v1.2.1

Release 1.2.1

Manual media tools setup

• The extension no longer downloads, extracts or installs FFmpeg. Settings → Media tools
  replaces in-panel installation with a manual setup guide: Open download page opens the
  exact release page in your browser, and the card shows the archive name and its SHA-256 with a
  copy button.
• Enter the extracted bin folder and choose Use folder. Both programs are verified against
  their fixed digests before the selection is saved. A supported pair in your Python environment
  or on PATH is still found automatically; choose Check again after changing PATH.
• A ? button beside Media tools explains download, checksum verification (with Windows
  commands), extraction, folder selection and why other builds are refused. It is available in
  English, Traditional Chinese and Simplified Chinese.
• After you select the tools, retry the original media action yourself; it is not resumed
  automatically.
• Clean up known earlier setup leftovers only when requested, preserving unknown files and any
  parked runtime without a verified replacement.

Sequence assembly fix

• Sequences built from your own ComfyUI video generations now assemble. Earlier versions
  refused these segments: first because of the color tag ComfyUI writes into its video files,
  and then, for 5-second and 15-second segments, because the file states its length rounded to
  the millisecond.
• Segments with that color tag are converted to the standard video color space while they are
  prepared for assembly. Segments that are already standard are prepared as before.

Upgrade and limits

Replace the complete package, restart ComfyUI and refresh the browser. Tools that 1.2.0 or an
earlier version already installed are still discovered and verified; no action is needed. The
supported build, platforms and project format are unchanged from 1.2.0.
