How it works

Five steps.
You do two of them.

From hitting record to having a finished video you can post. Here’s the whole thing, including the parts that take a while.

1

You · takes as long as your video

Record or upload.

Record straight in the browser, or drop in something you shot on your phone. Vertical or horizontal — Kerliv keeps whichever you gave it.

You confirm you have the right to use the footage, and that’s the only thing standing between you and the upload button.

Worth doing before you record

  • Wear something that contrasts with your background. A dark shirt on a dark wall is the hardest case for background replacement.
  • Light your face from the front. Backlighting makes edges harder to separate cleanly.
  • Keep gestures relaxed. Hands moving fast close to the lens can blur enough that the cutout softens.

Kerliv · about a minute

It listens to what
you actually said.

Your audio gets transcribed, word by word with timings. Then that transcript is read for the beats worth illustrating — the number, the claim, the moment that needs a visual — and matched against the library.

Nothing about your delivery is judged. It’s reading what you said, not how you said it.

What comes out of this step

  • A timed transcript of your speech
  • B-roll cues at the moments that earn them, each with a matched visual
  • A handful of phrases worth putting on screen
  • A backdrop that suits the subject, and three music tracks that fit

You · as long as you want

Review what
it chose.

The editor opens as soon as the upload lands, and each panel fills in as its part finishes. Within about a minute you have everything except the finished video — and everything you have is editable.

Swap a backdrop or pin one as your permanent look. Delete a B-roll clip that doesn’t fit, or drag it a few seconds later. Reword a line of on-screen text and drag it anywhere on the frame. Play all three music tracks and pick one, or none.

Steps 3 and 4 happen at the same time

This is the part that’s different. You’re not waiting for the render to finish before you can work — the review happens while it runs. By the time the video is ready, your edit usually already is.

Kerliv · roughly 6× your video’s length

The render.

Separating you from your background happens frame by frame, on a GPU, and it’s genuinely slow. A two-minute recording takes around 12 minutes. A ten-minute one takes about an hour.

You don’t have to sit there. Close the tab, shut the laptop, come back tomorrow — it runs on our servers either way, and your review from step 3 is still waiting when you return.

Export and post.

Export bakes in your B-roll, your text and your music, and hands you a file. Download it and put it wherever you were going to put it.

Change your mind later and re-export as many times as you like — swapping visuals, text or music costs nothing and doesn’t use any more of your monthly minutes.

The honest numbers

How long it
actually takes.

Most tools in this category don’t publish this. These are measured, not estimated — and they’re the reason step 3 exists.

Your recordingEditable atFinished at
1 minute~1 min~6 min
2 minutes~1 min~12 min
5 minutes~1 min~30 min
10 minutes~1 min~1 hour

“Editable at” is when the transcript, B-roll, text, backdrop and music are all ready to review. “Finished at” is when the rendered video exists. Times vary with your footage and how busy things are.
