VideoFrames

Specify the FPS value from the video and save the frame images with sequential file names.

You can extract frame images with the same settings as before and save them with sequential file names (useful for processing multiple videos under the same conditions).
You need to install FFmpeg.
If ffmpeg is not found, the error "Error: The system cannot find the file specified" occurs.

- The saved file is a JPEG 24-bit color image.
