Natural language editing

Describe the outcome. Keep the editable timeline.

Traditional editing requires hunting through timelines, splitting clips, ripple-deleting gaps, and manually keyframing zooms. Editing by chat lets you state your creative goal in plain English while keeping every cut fully visible and adjustable.

01

Give clear direction

Describe what to cut, what to keep, and how to style captions. Name the lines and details that should remain, then compare them with the result.

02

Inspect the timeline draft

Cubix plans supported editing operations and applies them to your footage. Cuts, caption tracks, and framing layers appear directly on the timeline.

03

Refine with precision

Review playback with sound. If a cut feels slightly abrupt, submit a focused conversational adjustment or drag the trim handles manually.

Recording and finished export

Compare the brief with the actual result.

This travel-vlog example uses a supplied recording and its natural-cleanup export. Read the brief, compare the files and listen to the retained passages.

Edit A

Request a shorter edit with natural pacing, readable captions and the original aspect ratio.

Supplied editing brief

“Clean up this recording. Shorten long pauses and remove false starts. Keep the full explanation and natural pacing. Add readable captions and keep the original aspect ratio.”

What to compare

  • 46.68-second export, about 27% shorter than the supplied source.
  • Landscape travel footage with captions visible in the picture.
  • Compare the retained passages and listen around cuts before choosing this pacing.

The source is 64.04 seconds and the cleanup export is 46.68 seconds, about 27% shorter. The landscape result includes captions. Play both versions to compare the pacing, captions and retained passages.

Supported editing jobs

Ask for the exact change your video needs.

Rather than giving vague commands like 'make this viral', direct the agent toward concrete, supported tasks. These example requests show how to specify the goal while protecting essential content.

Tighten the opening hook

A spoken recording often begins with hesitant setup, throat clears, or false starts. Ask Cubix to tighten the first twenty seconds while preserving the core premise.

“Tighten the opening of this recording. Remove unnecessary waiting and repeated setup. Keep complete sentences and the qualification in my explanation. Add readable captions.”
Explore the editing agent

Trim dead air and conversational gaps

Shorten pauses between sentences without removing deliberate breathing room or clipping trailing consonants.

“Shorten conversational gaps longer than 0.8 seconds. Preserve deliberate rhetorical pauses after questions, keep all word endings, and maintain original framing.”
Explore silence trimming

Add and position readable captions

Generate subtitles, then review their wording, timing and placement. Request margins that suit your destination platform.

“Add clean, readable captions. Keep text to a single line with at most 4 words per segment, positioned safely above bottom social media interface buttons.”
Explore captions

Reframe for vertical platforms

Convert a landscape recording into a vertical 9:16 deliverable. Keep the speaker comfortably framed while leaving room for captions.

“Reframe this clip for a vertical 9:16 aspect ratio. Keep the speaker’s face centered in the upper half of the frame and leave space below for captions.”
Explore reframing

Complete review control

The conversation gives the brief. The timeline holds the work.

Chat instructions do not lock your video into a black box. Once Cubix applies your request, every cut, zoom layer, and subtitle block sits on a visible multi-track timeline.

  • Inspect cut junctions: verify that initial and trailing consonants remain intact.
  • Caption text and styling: correct proper nouns and adjust font sizing or colors.
  • Crop and headroom: confirm dynamic reframing never cuts off eyes or illustrative gestures.
  • Full export review: open the downloaded MP4 file and listen with headphones before publishing.

Step-by-step workflow

From raw recording to polished export in four steps.

  1. 01

    Upload your footage

    Bring your recorded MP4, MOV, or screen capture into the Cubix desktop editor. Keep the original recording available for comparison.

  2. 02

    Type your editing brief

    Open Ask Cubix and type what you want changed. Name the goal, section boundaries, pacing preference, and any constraints you need preserved.

  3. 03

    Inspect the draft timeline

    Play the resulting timeline with sound. Check cuts at word boundaries, inspect caption accuracy, and review visual framing across every edit.

  4. 04

    Refine and export

    Submit a conversational follow-up to tweak a specific passage or adjust timeline handles directly. Once satisfied, export your high-resolution video.

Prompting best practices

How to write a clear editing brief.

The most successful editing briefs establish four clear boundaries: the primary goal, the scope of the footage to touch, the constraints that must be preserved, and the desired visual finish.

Goal
State the intended viewer outcome: a clean explainer, a teaser clip, or a punchy social reel.
Scope
Identify whether to edit the entire recording, tighten the opening, or extract a specific segment.
Constraints
Specify what must NOT be cut: key qualifications, technical demonstrations, or specific quotes.
Finish
State your preferences for pacing thresholds, caption font style, and canvas aspect ratio.

Starter brief · adapt for your recording

“Tighten the opening of this recording. Remove unnecessary waiting and repeated setup. Keep complete sentences and the qualification in my explanation. Add readable captions and keep the current aspect ratio.”

Click to copy. Paste into Ask Cubix after uploading your video, then customize the constraints to match your recording.

Iterative refinement

Follow up conversationally or adjust manually.

Submit a targeted conversational revision

Point directly to the section that needs adjustment. A targeted revision like extending a specific breath pause or re-centering framing is much more reliable than asking the agent to make the whole video 'faster'.

“The cut after the product demonstration feels slightly rushed. Restore 400 milliseconds of breathing room before step three, and keep existing captions intact.”

Fine-tune with direct timeline handles

When you know the exact frame you want to adjust, use standard timeline controls. Drag clip boundaries, edit subtitle wording in the text box, or reposition text blocks visually on the video preview canvas.

  • Scrub across cut junctions to ensure no trailing consonants were clipped.
  • Verify that retained sentences preserve the speaker’s original meaning.
  • Check caption placement against platform safe areas.
  • Watch the full rendered export with headphones before sharing.

Choosing your workflow

When to use chat instructions versus manual tools.

Different editing tasks benefit from different workflows. Understand when conversational briefs save time and when manual adjustments are the better choice.

Chat-to-edit with Ask Cubix

Describe broad creative outcomes: silence tightening, multi-track coordination, and caption styling across your footage.

Best for: Initial rough cuts, multi-step pacing cleanup, and format reframing.

Direct timeline trimming

Drag clip handles, split at the playhead, and make sub-second timing tweaks directly on the visual timeline.

Best for: Precise syllable micro-edits, exact cut boundaries, and creative pacing nuances.

Focused single-action tools

Use dedicated workflows for specific tasks such as silence removal, caption generation, or video cropping.

Best for: Single-job passes where only one parameter needs adjustment.

Planning your edit

Start with good audio. Use a desktop browser.

Start with a recording you can hear and inspect clearly. Review the transcript, cut boundaries and framing before accepting the edit.

  • Use clear spoken audio where possible, and listen around each proposed cut.
  • Use a modern desktop or laptop browser for the full timeline editor.
  • Review current plan terms for export resolutions, storage, and processing credits.

Frequently asked questions about editing by chat.

Editing by chat means directing changes to your existing recorded video using natural language instructions instead of manually splicing clips tool by tool. In Cubix, your request is interpreted into timeline actions—such as trimming pauses, adjusting framing, and adding captions—leaving the result fully editable on a multi-track timeline.

Yes. Cubix edits footage that you record and bring to the editor. It does not generate synthetic AI avatars, fictional talking heads, or video from text prompts alone. You provide the original speech, visual presentation, and story; chat instructions shape and polish that footage.

Because the draft remains on an editable timeline, you retain complete control. You can submit a targeted conversational follow-up (e.g., restoring a specific pause or adjusting caption styling), use the visual timeline trim handles to make precise manual edits, or use standard undo controls.

Yes. You can give a multi-part editing brief, such as tightening conversational pauses, keeping a technical explanation complete, and adding clean subtitles. For best results, state what should change, what must be preserved, and the required visual framing.

Transcript editors let you delete or reorder words by highlighting text in a transcript. Chat editing in Cubix works at the project level: you describe higher-level outcomes (pacing, silence thresholds, framing changes, and caption styling) and the system coordinates multi-track timeline operations across video, audio, and text.

A chat instruction is a request to an editing agent, not an infallible program. Always review the resulting timeline draft with sound. Trailing consonants, breath pauses, and visual continuity should be checked before final export.

The full Cubix editing experience runs in modern desktop and laptop web browsers. Check our pricing page for current details on export resolutions, project storage, and subscription terms. Always download and review your rendered video before publishing.
