nw.checks#
The checks nw itself ships — a small, honest default menu.
These are the three that need nothing nw does not already shell out to, and they are here because each of them has already caught a real defect in a finished film:
a missing stream — a render that produced a video track and no audio, or an audio track and no video, and returned a path either way;
an encode that stopped early — a ten-minute cut killed by the OOM killer two-thirds of the way through, whose container still reported the full duration, because the container takes its duration from the audio stream. Every duration check passed. Counting frames is what catches it;
a long freeze — a model returning a too-short clip and a
tpadfallback holding the last frame for four seconds, which looks exactly like a deliberate hold until you measure it.
They are registered at import of nw, so they are on the menu. They are
not run by anything: see nw.validation on why validation is placed by
a caller and never assumed.
Every check here is built on nw.inspect, which is the older, direct form
of the same knowledge. That module stays: a caller who wants one typed report
about one shot should keep calling shot_report. These wrap it for callers
who want a selection of checks scheduled and reported together.

- nw.checks.as_path(target)[source]#
The media file a target refers to.
Checks are handed whatever the caller validates. These built-ins want a file, so they accept a path, a string, or anything with a
pathoroutput_pathattribute — and say so plainly when they get none, rather than reporting a clean bill of health on something they never opened.- Return type:
