![]() KP: When working with a filmmaker for the first time (or for the first time in a while) I typically send them my “Deliverables Spec Sheet for Post Sound.” It gives them the preferred settings when exporting assets from Avid Media Composer or Adobe Premiere Pro. I always ensure that I copy the audio into the session audio files folder on import. For more complex projects I will import the AAF into a pre-existing session template using Import Session Data. Pro Tools is set as the default application to open AAF files. For something really simple like a short corporate video mix with just dialogue and music, I’ll just double click the AAF and open it as a new session. PM: How I open AAF files in Pro Tools depends on the complexity of the project. KD: Download and copy to my working SSD, then import and keep the import on AAF tracks at the bottom of the session. GK: With new clients, I ask them to send me a consolidated AAF with 75 frame handles. If it was not, we reject the delivery and the picture edit house needs to re-execute AAF output & delivery. Obviously sample rate, bit depth and timecode rate are interrogated to ensure the AAF output was properly executed. track groupings are correct, music and six not intermingled or “shotgunned" across the entire timeline). Assistants go to work on them immediately to determine whether they meet our turnover specifications (i.e. RC: AAFs are" turned over” by picture editorial and loaded onto our content server. We asked our panel of experts a series of questions and here are their answers for each of the questions in turn… How do you handle AAFs? Most applications for audio and video support AAF and MXF formats moving forward. AAF retains the volume automation and the track names. OMF loses the volume automation and names of the tracks when exporting and importing from one application to another. OMF is supported in a number of applications including AVID and Pro Tools.ĪAF is the newer format and contains more information than the OMF. Open Media Framework (OMF) or Open Media Framework Interchange (OMFI) is a platform-independent file format intended for transfer of digital media between different software applications.Īs we have described above, AAF (and OMF) are used to transfer sequence/timeline information from one application to another. What is the difference between the OMF and AAF formats? It provides for application program interfaces (APIs). It encapsulates HTML and XML content, includes translators, and supports HTML/XML output. It provides a way to “wrap” elements of a project together for archiving. It catalogues an extensive list of audio and video effects with a rich set of built-in standard effects. It allows the combined project in a selected format to be rendered later in the post process. ![]() It allows access to networked content files on remote platforms or storage. It allows users to track the history of pieces of program content from source elements through final production. ![]() It facilitates the cross-platform interchange of metadata or program content. ![]() This allows the content to be described as a media object. The AAF solution has several components: It supports the complex combination of a piece of content and its associated metadata. the AAF format is designed to replace OMFI. For example, a file might contain a 30-minute sequence along with instructions on how to cut it down to 5 minutes … along with an external reference to text reports or still photographs located on a separate system. It can wrap video, audio, data, and even references to external assets along with instructions on how to render this material into a finished program. The Advanced Authoring Format (AAF) is an interchange toolkit and exists to get video, audio and metadata from one system to another. You can consider it as a “Super-EDL,” but actually it is also much more.ĪAF is Open Source, so it’s available to manufacturers for free to implement into their systems. It is a technology designed specifically for digital nonlinear post-production and authoring. What is the AAF format?ĪAF stands for the Advanced Authoring Format. In this article, a panel of experts shares their experiences of using AAFs and OMFs in their professional workflows.īefore we turn to our experts, so that everyone is on the same page, we are going to define what AAFs and OMFs are and how they fit into the post-production workflow. In audio post-production, we often get AAFs or OMFs from the video editor which provide us with the edited audio from the picture edit.
