PPro Beta & UXP operation history

Premiere Pro

Hi,
Unlike ExtendScript, PremierePro Beta & UXP leave history of operations in ‘History’. This allows users to ‘Undo’. This is good!
I think it would be even better if we could do ‘beginUndoGroup() ~ endUndoGroup()’ like AfterEffects ExtendScript. What do you think?

Hi!

If you would like do or undo a group of actions, you can consider add multiple actions to compoundAction before executing it.

Example code:

const ppro = require("premierepro");
const filterFactory = ppro.VideoFilterFactory;
const newComponent1 = await filterFactory.createComponent(
      "PR.ADBE Gamma Correction"
    );
const newComponent2 = await filterFactory.createComponent(
      "PR.ADBE Extract"
    );
// assume you have defined videoComponentChain from valid trackItem and project 
let success = false;
try {
      project.lockedAccess(() => {
        success = project.executeTransaction((compoundAction) => {
          var action1 = videoComponentChain.createInsertComponentAction(
            newComponent1,
            2
          );
          var action2 = videoComponentChain.createInsertComponentAction(
            newComponent2,
            2
          );

          compoundAction.addAction(action1);
          compoundAction.addAction(action2);
        }, "Add multiple effects");
      });
    } catch (err) {
      log(`Error: ${err}`, "red");
      return false;
    }

By doing so, undo action will remove both added effects at the same time. [Another reason we switched to action-based setting APIs!]

Thanks for the feedback!
