I have a folder with PNG images of the following naming scheme:

IMG_0423.png
IMG_0424.png
...
IMG_0509.png

I would like to make an MP4 movie from these images, but I get an error message that ffmpeg cannot find these images:

$ ffmpeg -i IMG_%04d.png -vf "setpts=6*PTS" ../foo.mp4

Is there something I am missing about using this naming scheme with ffmpeg? Thanks for your advice.

EDIT

I am adding the output from running a modified command, which only results in the first frame:

I'm assuming IMG_0423.png is your first image. You have several options (ignoring renaming them) if your images do not start with "1", as in IMG_0001.png for your case.

Use -start_number

You can use the -start_number input option to declare which file should begin the sequence:

ffmpeg -start_number 423 -i IMG_%04d.png … output

Glob pattern

Another option is to use a glob pattern:

ffmpeg -pattern_type glob -i "IMG_*.png" … output

Using a cat

You can pipe images to ffmpeg via cat.

cat *.png | ffmpeg -f image2pipe -c:v png -i - … output

Note that you may have to use a more recent ffmpeg for all of these examples to work. See the FFmpeg Download page for links to builds for Linux, OS X, and Windows.

  • I tried a recent static build, but the output only shows the first frame. Still, I'm getting closer with your approach, thanks.

  • @AlexReynolds Can you update your question with the complete ffmpeg console output that results from your ffmpeg command? It's hard to say what might be going on without the output.

  • I edited my question to include the command I am running, along with output.

  • @AlexReynolds Is there a break in your numbering? Have you tried the other methods I listed? Can you provide a sample of the output?

  • No break. Same result using the glob. Did not try cat. I'll try to upload the movie file to Dropbox a little later when I have my laptop again.

On Windows this was the only thing I could get to work with a bunch of non-sequentially named jpegs (e.g. DMC003.JPG, DMC006.JPG, DMC009.JPG)

  1. Rename to sequential files in Powershell:
dir *.jpg | %{$x=0} {Rename-Item $_ -NewName "Frame$($x.tostring('000000')).jpg"; $x++ }

Then in Anaconda prompt:

ffmpeg -framerate 15 -i Frame%06d.jpg output.mp4

This was using ffmpeg installed with conda:

conda create -n ffmpeg -c conda-forge ffmpeg
conda activate ffmpeg
