Understanding Dolby Vision XMLs
Sometimes your encoding partners report encoding fails to you, but there's no warnings or errors shown in Metafier. In the example below, you will see that Metafier DOES NOT CHECK THE L1 VALUES on a shot-by-shot basis. However, it may provide some clues, though.
Here's an example:
Solutions to consider
In the XML file, there are only three shots for a full length feature. Check your timeline to ensure that there are shot breaks for every shot on the timeline. You must have at minimum, L1 data analyzed for every single shot on the timeline.
After you have determined that the timeline is cut up correctly, re-analyze any shots that are missing L1 trims.
