How to make a commentary videoSix steps, one project

  1. 1

    Know your point first

    Write down the one thing you want viewers to take away, then pick the moments of the clip that show it. A reaction can stay loose. A commentary needs a point.

  2. 2

    Record yourself, or type it

    Film your face cam with a webcam or phone while you watch. Clap once at the start so you can line your recording up with the clip later. No mic? Type the script under Audio, Voiceover.

  3. 3

    Start in the right shape

    New projects open at 1080 x 1920 for TikTok, Reels and Shorts. For YouTube, set 1920 x 1080 in the Canvas panel. Put the clip on one track and your face cam on the track above it; the top track draws on top.

  4. 4

    Place your face

    Select the face cam and type its X, Y, W and H. Turn off Keep aspect ratio to fit a square, then move Crop focus onto your face. Corner radius rounds it. Greenscreen, under Effects, drops a green backdrop.

  5. 5

    Cut to your points, keep your voice on top

    Press S to split the clip and delete what you don't talk about. Where you speak, lower the clip's Volume to about -14 to -18 dB. Turn off Enable audio where the clip should be silent.

  6. 6

    Caption it and export

    Open Captions and press Auto captions. Pick a preset and fix any word it got wrong, then export an MP4 at 1080p or 4K.

No mic? No camera?Three ways to voice it

Your own voice
Record it with any mic, even a phone in a quiet room, and upload it to the project.
Your recording, another voice
Voice change in the Audio tool re-voices a recording of up to five minutes. Your timing and emotion stay.
A typed script
Type it under Voiceover and pick a voice from the library, or clone your own voice from a sample and type with it.

Watch his left hand. The windmill builds all that speed, and one hand has to stop it. That's the freeze.

Read by library voices from the typed line. The same line plays over the breakdancer in the commentary at the top of the page.
