I have a few hundreds of still images. The files are named according to the Canon convention - IMG_2501.JPG, IMG_2502.JPG, IMG_2503.JPG, ....

I've tried:

% avconv -f image2 -i IMG_%04d.JPG avconv_out.avi

avconv version 0.8.9-6:0.8.9-0ubuntu0.13.10.1, Copyright (c) 2000-2013 the Libav developers
built on Nov  9 2013 19:09:46 with gcc 4.8.1
IMG_%04d.JPG: No such file or directory

I guess that IMG_%04d.JPG is not found because avconv expects IMG_0000.JPG, IMG_0001.JPG, .... I can create a symlink for that, but it's a really ugly hack.

How do I create a video from these still photos using avconv without renaming?

  • What about adding avconv -start_number 2501 -f image2 -i ... ? – jmunsch Dec 27 '13 at 17:26
  • It will probably fail if a picture is missing from the sequence, which happens every now and then (I stop the camera, make a few calibration pictures, delete them and continue). – Adam Matan Dec 30 '13 at 16:31

Try to rename them first

a=1
for i in *.JPG; do
  new=$(printf "%04d.JPG" ${a}) #04 pad to length of 4
  mv ${i} ${new}
  let a=a+1
done

    A better approach would be to create links, which will keep the filenames the same (it matters to some people), in this case substitute mv for ln. You can then do the conversion and delete all the links. – v010dya Nov 10 '14 at 9:30
