I have to cut a part from four files and concatenate them together.
At the moment I am doing that in the following way:
time ffmpeg -i 00250.MTS -i Pictures/reiger.jpg
\
-ss 00:19 -to 02:41
\
-filter_complex "[0:v][1:v]
overlay=W-w-10:10:enable='between(t, 73, 106)'" \
-pix_fmt yuv420p -acodec copy -vcodec libx264 -preset veryfast
-crf 26 \
hetOnmogelijkeDoen.mp4
time ffmpeg -y -i 00264.MTS \
-ss 00:08 \
-to 00:17 \
-acodec copy \
-vcodec libx264 \
-preset veryfast \
audio1.mp4
time ffmpeg -y -i 00265.MTS \
-ss 00:04 \
-to 00:17 \
-acodec copy \
-vcodec libx264 \
-preset veryfast \
audio2.mp4
time ffmpeg -y -i 00266.MTS \
-ss 00:06 \
-to 00:15 \
-acodec copy \
-vcodec libx264 \
-preset veryfast \
audio3.mp4
time ffmpeg -y -i 00267.MTS \
-ss 00:08 \
-to 00:16 \
-acodec copy \
-vcodec libx264 \
-preset veryfast \
audio4.mp4
time ffmpeg -y -i audio1.mp4 -i audio2.mp4 -i audio3.mp4 -i audio4.mp4 \
-filter_complex "[0:v][0:a][1:v][1:a][2:v][2:a][3:v][3:a]
concat=n=4:v=1:a=1[v][a]" \
-map "[v]" -map "[a]" \
-vcodec libx264 -preset veryfast \
mergedAudio.mp4
I was wondering if this is the correct way to do this.
I especially would like to know if it could be done in one swoop. Now
the video is converted two times.
