FFMPEG

From ffmpeg.org:
“FFmpeg is the leading multimedia framework, able to decode, encode, transcode, mux, demux, stream, filter and play pretty much anything that humans and machines have created. It supports the most obscure ancient formats up to the cutting edge. No matter if they were designed by some standards committee, the community or a corporation.”

These applescripts run the FFmpeg command behind the scenes so you don’t have to learn the formatting.

You will need to download and install FFmpeg and FFprobe from ffmpeg.org or use Homebrew so they already exists on your computer. Typical install locations are:
/usr/local/bin/
or
/opt/homebrew/bin/

More detailed installation instructions should arrive via email after purchase.
