Using Contact Sheet: Tag Filtering
In addition to manually choosing the shots with Pick Mode, you can also populate the Contact Sheet Viewer by using tags on shots in the Timeline.
Note: Tag Filtering is available in Nuke Studio and Hiero, but not in HieroPlayer.
The example below shows a simplified sequence that has three tags applied in various ways to different clips. The beginning and end clip are also populating the Contact Sheet Viewer via manual Pick Mode selection.
To start filtering the Contact Sheet by tags, you can simply select which tags and boolean operation you’d like to use.
Clicking the Tag Filter drop down in the Contact Sheet menu bar will display all the tags currently present on the sequence being sent to the Contact Sheet. Here you can also see check boxes indicating the boolean operation.
The two check boxes next to each tag entry have three states:
• Inactive (gray) - this tag is not be used to display a shot in Contact Sheet
• Active (highlighted) ‘+’ PLUS - This tag is being used to include shots in the Contact Sheet and is performing an “AND” boolean
• Active (highlighted) ‘-’ MINUS - This tag is being used to include shots in the Contact Sheet and is performing an “MINUS” boolean
The check boxes make it quick to toggle between the different states and see your changes dynamically update the Contact Sheet Viewer. Note that you can only have one state for a particular tag enabled at a time. For instance if you had a ‘+’ PLUS check box enabled for a tag then clicked the ‘-’ MINUS check box the ‘+’ PLUS state would automatically be disabled and the ‘-’ MINUS checkbox enabled.
Clicking an active checkbox again will disable it, effectively removing that tag from the filtering.
In this simple sequence we’re first going to enable the Tag Filter Pick Toggle button on the left so we can see changes in the Contact Sheet Viewer as we change the tag filtering options. As we have no pre-chosen tags this will effectively show an empty Contact Sheet.
Now opening the tag filter drop down, check the ‘+’ PLUS button next to the Blue tag. You’ll see that three shots are added to the Contact Sheet because they contain a Blue tag.
Now if you check the ‘+’ PLUS button next to the Green tag only two shots are displayed because we are asking the Contact Sheet to ONLY filter and display shots that meet that “AND” boolean. In other words the clips MUST contain both a Blue AND a Green tag. You’ll notice that there is a clip that contains just a Blue tag and just a Green tag that are not displayed.
Now if you click the ‘-’ MINUS button next to the Magenta tag you will only see the one shot which has a Blue AND Green tag but NOT a Magenta one.
Using this simple mechanism it should be possible to filter and display a lot of combinations. For instance if you wanted to see all shots that contained no tags then you could just switch to ‘-’ MINUS on all the tags and you would then see what is left; in this case the two un-tagged shots at the beginning and end of the sequence.
The manual Pick Mode selection and Tag filter selections are persistent, meaning that you can use the Tag Filter/Pick Toggle button to quickly switch between the two modes and see what was last used.
