Offline rendering (HQ renders)
Re-render recorded videos via .bat files or the command line.
Offline rendering lets you re-render a recorded camera move. You can output higher resolution and/or higher FPS.
It works by saving the camera motion to a USD file. Then Open Brush can replay that motion later.
Enable camera path saving
Set "SaveCameraPath": true in your config. See The Open Brush config file.
What files you get
When you record a video with SaveCameraPath enabled, Open Brush writes extra files. On Windows, you’ll see a batch file next to the video in Documents\Open Brush\Videos.
Example:
Untitled_13_00.mp4
Untitled_13_00.HQ_Render.batRe-render using the Windows .bat
Double-click the .bat. Pick an option from the menu.
Open Brush will:
Launch
Load your sketch
Render the video
Exit
Higher quality settings can make the framerate choppy. Don’t wear the headset during the render.
“No Quick Load” option
The “No Quick Load” option forces a full load. Use it when your render finishes before the sketch fully loads.
Render a saved camera path from the command line
The camera path is saved in ASCII USD (.usda). If you have other USD tools, you may be able to edit it.
To render directly:
Video camera paths vs Camera Paths tools
These are different concepts:
Camera Paths tools create a path that Open Brush records.
Video camera paths are the saved motion data used for offline re-rendering.
The saved .usda path can be combined with USD exports. That can recreate camera motion in other pipelines.
