory (GB):` set to the desired amount (default: 2 GB)
* `Enable Playback Video Frame Cache:` ENABLED
* `Enabled FX Editing Video Frame Cache:` ENABLED

{% hint style="success" %}
Since the amount of available RAM varies from computer to computer, we can't say how you should set `Desired Video Memory`. It's best to increase or decrease the amount of memory by GBs, then test for any improvement in Media Composer (e.g. playback, scrubbing, exporting, etc.)
{% endhint %}

## Additional Performance Optimizations

### For macOS

#### 1. Remove OpenIO\_VirtIO.acf from Avid Media Composer.app‌

{% hint style="success" %}
Using Blackmagic Design hardware for video playback? Skip this step.
{% endhint %}

Starting in Media Composer 7.0.4, Avid packaged this plug-in with Media Composer – `OpenIO_VirtIO.acf`. Media Composer's installer doesn't let you choose whether to install this or not, so you must take these steps to remove it manually:

1. Quit Media Composer.
2. In Finder, locate the Avid Media Composer application bundle (e.g. `/Applications/Avid Media Composer/AvidMediaComposer.app`).
3. `Control-Click` on AvidMediaComposer.app and select `Show Package Contents`.
4. Go to `../Contents/SharedSupport/AVX2_Plugins`.
   * Note: depending on the version of Media Composer, this folder could be `../Contents/SharedSupport/AVX_Plugins`.
5. Locate the `OpenIO_VirtIO.acf` file. Hold `Option` then drag a copy of it to your Desktop. (Your mouse pointer will change into a plus sign inside a green circle.)
6. Delete `OpenIO_VirtIO.acf` from the Avid Media Composer app package.
7. Relaunch Media Composer.

Removing `OpenIO_VirtIO.acf` results in a significant reduction of [`SFPlayConsumer::Execute TIMEOUT` exceptions](#what-are-sfplayconsumer-execute-timeout-exceptions).

#### 2. Rename your Mac's Computer Name to remove any characters with diacritics.

[Media Composer becomes unpredictable when a Mac's `Computer Name` contains characters with diacritics (e.g. á, é, í, ö, ü).](https://docs.hedge.video/questions#when-i-open-a-project-why-do-i-get-this-error-file-project-name-.avp-not-found)

Take these steps to change your Mac's `Computer Name` in macOS:

{% embed url="<https://support.apple.com/guide/mac-help/change-computers-local-hostname-mac-mchlp2322/mac>" %}

#### 3. Eliminate All Other Performance Inhibitors on Your Mac or Local Area Network

1. [Do not use Wi-Fi as your computer's primary network connection.](#3.-connect-your-computer-to-the-network-using-a-cable-hard-wired)
2. Configure your Mac's Energy Saver settings so your Mac doesn't go to sleep, and none of your disks spins down. Possible Energy Saver settings to modify include:
   1. `Computer Sleep:` Never
   2. `Put hard disks to sleep when possible:` DISABLED
3. Disable the screen saver on your Mac.

### For Windows

#### 1. Use the `BaseAnalyzer` in the Avid Collect Suite app to detect and fix any performance inhibitors in Windows.

1. [Download](https://kb.avid.com/pkb/sfc/servlet.shepherd/document/download/0696e00000SgmhFAAR?operationContext=S1) and install [Avid Collect Suite for Windows](https://kb.avid.com/pkb/articles/en_US/troubleshooting/Avid-Collect-Suite-for-Windows).
2. Launch Avid Collect Suite, then click `CHECK CONFIGURATION`.
3. In the `BaseAnalyzer` dialog, click `Verify All`.
4. Choose `Failed` from the dropdown menu.
5. Double-click any 🔴 item in the list, then click `Fix`.
6. Click `Fix` until the button’s disabled or the `Reason` is `passed`, then click `Cancel`.
   * After clicking `Fix`, Avid Collect Suite may tell you: \
     `Depending on the changes made it may be required to reboot the system.`
7. `Fix` as much as you can, then restart Windows.
8. Once Windows is back up, go back to Step 2 and repeat these steps.
   * You may notice Avid Collect Suite re-lists certain items as 🔴 once again. Avid Collect Suite is working as expected. Once again, `Fix` as much as you can.

#### 2. Complete your Media Composer setup using the [Computer Optimization Guide](https://avidtech.my.salesforce-sites.com/pkb/articles/en_US/Knowledge/en367983?retURL=%2Fpkb%2Farticles%2Fen_US%2FKnowledge%2FWindows-11-Guide\&popup=true) that matches the version of Windows you're using.

## Questions

### What are `SFPlayConsumer::Execute TIMEOUT` Exceptions?

[`SFPlayConsumer::Execute TIMEOUT`](https://duckduckgo.com/?va=e\&t=hq\&q=SFPlayConsumer%3A%3AExecute+TIMEOUT\&ia=web) means some part of your system is too slow for Media Composer to achieve playback. If you open `Tools > Console` in Media Composer, you'll find these exceptions are logged quite frequently in the background, even with standard operations like playback or scrubbing.

### Why is my Project / Bin getting slower (and slower) to open over time?

The `Unity Attic` folder is too big.

Zip and archive the existing `Unity Attic` periodically, then Media Composer will regenerate a new one.

{% hint style="info" %}
It may be best if all team members are out of the Avid Project before archiving the `Unity Attic`.
{% endhint %}

### Why do my Bins show `???` as the owner instead of my Team Members' Computer Name?

‌Someone renamed or moved that Bin, and Media Composer isn't showing the Project's current state. Refresh the Project in Media Composer from your location, and you'll see the current owner of each Bin.

* ‌MC 2021.x and newer: `Bins > 🍔 > Refresh`
* ‌MC 2018.12.15: `Project > 🍔 > Refresh`
