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 -del         


        

Answer 1

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

Answer 2

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

Answer 3

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.

Answer 4

sudo apt install ffmpeg

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

Answer 5

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
