FFMPEG fails to find any files matching the regexp

Question

I want to convert sequence of 40 images to a video. The problem is that ffmpeg could not find any of the inputs images matching the regexp in the command. What am I doing wrong please?

I ran the following commands:

> ffmpeg -f image2 -i "img%0d.jpg" -vcodec mpeg4 -y -v "verbose" 07_seq_wire.avi

Thanks for any help!

Answer 1

Try changing img%0d.jpg to img%2d.jpg .

It worked for me when I did this.

You will have to set a bit rate with -b:v 1024K , or a quality level with -q:v 2 (range from 1 to 31, 2–5 being sane choices) to change the quality of the output. Without specifying anything, the default bit rate will be very low and result in bad visual quality.
