BCut documentation

Getting started

What BCut does

BCut analyzes video and audio on your computer, finds the parts that slow an edit down, and prepares a clean cut for export.

Import your files. Let BCut do the work. Click Export. That is the intended workflow. The defaults are designed to be reliable enough that most projects need no settings changes or manual cleanup, letting you use the result immediately and keep moving.

BCut detects silent pauses, filler words, and repeated takes. Review is always available when you want more control. Every suggested cut remains visible and reversible in the transcript and waveform, and your original source file is never changed.

From raw clip to first cut

System requirements

Faster processors reduce transcription and export time. The Small and Medium models also benefit from more memory, especially with long recordings.

Workspace

Know your way around

The BCut window is organized around one review workflow. The video stays on the left, the transcript stays on the right, and the shared waveform runs below them.

Import media

Drag files anywhere over the empty media area, or click the area to open the file picker. When a project is already open, dropping new files asks before replacing the current work.

Selecting one file starts a standard project. Selecting two or more files starts a multicam project and syncs the clips by audio.

How suggested cuts work

BCut extracts audio, creates a transcript, and combines speech timing with audio analysis. Suggested cuts are selected by default, but they remain editable throughout review.

Silences and pauses

Quiet regions longer than the configured minimum are marked as pauses. Auto Threshold analyzes the clip and chooses a practical level. Manual threshold control is available when the recording has steady background noise or very quiet speech.

Filler words

Words such as “um,” “uh,” and language-specific equivalents are matched against the active filler list. Context-dependent words are treated more carefully so normal uses are less likely to be cut.

Repeated takes

BCut compares neighboring transcript phrases to identify false starts and repeated attempts. Review these suggestions closely when the speaker intentionally repeats a phrase for emphasis.

Joined cuts

When a filler sits very close to a silence, Join nearby cuts combines them into one clean edit. This avoids leaving tiny fragments between adjacent cuts.

Review every edit

Use playback, the transcript, and the waveform together. The currently playing transcript segment follows the playhead, and clicking text jumps playback to that point.

Filter the transcript

The All, Pauses, Repeats, and Fillers tabs let you isolate one category. Select all toggles every visible suggestion in the active category.

Keep or remove a segment

Click a highlighted pause, filler, or repeat to toggle its cut state. Selected cuts use their category color and a strike-through treatment. Click again to keep that part of the recording.

Read the result before export

The status bar shows how many cuts are selected and the estimated cleaned duration. Use this as a quick check for unexpectedly aggressive settings before exporting.

Customize filler detection

Open the Fillers panel from the transcript toolbar to inspect the list for the detected language.

Multi-word entries are treated as phrases. Entries shown as context-dependent are only cut when their timing or transcription confidence suggests that they are fillers.

Multiple sources

Sync a multicam project

Select multiple video and audio files in a single import. BCut compares their audio waveforms, places them on a shared timeline, then runs detection on the chosen audio source.

Default sources

The first video becomes the default preview angle. If the selection contains a standalone audio file, the first audio-only clip becomes the default transcription source. Otherwise, BCut uses the primary video.

Switch video or audio

Use the selectors below the preview to change the visible video angle or the audio source. Changing the video is immediate. Changing the audio source reruns transcription and cut detection because the transcript belongs to that recording.

Weak audio matches

If the match confidence is low, BCut names the affected clips in a warning. Exported angles may be misaligned, so verify the sync in your editor. Clips need overlapping, audible content for reliable automatic sync.

Export your cut

Open Export in the header after processing completes. The menu includes finished video and editable timeline formats. Watermarking is based on your plan, not the selected video resolution: every Free video export includes a BCut watermark, while every Pro video export is watermark-free.

Timeline exports preserve cut decisions as edit points and reference the source files. Keep the original media in place until the project has been imported and relinked successfully.

Configuration

Tune detection

Open the gear button in the header. Changes are staged until you click Save. If media is already loaded, changing the language or model starts a fresh transcription.

Setting	Default	What it controls
Auto Threshold	On	Analyzes the clip and chooses a silence level automatically.
Threshold	0.012	How quiet audio must be to count as silence. Lower values cut only very quiet gaps.
Min silence	0.5 s	The shortest pause that BCut will suggest as a cut.
Silence margin	0.15 s	Audio kept around a silence cut to protect the edges of speech.
Join nearby cuts	150 ms	Combines adjacent silence and filler cuts separated by a short gap.
Filler padding	0.05 s	Extra audio included around a filler word cut.

Use Reset to return detection controls and language selection to their defaults. Theme, model management, updates, license state, and telemetry permission also live in Settings.

Choose a transcription model

Models are downloaded once and stored on your computer. You can cancel an active download or delete a model you no longer need from Settings.

Language selection

Auto-detect works well when a clip has a clear primary language. Selecting a language directly can reduce uncertainty and improve processing consistency. BCut supports 96+ transcription languages. English, Vietnamese, and Japanese include enhanced curated filler lists, and every language can use a custom list.

Plans and license activation

The Free plan includes detection, review, and 720p or 480p video exports with a BCut watermark. BCut Pro removes the watermark from every video resolution and unlocks 1080p, FCPXML, and Premiere XML exports.

Activate a key

Open Settings, choose Upgrade, and enter the license key from your purchase. A checkout link can also return directly to BCut and activate the key through the app.

Move a license

Open Settings on the current computer and choose Deactivate. You can then activate the key on another machine. BCut periodically verifies subscription licenses when internet access is available and keeps a grace period for offline work.

Your media stays local

Transcription, detection, review, and export run on your computer. BCut does not upload your video, audio, transcript, or file contents for processing.

On first launch, the app asks whether you want to send anonymous usage and crash reports through PostHog and Sentry. This is optional. If you decline, telemetry remains off. You can change the choice later in Settings.

Keyboard shortcuts

Shortcuts work while focus is outside a text field, selector, or other form control.
