Auto Editor
Auto-editor is a command-line automated video editor that uses FFmpeg to remove silence and inactive footage from video files. It functions as a processing suite with specialized cut generators that identify segments to trim based on loudness thresholds, motion analysis, and speech-to-text transcription.
The tool distinguishes itself by offering a flexible post-production workflow, allowing users to export automated cut timelines as XML or JSON files for use in professional non-linear editing software. Beyond simple deletion, it can perform dynamic playback adjustments, such as increasing the speed of quiet segments instead of removing them entirely.
The project covers a broad range of media manipulation capabilities, including audio normalization, sibilance reduction, and visual effects like layer compositing, graphics overlays, and scale transformations. It also supports the ingestion of remote media via URLs and provides utilities to preview edit statistics without rendering the final video.
Features
- Automated Video Editors - Functions as a command-line automated video editor leveraging FFmpeg to remove inactive footage.
- Audio Transcriptions - Converts spoken audio from video files into text using speech-to-text models to drive editing decisions.
- Speech to Text Transcription - Converts spoken audio into text to determine which video segments to keep or remove.
- Still Footage Removal - Detects still footage through motion analysis to automatically trim non-active video segments.
- Clip Concatenations - Stitches together selected time ranges from a single source into a continuous output sequence.
- Clip Trimming - Adjusts start and end points of media segments to remove unwanted footage or alter playback speed.
- Linear Edit Timelines - Represents video edits as a sequential list of segments with associated start times and durations.
- Motion Vector Calculation - Detects still footage by measuring pixel-level changes between frames to identify sections with minimal movement.
- Transcript-Based Editing - Uses synchronized text transcriptions as an interface to determine which video segments to keep or remove.
- Segment Removal - Cuts video or audio sections based on loudness and motion analysis using configurable expressions and smoothing rules.
- Silence Detection - Identifies inactive audio segments by analyzing amplitude levels against user-defined decibel thresholds.
- FFmpeg Transcoders - Processes video and audio by generating complex filter graphs and command-line arguments for the FFmpeg engine.
- Video Editing - Removes silent or motionless sections from video files to create a concise final cut without manual trimming.
- Audio-Driven Cutting - Cuts out inactive audio segments based on a configurable loudness threshold to eliminate dead space.
- Inactive Media Removal - Jumpcut cuts out silent or motionless sections from files based on loudness thresholds and motion analysis.
- Still-Frame Cutting - Cuts out sections of a video where there is little to no motion to clean up recordings.
- NLE Sequence Exports - Translates internal timeline data into industry-standard XML formats for interchange with professional non-linear editors.
- Video Timeline Exports - Exports video project states and timelines as XML or sequence files for external professional refinement.
- Nonlinear Timeline Generation - Creates structured timeline files from media that support multiple overlapping audio and video layers.
- Level Normalization - Adjusts audio volume using peak amplitude scaling or perceived loudness analysis to ensure consistent levels.
- Transcription-Driven Slicing - Determines video cut points by matching timestamps from speech-to-text model outputs with the raw media timeline.
- Audio Volume Controls - Changes the loudness of audio sections using a multiplier or interpolates volume over time using a ramp.
- Clip Effects Pipelines - Modifies individual media segments using action strings to adjust properties like speed, volume, zoom, and color.
- Dynamic Zoom Transformations - Zooms the image in or out by a specified factor or animates the zoom level using a ramp.
- Edit Decision Overrides - Forces specific time ranges to be kept, sped up, or assigned custom actions regardless of automated analysis.
- Edit List Generation - Generates timestamp sequences as XML or JSON files to define cuts and joins for professional editing software.
- Silence-Based Speed Adjustment - Increases the playback speed of quiet segments instead of removing them to maintain a continuous timeline.
- Layered Compositing Stacks - Manages multiple overlapping video tracks by calculating z-index positioning and transparency for overlays.
- Playback Speed Controllers - Provides tools for adjusting the playback rate of media segments to maintain timeline continuity without deleting footage.
- Segment Action Overrides - Jumpcut overrides default processing by assigning specific actions to a defined start and end timestamp.
- Segment-Based Effect Groups - Modifies specific video segments by adjusting playback speed, volume, and zoom levels based on predefined groups.
- Trigger-Based Editing Actions - Assigns behaviors like speeding up or deleting segments based on custom-defined audio or motion triggers.
- Video Compositing - Stacks multiple video tracks from bottom-to-top to create overlays with custom positioning and transparency.
- Visual Overlays - Adds images or videos on top of existing footage with customizable positioning and animations.
- AI Video Post-Production Suites - Implements a post-production workflow combining AI transcription and automated editing to generate professional edit decision lists.
- Video Encoding Tools - Python tool to automatically remove silence and jump cuts.
