AI Video Editing Tools

Valmera is an agentic AI video editor: upload your footage, describe the edit in plain English, and an AI agent cuts, captions, reframes and polishes it. You export a full-quality MP4. Every page below covers one job, with prompts you can paste and the settings that matter. The eight free utilities at the end run in your browser with no account.

Creating an account and uploading are free. Editing requires a subscription — see plans.

How Every Valmera Tool Works

  1. 1
    Upload your footage
    MP4, MOV, M4V, MKV or WebM, up to 14 GB and 3 hours. Valmera indexes it once: a word-level transcript with speaker labels, shot detection, silences, burned-in text and frame evidence.
  2. 2
    Describe the edit
    Type what you want: “cut the dead air and the ums, add karaoke captions, make it 9:16.” One message can carry several jobs.
  3. 3
    Review the preview
    The agent writes a new version of a non-destructive edit, renders a preview, inspects its own frames and audio, and fixes problems before it reports back. Revise in chat or on the timeline.
  4. 4
    Export the MP4
    Export a full-resolution H.264 MP4 rendered from your original file. Your upload is never modified, and every cut can be restored.

Cleanup & Cutting

Tighten raw footage: dead air, filler words, bad takes, and any cut you can describe in a sentence.

Remove Silence from Video
Cut dead air in one request. Pauses go, a little breathing room stays, and every cut lands on a word edge.
Remove Filler Words
Cut um, uh, er and hmm at their exact word timestamps, plus any words you name, like “like” or “you know”.
Remove Bad Takes & Retakes
Record every attempt in one file. The agent finds repeated lines in the transcript, keeps the best take and cuts the rest.
AI Jump Cut Editor
Turn a talking-head take into tight jump cuts, then punch in, cover with b-roll or leave them clean.
Text-Based Video Editing
Edit against the transcript by describing the change: “cut the sentence about pricing.” The agent finds the words and cuts.
Cut Video Online
Trim the start, remove a middle section or keep one excerpt, by timestamp or by what was said.
Podcast Video Cleanup
Silences, filler words and captions in one request, cut first so captions are timed against the edit.

Shorts & Highlights

Find the moments worth keeping in a long recording and turn them into clips.

Captions & Subtitles

Word-timed captions burned into the video, styled by request and checked against the audio.

Text & Motion Graphics

Designed titles, lower thirds and speech-timed kinetic typography, animated and placed in clear space.

Audio & Music

Music, voiceover and sound effects in a mix that ducks under speech.

Motion, Speed & Transitions

The finishing pass: zooms, speed changes and transitions that make an edit feel produced.

Framing & Aspect Ratio

Reframe for every platform without losing the subject.

Repair & Privacy

Take things out of the picture, or hide them on purpose.

Screen Recordings, B-Roll & Slideshows

Capture a product demo, polish a screen recording, or build a video from photos and clips.

Free Browser Utilities

These run entirely in your browser, with no account and nothing uploaded. They are single-purpose utilities and do not use the editing agent.

Freeze Frame Tool
Hold any frame for 0.3–10 seconds with optional text, then download a video or PNG.
Color Grading Tool
Six preset looks plus exposure, contrast, saturation and temperature for clips up to two minutes.
Subtitle Timing Shifter
Move SRT or VTT cues earlier or later, or fix gradual drift, and download the retimed file.
SRT to VTT Converter
Convert SRT to WebVTT and back, with the header, timestamp separator and BOM handled for you.
Subtitle Reading Speed Checker
Check characters per second, line length and duration of every subtitle against Netflix limits.
Timecode Calculator
Convert timecode, frames and seconds from 23.976 to 60 fps, including drop-frame arithmetic.
Aspect Ratio Calculator
Solve a missing dimension and see what a 16:9 to 9:16 crop or pad costs in pixels.
Video Bitrate Calculator
Solve file size, duration or bitrate from the other two, with audio accounted for.
Audio Loudness Targets
LUFS and true-peak targets by platform, with a gain calculator for your mix.

Frequently Asked Questions

Valmera is an agentic AI video editor for footage you already have. Upload a recording and describe the edit in plain English: the agent cuts silences, filler words and bad takes, adds word-timed captions and on-screen text, reframes to 9:16, adds music, b-roll and sound effects, and repairs the picture by erasing burned-in text or blurring private details. Each page on this index covers one of those jobs.
One editor. Each tool page describes a job you can ask for in the same chat, so a single request can combine several: “remove the silences and filler words, add captions, and make it 9:16.” The agent writes each change as a new version of a non-destructive edit, renders a preview it checks itself, and you revise by chatting or on the timeline.
The eight browser utilities (freeze frame, color grading, subtitle timing, SRT to VTT, timecode, aspect ratio, bitrate and loudness) are free, need no account and run entirely in your browser. For the AI editor, creating an account and uploading are free; editing requires a subscription.
A full-resolution H.264 MP4 rendered from your original upload, with captions and text burned in. Studio exports end with a brief Valmera end card. The free browser utilities download their own files with no end card.

Yes. Valmera's MCP server at https://valmera.io/mcp/server exposes the editing tools to Claude, ChatGPT, Cursor and other MCP clients: 143 tools (live server card, October 2026). An assistant can upload, edit, preview and export the final MP4 over MCP.
No. Studio captions are burned into the video, with no SRT or VTT import or export. If you already have a subtitle file, the free SRT to VTT converter and subtitle timing shifter work on it locally in your browser.
