01. Importing Footage

In a new project, double click open the Media Manager and import the tutorial clips. Make sure to import them into the same Media Bin. During the import of the clips, PFClean has analysed the clips and any metadata that may be available in the file headers to automatically assign a suitable standard format to the clips.

02. Reviewing The Format Standard

Click the Media Admin button to open the Media Admin. The Standard column lists the format standard assigned to the clips. Click on of the nutcracker clips to select it. This will display more detailed information at the bottom of the window.

The Standard format drop down list lets you change the standard assigned to the clip. Note that only standards that fit the clip’s resolution and metadata will be available for selection. Fields like Frame rate and Pixel aspect cannot be changed directly, as they are defined by the standard. Changing the clip’s standard to PAL 576 16:9, will change the Pixel aspect accordingly.

For video standards, the Deinterlace field becomes available and you can choose how PFClean should handle the fields of the clip.

03. Using Standards to Direct Clips

Return to the Workflow Manager by clicking the wfm button button. Clips in your project can be directed into specific nodes based on their standard format.

Select Media Bin 1, then create a Workbench node. Double click the Workbench to open it. You can see from the thumbnails in the worklist that all our 4 clips are available in the node. Return to the Workflow Manager.

Open the Select a standard menu. The menu lists the format standards of all clips in the node. Select Full Aperture 2K from the menu. This means that only the clips of this standards will remain in the Workbench node. All other clips are now available through the Media Bin’s second output connector. Create a Telerack node and connect it to the free output.

Open the Telerack’s Select a standard menu and select PAL 576. Then create another Telerack node and connect it to the Media Bin’s third output.

As there is only one standard left in the Media Bin’s third connector, this standard has been automatically selected for the new Telerack node.

Changing a Clips Format Standard

Double click the Media Manager and open the Media Admin. If it isn’t already selected, click the PAL 576 16:9 clip and change its format standard back to PAL 576. Then return to the Workflow Manager.

Both nutcracker clips are now flowing into the same Telerack node. As there are no more PAL 576 16:9 clips in the Media Bin, the newest Telerack node is empty. You can change the standard for one or both of the nutcracker clips back to PAL 576 16:9 to flow clips back into the other node.

04. Custom and Unknown Standards

custom_standardsPFClean ships with a number of format standard definitions that the application uses to determine which standards are suitable for clips. You can find these definitions in the file formatStandards.xml in PFClean’s installation directory.

If PFClean is unable to match a clip to a standard, the clip’s thumbnail will contain a cyan square in the top left corner.

For these cases it is possible to add your own custom standards to be used in the application.

The ‘User-defined file formats’ section of the PFClean manual explains how to add to PFClean’s list of available formats. You can open the manual in your web browser by clicking the ? in the top left corner of the PFClean window.
