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:scene=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...
Re-scaling all images with IrfanView:
File --> Batch Conversion, then select all images, then click on
"advanced", the rest is self-explaining.
