[JIL] Growing File Workflow with Adobe Premiere Pro v.6.0
As stated in earlier chapters of the user manual, just:in linux supports growing file workflows with Adobe Premiere Pro. A workflow overview and important considerations to keep in mind can be found below.
Generally, all supported container types in just:in linux are written in an “open” or “growing” format. However, it is essential to note that Adobe Premiere Pro officially only supports selected codecs for growing files within an MXF wrapper. For more detailed information on this topic, please refer to the following Adobe link: "Growing Files”: Supported file formats
Supported Codecs for growing files within an MXF wrapper
just:in linux supports the following MXF-based codecs for growing files in Adobe Premiere Pro:
AVC-I Class 50/100
XDCAM HD422
The MXF based workflow is officially supported by Adobe Premiere Pro, as stated in their documentation.
Supported Codecs for growing files within a MOV container
just:in linux supports the following MOV based codecs for growing files in Adobe Premiere Pro:
ProRes422, Proxy, LT, and HQ
The workflow based on the MOV container is not officially supported by Adobe Premiere Pro; however, it functions flawlessly.
Important Settings in Adobe Premiere Pro
Please ensure that you set up Adobe Premiere Pro correctly when working with Growing Files:
Preferences
Please ensure that the "Refresh growing Files Every X seconds" setting is configured to “30” seconds or to a higher value. This recommendation is provided by Adobe and has proven to be the most suitable duration for maintaining a stable and efficient workflow. Customers typically opt for “30” or “60” seconds. Additionally, it is necessary to enable the "Automatically refresh growing files" option. You can locate these settings in the Adobe Premiere Pro “Preferences” pane by selecting the “Media” option.
Closed Caption data and Markers
Please note that when working with growing files, Closed Captions data and Markers are inaccessible, as Adobe Premiere Pro reads this data only when the file is closed.
Workflow Example
To illustrate the growing file workflow, let's initiate a recording using the “XDCAM HD422 Capture Preset” and capture video data to a shared storage location.
Once the recording has started, please wait for a few seconds before importing the growing file into Adobe Premiere Pro and loading it into the timeline.
Please take note that the file name within the Adobe Premiere Pro Project Bin will be displayed in italics, indicating that it is a growing file.
The editing process can now start, as the file will be continuously updated in the background. The editor can easily extend the file within the timeline by using drag-and-drop (Trimming). Once the file has updated itself, based on the specified media refresh value previously set in the Adobe Premiere Pro Preferences pane, move the cursor to the end of the timeline to extend/trim it accordingly.
After the recording is complete, the file within the Project Bin folder will revert to the default font style, indicating that it is no longer a growing file. At this point, the timeline entry can be extended once more to accommodate the final updates.
