Topographic flow guide
Keep your work
Everything is made in your browser, and nothing is uploaded. The PNG and the video are standard range (SDR); neither is HDR.
| Button | What you get |
|---|---|
| Save PNG | The frame as aikizi-topographic-flow.png, at the frame's size on screen times the screen's pixel density, up to twice. |
| Record video | One run as aikizi-topographic-flow.webm, at 30 frames a second and at the same size as the PNG. A browser that cannot record WebM saves aikizi-topographic-flow.mp4 instead. See WebM, MP4 and MediaRecorder. |
A PNG is the frame at the moment you press. Once a run ends the frame holds still, so to keep a moment halfway from A to B, press Replay and then Save PNG while the lines move.
A video always lasts about seven seconds, unless you stop it: the run plays first, and the finished map holds for the rest. A faster Flow speed leaves a longer still end.
The browser picks the video format before it records, trying WebM first. See format check. When it can record neither, the line under the buttons says so and nothing is saved.
The page keeps only the pictures you added, on this device. Reloading it opens them again (the sample pictures if you added none) and brings back the Relief map preset.
