Test settings

One shared brief

For a future controlled run, submit the same text to both models and keep reference files out of the baseline.

Matched output target

Request 10 seconds at 16:9 with audio. Confirm a common native resolution before generating and record any differences.

First attempts

Keep the first attempt from each model and log failed requests. Record retries separately to measure repeatability.

Comparable delivery

Log the platform, model ID, date, actual settings, wait time and net charge. Alternate which model is submitted first.

Three paired video tests

Each scene shows both model outputs. Use the shared prompt and acceptance criteria to review the pair.

Glass bottle camera orbit

Keep a stationary product stable as its reflections change.

Muse Video · Glass bottle camera orbit

Kling 4.0 · Glass bottle camera orbit

What counts as a usable result?

The silhouette, stopper and liquid line stay consistent.
The camera completes one continuous arc.
Reflections shift without visible glass distortion.

Read the shared prompt

Create a 10-second photorealistic 16:9 video. 0-2s: Frame a single amber glass bottle with a round black stopper on a pale stone block, straight on at table height. 2-8s: Move the camera along a shallow arc to the right. Keep the bottle and block still as soft side light slides across the glass. 8-10s: Hold the three-quarter view with the full bottle visible. Preserve the corners, stopper and liquid level. Audio: quiet room tone. No cuts, lettering or music.

What counts as a usable result?

The face and jacket stay recognizable.
The fingers grip the handle without intersecting it.
The cup finishes upright on the tray and the hand releases it.

Read the shared prompt

Create a 10-second photorealistic 16:9 video. 0-2s: In a quiet cafe, frame an adult waiter in a navy jacket behind a wooden counter, with a white ceramic cup on the left and a cork tray on the right. 2-8s: The waiter grips the handle with their right hand, carries the cup to the tray and sets it upright. 8-10s: Hold as the waiter releases the cup. Keep the face, hands, cup and tray in the same locked eye-level medium shot. Audio: soft ambience and a ceramic tap when the cup lands. No cuts, speech or music.

Kling 4.0 · A florist speaks after a doorbell

What counts as a usable result?

The bell rings as the door opens.
The visible florist says the requested line once after the bell.
The face stays visible and mouth movement follows the speech.

Read the shared prompt

Create a 10-second photorealistic 16:9 video. 0-3s: In a flower shop, frame an adult florist in a green apron beside a closed wooden door, with a brass bell visible above it. The florist opens the door and the bell swings once. 3-7s: After the ring, the florist looks just past the camera and says once, “We open at nine.” 7-10s: Hold on their face as the door settles. Keep one locked eye-level medium shot. Audio: one bell ring as the door opens, then the spoken line over faint street ambience. No other voices, subtitles, cuts or music.

Observations and timestamps pending sample review.

Quality and consistency

Watch each clip from start to finish with sound. Record timestamps for the first visible defect and for the moment the requested action ends.

Instruction following. Check the action order, camera path and final frame.
Continuity. Check the bottle shape, jacket and tray as the camera and subject move.
Motion and image quality. Watch for flicker, unstable framing and objects intersecting during contact.

Audio and reference control

Use the shop scene to check the bell onset, speech order and mouth movement. Listen to the original files at normal speed before inspecting individual events.

For a separate reference test, start with one shared image if both selected endpoints accept it. Evaluate the Kling 4.0 Frames workflow separately when a shot needs a specific ending composition.

Muse Video Prompt Guide

Speed and cost

Waiting time

Measure from submission to a playable result. Record queue time separately when the platform exposes it.

Cost per usable clip

Divide net charges, including charged retries, by the number of clips that meet the acceptance criteria. Report zero usable clips separately.

Measured time and cost are pending. See Muse Video pricing for site plans.

Which model should you choose?

Start with Muse Video if the brief can be described with text or an image and you want to direct sound alongside the shot in the Muse-Video.app editor.

Start with Kling 4.0 if you need to direct a shot with prepared start and end images in the Frames workflow.

For projects that can use either workflow, compare the original outputs against the scene criteria before deciding.

Muse Video vs Kling 4.0 FAQ

Is Muse Video better than Kling 4.0?

The best fit depends on the shot. Use the paired tests to compare specific outcomes such as product shape, hand contact and audio timing. A measured winner requires reviewed outputs.

Will both models use the same prompts?

Yes. The baseline uses the same text, requested framing and sound cues for both models. Model-specific prompt changes belong in a separate test.

How many outputs are planned?

Three scenes and one initial attempt per model per scene, for six planned outputs. Additional attempts can measure repeatability.

Can both models generate audio?

Meta describes native audio for Muse Video. Enable sound in the selected Kling 4.0 workflow if the setting is available. Playback is needed to compare timing.

What if the output settings differ?

Confirm the available settings before submission. Record the actual resolution, duration and aspect ratio for each clip and explain any mismatch alongside the result.

How will speed and cost be compared?

Record submission-to-playback time and net charges per attempt. Calculate cost per usable clip after checking each output against its scene criteria.

Start with one clear shot

Describe the main action, where the camera moves, and what the viewer should hear.
