1.Download and unzip the 2 files:
 
•Exporter7th.prm
•Importer7th.prm

2.Place these in C:\Program Files\Adobe\Common\Plug-ins\7.0\MediaCore.
 
Admin privileges are required to write to this folder.
 
If this subfolder does not exist, just create it first.
 
If installing over previously installed plugin version, preferences may not transfer correctly.  It is best to delete the Adobe Media Encoder preferences file (typically under Users\[USERNAME]\Documents\Adobe\Adobe Media Encoder\[VERSION]\Presets\PresetTree.xml) and restart Media Encoder.

1.Download and unzip the 2 installation bundles:
 
•Exporter7th.bundle
•Importer7th.bundle

2.Open Terminal (as Administrator) and navigate to the directory where you unzipped.  Example:
 
cd /path/to/extracted/plugin/files

3.Remove quarantine flags:
 
xattr -d com.apple.quarantine Exporter7th.bundle
xattr -d com.apple.quarantine Importer7th.bundle

4.Copy files to the Adobe MediaCore Directory:
 
cp Exporter7th.bundle /Library/Application Support/Adobe/Common/Plug-ins/7.0/MediaCore
cp Importer7th.bundle /Library/Application Support/Adobe/Common/Plug-ins/7.0/MediaCore
 

Copy these to /Library/Application Support/Adobe/Common/Plug-ins/7.0/MediaCore. Admin privileges are required to write to this folder.  If these subfolders do not exist, just create them first.

Use Extensions settings to enable and disable Apple and third-party extensions, and select extensions to include in the Share menu.  Extensions, such as Markup, add extra functionality to apps, the Finder, and the Touch Bar.  To change these settings, select Apple menu > System Settings, click Privacy & Security in the sidebar, then click Extensions on the right.

To verify the installed plugin version:

1.Open Adobe Media Encoder

2.Add any piece of content to the queue, then open the queue item's Export Settings (by clicking the blue text in the Format column of that queue item)

3.Choose 7thSense from the format list.

4.Select the Video tab, then click About Codec
 

Importing

1.Open Media Encoder

2.Browse in the Media Browser to a folder that contains a .7th or .sth image sequence.
 
If you need content to test with, download and unzip this low resolution .7th 4:2:2 sequence: DOWNLOAD
 
You should see thumbnails generated for each frame in the Media Browser, which confirms that the import plugin is present.
 
HOWEVER, do not attempt to add a sequence to the Queue from the Media Browser, because this method does not support "Sequences"!  AME will only allow you to import a single individual frame here.
 

3.INSTEAD, click File --> Add Source.

4.Browse to a folder that contains a .7th or .sth image sequence.

5.Single click just the FIRST indexed image file, ensure that the Sequence checkbox is checked, and Open.
 

6.Open that Queue item's Export Settings (by clicking the blue text in its Format column).

7.Click the Source tab (upper-left corner), and drag the playhead around a bit.  You should see the images rendered.

Exporting

1.Follow similar steps as written above to add ANY source movie/image sequence supported by Media Encoder to an After Effects Composition (and .7th sequences are now among those possibilities with our Import plugin installed.)

2.Open that Queue item's Export Settings (by clicking the blue text in its Format column).
 

3.Choose Format --> 7thSense.

4.Click the blue text beside Output Name to edit the export path and file naming.  Remember that you are produced a sequence of images, so you should first create a new folder that will hold ONLY the new images, then enter that folder, and there set the base name of the image files will use.   Upon export, AME will automatically add zero-padded frame index to whatever base name you choose.  It is generally best practice to match the folder name and base name, but with an "_" added at the end of the base name (after which AME will add the frame index upon export.)

5.Under Video codec settings, choose a .7th subformat.

6.At this point you can just hit OK, unless you wish to intentionally change further parameters like scaling or frame rate.   Note if you are converting FROM an image sequence TO an image sequence, it's value doesn't have to match the reality of the fps this clip is actually produced to play at.  Just leave that setting as is and frames will enter and exit 1:1 with no rate conversation

7.Click Play button on the Queue
 
If the export produces any extraneous files in that sequence folder (e.g. ".xmp" files), you need to delete them before attempting to bring the resource into DeltaServer.

Importing

1.Run After Effects and Start a new Project,

2.Click File --> Import --> Files.  Browse to a folder that contains a .7th or .sth image sequence.
 
If you need content to test with, download and unzip this low resolution .7th 4:2:2 sequence: DOWNLOAD
 
NOTE: Similar to Media Encoder, the Media Browser pallet in After Effects  does not support Import of image sequences.  After Effects also does not render thumbnails for .7th frames.

3.Single click just the FIRST indexed image file, ensure that the checkbox Import7th Sequence is checked, as well as Create Composition, and then Import.
 

4.You should now see the .7th footage and a composition created based on that footage in the Project bin.  Open that Composition and you should see the frames rendered in the Composition pallet.
 

IMPORTANT CONSIDERATIONS:

•If you are working with sequence with color bit depth beyond 8-bit, it's important to increase the project's working color depth in File --> Project Settings --> Color to "16 bits per channel" (the default being "8 bits per channel").

•AE will automatically applies some "Interpret Footage"settings to every given imported clip (and the Composition created based on those initial clip settings).  For image sequences, it's important to review that both the Frame Rate and Color Space settings are appropriate.  .7th files do not contain color space metadata, only the color bit values.  So it's important to communicate with the media producer what color space the data was written to be interpreted as (e.g. Rec709).    Also beware that After Effects is a color-managed workspace (configurable in File --> Project Settings -->Color).  This means that all footage is conformed from its interpreted color space to the working color space for preview, composition, and ultimately export.  
 
You can bypass color management for a given clip by checking Preserve RGB in its Interpret Footage -->Color tab.  This is generally what you should do if using AE for simple edit/format convert purposes.    Notice how different (and more correct in this case) the same .7th image sequence looks from above after checking Preserve RGB.

Exporting

1.Follow similar steps as written above to add ANY source movie/image sequence supported by After Effects to a Composition (.7th sequence are now included among those possibilities with our Import plugin verified above.)
 
If you'd like to test conversion of TGA to .7th, download and unzip this low resolution TGA 24-bit RLE sequence: DOWNLOAD

2.Be sure to review Project Settings, and Interpret Footage settings for that clip (as discussed deeper in the Importing guidance.)

3.Select the composition in Project pallet, then in the top menu bar choose Composition --> Add to Adobe Media Encoder Queue.   From here, just follow the instructions given earlier in this guide for Exporting in Adobe Media Encoder.
