A subtitle-driven, cross-platform desktop video editing tool. Say goodbye to timeline dragging — select, edit, and export videos using text instead.

Introduction

The traditional video editing paradigm has dominated the industry for decades: import footage, drag it onto a timeline, make precise cuts, add transitions, and render the final output. This workflow is powerful and comprehensive, but for many content creators, it may be unnecessarily complex.

If you're a podcast editor who needs to trim an episode based on conversation content; if you're editing an interview video and want to quickly remove filler words like "um" and "uh" along with repetitive segments; or if you have a long video with subtitles and need to extract highlights based on the text — what you really need is not a full non-linear editing system, but a more intuitive way to select segments.

X-Cut was built for exactly these needs. Its core philosophy can be summed up in five words: Edit videos with subtitles.

What is X-Cut

X-Cut is a cross-platform desktop application built with Electron, supporting both macOS and Windows. It uses subtitles as the core driving element for video editing, allowing users to complete video segment selection, editing, and exporting by reading and manipulating subtitle text.

Unlike traditional NLE software such as Premiere Pro, Final Cut Pro, or DaVinci Resolve, X-Cut has no complex timeline panels, no multi-track editing, and no transitions or effects. Instead, it turns subtitles into an interactive video segment selection interface — when you see a subtitle, you see the corresponding time range of the video; when you select a subtitle, you've selected a segment of video.

Key Features

Multi-Format Media Import

X-Cut supports importing a wide range of media file formats:

Video: MP4, WebM, MOV, OGV, FLV, and more
Audio: MP3, WAV, M4A, AAC, FLAC, and more
Images: JPG, PNG, GIF, WebP, BMP, and more

Upon import, the application automatically retrieves media metadata (resolution, duration, frame rate) for subsequent editing and exporting.

Subtitle-Driven Editing

This is X-Cut's core feature. After importing media, you can add subtitles in multiple ways:

Import External Subtitles: Supports mainstream subtitle formats including SRT, VTT, ASS/SSA, and SUB
Generate Blank Subtitles: Automatically creates segmented blank subtitle entries at fixed intervals (25 seconds)
Whisper AI Speech Recognition: Automatically generates timestamped subtitles for videos using an embedded Python environment and the OpenAI Whisper model
Smart Scene Detection: Automatically detects scene change points in videos using the scenedetect library and generates corresponding subtitle segments

Once imported, the editor displays subtitles in a hierarchical structure: Media → Subtitles → Segments → Entries. Each subtitle entry corresponds to a time range in the video — hovering over it provides real-time preview of the corresponding video frame and audio.

Quick Selection Operations

X-Cut provides a set of efficient selection operations within the subtitle editor:

Action	Description
Mouse Hover	Real-time preview of the video frame and audio corresponding to the subtitle
Click	Select or deselect a subtitle entry
Click & Drag	Batch-select subtitles as you drag across them
Shift + Drag	Batch-deselect subtitles as you drag across them
B Key	Split a subtitle into two entries at the cursor position
D Key	Merge two subtitle entries on either side of a divider
Space Bar	Play/pause the current video
P Key	Capture the current frame to the desktop

Selected subtitles are highlighted in orange for clear visual feedback.

Timeline Management

X-Cut supports creating multiple timelines, each independently recording selected subtitle entries. You can organize different editing plans across timelines without interference. Timelines support drag-and-drop reordering, renaming, and deletion.

Real-Time Preview & Playback

The right-side preview panel provides full media preview capabilities:

Native playback of video, audio, and images
Audio waveform visualization
Time indicator showing the current preview position
Timeline playback mode: plays all selected segments in sequence, with pause and seek support

The bottom timeline preview bar displays all selected segments as color blocks showing their proportions and text content. Clicking any block jumps directly to the corresponding segment.

Video Export

After selecting segments, X-Cut uses FFmpeg for high-quality export:

Segment-by-segment encoding followed by merging, ensuring precise time control
Video: H.264 encoding, CRF 18, high-quality output
Images: Automatically converted to video segments with silent audio
Audio: Automatically combined with a video background and converted to standard video format
Automatic handling of segments with different resolutions, with unified letterboxing
Simultaneous export of VTT subtitle files
Real-time export progress display

FCPXMLD Export (Pro Version)

Pro users can export editing results in FCPXMLD format for direct import into Final Cut Pro for further editing. The exported file includes correct media asset references, frame-aligned timecodes, and subtitle text embedded as Marker annotations.

Technical Implementation

X-Cut's tech stack balances development efficiency and user experience:

Layer	Technology
Desktop Framework	Electron 40.6
Build Tool	Electron Forge + Vite
Frontend Framework	React 19 + TypeScript
UI Components	Ant Design 6 (localized)
Drag & Drop	@dnd-kit
Video Processing	fluent-ffmpeg
AI Speech Recognition	OpenAI Whisper (embedded Python 3.12)
Scene Detection	PySceneDetect (embedded Python 3.12)

Notably, X-Cut embeds a complete Python 3.12 runtime environment. On first launch, the application automatically extracts the Python runtime and FFmpeg tools to the user's directory and installs the Whisper and scenedetect dependencies via pip. The entire process is fully transparent to the user — no manual environment configuration is required.

Three-Panel Layout

The project editing interface uses a classic three-panel layout:

Left Panel (Media Panel): Manages imported media files and subtitles. Both media and subtitle files support drag-and-drop reordering for flexible content arrangement, along with right-click context menu operations.
Center Panel (Editor): Displays the subtitle list on the left and the video preview on the right.
Right Panel (Timeline Panel): Manages the timeline list and handles video export.

All three panels can be resized by dragging the divider lines, and each can be toggled between hidden and visible.

Use Cases

X-Cut is particularly well-suited for the following scenarios:

Podcast/Interview Editing: Import subtitles generated from audio recordings and quickly locate and select highlight segments by reading the conversation text.
Tutorial/Course Editing: Quickly remove repetitive explanations, verbal mistakes, and invalid segments based on subtitle content.
Meeting Recording Editing: Use AI-generated subtitles to rapidly filter and select meaningful discussion content.
Short-Form Content Curation: Perform initial screening on long videos and export highlight clips for secondary creative work.
Subtitle-Driven Workflows: Any scenario where video editing decisions are guided by textual content.
