Trying to convert 200 jpg files to an mp4 w/ ImageMagick. Receiving the same error over and over again

Question

I'm trying to convert 200 .jpg files that were .ppm files into one .mp4 file.

In the same directory as the .jpg files, I ran this code:

convert -delay 6 -quality 95 test*ppm movie.mp4

and received this error message:

convert: no images defined `movie.mp4' @ error/convert.c/ConvertImageCommand/3210.

What caused this error?

Solution 1

Nevermind, I just ended up using ffmpeg. This is the code that I used:

ffmpeg -framerate 1 -pattern_type glob -i '*.jpg' -c:v libx264 out.mp4

Solution 2

sudo apt install ffmpeg

---

ImageMagick delegates video processing. I lost more than 5 hours to understand why such a bug NotIdentifiedByImageMagickError

Solution 3

From what I am reading the images you are running the command on have a .jpg extension.

Try

convert -delay 6 -quality 95 *.jpg movie.mp4

Sadly, I receive the error: convert: delegate failed `"avconv" -v -1 -i "%M%%d.jpg" "%u.%m" 2> "%Z"' @ error/delegate.c/InvokeDelegate/1310.

glob is defined in the POSIX standard and it's not available on Windows by default.

convert -delay 600 *.png movie.mp4 worked on my side (600 means 6 seconds)

What does -pattern_type glob and -c:v do?
