Hello,
For some here the answer will probably be know right away. That is why I am writing, after long googling.
I would like to create a sort of video presentation from images. However, I would like that every slide (image) is displayed for a different time duration. This is just the first step; next i would like to combine voice with that, but it is probably another problem, for later.
Hence, I have a sequence of images y-%2d.png
The following works for me:
ffmpeg -framerate 1/10 -i y-%2d.png -c:v mpeg4 -vf "fps=2,format=yuv420p" out.mp4
And the following works, too:
ffmpeg -r 1/2 -start_number 7 -i y-%2d.png -c:v mpeg4 -vf "fps=2,format=yuv420p" out.mp4
However, how to control the time of displaying individual images? Is that possible at all?
I thought that something like this may work:
ffmpeg -r 1/5 -i y-01.png -r 1 -i y-02.png -c:v mpeg4 -vf "fps=2,format=yuv420p" out.mp4
It does not. The first image is displayed, only.
Kind regards from Poland, zb.
I have used PhotoFilmStrip and also Imagination. One of them does the individual time duration, can't remember which. John.
