I'm trying to compile one .webm file that contains this:
I was unable to find out how/if the concatenate functionality of ffmpeg could do such a thing. Any clues?
You can use the concat filter.
ffmpeg \
-loop 1 -framerate 24 -t 10 -i image1.jpg \
-i video.mp4 \
-loop 1 -framerate 24 -t 10 -i image2.jpg \
-loop 1 -framerate 24 -t 10 -i image3.jpg \
-filter_complex "[0][1][2][3]concat=n=4:v=1:a=0" out.mp4
-framerate
with frame rate from video.mp4
.If there is audio in video.mp4
you'll need to provide audio for the images as well for it to be able to concatenate. Example of generating silence:
ffmpeg \
-loop 1 -framerate 24 -t 10 -i image1.jpg \
-i video.mp4 \
-loop 1 -framerate 24 -t 10 -i image2.jpg \
-loop 1 -framerate 24 -t 10 -i image3.jpg \
-f lavfi -t 0.1 -i anullsrc=channel_layout=stereo:sample_rate=44100 \
-filter_complex "[0:v][4:a][1:v][1:a][2:v][4:a][3:v][4:a]concat=n=4:v=1:a=1" out.mp4
channel_layout
with audio channel layout (stereo, mono, 5.1, etc) from video.mp4
.sample_rate
with audio sample rate from video.mp4
.-t
duration from anullsrc
with any associated video input: the concat filter will automatically pad it to match video duration.If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
