VideoFrameCountNotSupported (Unable to determine video frame count)
Error while reading frames, unable to determine frame count and duration. Exception: [UNKNOWN]
The video asset is missing required metadata, which makes it impossible to continue parsing. This may be due to a formal spec violation, or simply an unsupported variation of the format.
Verify that the frame count is correctly reported in the asset's metadata. Create a new deliverable in accordance with our delivery specifications and attempt redelivery. Consult with your tool manufacturer or Netflix representative if the issue persists.
