recent Sora2 The ability to create a combination of acoustics, which is rapidly popular after the launch, often has the effect of making the picture false, but it may sometimes also have the impression that:
It's clear enough, it's smooth, but sometimes it's still fake
It's like a perfect simulation, but it doesn't feel like it's been recorded on camera。
The reasons for this are:AI VideoIt's all about..elementAnd the real video contains..Physical law + Photographic language + human intent.
So, when generating videos, some detail supplementing techniques are needed to stabilize more authentic videos with an AI video tool like Sora2。
Photons: unified “time, weather and material logic”
In all of the "false" sources, it's not possible to find outMistakes are the most deadlyI DON'T KNOW. AI MAY HAVE LEFT THE SUN TO THE RIGHT, BUT THE SHADOW TO THE LEFT; OR THE STREET IS WET, BUT THE REFLECTION IS FLAT. THE BOTTOM LOGIC OF THE REAL PICTURE IS THE "CAUSAL CHAIN OF LIGHT" — WHERE THE SUN IS, WHERE THE GROUND IS WET, WHETHER THE AIR IS MIST, AND HOW THE MATERIALS REFLECT。
Recommendations
- Clear time frame (morning, golden hour, night)
- Specify light direction and color temperature
- Weather determines reflection and colour saturation
- Reflectors such as “wetland surface” “metal” “glass”
Prompt Example:
In a golden hour on the streets of the city, the sun shines from behind the right side of the picture, and the ground is slightly damp and luminous as it has just rained。
There is a mist in the air, a lower contrast in far-off buildings and a reflection of the evening sun in glass windows。
The person walks in a warm light, the shadow is in the same direction as the light, and the whole color is warm。
A city stoned at gold hoour, sunlight coming from the back-right, wet effective only returning the light.
A bright list of problems in the air.
A person walks through the scene, shadows sign with the light time, over the warm and finemic.
Handheld lenses: entry of traces of “human operator”
Real video is almost never completely stable. Even if filmed with clouds, there will be small breath swings and a slight rise and steady。
THE "PERFECT STABILITY" CREATED BY AI CAN BE SEEN AS FALSE AT FIRST SIGHT. SO WE'RE GOING TO MAKE A LITTLE BIT OF HUMAN IMPERFECTION。
Recommendations
- ADD A SLIGHT DITHER (RANGE 0.8% ~ 1.2%)
- Keep "stable-stable" inertia when the lens moves (approximately 0.3 seconds)
- focus occasionally moves slightly back to the main body (focus hunting)
** Prompt Example:**
The scene of the interview, which was taken with a hand-held camera, was slightly shaken up and down。
The cameraman's breathing caused a change in the pacing of the picture, with the focus being on occasional deviations from the person's speech before being automatically pulled back。
The whole is stable but non-mechanized, preserving a real human sense of hand。
A handhold interviewed scene, bright vertical micro-shake as the operator breaks.
The funus Drifts pretty much away from playing spiech, then mostly resturns.
Overall stable yet organized, conviving a human-held camera feel.
3 Deep and Focus: Let's have a visual logic
OUR EYES ARE NOT ALL CLEAR, OUR ATTENTION IS ALWAYS SHIFTING. IF EACH FRAME IS CLEAR, IT LOOKS LIKE ANIMATED。
Deep of Field and Rak Focus are the most effective “real signals”。
Recommendations
- Simulate the smooth transition of Focus from the Foreground Background
- specify focal length (35mm or 50mm) and aperture (f 2.0~2.8)
- controls the focal time of approximately 2 seconds, using natural curves (ease in-out)
** Prompt Example:**
cameras use a 50 mm lens, arctic f/2.0。
The focus is on the eye of the prospective person at the start of the lens, and in two seconds the focus is slowly drawn to a distant bus station。
When the context is clear, the outlook becomes soft, and the light is wide-eyed。
Camera with 50mm lens, apreture f/2.0.
Over 2 seconds, rack Focus Saint.
The background becomes clear as the foreground softly blacks, bokeh highlights take a cat-eye share.
4. Optical defects: making the lens slightly imperfect
Perfect images are often not credible. Real lenses can produce weak dark angles, colour differentials, dizziness and even sensor noise。
These little flaws, like "Fingerprints of the Real World."。
Recommendations
- DARK ANGLE CONTROLLED AT 5%~8%
- allows light flares in highlight
- Keep dark light noise, unmistakable texture
** Prompt Example:**
THE FOUR CORNERS OF THE PICTURE HAVE A SLIGHT DARK ANGLE OF ABOUT 51 TP3T, AND THE LIGHT SOURCE OF THE UPPER LEFT CORNER FORMS A DIM LENS LUMBER。
The high contrast edges are thinly coloured and the dark is slightly granular noise, but the details remain clear。
The overall optical sense is real natural。
Slight 5% vignette around cops, a soft lens flore from the top-left light time.
Minor chromatic aberration on high-level edges, but poorly prepared.
Overall images feel normally.
MICRO-ACTIONS: BREAKING THE "PERFECT POSTURE" OF AI
THE AI CHARACTERS ARE OFTEN TOO FLUID, TOO PRECISE, AND THERE IS NO SUCH "MINORITY" MISTAKE. BUT IT'S THESE IMPERFECTIONS THAT MAKE PEOPLE MORE REAL AND LIVE。
Recommendations
- Add "Slight correction" to action
- Simulation of "reaction chain": disturbance → compensation → recovery
- We'll have to match the face with the body
Example:
One man walked through the crowd with coffee and was slightly hit in the back cup。
He's unconscious to hold the cup with his other hand and smiles are harmless。
The surface of the liquid was fine, and calm was restored after one second。
A man carrying Coffee gets lightly burned in a Crowd; the cup lights lightly.
He apparently sets it with his other hand and formulaely.
Tiny ripples form on the coffee's sunface, setting after about a second.
6. Material authenticity
THE MOST COMMON PROBLEM WITH AI GENERATION IS THAT ALL MATERIALS ARE TOO CLEAN. SKIN LIKE PLASTIC, CLOTHES LIKE STICKERS. THE REAL WORLD IS FULL OF DETAILS: TEXTURE, WEAR, REFLECTION, DUST。
Recommendations
- Clear description of material type and texture (clothes, metals, glass)
- Give the surface state (old, sand, scratches)
- Make sure the light is "validating" these senses
** Prompt Example:**
On the 4 p.m. street, a young woman stood in the sun waiting for her friend。
The sun is irradiated from the top right of the picture, with an angle of about 35 degrees, to form natural warm light。
She was wearing a light-mite needle knitted top, soft fabric, clear fibre texture and fine wrinkles
The jeans are thick and have slight wear marks on the knee
(b) Deep brown leather bags with slightly old surfaces, small creases and reflecting light on their shoulders
Her skin has natural pores and light oil, and the sun forms a small dispersion through silk on her cheeks
The window in the background shows her blurry reflection, with a slight high-light scroll on the edge of the glass
THE COLOUR IS WARM (ABOUT 4800 K) AND THE OVERALL EXPOSURE IS NATURAL, AND THE LIGHT INTERACTS WITH THE MATERIAL IN A VERY DELICATE WAY。
A young woman stands on a city set at 4 p.m., coming from the upper right at a 35° angle.
She wears a light beige knitted sweeter with vision fiber texture and soft wrinkles,
paed with brightly born soldiers with subtle fading around the knees.
A dark brown side bag hangs on her shoulder, showing natural circumstances and specular highlights along the stupes.
Her skin depends on the power and a genre of her; sunlight diffuses only through her hair, making sure that it's clear that she's safe.
Beside her, a gals shop window provides a safebred silhouette, with specular glints slinging as the camera moves.
Colorado is around 4800K, overtly warm and natural, with convincing physical-light intaction that feels full-time.
7. Environmental power: wind, air, particle resonance
When the wind blows out, it should be more than just head-starting. Clothes, dust, flags and even dust in the sunbeams should be followed。
THE PHYSICAL UNITY OF THE REAL WORLD IS OFTEN IGNORED BY AI。
Recommendations
- Specify wind speed and direction
- Describe the delayed reaction of clothing, hair
- Let the dust float with the wind and be visible in reverse light
Example:
The breeze passed from left to right, with the person ' s long hair tectonics and a slight delay in swinging the shoulder belt。
The dust floating in the air and sunlight form visible beams and move in the same direction。
A gentleman blows left to right, laid his way, shoulder strip swinging with light play.
Floating must parties catch the sunlight beams, moving consistently with the wind direction.
8. Camera logic
THE VIDEO GENERATED BY AI TENDS TO IGNORE THE INTENT OF THE PHOTOGRAPHER. BUT THE MOVEMENT OF THE REAL SHOT IS NOT RANDOM, BUT RATHER WANTS TO SHOW THE AUDIENCE。
Recommendations
- The altitude is about 1.6 meters
- Use "Push-Stand-Stand-Silver" structure
- ♪ The future holds back ♪
Example:
The camera moved slowly from right to left at eye height。
Foregrounders occasionally block images and add layers。
Five seconds will be set for the lead, and then the end will be with the roadman。
Camera tracks right to left ate level.
Occidental passersby the rame, adding depth.
At 5 seconds, the shot sets on a media close-up, ending with a natural occult.
Microstory: give the picture “a reason”
EVEN MORE BEAUTIFUL, IF THE PERSON HAS NO PURPOSE, IT'S LIKE AI'S POSER. EVEN THE SIMPLEST ACTIONS — WATCH, SHELTER, HEAD-UP — ARE CREDIBLE WHEN THERE ARE CAUSES AND CONSEQUENCES。
** Prompt Example:**
The girl waits for the bus at the weather station, and her cell phone alerts are two minutes away。
She looked at the watch, looked up, the bus came and splattered, and she took a step back。
The car stopped and she confirmed that it had not fallen and then got in the car。
A girl waits at a bus stop on a clocky day; her phone hands, "bus in 2 minutes."
She checks her watch, looks up; as the bus splashes toward her, she steps back.
After it stops, she plans to make sure she didn't forget her umrrella, then boards.
10. Retention defects
The trueness of the documentary is often the result of little defects that the naked eye cannot detect. Slight film particles, rolling shutter tilts, motion blurs, these details break the "Ai."。
Example:
a slight rolling shutter tilts in a fast smoothing lens
The image is a bit of a film particle, and there are traces of microcompression on the edge but the details are still readable。
The whole color is slightly saturated, and the documentary quality is maintained。
During a fast pan, bright rolling-shutter skeptics.
You know, I'm not sure if you're going to do this, but I'm going to do it.
Colors are subtly detached for a documentary tone.
Conclusion
Sora2 and the power of the AI video tool is that it simulates everything, but the key to "real" is..limitation- To give it rules, physics, inertia, mistakes, it's like humans. Don't pursue perfectionSeek imperfect logicI DON'T KNOW. YOU NEED TO LOOK AT THE SHADOWS, THE LENSES TO BREATHE, AND THE WIND TO BREATHE. WHEN ALL OF THIS IS REASONABLE AND APPROPRIATE, THE VIDEO GENERATED BY AI BEGINS TO BE “TEMPERATURE”。
