7.5 The Metadata Editor
7 THE PRO-CODEC MANAGER APPLICATION
The list of presets is ordered alphabetically, and is immediately re-ordered when a new
preset is saved. Empty presets cannot be saved, so the
+ button is not displayed when
the
Metadata Editor is empty.
To delete or remove a preset, hover your mouse cursor over the preset name, and press
the red
X button that appears at the right-hand side of the row. A pop-up window will ask
for confirmation before deleting the preset.
7.5.9 The Metadata Lock Mechanism
It is important to remember that the changes performed in the
Metadata Editor are not
written to the selected file until the
Write to File button is pressed.
If a new file is selected for processing when the metadata of the previously selected file
has been edited (but not written to file), those changes will be lost. A pop-up window will
appear in this case, to warn the user and allow the operation to be cancelled.
Each field in the
Metadata Editor can be protected to ensure that it isn’t modified during
editing. Clicking at the beginning of that field’s row, in the padlock column, will toggle a
small padlock on that row.
Click and drag in the padlock column to lock or unlock multiple tags.
Locked rows will retain the current tag content when clearing, reverting, or importing
metadata from other files or presets. Additionally, when changing the
selected-for-processing file, that row will keep its state. The
Cover Art tag can also be
locked, by clicking on the padlock icon in the lower right corner.
When a non-encoded file is selected for processing, metadata info can also be added in
the
Metadata Editor. The main difference with encoded files is that the Write to File
button is disabled, since this metadata cannot be written to an uncompressed PCM file.
Instead, the metadata in the section will be written to the new encoded file.
