Details
Description
The sampled frame size describes the frame as it is sampled. That means it includes the visible frame size, but may also include more pixels so that the value might be larger than the value of the display frame size (which is defined in QC Test Item 0043W).
Definition
Used in Checks, the system shall read out the Sampled Frame Size indicated in the wrapper metadata and check if it matches the expected one specified in the input. Optionally the system may report the value.

Used in Reports, the system shall read out the Sampled Frame Size indicated in the wrapper metadata and report it.

Remarks
In MXF this metadata element is optional. Its presence might be restricted by user profiles.

The sampled frame size can be different from stored frame size due to macroblock or slice size restrictions of the codec.
