50 AI Video Editing Prompts That Actually Work
In an agentic editor, the prompt is the edit: you type what you want, the AI performs it on your footage, and you review the result. These 50 prompts are grouped by job — cleanup, captions, audio, motion, text & look, framing, and generation — and every single one maps to a real, shipped capability in Valmera's AI video editor. No aspirational examples: copy any prompt, paste it into the chat, and it works.

Three things to know before you start. First, prompts are plain English, not syntax — the agent has already analyzed your upload (a word-level transcript, shot boundaries, silences, and what's on screen; longer videos take longer, with visible progress), so it understands references to content, moments, and words, not just timestamps. Second, you can stack jobs: one message can request cuts, captions, music, and a reframe together, and you get one updated video per turn to review. Third, prompts that mention your own assets — a logo, a song, photos — assume you've added those files to the project first, either by uploading them or by pasting a link in chat.
Every reply is backed by Valmera's honesty layer: the agent's message is verified against the edits it actually performed, so a prompt is never "confirmed" without being done. More on that in Can AI Edit Videos?
Cleanup Prompts (1–8)
The highest-value minutes you'll ever save. Cuts snap to word boundaries, so removals never clip a syllable — and anything the agent cuts can be restored.
“Cut out all the silences and dead air, but keep the pacing natural.”
“Remove every um, uh, er, and hmm.”
“Treat ‘like’, ‘you know’, and ‘basically’ as filler words too, and cut them.”
You can extend the filler list with any words you overuse.
“I recorded multiple takes of some lines — detect the repeats and keep the best take of each.”
“Cut everything from 2:10 to 2:48.”
“Remove the part where I talk about the old pricing.”
The agent works from a word-level transcript, so you can name content instead of timestamps.
“That cut at 4:05 took out too much — restore it.”
“Trim the first 12 seconds and everything after my final sentence.”
Caption Prompts (9–16)
Captions are word-accurate, styled by request, and burned into the video. Presets include podcast, beast, karaoke, and elegant, with 12 bundled fonts and 9 entrance animations.
“Add karaoke captions — three words per line, with a yellow highlight on the word being spoken.”
“Caption the whole video in the podcast preset.”
“Make the captions bigger and move them to the middle of the frame.”
“Use the beast caption style and make the strongest words pop.”
“Switch the caption font to Bebas Neue and give each line a slide-up entrance.”
“Keep captions to four words max per line.”
Anything from 1 to 16 words per caption works.
“Every time I say ‘free’, hit that word with an accent color.”
“Elegant captions at the bottom, small, white.”
Audio Prompts (17–24)
There's a 24-track royalty-free music library across 8 moods, an 18-sound effects pack, and a mix engine that ducks music under speech with smooth sidechain compression.
“Add an upbeat track from the music library and duck it under my voice.”
“Loop the music to the end and fade it out over the last shot.”
“Analyze the song and tell me where the drop hits.”
“Make the cuts in the montage land on the beat.”
Beat-synced cuts — the agent declines honestly if the track has no reliable tempo.
“Do a sound-design pass — whooshes on the cuts, an impact on the strongest word, a riser into the peak.”
“Add a boom right when the title appears.”
“Mute my original audio and keep only the music.”
“Master the audio to standard loudness so it holds up on phone speakers.”
Masters to −14 LUFS / −1.5 dBTP — the loudness targets platforms expect.
Motion Prompts (25–32)
Speed works from 0.25x to 4x on any range with voices keeping natural pitch — though below about 0.6x, slow motion duplicates frames and visibly steps. Transitions come in 7 styles, applied as one global style at every cut.
“Slow the shot at 1:24 to half speed.”
“Speed the screen-recording section up to 2x.”
“Add a zoom punch transition at every cut.”
“Actually — switch the transitions to glitch.”
The other styles: dip to black, dip to white, whip left, whip right, flash.
“When I say ‘this is the one’, punch in on the bottle.”
Zooms are aimable at any point of the frame, up to 2.5x.
“Add automatic punch-ins on my most emphasized words.”
“End on a slow pull-out from the final shot.”
“Put my logo in the top-right corner and let it drift slowly across the intro.”
Text & Look Prompts (33–40)
Seven on-screen text templates (title, subtitle, lower third, callout, big number, quote, chapter), 6 grade presets plus custom grading, 8 stylize effects, and one-request looks that set the whole aesthetic at once.
“Make the whole thing feel cinematic — grade, captions, transitions, all of it.”
The looks: hype, clean, cinematic, luxury, meme. Every piece stays adjustable afterward.
“Apply the vintage grade.”
“Warm it up and add a little contrast, but don’t oversaturate.”
“Add film grain and a light vignette from 3:00 to 3:20 for the flashback.”
“Give the drop at 0:58 a quick camera shake.”
“Open with a title that says ‘THREE MISTAKES’ — big, white, pop entrance.”
“Add a lower third with my name and ‘Product Designer’ the first time I appear.”
“Show a big number ‘47%’ on screen when I mention the growth stat.”
Framing Prompts (41–45)
Reframe between 16:9, 9:16, 1:1, and 4:5 by crop, pad, or blurred pad — never upscaled. Censoring covers any region and follows through cuts and reframes (it doesn't chase a moving subject).
“Reframe this to 9:16 for Reels and Shorts.”
“Make it 1:1 with blurred padding instead of cropping.”
“Blur the license plate at 0:42.”
“Pixelate the email address in the top-right of the screen recording.”
“Black out the bottom third of the frame from 5:10 to 5:30.”
Generate & Import Prompts (46–50)
The agent can generate media into the edit — images as full-frame stills with Ken Burns motion, described sound effects, short AI video clips — or pull media in from a pasted link. Generations charge credits by their actual cost.
“Generate an image of a minimalist desk setup at golden hour and open the video with it.”
“Generate a deep cinematic boom and drop it on the title reveal.”
“Generate a 5-second clip of ocean waves at sunset and insert it before the outro.”
“Pull the song from this link and lay it under the whole video.”
Paste the link in chat — works for direct files and major video/audio pages.
“Start from these five photos — make a 4:5 slideshow with Ken Burns motion and an inspiring track.”
Canvas projects need no video at all: images, clips, and music become the timeline.

The pattern behind every prompt above: name the target (a time range, a spoken phrase, an object on screen, or "the whole video"), the action (cut, caption, duck, punch in, grade), and any style constraints (a preset name, a font, a color, a size). "Add captions" works; "karaoke captions, three words per line, yellow highlight" gets you the result you pictured on the first try. When you don't know the vocabulary, describe the feeling — "make it feel like a luxury ad" — and the agent translates it into grade, captions, transitions, and pacing you can then adjust piece by piece.
And iterate ruthlessly. The second prompt is where agentic editing beats formula tools: "bigger", "less saturated", "move it to the top", "actually, restore that cut" all operate on the existing edit rather than starting over. The deep dives on captions, music, and speed show more per-job variations, and the AI generation docs cover the generate-and-import family.
Prompts That Won't Work (and What to Ask Instead)
Honesty makes a prompt library useful, so here is what not to bother typing — the agent will decline these rather than pretend:
- "Crossfade between the shots" — no true crossfade dissolves. Ask for one of the 7 transition styles instead (dip to black is the closest feel).
- "Blur his face as he walks across the room" — censoring covers a fixed region and follows through cuts and reframes, but it doesn't motion-track a moving subject. Blur the region where the subject is, per time range.
- "Give me 10 clips from this podcast" — one deliverable per request. Ask for the strongest moment as one directed clip, then request the next.
- "Use my brand font" — no custom font uploads; pick from the 12 bundled fonts (Montserrat and Inter Display cover most brand looks).
- "Clean up the background noise" — no denoise or studio-sound pass. Music ducking and loudness mastering are real; audio restoration isn't.
- "Export the captions as an SRT file" — captions burn into the video; there's no subtitle file import or export.
- "Post it to my TikTok" — exports are downloads at source quality; publishing stays in your hands.
