If you’re new to Source Filmmaker (SFM) and feeling unsure about how to compile or export your project, you aren’t alone. That final step often stalls beginners, but getting the hang of it is essential for sharing your animation or poster with others. This guide lays out compiling in SFM compile for 2025 in straightforward, friendly terms—no jargon or unnecessary complications.
What Does “Compile” Mean in SFM?
In SFM, compiling means turning your project into a file others can view—such as an image or a video. If you’ve used other programs, this is similar to exporting or rendering. There are three main ways to export from SFM:
- Poster: A single image.
- Movie file: A video, usually in .AVI format.
- Image sequence: A batch of still frames that play like a video.
You’ll choose the export type based on your goal: posters are excellent for thumbnails or artwork, image sequences are preferred for top-quality, and AVI video is fast for sharing clips.
Before You Compile: Quick Checklist
Take a minute to double-check these essentials before hitting compile:
- Finalize Your Animation: Make sure movements, lighting, props, and camera work are all completed.
- Lock Your Camera: Right-click your shot in the timeline and choose “Lock Camera to Shot” so the render matches your editor view.
- Set Your Frame Range: Define correct start and end frames to avoid exporting blank space.
- Save Your Project: Always use “Save As” and add a version number (for example, scene_v2.dmx). This can save your work if you need to go back.
SFM Compile Options (And When to Use Each)
Here’s a breakdown of the main ways to compile in SFM, so you can pick the method that suits your needs:
1. Poster (Still Image)
- Best for: Screenshots, wallpapers, thumbnails, sharing character poses.
- Format: PNG is recommended because it’s clear and supports transparency.
- How to export: Go to File > Export > Poster, select your camera, and save.
2. Movie File (.AVI)
- Best for: Quick videos or short clips.
- Advantages: Fast, simple, and requires no extra software.
- Drawbacks: File sizes can be very large, and .AVI may not play on all devices.
- Tip: Choose “Uncompressed” or “Raw” for the highest quality—convert it later if needed.
3. Image Sequence (Highest Quality)
- Best for: When you want top visual quality and plan to edit later.
- How it works: SFM saves each frame as an image (TGA or PNG). You’ll need another program to turn these into a video.
- Perk: If there’s an issue, you can re-render just the problem frames instead of the whole sequence.

How to Compile in SFM (Step-by-Step)
To Compile a Movie File (AVI)
- Go to File > Export > Movie
- Choose your shot, resolution, and format
- Set your frame range
- Select “Uncompressed” or “Raw AVI”
- Click “Export Movie”
Note: SFM does not export directly to MP4. You’ll need to convert the AVI file later.
To Compile a Poster
- Pause the timeline on your chosen frame
- Go to File > Export > Poster
- Select your camera and PNG format
- Save the file
To Compile an Image Sequence
- Go to File > Export > Image Sequence
- Choose the frame range and the file format (PNG or TGA)
- Set your save location and export
- Use separate software to convert the sequence into a video.
How to Turn Image Sequences Into Videos
Option 1: FFmpeg (Free and Fast)
Use a command like:
ffmpeg -framerate 24 -i frame%04d.png -c:v libx264 -pix_fmt yuv420p output.mp4
This assembles your image sequence into a smooth MP4 video.
Option 2: Video Editors (Premiere, DaVinci Resolve, etc.)
- Import the image sequence as a clip
- Add music, cuts, and effects
- Export as MP4 or MOV
Great for further editing before publishing.
Common Problems and Fixes
| Problem | Solution |
| Black screen | Lock camera to shot and check the camera track |
| Missing frames | Verify your frame range and animation keys |
| No audio | Export sound separately and merge it in an editor |
| Low resolution | Increase render settings or use launch options |
| AVI file won’t open | Convert with VLC, HandBrake, or FFmpeg |
Pro Tips for Smooth Compiling
- Test render a few seconds of your animation before exporting the whole thing.
- Close unnecessary programs to free up resources.
- Save often to prevent data loss.
- Consider running large renders overnight.
After Compiling: What’s Next?
Once you’re done compiling your animation, here’s what you can do:
- Polish in an Editor: Trim away extra frames, add music or effects, and include titles or transitions.
- Upload:
- YouTube: MP4, 1080p or higher recommended.
- TikTok: Crop vertically in CapCut or similar.
- Discord: If needed, compress your file with HandBrake to keep it under 25 MB.
