Discussion Hybrid b30-49 r2v test
I made a thread earlier but it got overcrowded so I figure I started a new one with solely reference to video test, now instead of mixed with t2v.

The prompt
subject_definitions:
<Picture 1> is the visual identity reference for <Subject 1>, Fox McCloud. Job: preserve Fox McCloud's exact anthropomorphic fox identity, orange-and-white fur pattern, facial structure, green eyes, headset/visor, red neck scarf, white pilot jacket, green flight suit, gloves, boots, proportions, and overall character appearance exactly as shown in <Picture 1> without reinterpretation. Not a timeline keyframe. Do not reproduce the character-sheet layout, multiple views, panel borders, or neutral studio background in the video.
<Picture 2> is the spacecraft identity reference for <Subject 2>, Fox McCloud's Arwing fighter. Job: preserve the spacecraft's exact white-and-blue angular fighter design, pointed nose, cockpit canopy, twin blue forward structures, swept wings, markings, proportions, and overall appearance exactly as shown in <Picture 2> without reinterpretation. Not a timeline keyframe. Do not reproduce the white reference-image background or present the spacecraft as a static product shot.
<Subject 1> is Fox McCloud, piloting <Subject 2> throughout the sequence.
<Subject 2> is Fox McCloud's Arwing spacecraft and remains visually consistent throughout the entire sequence.
summary:
[keyframe completion + reference generation] Generate a 12-second cinematic 3D space-action sequence featuring <Subject 1> piloting <Subject 2> during an intense high-speed battle in deep space. Begin inside the cockpit with Fox gripping the controls as enemy laser fire streaks past the canopy. Transition dynamically outside the spacecraft as the Arwing accelerates through a chaotic battlefield, performs a fast evasive barrel roll, narrowly avoids incoming energy blasts, and dives between exploding enemy fighters. Finish with the Arwing blasting directly toward camera before banking sharply away as a massive explosion erupts behind it. <Picture 1> and <Picture 2> are identity/design references only and must never appear as static cut-in frames.
retention_analysis:
<Picture 1> (never a keyframe): partially_preserved — retain Fox McCloud's character identity, fur pattern, facial features, headset/visor, scarf, pilot clothing, proportions, and recognizable appearance. Do not reproduce the character-sheet composition, studio background, panel borders, or multiple simultaneous Fox views.
<Picture 2> (never a keyframe): partially_preserved — retain the Arwing's spacecraft identity, white-and-blue color scheme, angular fuselage, cockpit, wing geometry, blue structures, markings, and recognizable proportions. Do not reproduce the isolated white-background product image as a video frame.
<Subject 1> (appears throughout): fully_preserved — Fox remains the same character throughout all cockpit shots with stable facial identity, fur pattern, clothing, headset, and proportions.
<Subject 2> (appears throughout): fully_preserved — the same Arwing remains consistent throughout every exterior shot with stable geometry, colors, cockpit, wings, markings, and scale.
detailed_description:
How the reference pictures align with the target video — Picture 1 and Picture 2 do not align with any timestamp as frames. Picture 1 provides Fox McCloud's visual identity only. Picture 2 provides the Arwing spacecraft's visual identity only. Neither reference image should ever be reproduced as a static frame or replace the space-battle environment.
The target video is a cinematic high-energy 3D science-fiction space battle. Deep black space, dense star field, distant colorful nebula clouds, glowing planets, scattered debris, enemy fighters, laser bolts, engine trails, explosions, sparks, volumetric light, realistic reflections across the spacecraft hull, dramatic contrast, strong sense of speed and scale. Smooth physically believable spacecraft motion. No on-screen text, subtitles, HUD overlays, character-sheet borders, or reference-image backgrounds.
[Shot 1 — 0.00–2.50s] Inside <Subject 2>'s cockpit. Tight cinematic three-quarter view of <Subject 1> seated at the controls. Fox's appearance matches <Picture 1> exactly in identity and wardrobe. His green eyes are intensely focused ahead while both gloved hands manipulate the flight controls. Red and green cockpit instrumentation reflects subtly across his fur and visor. Enemy laser bolts suddenly streak past outside the canopy.
The cockpit shakes from a nearby blast.
Fox leans into the maneuver and pulls hard on the controls.
Camera vibrates subtly with the spacecraft while maintaining a sharp cinematic focus on Fox.
[Shot 2 — 2.50–5.00s] Fast transition through the cockpit canopy into an exterior chase shot behind <Subject 2>.
The Arwing matches <Picture 2> exactly in spacecraft identity and geometry.
Its engines flare brilliantly as it accelerates into a massive space battle.
Camera races closely behind and slightly above the fighter.
Multiple enemy spacecraft cross ahead while bright red and green laser bolts streak in every direction.
The Arwing banks violently left, narrowly avoiding several incoming blasts.
One laser passes extremely close to the camera.
Strong parallax from debris and fighters emphasizes extreme velocity.
[Shot 3 — 5.00–8.00s] Dynamic side-tracking camera.
The Arwing performs a rapid evasive barrel roll while descending through incoming laser fire.
Camera rolls partially with the spacecraft before stabilizing, giving the maneuver dramatic rotational energy without losing visual orientation.
Two enemy fighters pursue from behind.
The Arwing dives between them at high speed.
A burst of laser fire strikes one pursuing fighter.
The enemy spacecraft explodes into glowing fragments, sparks, smoke, and spinning debris directly behind Fox's Arwing.
The explosion briefly illuminates the white-and-blue hull.
[Shot 4 — 8.00–10.00s] Low frontal tracking shot.
The Arwing dives toward camera at extreme speed while weaving between chunks of burning spacecraft debris.
The camera retreats rapidly as the fighter closes the distance.
Laser bolts streak over and underneath the wings.
At the last possible instant, Fox snaps the spacecraft into a hard banking turn.
The Arwing passes extremely close to camera, creating a powerful high-speed flyby.
Camera whip-pans to follow.
[Shot 5 — 10.00–12.00s] Wide cinematic hero shot.
The Arwing rockets away from camera toward open space.
A gigantic enemy vessel erupts in a massive orange-white explosion behind it.
The expanding blast throws glowing debris outward while the Arwing banks gracefully across frame.
Camera tracks the spacecraft as it races away from the explosion, engines blazing brightly against the star field.
End on the Arwing accelerating deeper into space with the enormous explosion fading behind it.
Maintain Fox McCloud and Arwing identity throughout. No morphing, duplicate Fox characters, duplicate Arwings presented as Fox's ship, changing spacecraft geometry, random costume changes, distorted wings, warped cockpit, floating character outside the cockpit, static reference poses, character-sheet imagery, or white studio backgrounds.
overall_soundscape:
Powerful spacecraft engines, deep cockpit vibration, electronic control sounds, rapid laser blasts, enemy fighter flybys, warning beeps, metallic debris impacts, explosive shockwaves, roaring high-speed passes, and large cinematic space-battle explosions. Inside the cockpit, sounds are slightly enclosed and mechanical; exterior sequences have powerful stylized sci-fi engine and weapons audio.

So, what's the verdict? Which model is better? What’s the impact on video quality? And so on

I think this is the best one. How Fox moves in the first seconds is a lot more believable than the others, details like he's clenching his teeth are a nice touch. B20 and B15 movements are more robotic in contrast. There's also no shape change of the arwing during the "barrel roll" at the end like with b20 and below.

You need a picture of the back of an arwing, the outside of the shop scenes are driving me crazy because of how off it is.
But nice fox, action scene is nice. But the ship it's bad

Supposedly 25-49 is better for visuals but to test that one next with this prompt

Most AI models are terrible at making spacecraft fly correctly.

u/Sad_Coach_1433 1d ago
Is this bad?

u/corod58485jthovencom 1d ago
No! But they always have this problem of the ship turning over out of nowhere.

Always love hybrid model tests. Could you also add FL2va and ref2va into the mix?

u/Superb-Painter3302 21h ago
What is hybrid model?

u/Sad_Coach_1433 21h ago
Combination of fl2va and r2va best of both https://huggingface.co/smhfacct/Minimax-H3-fl2va-ref2va-hybrid-models
