- A mark on the very end seeks a moment short of it; while a clip is marked the end of the item
neither closes the player nor steps the queue, and Plex's auto-skip waits.
- Plex: Escape and Back peel what is over the picture (info, up-next, the countdown) before the
clip; Back under a dialog is the dialog's; no range opens while the length is unknown.
- YouTube: the focus goes back to the scissors the user can see, else the player; the panel keeps
its name, Loop and focus when the view is maximised or restored under it.
- A typed time stays in its field until taken, then shows where it landed; unreadable stays marked
invalid; a decimal comma is read (ui/TimecodeField, the editor's fields too).
- RangeTrack: a drag is its pointer's, a cancelled drag reports final, an adornment sits beside the
slider, a caller-chosen focus ring (amber on the clip strip). CropFrame: a drag is its pointer's.
- The editor's remove-cut is a real button at the cut's foot; a segment's keep toggle sits over the
cut's hit area.
The handles reach 10 px into the frame from every side; a frame at its minimum on a small picture
(the Downloads editor at 800 px: 41 x 23) was then nearly all handle - 74 of its 920 px still moved
it. Below 64 px on its shorter side the frame takes 12 px corners and 8 px edges: 262 px move it.
The press is held back from the page (no text selection, no play / pause underneath), which also
kept it from focusing: after a drag the arrows still went to whatever had the focus before, and
Escape did not reach the frame. The press now focuses the frame or the corner it grabbed (an edge
focuses its frame).
An optional crop in clip mode: a Crop toggle puts a frame on the picture (free, 16:9, 9:16 or 1:1;
the whole picture stays the default). The frame is sent in fractions of the box it was drawn in,
with that box's shape; the worker fits the real picture into the box by its display aspect (sample
aspect and rotation aware), drops the part over the bars, and crops first in the filter chain. A
frame covering the whole box is no crop at all, and one off the picture is refused by name.
The crop frame is a ui primitive (CropFrame) shared with the video editor, keyboard-operable.
YouTube: the wide side panel shuts while clipping and comes back after; maximised, the clip panel
docks in the stage. Plex: the picture sits above the clip panel so the frame lies on it.
