Rendering at 4K
As of version 0.9.6.2, Source Filmmaker supports the option of exporting a movie or image sequence at 4K (3840 x 2160) resolution.
If you want to render at 4K, you must set the appropriate command-line startup option before you launch the SFM.
To render at 4K:
- Quit the Source Filmmaker if it's open.
- In Steam, right-click Source Filmmaker, click Properties, click the SET LAUNCH OPTIONS button, and add -sfm_resolution 2160 -w 3840 -h 2160 to your command-line startup options.
- Launch the Source Filmmaker.
You can also use this command-line switch in a command prompt or in a desktop shortcut.
Once Source Filmmaker is running, you will be able to select higher export resolutions via the Export Movie panel; This also affects the resolution of image exports.
If you want to change back to the default render setting of 720p, just remove -sfm_resolution 2160 -w 3840 -h 2160 from your launch options.
