1970s film look

1970s car on a coastal road with film grain and strong halation and flare.

Convincing 1970s look, with grain, halation and warm period colour on a vintage coupe along a coastal road.

Film grain look, vintage grading and lens flares hold up consistently (contrast with Kling 3.0 Turbo, which failed this same prompt).

Genuine period grain, warm color timing and lens halation, not clean digital.

Genuine period look: grain, warm color grading, halation around the sun.

Genuine grain and lens halation, not a generic clean render.

Convincing 1970s look with grain, halation and period colour on a coastal road. Cuts from a front view to a rear tracking shot at about 4.3 seconds.

Warm 1970s grade and period car on a coastal road with halation near the horizon; the grain is light.

Correct period grading and halation, but grain is milder than authentic 1970s film stock.

Warm color grading and period car/setting read as intended, but the image itself is clean digital capture with no real film grain or lens halation. Verified directly against an extracted frame.

FAILURE MODE: defaults to a clean modern digital look, same as Seedance 2.0 on this prompt. No period-accurate grain or halation.

FAILURE MODE: defaults to a clean modern digital look. No period-accurate grain or lens halation, despite an otherwise stable, well-rendered shot.

FAILURE MODE: defaults to clean modern digital look, the requested 1970s grain/halation barely appears.

Warm color grading and lens halation land, but the image stays sharp/clean digital rather than true grainy period film.

The car's orientation flips mid-shot from driving away (rear view) to oncoming (front view, headlights visible) with no cut -- verified via frame extraction comparing an early and mid-clip frame: confirmed, a severe continuity/physics break.
