we never built a set. we never left the green screen.
no location scout, no vfx team, no roundtrip to a comp artist.
green screen in, finished shot out, right inside your timeline.
this is shoty. let's make it real.
stop rerolling a whole kling 4.0 clip to fix one thing.
edit mode changes only what you name and holds the rest of the scene.
one line locks the audio and the camera.
prompt below.
remove the crowd of passers-by from video1. keep the music and the camera unchanged.or remove something:replace the red car in video1 with a vintage green motorcycle. keep the dialogue, the music and the camera unchanged.copy-paste:
source: fal.ai/kling-4what edit mode can touch: expressions, movement, camera position, background, style, the cast, the set, single elements.keep the music and the camera unchanged.the lock line is the trick:
one nano banana still is now a full 3d set.
an agent rebuilds it in blender pass by pass, and your camera moves through real geometry instead of a guess.
loop prompt below.
prompt:
look at the attached image. rebuild it as a blender scene. pass 1: block out the main shapes. pass 2: materials. pass 3: lighting. after every pass, screenshot the viewport, compare it to the image and fix the biggest mismatch. use poly haven assets where they fit.
then render your start and end frames from the set and feed them to seedance, kling or veo. both frames come from the same geometry.

what set would you build first?
stop running minimax h3 reference shots on 4-step turbo.
references ride every step. the comfyui docs say keep turbo off or push toward 25.
5 settings from the official guide below.
4. native quality is 0.98 mp, about 1344x768. exactly 1.0 mp goes over the cap
5. there is no negative prompt. it runs at cfg 1, so write what should be there instead
frames snap to 17k+5 at 24fps. 124 frames is about 5s

stop giving kling 4 only a start and an end frame.
it takes up to 10 keyframes across one 30s shot.
one nano banana grid fills them all.
3 steps below.
note: kling 4.0 flash maxes out at 20s and doesn't list keyframe control. the full model does 3 to 30s with up to 8,000 tokens of prompt.

which beat breaks first for you?
same seedance 2 clip. over 5x the price.
that is what one builder found routing one model through different api resellers.
the numbers and a 3-step check below
step 1: find what the model maker charges per second on its own platform.
step 2: divide your reseller's per-second price by that number.
step 3: if it lands near 2x or more, ask what you get for it: editor, queue speed, one bill, credits that expire.
markup is not automatically a scam. you can be paying for one login and a good editor.
just make it a choice, not a default.
prototype through the cheapest door, render finals where the tooling actually helps.
