Hi Listers!
Here is a little tooly that I made that may be be of any use to you guys ;
Today, if you want to publish a song, pretty soon they're going to ask
your for "the video". But sometimes you don't have the time / money to
do it. Heck, it's a job. The "Lost Week" video
<https://www.youtube.com/watch?v=O27yC-qLlMM> took me like a (big. Huge)
week to put together, not counting shooting time. BTW it was edited in
KDEnlive, but since No Sister
<https://www.youtube.com/watch?v=7EH9jSnYAGI> (and my Why, Phil show
<https://www.youtube.com/watch?v=2zZO7-wo2_o> and all) I use Blender for
that kind of things now.
Back on topic : You don't have time to put together a proper video for
your shiny new because you have a life and recording the song already
took the best of it lately.
Here is a script
<https://github.com/xaccrocheur/kituu/blob/master/scripts/px-video-maker.sh>
to quickly generate a cool-looking music video
<https://www.youtube.com/watch?v=t-u18CbdjBE>, given the sound file, the
cover artwork image and an optional ending bit :
#!/usr/bin/env bash
FILE_PATH="$1"
FFMPEG="ffmpeg"
ARTIST="$2"
ALBUM="$3"
COVER_FILE_PATH="$4"
EFFECT="$5"
if [ "$#" -ne 5 ]; then
echo "Usage: $0 [audio file path] 'artist name' 'album name'
[artwork image file path] [point|line|p2p|cline]"
exit
fi
convert -resize 1280x720 "${COVER_FILE_PATH}" -background none -gravity
center -extent 1280x720 "${COVER_FILE_PATH}.jpg"
$FFMPEG -y -i "${FILE_PATH}" -loop 1 -i "${COVER_FILE_PATH}.jpg"
-filter_complex "[0:a]
showwaves=s=1280x310:mode=${EFFECT}:r=25,colorkey=0x000000:0.1:0.5[wave];[1:v][wave]
overlay=y=H-h:eval=init[canvas];[canvas]drawtext=fontfile='Jura-Book.ttf':fontsize=60:text='${ARTIST}':x=30:y=(h-70-text_h*2.5):fontcolor=white:shadowy=2:shadowx=2:shadowcolor=black,drawtext=fontfile='Jura-Book.ttf':fontsize=72:text='${ALBUM}':x=20:y=(h-70-text_h):fontcolor=ff6600:shadowy=2:shadowx=2:shadowcolor=black"
-shortest -codec:v libx264 -crf 18 -preset fast -codec:a aac -strict -2
-b:a 192k "${FILE_PATH}-composite.mp4"
if [[ -e "end.mp4" ]]; then
$FFMPEG -y -i "${FILE_PATH}-composite.mp4" -i "end.mp4"
-filter_complex "[0:0] [0:1] [1:0] [1:1] concat=n=2:v=1:a=1 [v] [a]"
-map "[v]" -map "[a]" "${ARTIST}-${ALBUM}.mp4"
rm -rf "${FILE_PATH}-composite.mp4"
else
mv "${FILE_PATH}-composite.mp4" "${ARTIST}-${ALBUM}.mp4"
fi
rm -rf "${COVER_FILE_PATH}.jpg"
echo -e "
################################################
DONE : ${ARTIST}-${ALBUM}.mp4"
This will
* Take the (PNG) cover, and center it inside a 1280x720 (AKA 720p)
pixels video ;
* Generate a "wave" of the (WAV) sound file ;
* Print "Artist" in Orange, And then "Title" in White, below,
slightly
bigger and offset to the left ;
* Merge the 3 together ;
* If there exists a file named "end.mp4" in the directory, append it
to the final video ;
* Clean up everything, and produce a file named "Artist-Title.mp4" in
720p.
Notes:
* This script depends on the ffmpeg and imagemagick packages
* The last argument is the style of the dancing waveform, take a short
audio file to experiment with all 4 of them
* The "end.mp4" file is optional, it's there if you want an ending
credit / legal / whatever bit, or a nice fade out, anything. It's
scaled to fit.
* If there is a "Jura-Book.ttf" font file in the directory from which
the script is invoked, it will be used, otherwise your default serif
font will be.
With it, you can make that kind of music video
<https://www.youtube.com/watch?v=t-u18CbdjBE> ; hope it's useful, cheers
everybody, keep on rocking it!
