# This script is designed to help you automatically select the correct intro
|
|
# and outro files (prerendered with built-in fades) and the correct chunks
|
|
# of a chunked recording (e.g. OBS with automatic split every 5 minutes).
|
|
# It will open the first and last chunk in mpv if you want, so that you
|
|
# can find the start and end points (in seconds), you manually need to transfer
|
|
# them into the script for now (no idea how to convince mpv to output it).
|
|
# After that the script will render the introfile with the first chunk and the
|
|
# last chunk with the outrofile, and then in the last step assemble everything
|
|
# into the final recording with audio normalization.
