Depth Map Video Generator
Turn a short video into a grayscale depth video. Processing stays in your browser and uses your device GPU when available.

Stable short-video output
Depth Anything V2 Small estimates each frame, while temporal smoothing reduces brightness flicker and resets automatically at scene cuts.
Browser compatibility
Chrome or Edge with WebGPU is fastest. Other modern browsers use a slower WebAssembly fallback when supported.
Why use a depth map video?
A depth sequence separates scene geometry from color and texture. It gives AI video workflows a cleaner signal for relative distance, occlusion and motion while prompts or reference images control appearance.
Preserve spatial structure
Keep the foreground, background and object boundaries easier to distinguish when rerendering or changing style.
Guide motion over time
Consistent depth frames can help downstream models follow scene layout, parallax and camera movement with less drift.
Reuse one geometry pass
Use the exported sequence as a depth condition, mask or starting point for depth of field, fog, compositing and new-view workflows.
How to create a depth map video
Upload a short video
Choose an MP4, WebM or MOV file. Only the first 10 seconds are processed.
Choose speed and detail
720p and 24 FPS provide the best output. The 24 FPS mode analyzes at 12 FPS and creates intermediate depth frames for smoother motion.
Process and download
Keep this tab open while the browser estimates, smooths and encodes the depth frames.
Depth map video questions
What is a depth map video?
It is a sequence in which pixel brightness represents relative distance from the camera. A common convention is brighter for nearer areas and darker for farther areas, and this tool lets you invert that range.
How is a depth video used in AI video generation?
Compatible workflows can use it as a geometry condition alongside a text prompt or reference image. The depth sequence guides layout and motion, while the other inputs define subject appearance and style.
What can I do with the exported depth sequence?
Typical uses include video rerendering, style transfer, ControlNet-style depth guidance, masks, depth of field, fog, compositing and experimental new-view generation.
Is this tool free?
Yes. The free mode runs locally on your device and does not use Z-Image credits.
Why is the first conversion slower?
The browser downloads and prepares the depth model once. Later runs can reuse the cached files.
Is this metric depth?
No. This release produces relative depth for visual effects and masks, not real-world distance measurements.
Does the output keep audio?
No. A depth map is an analysis pass, so the exported video is silent.
