[FFmpeg-user] Image to Video conversion

[Naveen.B]

Hello,

I have an .bmp Image with resolution 1600x1300x24-bit, each file size comes
around 6Mbps, I have 30 such files (Image-1 ....Image-30) in a directory.
I converted those images to a video @ 30fps for length of 1 second using
the below ffmpeg command, the video file size turned out to be around 189kb
and In the command I am not doing any compression.
I expected the converted video size to be 30 Image file x 6Mbps = 180 Mbps,
am I doing anything wrong in the command?

*ffmpeg -framerate 30 -i CapturedImage-%03d.bmp -pix_fmt yuv420p
rawImage.mp4*

Kind Regards,
Naveen B.
