…n and stereo media `frame` gets `--crop`, `--zoom` and `--ids`, `strip` accepts comma separated times and `--crop`, and `inspect --pops` finds parts of the picture that change in one frame between still frames. `include_media_dir!` gets a `stereo` option that keeps both channels of embedded audio.

- Around line 857-883: Update the `args.ids` label-rendering flow so that when
`args.crop` is set, selected labels are drawn in crop coordinates with the crop
origin offset while preserving render scale; keep `FrameResult.elements` limited
to the selected elements and ensure their labels remain visible in the cropped
PNG.

Keep --ids labels visible in cropped frames.
When --ids and --crop are both set, the code keeps intersecting elements, draws labels on the full frame, and then removes pixels outside the crop. A container whose ID label is outside the crop is therefore reported in FrameResult.elements but is not visible in the PNG. Render the selected labels in crop coordinates, translating by the crop origin while preserving the render scale.

A single frame that differs from both neighbours while they match is a flash. Continuous motion changes the same blocks in consecutive frames and is not reported. A change of more than 30% of the picture is a cut and is not reported. Repeats in the same region (a counter, a blinking element) are grouped into one warning with a count.
Note
hello-world(900 frames) scans in about 1 s and gives 9 grouped warnings for its frame counter text, instead of one warning per tick.Important
--zoomrenders the whole frame, so the command refuses sizes above 16384 px per side (the Skia GPU surface limit) and asks for a smaller zoom.Tests
