Editing with Cubix3 min readLast updated September 2026

Cut, trim and reorder clips

Slice video segments by time or text, rearrange clip order, and remove unwanted footage instantly.

What this does

Gives you both prompt-driven cutting — 'cut the section where I talk about pricing' — and the ordinary timeline tools for splitting, trimming and rearranging clips by hand.

Note

Cubix uses non-destructive editing so your original media files are never overwritten.

How to do it

Follow these step-by-step instructions in Cubix.

1

Identify what you want changed

Point at it by timestamp, by what you said there, or by topic. Quoting a distinctive phrase is usually the most reliable, and unlike a timestamp it keeps working after you have re-cut the video and everything has moved.

2

Ask, or do it on the timeline

Describe the change and Cubix applies it, or drag the clip edges yourself. Both write to the same timeline, so you can mix them freely within a single edit.

Example Prompt for Cubix AI Agent
"Move the introduction to the beginning and trim the ending after 02:45."
3

Split a clip where you need a break

Splitting divides a clip at a point without duplicating anything, leaving both halves independently editable. Any speed, zoom or colour work already applied carries across to both. If you want a transition between the two new pieces, add it as a separate step after the split.

4

Adjust clips already on the timeline in place

To shorten, extend or slide something that is already placed, trim it rather than deleting and re-adding it. Pulling the left edge cuts the head, pulling the right edge cuts the tail, and moving the clip slides it without changing its content. This works on video, audio, images and text.

Example Prompt for Cubix AI Agent
"Start the music at 5 seconds and trim the intro clip a bit shorter."
5

Decide whether the gap should close

When you shorten one clip in a chain of cuts, rippling pulls everything after it back so the sequence stays butted together. For a standalone item — a music bed, a sound effect, an overlay — you usually want the opposite, with the clip simply starting where you said and nothing else moving.

Pro Tips for Best Results

  • Trimming keeps a clip's identity along with any effects, transitions and curves already on it — deleting and re-adding loses all of that.
  • Extending a clip past the end of its source is capped at what the file actually holds, and Cubix tells you where it landed rather than failing silently.
  • Get the order and the length right before you style anything. Structural changes shift everything after them, so captions and effects applied early have to be redone.
  • Reordering is allowed and often improves a video more than trimming does — the order you recorded in is rarely the order a viewer needs.
  • Markers let you pin a moment, leave a note or set a chapter cue while you watch, which is far easier than trying to remember timestamps for a later pass.
  • Smooth Cut, in the Audio panel, lets either clip's sound continue across a join — the classic fix for a dialogue cut that looks fine and sounds abrupt.

Because editing is non-destructive, none of this touches your uploaded files. You can cut a video down to thirty seconds and still recover the full original at any point.

Frequently Asked Questions

Common questions around this editing workflow.

Describe it by what was said — 'cut from where I say let me show you to the end of that tangent'. Quoted speech resolves against a word-level transcript, and unlike a timestamp it still works after the video has been re-cut.
