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?

Do the images in the directory you are running the command from have a .jpg extension? — Bryan Reilly, Aug 03 '15 at 03:35
Do you have ffmpeg as a delegate in your ImageMagick install. MPEG formats require that ImageMagick have ffmpeg as a delegate library. You should see mpeg listed in Delegates section from `convert -version`. See the comment in the MPEG section of http://www.imagemagick.org/script/formats.php#supported — fmw42, May 09 '18 at 00:16

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

glob is defined in the POSIX standard and it's not available on Windows by default. – Franck Dernoncourt Jul 06 '17 at 18:24
What does `-pattern_type glob` and `-c:v` do? – tommy.carstensen Nov 25 '20 at 03:07

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.` – fmartin Aug 03 '15 at 03:45
`convert -delay 600 *.png movie.mp4` worked on my side (600 means 6 seconds) – Franck Dernoncourt Jul 06 '17 at 18:26

sudo apt install ffmpeg

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

TL;DR

Use \ls or ls --color=never to get uncolored files list

Failing command...

for f in $( ls *.JPG ); do convert -resize 1920x $f re_$f ; done

... becomes

for f in $( ls --color=never *.JPG ); do convert -resize 1920x $f re_$f ; done

Details

I got same error, due to colored output of ls command :

Error I got (in french):

$ for f in $( ls *.JPG ); do convert -resize 1920x $f re_$f ; done
convert: pas de délégué pour décoder ce format d'image `JPG' @ error/constitute.c/ReadImage/501.
convert: pas d'images définies `IMG_5235.JPG' @ error/convert.c/ConvertImageCommand/3210.
convert: impossible d'ouvrir l'image `IMG_5236.JPG': Aucun fichier ou dossier de ce type @ error/blob.c/OpenBlob/2712.

Filenames are colored like in this screenshot :

My ls command is aliased to a ls --color=auto which leads convert file parameters to contain color sequences.

Disable ls colored output by using \ls :

for f in $( \ls *.JPG ); do convert -resize 1920x $f re_$f ; done

or :

for f in $( ls --color=never *.JPG ); do convert -resize 1920x $f re_$f ; done

Then convert may not give previous errors. Hope this can help.

The proper syntax is:

convert src_file [options] dst_file

So in your case, it should be like:

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