Hi
I tried the fading between pictures and cropping to there original
size (5152 x 3864), so that they are not distorted
ffmpeg -y -i %%02d.JPG -i SligoAir_WhiteBlanket.mp3 ^ -vf
zoompan=d=10:fps=1,framerate=fps=25:interp_start=0:interp_end=255:sc
en
e=100 ^ -pix_fmt yuv420p -s 5152x3864 out.mp4
It seems that -s 5152x3864 destroy the fading effect achieved with
the second line
How can I correct this ?
You must bring all pictures to the same size _before_ you read them with
FFmpeg.
Re-scaling one image with FFmpeg:
ffmpeg -i input.jpg -s 5152x3864 output.jpg Re-scaling all images
with FFmpeg:
I think that's only possible with a loop in a script. Too complicated.
Re-scaling one image with IrfanView:
Open the image, Image --> Resize/Resample, Save as...

But my individual pictures are already at 5152x3864. The problem is
that when I do the above command without -s ...x... they are stretched in the
horizontal axis
What should be the size to use for my pictures to be displayed without
distortion ?
The zoompan filter automatically rescales its input to 1280x720.
Override it by adding `s=5152x3864` as an option to the zoompan filter.
Remove the `-s` option from the command.

Gyan
