How to Edit Videos With AI: A Practical Workflow

Step 1: Upload and let it index

Drop your camera footage, screen recording or phone clips into Uploads. While you are still deciding what the video should be, the editor is already transcribing the speech and reading the footage, which is what makes later requests like 'cut everything before I introduce myself' resolve to a real timestamp instead of a guess. You can start editing as soon as the clip is on the timeline.

Step 2: Decide the structure before you decide the style

The most common way to waste time is to style a video that is still the wrong shape. Get the order and the length right first: which clips are in, in what order, and roughly how long the finished video should be. If you are not sure what is worth keeping, ask for the assessment rather than the edit — the editor can watch the footage and tell you where the strong moments are before it cuts anything.

Step 3: Tighten the pacing

This is the highest-value automated step on any spoken video. Cubix cuts pauses, breaths, filler words, stutters and immediately repeated phrases on word boundaries, and the whole pass is a single undo. Choose the mode by how the video should feel rather than by a number: gentle keeps thinking room, medium is the sensible default for most talking-head content, and aggressive gives you the tight jump-cut rhythm short-form expects.

Step 4: Frame it for where it is going, then caption

Set the project frame before you caption, because changing the aspect ratio afterwards moves everything on screen. A 16:9 project suits YouTube and embedded web video, 9:16 suits TikTok, Reels and Shorts, and 1:1 suits LinkedIn feeds. When you convert a widescreen recording into a vertical frame, Reframe crops it around the subject so the speaker stays in shot rather than drifting to the edge.

• Frame keeps the whole shot in an inset card — nothing is cropped away.
• Fill crops to cover the new frame, which is the right choice for a full-bleed vertical.
• Reframe follows the subject, which is what you want on a widescreen talking head going to 9:16.

Step 5: Look, motion and sound

Only now is it worth spending time on the finish. Grading, punch-in zooms, speed ramps, music and sound effects are all small requests once the cut is right, and they are all reversible independently. Restraint reads as production value: one deliberate look, a few zooms that land on real emphasis, and a music bed ducked under the voice will beat a pile of effects every time.

• A look: ask for a named grade (Golden Hour, Film Print, Kodak, Noir) or just ask for a cinematic finish and let Cubix apply its own graded pass.
• Motion: punch-in zooms on the lines that matter, a freeze frame to land a punchline.
• Sound: generated background music or a library track, ducked under speech so the voice stays clear.
• Cutaways: B-roll over the dialogue when you are describing something the viewer should see.

Step 6: Review, correct, export

Watch it once end to end before exporting. Corrections are conversational — you do not have to undo a good edit to fix one detail in it, and asking for the specific change keeps everything else intact. When it plays the way you want, export to MP4 at high quality; WebM and lower quality settings are there when you need a smaller file.
