Titles and your Timeline
If you have received the above warning in your Dolby Vision XML, it may be related to the placement of Titles on your HDR color timeline.
In the case where you want to verify if a shot on your color timeline may have an issue with a title card, such as titles on a separate video track or an un-flattened timeline, a quick way to verify this is by using a Text Editor.
Using an XML Editor
Open the XML in a text editor, locate the shot by searching the Unique ID
Check the L1 data. Usually you may find the average Lum is very close to the Minimum Lum.
Two ways to fix:
- Go back to the grading timeline, flatten the timeline, re-analyze the shot, re-export the XML.
- Load the XML and master file into a Dolby Vision enabled editing software, re-analyze the shot.
