Location at Launch: The new Media Composer 2021.6 is available in MyAvid Master Accounts, through the Avid Link application itself and from the Download Center. The ability to launch Media Composer 2021.6 software is dependent on the status of a customer’s Upgrade and Support Plan on the date this software version is released. Media Composer 2021.6 was released on June 17th, 2021

Media Composer Notes:

MCDEV-11537 If you intend to use full-frame stereoscopic with an Avid Artist DNxIQ, you may want to remain with Media Composer v2018.12.x until the issues with Stereoscopic support are resolved in a future version.

(MCCET- 2541) When working with Avid Artist DNxIO or Avid Artist DNxIQ, you should disable the Line In recording input (BlackMagic Audio in the Windows OS).

• Avid recommends that you do not install Desktop Video software version 10.10.1 on Media Composer versions prior to v2018.5.1. 
• Avid Artist DNxIO and Avid Artist DNxIQ: If you are using Avid Artist DNxIO, Avid Artist DNxIQ, or a BlackMagic Designs video device, please update to Desktop Video software version v11.0 or higher. If you are using Avid Artist DNxIV and Avid Artist DNxIP please update to AJA software v15.2 or later.
• Qualified Operating Systems: For information on qualified operating systems, see Qualified Hardware and Operating Systems.

Changed in Media Composer v2021.6: The following are new for Media Composer v2021.6:

• Go to Next Event and Go to Previous Event

With this release, more options have been added to the Composer Settings' Move tab. You can adjust the behavior of the Got to Next and Go to Previous Event commands by enabling options in the Move tab of the Composer Settings. You can choose from the following new behaviors

•  
  • When the Composer or Timeline is the active window, the Go to Next Event and Go to Previous Event commands allow you to navigate through audio keyframes.
  • When the Audio Mixer tool is the active window, the Go to Next Event and Go to Previous Event commands allow you to navigate through audio keyframes.
  • When the Audio Mixer tool is the active window, the Go to Next Event and Go to Previous Event commands move based on track selector state when Ignore Track Selectors is disabled.

Bin Status Bar Duration

The Bin Status Bar now displays the total duration of a selection in a bin.

Dragging Clips to a Closed Bin and Closed Folder in Sidebar

With this release, you can now drag clips to a closed bin in the Bin Container Sidebar. Once you drag the items to the closed bin, the bin will open with the dragged items selected. When dragging items to a closed folder, the folder will now auto-expand.

Improved Timeline Scrolling

A new button has been added to the Command Palette. The Timeline Movement During Play button allows you to toggle between different movement possibilities. You can set the Timeline Movement During Play button to the following:

•  
  • Page - moves the position indicator during play until it reaches the end of the visible Timeline.
  • Scroll - keeps the position indicator stationary
  • None - the button is not selectable when set to None

Updated Bin Setting

The option “Save single floating Bin Containers in Workspaces” has been added to the Bin Settings. Select this option if you want a floating Bin Container that is not tabbed or paneled with other tools or Bin Containers to be saved into a workspace.

Workspaces Load Last State

To create a more natural flow across workspaces, Media Composer now loads the last state of a workspace rather than the last saved workspace. This allows you to move between workspaces and return to where you were the last time you left the workspace.
If you want to load the last saved workspace, simply go to the Workspace Bar menu or the Windows menu and select Restore to Saved.

Avid Titler+ Text in Clip Notes and EDLs

A new Avid Titler+ setting allows you to automatically populate the clip note on the Avid Titler+ segment in the Timeline with the Titler+ text.

This provide an easy way to view, search and export Titler+ text in the Timeline. For details, see “Adding Notes to Clips in the Timeline” in the Help.

Avid Titler+ All-In-One Text Box

With this release, you can now start typing with a standard title text box and turn it into a defined paragraph text box by simply resizing its bounding box while in Text mode.

Update to Media Composer | Distributed Processing

Media Composer Distributed Processing allows Media Composer users to offload foreground tasks such as rendering, consolidating, or transcoding to one or more service workstations on the network.
With this release, a number of updates have been included for Media Composer | Distributed Processing. For details on these new options, see Chapter 3 “Distributed Processing Workflow” in the Avid Media Composer | Distributed Processing Administration Guide. 

The changes include: 

•  
  • Mixdown - Media Composer | Distributed Processing DP option is now available for all mixdown windows. 
  • Export - Media Composer | Distributed processing now supports exporting AMA formats (MXF op1a, AS-11, and DPX). You can initiate the export from: 

-  File > Output > Export via Distributed Processing 

-  Right click clip or sequence > Output > Export via Distributed Processing 

-  Right click Record Monitor > Output > Export via Distributed Processing 

•  
  • Media Creation Settings - has 3 new options: “Use this machine as a worker for jobs submitted when possible,” “Automatically check-in sequence sent for render” and “Job Queue”.
  • Email Settings - If you want to receive a notification about the status of completed Distributed Processing jobs, you can select “Enable Sending of Email for Distributed Processing” checkbox in Email settings and specify the SMTP server which will be used for DP email transfer. User authentication for DP SMTP server is not required.

Update to Media Composer | Enterprise 

Two additional functions have been added to Media Composer | Enterprise that allow the administrator to enable or disable user functionality.

o    The additional functions:
Allow Editing - any user that belongs to a group that has this option deselected will not be allowed to modify or edit sequences loaded into the Timeline.

Limitations: The following are known limitations

• Photoshop PSD files are not supported for AMA linking if QuickTime is not installed.
• Some fonts, by their design, are available only in Bold. On the Mac system it can happen that selecting a font does not produce any visual changes. Try selecting “Bold.”
• If you launch a project and receive an “Enable 3rd Party Emulation” warning, even if you select Enable in the warning dialog, you should also perform the following: Select File > Settings and click the Project tab. Click General Settings and select “Enable Bin Sharing on 3rd party storage emulating Avid NEXIS/ISIS.”
• Bug Number: MCDEV-14845. Media Composer | Enterprise Admin tool does not restrict NDI when Media Composer is in software only mode.
• Bug Number: MCCET-3702. Image Quality when adding UHD progressive clips to an HD interlace sequence:
  The process Media Composer uses to mix and match video formats in a sequence is to transform the source clip's frame rate and frame layout to meet the project specifications; the motion adapters are added first, then spatial adapters are applied in order to provide expected playback dimensions.
  For example, if you have a UHD 50p clip that you want to add to a 1080i Timeline, the UHD clip first gets split into 2 separate fields (UHD format), then each field gets independently resized to 1920x540 in HD. The export process puts those resized fields back together into a progressive HD frame but does not maintain the clarity of the original progressive frame.
  Workaround: If you first transcode the UHD progressive clip to HD progressive and then add the HD clip to the interlace sequence, it forces the resize operation from UHD to HD to be done before the split gets into interlace mode. 
• Bug Number: MCCET-3788. You might receive a “clip name is a clip in a multi-essence file that cannot be exported using the specified Embedded in AAF setting” when exporting embedded AAFs with OP1a audio clips.Workaround: Consolidate the OP1a clips to Avid OP-Atom prior to performing the export.
• Bug Number: APPSVCS-723.  The Collab App in MediaCentral CloudUX window does not currently work with Media Composer.
• Bug Number: MCDEV-13604.  You might have issues playing clips containing Media Composer effects in the Baselight User Interface if the Fast Image Access option is enabled in the Baselight plug-in
• Bug Number: MCDEV-12926. (macOS) If you have upgraded to macOS 10.15.4, there is a known issue with local attached RAID storage. The system will hang when running Media Composer or copying large files. This does not happen with earlier versions of the OS. You can read details about this issue in this blog. This limitation no longer exists with macOS 10.15.5.
• Bug Number: MCDEV-12988. (macOS) The AMA Drastic plug-in is not supported with Media Composer v2020.4
• Bug Number: MCDEV-12964. For a faster performance of export audio/video sequences to .mov in 2020.4, please render the sequence prior to export, or disable the GPU fx (in the Render Settings - Current menu)
• Bug Number: MCDEV-12735. Maestro graphics do not appear correctly in the Timeline if your system uses the Radeon video card.
• Bug Number: DEFI-1808. (Media Composer | Distributed Processing) Two clips or sequences will always be created when performing a consolidate or transcode with Media Composer | Distributed Processing.
• Bug Number: MCDEV-11481. Promoting a title from the Title Tool application to Avid Titler+ cannot be performed if it includes a motion adapter.
• Bug Number: MCCET-11796. Larger than 10 bit DPX files might fail to link correctly.Workaround: Go to File > Settings and click the User tab. In the Link Settings, click the Link Options tab and make sure Alpha Channel is set to Ignore.
• Bug Number: MCDEV-11430. Media Tool ignores the “Current project” filtering option and lists media files that are not associated with the current project.
• Bug Number: MCDEV-11197. In some instances, the Interleave option might not appear in the Export As dialog box. If you are performing an Export using the Avid Media Processor, the Interleave option should appear when you choose Stereo, 5:1, or 7.1 Audio.Workaround: If it does not appear, briefly toggle back to the Mono setting, then toggle to Stereo Mix once again. Doing so should reveal the Interleave option.
• Bug Number: MCDEV-8641. (AMD Graphics). Systems with AMD graphics cards might display tearing when performing Full Screen playback.
• Bug Number: MCDEV-9269. (Media Composer | Cloud) After performing a remote download operation on a sequence containing AVC-I 100 remote media, the downloaded media appears as XAVC-I 100.Workaround: Download the entire master clips.
• Bug Number: (macOS).  You may occasionally see the menu bar flash followed by a brief beach ball. To fix this, deactivate “Displays have separate spaces” under System Preferences > Mission Control settings.
• Bug Number: MCDEV-9011. Intermittently, when working with the XDCAM Nablet Plug-in, you might see “Failed to get the sample position from the AMA Plug-in” errors if you have waveforms enabled in the Timeline.
