Adds a shard transition to a talking-head video: triangles snap in across the frame from one corner and out again, then a chapter card names the new part. Timed to the words they say, on their own footage, with their sound kept; 16:9, 9:16, 1:1 or 4:5. Renders locally with Chrome and ffmpeg: no video model, no key and no cost. Use when someone wants a sharper, more graphic transition between parts of a video (a review, a breakdown, a tech explainer).

About this skill

You say

In talk.mp4, put a shard transition before "After one quarter".

It said back

I added the shard transition before "After one quarter" and rendered it to talk-graphics.mp4. It's 1920x1080, 30 fps and 24.3 s long, with your original sound unchanged. I checked the layout and it reported no problems, but I didn't open the check frames or the rendered video, so I haven't looked at how it reads.

  • Shard wipe: triangles snap in from the corner at 17.0 s and clear by 18.2 s.
  • Chapter card: reads "Part 3 – After one quarter", with "quarter" highlighted. It covers the frame from 17.2 s to 19.7 s while the speaker keeps talking.
  • Timing: they say "After one quarter" at 17.58 s, so the wipe starts about 0.6 s before it and the card is already up when the words are spoken. I gave both beats fixed times rather than tying them to the words.
  • Look: paper, the default warm off-white panels with a tomato accent. I left the face position at the tool's default of [50, 38].

Our 1 runs took 1 min 43 s to 1 min 43 s and $0.08 to $0.08 of API use each, in Claude Code with claude-sonnet-5-5. On a Claude plan, a run counts toward your usage instead.

Do I have to name Shard Transition to use it?

Type /shard-transition-overlay first to make sure it loads. Without it, Claude Code may judge a small job simple enough to do without the skill.
