Editing With Code Instead of CapCut: Seedance 2.5 Generation + Claude Code Effects

AI creator Prompt_what (@Promptwhat) says he cancelled a paid editing-tool subscription and switched to code-based editing. The workflow: hand over a talking video plus motion references, and let Claude Code draw the caption effects in code. This article summarizes the outline the author published on X; the actual conversation logs and command sources said to be in the replies are out of scope here.

The author's stated setup: Seedance 2.5 generates, Claude Code edits

The combination the author described for this piece:

  • Talking video: generated in one 30-second pass with Seedance 2.5
  • Editing and effects: delegated to Claude Code
  • Time spent: about an hour, mostly waiting on generation and rendering

The three effect examples the author named: large type passing behind the person, cards popping up in sync with words, and a self-typing input box. Per the author, all of these are "drawn entirely in code," and the claim is that no After Effects knowledge is needed.

Reusable structure: build the template once, swap topics after

The point of this workflow is not one-off editing but templatization. According to the author, once the template is built, later videos only need a topic swap, which makes fairly high-quality video automation possible.

How it surfaced: @ramztd quoted the post on October 3, 2026, writing (in Korean) that Claude Code handles editing well lately and pointing readers to Prompt_what's prompts. The original author said the process and actual conversation are in the replies, but those reply-thread logs and command sources are not included in this summary. To follow the actual prompts and code, check the reply thread on the original post directly.
