Exporting
Save an Astrofox composition as a still image or encoded video.
Astrofox exports the canvas at the resolution chosen in Project settings. The editor's stage zoom and panel layout do not affect the result.
Save an image#
Move playback to the frame you want, then select Save image in the action rail. Astrofox renders the stage and asks where to save the still image, using the best file-save flow available in your browser or desktop environment.
Save a video#
Select Save video in the action rail. The export dialog lets you:
- Choose or confirm the audio source
- Choose a save location when the platform supports it
- Set start and end times with fields, a waveform, or range handles
- Include or omit audio in the final file
- Select 30 or 60 frames per second
- Choose Low, Medium, or High quality
- On desktop, select x264, x265, NVEnc, or WebM encoding
Select an audio file at least five seconds long. This source defines the available export timeline even if the project was using live input.
Set a start time and an end time at least five seconds later. Use the highlighted waveform segment to verify the selection.
Start with Medium at 30 fps. Use 60 fps for fast motion or smoother social clips, and High quality for a final master when render time is less important.
Choose Save video. Astrofox renders the selected range. The Stop button cancels an active export.
Browser and desktop export#
| Platform | Export path | Typical output |
|---|---|---|
| Web | Browser MediaRecorder support | WebM, or MP4 where supported by the browser |
| Desktop with ffmpeg | Offline frame render followed by ffmpeg encoding | MP4 with H.264/AAC by default; other desktop encoders are selectable |
| Desktop without ffmpeg | Browser-compatible fallback | The format supported by the embedded browser |
Desktop offline rendering uses fixed frame timing, so animation and audio analysis remain deterministic. Plugin animation must use Astrofox's provided frame time for the same reason.
Choose an encoder#
- x264 is the safest general-purpose MP4 choice.
- x265 creates HEVC video and may be smaller, but playback support is less universal.
- NVEnc uses supported NVIDIA hardware for faster H.264 encoding.
- WebM is useful for web delivery and workflows that prefer the open WebM container.
A higher frame rate, resolution, and quality all increase render time and file size. Test a short segment before committing to a long final export.
