Using the AAF Encoder

Example Workflows

Avid Integration Guide

Note: For help configuring each action, open the Inspector and click on the M icon in

the upper right corner to display context help.

Watch—Monitors a file folder for an incoming media file.

Flip #1—Configured with the AAF Encoder, this Flip action is configured to create a

high-resolution in XDCAM HD 4:2:2 (or other selected format-for supported formats,

see Overview). My leaving the Master MOB-ID and Source MOB-ID blank the AAF

Encoder action auto-generates the asset and associated Master MOB-ID.

Avid Web Services are used to check the asset into to the Interplay database. The

master video asset (Avid-compatible MXF OP-Atom) and associated audio files are

written direct to shared storage. Two additional files are written-an XML file that

contains format attributes, and an AAF file that initializes check-in to Interplay. Once

check-in is complete the files are no longer required. Vantage provides a checkbox to

automatically delete these files from storage.

Edit-While-Ingest/Frame Chase editing can be performed on this asset.

Identify—Configured to extract the Master MOB-ID from Media Properties of the

XDCAM output media attachment of the preceding AAF Encoder and assign it to a

variable. Use this Master MOB-ID variable for downstream actions.

Flip #2—Configured with the AAF encoder and H.264 Proxy codec, the Flip action

generates a proxy file and writes it to shared storage. To associate this resolution to the

same asset as Flip #1, bind the Master MOB-ID variable passed from the preceding

Identify action to this encoder's Master MOB-ID field.

Flip #3—The Flip action uses the Keyframes encoder, configured to extract a keyframe

from the media file at 00:00:01:00 and create a thumbnail JPEG file. (Of course, any valid

frame size and timecode can be specified.) The keyframe can be nicknamed

avid_headframe, for example, and stored in a share.

Synchronize—Delays downstream action execution until all preceding actions are

complete.

Notify—Configured with the Avid Notifier, use the Set Headframe function to associate

the JPEG file created from the Keyframe encoder with the master asset in Interplay for

viewing in Interplay Access. To associate the Keyframe to this asset bind the Master

MOB-ID value passed from the preceding Identify action to the Master MOB-ID field in

the Set Headframe dialog.

Processing a News Feed with XML Workflow

The purpose of this workflow is to process news feeds and their associated metadata

file as a single job and check them into Interplay for editorial.

When a video file and associated XML file are identified by the Watch action and

Associate action, a job is started. The workflow extracts the metadata and populates a

label, creates a key frame file for use in Interplay Access, and transcodes the media file

into both high-resolution and low-resolution files, checking the asset into Interplay.
