I?m also interested in the movie_passthrough feature.
I believe the answer to Ted?s question below is high res capture does not use
the movie_codec parameter. That?s I think part of the idea - free the CPU from
having to do the encoding of the higher res stream. Instead the captured movie
is created directly from the frames sent from the camera.
Disclaimer: just starting to learn this feature. Please correct/clarify as
needed :)
Here is the documentation on the feature:

Subject: [Motion-user] movie_passthrough: Possible on RPI camera?
Message-ID: <[email protected]>
Content-Type: text/plain; charset="utf-8"
Wondering if it?s possible to use the motion_passthrough feature on a raspberry
pi camera? (Meaning the actual RPI camera, not just any camera attached to an
RPI)
The documentation says it works with ?some V4L2 cameras? and the netcam_url
parameter must be used - so that makes me feel it?s not possible - but not
really sure.
Here?s the documentation:
https://motion-project.github.io/motion_config.html#movie_passthrough
<https://motion-project.github.io/motion_config.html#movie_passthrough>
Thanks for any info

I believe here is the answer to Ted?s question from the feature documentation:
?..when motion is detected, the high resolution images will be captured and
processed into the movie file without going through the decode/encode
processing."
