You know, it might be easier to interpret the footage, then use “remember interpretation”. It doesn’t look as if your situation is covered in the interpretation rules.
From the help:
To apply Interpret Footage settings to several footage items:
1. In the Project window, select the item whose footage interpretations you want to apply.
2. Choose File > Interpret Footage > Remember Interpretation.
3. Select one or more footage items.
4. Choose File > Interpret Footage > Apply Interpretation. After Effects applies the footage interpretation options to the selected items.
Hope that helps,
Steve
