The File-based analogy to pre-blacked tape – A highly versatile online mastering workflow
To use VMM in your workflow, insert content as its ready to your “blacked file”. Once the final video, audio segment or closed caption track is inserted, the file is complete. There is no need to export or consolidate. The workflow really is identical to working with pre-blacked tape but without tape’s limitations.Creating VMM can be significantly faster than real-time but similar to tape, you can have a library of VMM on disk and simply copy one to your workspace, which lends even more efficiency and VMM enhance accuracy by functioning as a preset for the file specification.
VMM is a popular workflow for Cinedeck customers:
- VMM allows users to create a pre-set structure for each show
- VMM helps eliminate human errors that wreak havoc on show deliverables that need to be the same for every episode
- VMM can be added to over time as content is ready
- VMM mean that system crashes do not require the encode process to start again from the beginning
Working with Cinedeck’s blacked files for delivery versioning during post finishing
Today, almost all program deliverables are file-based; and while there are definite benefits to file-based workflows, there are limitations as well. Most efficiency limitations for file-based workflows stem from the inability to change the master flat file once it’s been exported or rendered. Take the simple example of different slates for different customers. For every slate change, you need to re-export the entire program AND you need to QC each file.
With Cinedeck’s File-based Insert Edit, we’re improving the efficiency of file-based workflows by applying the capabilities of tape. Create a library of VMM – Virtual Mastering Media – that is analogous to a library of pre-striped black tapes. Since VMM are pre-striped black “files”, you only create your VMM library once. Thereafter you simply copy the VMM you need for your project to your local work-space. In addition, creating a VMM is faster than real-time. Depending on codec and bandwidth, it can be as fast as 1/10th real-time.
Insert your program to a VMM to create the master file and copy the VMM for as many deliverables as are required and insert the appropriate slates. Deliverables with multiple slates can be completed within minutes, not hours, because File-based Insert Edit allows you to simply drop-in the new slate to a finished flat file. Not only do you save time in the exporting process for each successive slate change, you also save the time that you would have devoted to QC-ing each file.
Note: Cinedeck VMM is a workflow leveraging File-based Insert Edit technology. Insert-edit can be used with any pre-existing files for supported codecs, resolutions and wrappers.
