To encode a video or audio item, add the item to the encoding queue in Adobe Media Encoder, and then select encoding presets or create your own custom settings. You can instruct the application to start encoding after you add an item to the queue, or you can tell the application to wait until you decide to start encoding.
The encoding process
Add an item to the encoding queue - Drag video or audio files into the queue in Adobe Media Encoder.
Encode the item using presets - Select formats and presets from the Format and Presets pop-up menus with the item in the queue. Or choose a preset from the Preset Browser and drag it to any item in the Queue. For more information, see Encode using presets.
Encode the item using custom settings - Select the item and select Edit > Export Settings, and then choose your settings. For more information, see Encode using custom settings.
To start encoding items in the queue automatically (or to turn off the feature), select or deselect the Start Queue Automatically When Idle For option in the Preferences dialog box. For more information, see the Preferences article.
Import items into the encoding queue
- To add video or audio files, do one of the following:
- Drag one more files into the queue.
- Click the Add Source button and choose one or more files.
- Double-click an open area in the Queue panel and choose one or more files.
- To add a Adobe Premiere Pro sequence, do one of the following:
- Choose File > Add Premiere Pro Sequence, select a Premiere Pro project, and select one or more sequences from that project.
- Drag-and-drop a sequence from the Project panel in Adobe Premiere Pro into the queue.
- Drag-and-drop a Premiere Pro project from the desktop on the Queue.
- To add an Adobe After Effects composition, do one of the following:
- Choose File > Add After Effects Composition, select an After Effects project, and select a composition from that project.
- Drag-and-drop a composition from the Project panel in After Effects into the queue.
- Drag-and-drop an After Effects project from the desktop on the Queue.
- Choose File > Stop Current File to stop encoding the current item. Adobe Media Encoder continues encoding the remaining items in the Queue.
- Choose File > Stop Queue to stop encoding all items in the Queue.
Interpret items in the encoding queue
When Adobe Media Encoder imports a video asset, it attempts to determine the pixel aspect ratio, frame rate, and field order for that asset, as well as how to interpret the alpha channel (transparency) information. If Adobe Media Encoder is wrong about any of these characteristics, you can explicitly assign the correct interpretation.
Watch folders in Adobe Media Encoder
You can configure Adobe Media Encoder to look for files in certain folders called watch folders. When Adobe Media Encoder finds a video or audio file in a watch folder, it encodes the file using the encoding settings assigned to the folder, and then exports the encoded file to an Output folder created inside the watch folder.
The Watch Folders panel in In Adobe Media Encoder can be used to add and manage folders. You can add a watch folder in one of the following ways:
- Choose File > Add Watch Folder and select a folder.
- Double-click an empty area in the Watch Folders panel and select a folder.
- Create a folder in Explorer (Windows) or Finder (Mac OS), and then drag it to the Watch Folders panel.
You can see the name of the folder in the left column of the Watch Folders panel after you have created it.
The items added to the encoding queue by the watch folder will be encoded along with other items in the queue when you start the queue.
If you have the “start queue automatically when idle for” preference selected, encoding begins when the specified amount of time has elapsed after the watch folder has added a new item to the encoding queue.
Keep the Auto-Encode Watch Folders checkbox enabled to automatically encode items when they are added to the watch folder.
You can choose a format and preset from the pop-up menus in the watch folder next to the folder name. Or drag a preset to the watch folder from the preset browser.
You can generate multiple outputs with a single operation by using watch folders. For example, you want to generate an AVI movie, and a JPEG thumbnail image whenever you transcode a video asset. Follow these steps to create these files with a single user operation:
Create a new watch folder by clicking the Add Folder button, and then navigate to the folder you just made, “My_Watchfolder.”
Create a new Watch Folder item that also points to the folder “My_Watchfolder,” just like you created in Step 2.
Create a new Watch Folder item that also points to the folder “My_Watchfolder,” just like you created in Step 2 and Step 3.
The preset should be custom and have Export As Sequence unchecked. This will only export the first frame of the video, which is often black.
Still Image Sequences are not supported as source footage through Watch Folders. If a set of still images is placed in the folder being watched, each individual still file will be added as a separate item to the Queue rather than the entire sequence as a single piece of footage.
Save the encoding queue
The encoding queue and all encoding settings are saved automatically when you exit Adobe Media Encoder.
The encoding queue is also saved automatically when a user starts an encode.
Turn off the Preferences > Remove completed files from the queue on exit checkbox if you want to keep completed encoded items in the Queue when you close and restart Adobe Media Encoder.
