Static Methods
applyTextAndEffects ({required String inputPath , required List <VideoEditorClip clips , required List <VideoTextOverlay textOverlays , required List <VideoEffectOverlay effectOverlays → Future <String
Burns clip effects, effect overlays and text into an existing video.
canvasFor ({required List <VideoEditorClip clips , required VideoAspectRatio aspectRatio , required int shortSide → Size
Canvas the project renders to for aspectRatio at shortSide pixels.
convertImageToVideo ({required File imageFile , required Duration duration → Future <File
disableHardwareEncoder ()
→ void
Stops using the hardware encoder for the rest of this session.
executePlan (RenderPlan plan , {RenderProgressCallback ?onProgress , RenderJob ?job → Future <void >
Runs plan with FFmpeg, reporting progress and honouring job.
generateProxyVideo (File inputVideo → Future <File
A small (480 px short side) copy of inputVideo for fast previews,
encoded with the hardware encoder when the device has one.
generateThumbnail (File videoFile , {Duration time = const Duration(seconds: 1) → Future <File ?
generateThumbnailStrip (File videoFile , {int count = 8 → Future <List <File
getVideoDuration (File file → Future <Duration
getVideoResolution (File file → Future <Size
hardwareEncoderAvailable ()
→ Future <bool
probe (File file → Future <MediaInfo
renderProject ({required List <VideoEditorClip clips , required List <VideoEditorAudioTrack audioTracks , required List <VideoTextOverlay textOverlays , required List <VideoEffectOverlay effectOverlays , required VideoAspectRatio aspectRatio , bool isPreview = false , ExportSettings settings = const ExportSettings() , RenderProgressCallback ?onProgress , RenderJob ?job → Future <String
Renders the whole project to an MP4 and returns its path.
runEncode ({required List <String argumentsFor (List <String encoderArgs required Size size , required Duration duration , RenderProgressCallback ?onProgress , int fps = 30 → Future <void >
Runs an FFmpeg job that encodes video at size: the phone's hardware
encoder first, x264 if that fails. argumentsFor gets the encoder
arguments to place before the output file. Throws RenderException .
videoCodecArgs ({required Size canvas , required int fps , required ExportQuality quality , required bool preview , bool hardware = false → List <String
Encoder arguments for canvas at fps: hardware H.264 on Android when
hardware is set, otherwise x264 (VideoToolbox on Apple platforms).
