Thank,
I have a backup of the framsets, so no panic. :)
But then why is asking to overwrite? Why does the ffmpeg try to
overwrite? Here the command without "-y":
mcll@mcllserver-i3:/home/VVCam$ ffmpeg -framerate 25 -i
000_Images/2022/04/2022-04-10/*.jpeg -c:v libx264 -profile:v high -crf
20 -pix_fmt yuv420p output.mp4

Hi,
I have about 4300 pictures in a folder (000_Images/2022/04/2022-04-10/).
I want to create a video from them, every picture should be one frame in
the video.
I'm using the following command: ffmpeg -framerate 25 -i
000_Images/2022/04/2022-04-10/*.jpeg -c:v libx264 -profile:v high -crf
20 -pix_fmt yuv420p -y output.mp4
Its starting, but after about 500 pictures ffmpeg is slowing down, while
the system load goes quickly up. It was hard to cancel the command, as
the load was above 80. :)
Here some log of the command:
mcll@mcllserver-i3:/home/VVCam$ ffmpeg -framerate 25 -i

Why is this generating such a high load, and what should i do?
It is for some reason creating separate streams for each jpeg image.
Is your ffmpeg modified or you use script?
Because original ffmpeg does not do this.
Ignore that remark above, I forgot -y switch.
Oops, using -y switch in your case is very dangerous.
You completely ditched all jpegs and replaced them with the first one.
NEVER EVER USE -y SWITCH, NEVER EVER.
Thanks
