Skip to main content Module utils Copy item path Source background_filter The ffmpeg filters that paint color behind the (transparent) frames, so the
result is fully opaque. Labels are local to this snippet, so it can be placed
anywhere in a -vf chain or -filter_complex graph. count_pngs_in_zip Count PNG files inside a ZIP archive extract_frame_from_zip Extract a specific PNG frame from a ZIP archive ffmpeg_base_args Arguments every ffmpeg call starts with: no banner, and only warnings unless
verbose_ffmpeg is set. open_output Open the rendered output in the default system viewer run_ffmpeg_for_output Like run_ffmpeg_with_outputoutput file if ffmpeg fails. run_ffmpeg_with_output Run ffmpeg and return its stderr. On failure the error includes the last lines
ffmpeg printed, which usually say what went wrong. run_ffmpeg_with_progress Run ffmpeg, calling on_frame with the number of frames written so far
(from ffmpeg’s -progress output, about twice a second, and once at the end). scan_ffmpeg_stderr unzip_frames Extracts frame_*.png from a ZIP into a temporary folder and returns the
folder path along with the temp directory guard.
