Engine settings were unreadable: every experimental knob carried a paragraph
about cost figures, sampler caveats and failure modes, so nobody read any of
it. The hint is now ONE sentence saying what the setting does, and the
paragraph moves behind a collapsed "Details" link — still the only place some
of those numbers exist, just not in the way of the checkbox.
cut_opening_frames also learns MiniMax H3. It could never engage there: H3's
anchor is a keyframe condition row rather than a pinned latent prefix, so the
t2v guard read every H3 scene as anchorless, and its video latent sits on a
5k+2 grid an arbitrary cut cannot land on. On H3 the frames now come off the
head of the DECODED batch instead — exact to the frame — with the latent's
audio stream cropped by the same proportion of time, because audio decodes
from this node's LATENT output and would otherwise start N frames early. The
latent keeps its full video stream (off-grid the moment it is cut) and the
scene report says so.
Fixes a latent bug on the way: extra streams were cropped on dim 2 with the
video stream's frame count. On H3 dim 2 is the stereo channel and time is
last, so that would have cropped the audio to mono and left its duration
untouched.

The two-pass shift regrew the frames it dropped, and the invented ending
consistently came out with worse or missing movement — not worth paying
steps for. What is left is the part that works: generate the scene exactly
as normal, anchor pinned at full strength the whole way, then cut the
opening off the finished clip. Nothing is regrown, so the scene comes out
that much shorter and the audio is cropped to match.
Six knobs collapse into one INT, cut_opening_frames (0 = off), in the
Editor under Chain Sampler ▸ Timing & Seed rather than Experimental.
Gone with the shift: the mid-schedule split, the rewind re-noise
(_renoise_to_sigma), the tail refill modes, the fresh-audio reset, and the
schedule_context/continue_from_state plumbing that existed only so a split
scene would not re-time the sampler inside each half.
second_pass is untouched — it never used any of that machinery.
