Whip pans, devices, the observed hidden-camera feel

Three special camera effects, each written as timing and placement rather than a name.

The whip pan: name both subjects. Subject A is at rest by about 0.3 s; then comes the blur; subject B comes to rest by about 1.4 s, framed at the same size as A. A whip shorter than about 0.8 s reads as a plain cut. If it fails, fix the swing's timing first and the performance second.

Devices (crash zoom, Dutch angle, dolly zoom, rack focus) only when the treatment asks for them, usually one per short shot. Give each its position, its timing, the frame it starts on, the frame it lands on, and a hold long enough to read.

• A crash zoom, planned in advance, is the single lens change a shot may contain: say, from 84° down to 47° in about a third of a second (0.35 s).

• Write a Dutch angle as roll in degrees: tension sits around 8–15°, a comic-book tilt around 15–25°. The camera stays on its side of the line.

The observed, hidden-camera feel, where the treatment wants it [best available, not yet validated; written for Seedance 2.0]. Three things together:

1. a soft foreground object covering about a fifth to a third of the frame;

2. haze in the air between lens and subject;

3. a far vantage on 8–12°.

Change the foreground object between beats; keep the vantage.
