delay not changing fps of mp4 file

[mitchellsf]

I'm trying to change the frame rate of a video using convert. This is the command I am using:

convert -delay 1 video1.mp4 video2.mp4

However, no matter what number I put for the delay, the frame rate does not change (it is stuck at 25 fps). I want it to be 100 fps. I am using the latest IM version for windows: ImageMagick-7.0.8-Q16.

Why is the delay not working?

Thank you!

Try using ffmpeg directly.
