I have a series of 15 PNG Files - https://www.sendspace.com/file/jrpbl1.
I would like to create an MP4 Video of them using FFMPEG.
In my video I'd like to have 15 Frames (One per image) where each is played 1 Sec (FPS 1).
I downloaded the latest FFMPEG for Windows (Version 3.2.4).
I followed the guide FFMPEG - Slideshow.
The command line I used is ffmpeg -framerate 1 -i NR_1_%05d.png -c:v libx264 -crf 15 -pix_fmt yuv420p out.mp4
.
I also tried ffmpeg -r 1 -i NR_1_%05d.png -c:v libx264 -crf 15 -pix_fmt yuv420p out.mp4
(What's the difference between -r 1
and -framerate 1
?).
Yet the resulted video is not as expected.
The first frame is black and then there is only one image as constant (I watch it on VLC Media Player).
Any idea how to product it correctly on Windows?
Thank You.
