This Test is a measurement only and includes no read-out of the metadata container duration (e.g. because the metadata has not been set). For read-out please use EBU QC Test Item #0040W (Latest version) .
A measurement of the frame count could be necessary if the metadata "container duration" is not set. In MXF files a way to measure the video frame count is to count the relevant edit units of the MXF file.
