about · usage

Generates a two-pass FFmpeg command to convert image sequences into WebM videos using the VP9 codec. Originally created to simplify video generation from Stable Diffusion outputs and other image-sequence workflows.

How to use

  1. Place all your images in a single directory with sequential numbering (00001, 00002, etc.)
  2. Enter the filename suffix (e.g. -frame.png for files like 00001-frame.png)
  3. Configure frame rate, quality (CRF), and output filename above
  4. Copy the generated command
  5. Navigate to your image directory in a terminal
  6. Paste and execute the command

Filename examples

  • suffix -frame.png → 00001-frame.png, 00002-frame.png, …
  • suffix .jpg → 00001.jpg, 00002.jpg, …
