convert all the png files in a folder to video

Question

I have ~450 frames named 1...450. However, there are some missing frames for example frame 10, 30, and so on do not exists.

I want to create an AVI video in the same order as 1...450.png. How should I do that?

Option 1: Rename

First rename all of the inputs so they have zero-padding (001.png...450.png).

Then run ffmpeg:

ffmpeg -framerate 25 -i %03d.png output.avi

or

ffmpeg -framerate 25 -pattern_type glob -i "*.png" output.avi

Use a more complicated command to sort the files and then pipe to ffmpeg:

cat $(find . -maxdepth 1 -name "*.png" | sort -V) | ffmpeg -framerate 25 -i - output.avi

if I use sort, I don't need to use zero-padding right? – Mona Jalal Nov 10 '19 at 18:22
@MonaJalal Yes. You can run find . -maxdepth 1 -name "*.png" | sort -V and it will show you the order that will be given to ffmpeg. – llogan Nov 11 '19 at 19:19
