to_vp9

This Script is unfinished and not ready for usage.

This script converts all videostreams in all files with given file extension in your current working directory and all subdirectories to vp9. The standard settings are in my opinion good for personal storage of movies. Feel free to change them or suggest changes. Later there will be options in the script to change the default behavior.

If used on containers with subtitles or audiostreams, this skript will only convert the videostream and copy the other streams in a Matroska container.

Encoders

Hardware-Encoders using NVENC, VAAPI or QSV depend on your hardware and an enabled Hardware video acceleration. So not all encoders will be available.
