Rendering at 1080p
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 your movie to have a higher resolution, you can instead render at 1080p, which means a movie that is 1920 pixels wide by 1080 pixels high, also known as Full HD resolution.
If you want to render at 1080p, you must set the appropriate command-line startup option before you launch the SFM.
Note:Rendering at 1080p will take longer than rendering at 720p, especially with older/lower-end hardware.To render at 1080p:
- 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 1080 -w 1920 -h 1080to 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.
Bug:SFM will crash if you attempt to export as an image after changing the export resolution without first saving and reloading the session. [todo tested in?]If you want to change back to the default render setting of 720p, just remove -sfm_resolution 1080 -w 1920 -h 1080 from your launch options.
Tip:Having the SFM resolution set to 1080p may severely degrade viewport performance. For this reason, you might want to only switch to it when you are ready to perform your final movie layoff.Bug:SFM will crash if attempting to load a session with the export resolution set higher than the current launch option. [todo tested in?]Tip:If working at higher resolution, mark the file name appropriately to avoid confusion with the above issue.
