When the Source Filmmaker exports your movie, its default is to render at 720p. This means that your movie will be 1280 pixels wide by 720 pixels high, which is an average resolution for most movies made with the SFM.
If you want to render at higher resolutions, you must set the appropriate command-line startup option before you launch the SFM.



Rendering
- Look up the width and height for your desired resolution, e.g. 1920 by 1080 for 1080p.
- Quit the Source Filmmaker if it's open.
- In Steam, right-click Source Filmmaker, click Properties, and where it says LAUNCH OPTIONS, add -sfm_resolution [height] -w [width] -h [height] to the end, replacing [width] and height with the width and height you looked up, respectively.
- 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 what you added from your launch options.
