2D→3D Conversion Platform — User Guide
How to turn ordinary 2D videos and photos into glasses-free 3D content, and what every option in the workbench does.
EnglishVersion 2026-10-14 Video & image conversion
1Overview
The platform turns 2D input into an output that a glasses-free 3D display or a compatible player can present with depth:
| Input | Outputs you can choose | What creates the 3D effect |
|---|---|---|
| Video | RGBD video · Multi-view grid video · Quad-screen video (beta) | RGBD → the player uses the depth information to build the view for each eye. Grid → several real viewpoints are packed into one video and the player or display switches between them. |
| Photos | Multi-view grid image · Glasses-free 3D image (switchable view sequence) · Interleaved image · Individual views | Image packages → the player or display selects a view for each eye. Interleaved → the picture is prepared for the lens of one specific display. |
Two families — the one distinction to remember
Depth-based output (RGBD video) carries depth information; the player decides how strong the 3D looks. View-based outputs (grid video, grid and switchable images, interleaved) already contain the finished viewpoints, so the 3D strength is fixed by the settings you choose here.
2Getting started
- Sign in to the workbench. You see your own tasks; administrators also see everyone’s tasks.
- Choose a tab: Video or Image conversion.
- Select your files. You may select several at once — they are uploaded and queued one after another.
- Set the parameters. Good defaults are already in place for each device; the chapters below explain the ones you may want to change.
- Start the conversion. Use Full render for real work and Preview for a quick composition check. Progress appears in the task list, and a Download result button appears when a task is done.
Good to know
- Batches. Files submitted together form a batch. You can download each result on its own, or the whole batch as one ZIP once all of its tasks have finished.
- Cancelling. You can cancel a task while it is waiting or running. If an upload does not finish, the task is cancelled automatically — simply upload the file again.
- Your settings are remembered per device in this browser. Switching device restores the settings you used last for that device; the reset action brings back the device defaults.
- Player requirement. Grid and switchable-image outputs need a player or display that understands the corresponding format. The workbench shows a short notice whenever an option needs the latest player.
3Video outputs
3.1 RGBD video
What it is. One video file that carries two things at once — the normal colour picture and a grey-scale depth map — together with the audio, all on the same timeline.
How the 3D appears. A compatible player uses the depth map to build a slightly different image for the left and the right eye. Because the player does that step, the viewer can usually adjust the 3D strength during playback.
| Advantages | Limitations |
|---|---|
|
|
Extra settings that only affect RGBD: Resolution (recommended keeps the size up to 4K) and RGB video codec (the platform picks the right one automatically when needed).
3.2 Multi-view grid video
What it is. One video file that packs several viewpoints of the same scene into a grid — for example 3 × 3 = 9 views — on a single large picture. Each cell shows the scene from a slightly different position.
How the 3D appears. The player shows one cell at a time and switches or cycles through them, or a lenticular display picks the cells that fit the left and right eye. The viewpoints are already rendered, so the 3D strength is fixed by the settings you choose here.
| Advantages | Limitations |
|---|---|
|
|
3.3 RGBD or grid — which one should I choose?
| RGBD video | Multi-view grid video | |
|---|---|---|
| What it contains | Colour picture + depth map + audio | Several finished viewpoints in a grid + audio |
| 3D strength | Adjustable while watching | Fixed when converting (In-/Out-of-screen depth) |
| Playback device | RGBD-capable player | Grid-capable player or display |
| Typical file size | About the same as the original video | Several times larger |
| Best for | Everyday conversion, previews, depth-capable players | Glasses-free displays, view-switching players, signage loops |
Rule of thumb If you are unsure, convert a short clip as RGBD first — it is the
smallest and most flexible output — and add a grid version only when your playback device needs one.
3.4 Video settings
| Setting | Options | What it does |
|---|---|---|
| Task type | Full render · Preview | Preview produces a fast, lower-quality sample for checking composition. |
| Output type | RGBD · Multi-view grid video · Quad-screen (beta) · Image conversion | Quad-screen returns a ZIP with four videos (one per wall) and is a beta feature. |
| In-screen depth 入屏度 | A scale from 0 to 10 | How far the scene extends behind the screen. Higher = a deeper background. |
| Out-of-screen depth 出屏度 | A scale from 0 to 10 | How far the subject may come towards the viewer. Higher = a stronger pop-out. |
| Resolution (RGBD) | Recommended · Original | Recommended keeps the size up to 4K; Original keeps the source size. Both adapt the picture to 16:9. |
| RGB video codec (RGBD) | H.264 · H.265 | Leave on H.264; the platform switches to H.265 automatically when it is the better choice. |
| Video frame rate | Recommended (up to 30 fps) · Original | Recommended keeps the file small and stable; Original keeps the source frame rate (e.g. 50/60 fps). |
| Audio track | Standard audio track (AAC) · AV3A audio track | Choose AV3A only if your playback device supports it; then also choose the bitrate and channel layout. If the source already uses AV3A, it is kept as it is. |
| View transition mode (grid) | Switchable view sequence · Back-and-forth views | Switchable lets the player choose between wrap-around (跳变) and back-and-forth (不跳变) while watching; “back-and-forth” fixes it in advance. |
| Grid columns / rows (grid) | A grid, e.g. 3 × 3 | The layout of the viewpoints. 3 × 3 is the standard; more cells need a bigger picture and make each view smaller. |
| View image downscale factor (grid) | A factor from 1 to 12 | Shrinks each cell before packing, which reduces the total picture size and the file size. |
8K limit The total picture of a grid video must stay within 8K (7680 × 4320). The
workbench shows an estimate and warns you when it is exceeded — use fewer rows/columns or a larger downscale factor.
3.5 Recommended video settings by content
| Content | In-screen | Out-of-screen | Notes |
|---|---|---|---|
| Interview / talking head | 4 – 6 | 2 – 4 | Keep the pop-out small; faces tire the eyes quickly. |
| Landscape / scenery | 6 – 8 | 5 – 7 | Depth is the message here; check the sky for ripples. |
| Product / close-up | 4 – 6 | 4 – 6 | Centre the product; strong highlights may show slight ghosting. |
| Architecture / interiors | 6 – 8 | 3 – 5 | Straight lines make mistakes visible — preview first. |
| Fast motion / sports | 4 – 5 | 3 – 5 | Prefer RGBD, or a smaller grid; this is the heaviest case. |
| Signage loop on a 65-inch display | 5 – 6 | 4 – 6 | A 3 × 3 grid with downscale 3 is the standard recipe. |
Tuning tips: raise out-of-screen only while the subject still looks comfortable; if viewers report eye strain, lower out-of-screen first. If the picture looks flat, raise in-screen before out-of-screen.
4Image outputs
4.1 Output types
| Option in the workbench | What you receive |
|---|---|
| Multi-view grid image 宫格图 | One view grid plus the 2D picture that was used for the conversion, packed into a single file. |
| Glasses-free 3D image 可切换视点顺序裸眼3D图 | A package with the 2D main picture and two view grids (wrap-around and back-and-forth) so the player can switch the view order. Requires the latest player. |
| Interleaved image 交织图 | A finished picture prepared for the lens of a specific display — show it directly on that device. |
| Individual views only 仅单视点子图 | A ZIP containing every single view as its own image, without a grid. |
What is pre-selected
65-inch display → grid image. 10.1-inch display → grid, switchable and interleaved. 22-inch advertising display →
interleaved only. “Individual views” is always an exclusive choice of its own. If you had selected all three outputs in an
older version, the workbench switches to the new default once and then keeps whatever you choose afterwards.
4.2 Target device
| Device | Pre-selected outputs | Restrictions |
|---|---|---|
| 65-inch display | Grid image | — |
| 10.1-inch display | Grid + switchable + interleaved | — |
| 22-inch advertising display | Interleaved only | Square (1:1) pictures only. The device-specific lens values must be filled in — they come with the device documentation. |
Each device carries its own starting values for the depth parameters; you do not need to set them yourself unless you want a different look.
4.3 Image aspect ratio
- Recommended — crops the photo to the shape of the device’s screen (for example 16:9). Best for filling the display edge to edge.
- Original — keeps the photo's own shape without cropping.
- Custom — you enter a shape (for example 16 : 9 or 1 : 1) and it applies to the whole batch; an individual photo can still be adjusted on its own.
4.4 Core parameters
| Parameter | What it does | Adjust it when… |
|---|---|---|
| Out-of-screen Depth 出屏度 | How far the subject may extend towards the viewer. | The subject should stand out of the screen. Too high feels tiring and can produce unclean edges. |
| In-screen Depth 入屏度 | How far the scene may recede behind the screen. | The picture looks flat and you want a deeper scene without pushing anything towards the viewer. |
| 3D Depth Strength 相机间距 | The overall 3D strength — the strongest single control for how much depth a picture shows. | You want more or less 3D on the same device. Change it in small steps, and leave the value as it is otherwise. |
| View Mode 视图模式 | The order in which the viewpoints are arranged, and therefore how the player moves through them: wrap-around (裂变) or back-and-forth (不裂变). | Your playback device expects one particular arrangement. The switchable image contains both, so the player can also choose at playback time. |
Recommended order 1) choose the device, 2) set the picture shape, 3) set
3D Depth Strength for the overall depth, 4) fine-tune In-screen and Out-of-screen for the
composition. Everything else normally stays at its default.
4.5 Recommended parameters and tuning
| Scenario | Out-of-screen | In-screen | 3D Depth Strength | View mode | Extra advice |
|---|---|---|---|---|---|
| Portrait / people | 3 – 5 | 5 – 7 | slightly below default | Wrap-around | Keep the background soft and the pop-out modest; faces tolerate less than products. |
| Landscape / travel | 5 – 7 | 7 – 9 | default or a little higher | Wrap-around | Great for depth; check a bright sky and switch on the sky protection if it ripples. |
| Product / still life | 5 – 7 | 4 – 6 | slightly below default | Back-and-forth | For plain backgrounds use the flat-area restore option; check text and logos at the real viewing distance. |
| Architecture / interiors | 4 – 6 | 7 – 9 | default | Wrap-around | Straight edges reveal mistakes — convert a preview first. |
| Text-heavy / screenshots | 2 – 4 | 4 – 6 | low | Back-and-forth | The hardest content: keep the depth modest so text stays sharp. |
These values assume the 65-inch display The other devices start from their own defaults;
begin there and adjust in the direction shown above.
4.6 Troubleshooting
| Symptom | What to do |
|---|---|
| The picture looks flat / “2D” | Raise In-screen Depth first, then 3D Depth Strength a little. |
| Eyes feel tired after a few seconds | Lower Out-of-screen Depth; keep the main subject just inside the screen. |
| Faint double edges (ghosting) | Try the other view mode. If it remains, it comes from the display itself. |
| “Requires the latest player” notice | Deliver the grid image instead, or update the player. |
| Conversion fails, or the result will not play | Use a smaller grid or the device-default resolutions; for video reduce the grid size or increase the downscale factor. |
| Upload failed and the task cancelled itself | Refresh the page and upload again — no partial result is kept. |
