FrameGleam

Here is what it looks like in practice.

We asked Claude Code to add travel-vlog style titles to footage shot on a rainy day in Maizuru. On the left is the conversation with Claude Code; on the right is FrameGleam. At the end it also exports a vertical version for TikTok.

About 48 minutes of work, sped up to 3 minutes (no audio). The text is small, so full screen is recommended. The on-screen conversation is in Japanese.

Just ask, and it edits the video for you.

The FrameGleam repository ships with instructions for Claude Code (a skill). When you ask Claude Code to edit a video, Claude reads them first, learns how FrameGleam works, and then gets to work.

Claude turns your footage into stills and looks at them to decide what to keep. It checks the result the same way, with stills and a preview, so all you do is ask and wait.

Before rendering the final video, it shows you the preview and asks whether to go ahead. If you want changes, tell it in words or make them yourself in the editor.

Join the Arashiyama clips in footage/ in the order they were shot. Fade to black between clips, put “Arashiyama” at the start and “Fin” at the end.

Read the FrameGleam skill
Import the clips and sort them by recording time
Look at stills taken every 2 seconds and cut shaky or overlong parts
Add fades between clips and titles at the start and end
Check the fades and titles on stills that match the final render
Render a preview and check that no cut freezes

I've rendered a preview (1:58). I cut the shaky first 3 seconds. Shall I render the final video?

Edit side by side with Claude, in the same editor.

Ask Claude to join the clips, fade between them and add a title, watch it happen in the editor, and fix whatever bothers you as it goes. If you want a bigger rework, ask AI again. Both kinds of edits build up in the same project.

Work at the same time as Claude: Keep the editor open while Claude works. Its edits show up on screen as they happen, and you can step in and fix things yourself. Whoever made an edit, undo takes it back one step at a time, so letting Claude try something costs you nothing.
AI checks its own work: Stills that match the final render (snapshot) and a check that no cut freezes (check) let AI judge the result by looking at it. The bundled skill tells Claude to ask you before rendering the final video.
Premiere-style shortcuts: J/K/L to play, I/O for in and out points, Q/W, Ctrl+K, Ctrl+D and more, so your hands already know the editor.
Extend it with one Ruby file: Add effects, transitions, titles, commands and menu items without touching the core. You can ask AI to write extensions too.

Missing a feature? Add it yourself.

Define the parameters once, and FrameGleam builds the command-line key=value options, a JSON Schema for AI, and the input fields in the editor.

effect test applies your extension to sample footage and returns three stills. AI can write the extension and check it too.

Extensions live in your project's extensions/ folder, so updating FrameGleam won't break them.

FrameGleam.effect :warm_tone do
  label "あたたかい色", en: "Warm Tone"
  param :strength, :float, default: 0.1,
        range: 0.0..0.5, description: "強さ",
        description_en: "Strength"

  filter do |p, ctx|
    "colorbalance=rm=#{p.strength}:bm=#{-p.strength}"
  end
end

A note from the developer

FrameGleam is made by one independent developer. It started because I was tired of joining family videos in shooting order and adding titles by hand every time, so I made it something I could ask AI to do.

The paid plans exist so I can keep doing these things:

Keep the core open source and free to use
Keep it free of ads
Keep shipping updates and bug fixes

You never have to subscribe: the released versions stay free. If FrameGleam turns out to be useful to you, support then would mean a lot.
