Hello
To add a duration column in an EDL using the List Tool in Avid 2021.9.0, follow these steps:
In the List Tool, go to the File menu and select Output.
In the Output dialog box, select the desired output format (e.g., CMX 3600).
In the Columns section, click on the Duration checkbox to add it to the Selected Columns list.
Click OK to save the output format.
Back in the List Tool, select the sequence or clip you want to create the EDL for.
Go to the File menu and select Export.
In the Export dialog box, select the output format you just created and click OK.
Choose a location to save the EDL and click Save.
The resulting EDL should include a duration column for each edit in the sequence or clip.
