Combine images into video (with audio in background) in ffmpeg

I have a folder with 15 images and 1 audio file:

image_1.jpg, image_2.jpg, image_3.jpg ..... and music.webm

(Also resolution of images is 1440x720)

I want to combine these images into a video with audio in background.And framerate I require is 0.2 (5 second for each frame).I gave a search on Stackoverflow and I found the nearest example and tried.But it failed.

ffmpeg -f image2 -i image%03d.jpg -i music.webm output.mp4

(Actually I have very little knowledge of ffmpeg so please excuse my foolishness)

Please help me with my issue.(Also I didn't understood where in the code I have to enter framerate)

Edit:-If needed I can easily tweak with filename of images.Be free to tell me that too

How your command failed? please paste the text.

According to your image file format, the pattern should be: %3d, but not %03d

e.g.

  • image_%d.jpg apply to: image_1.jpg, image_2.jpg, image_3.jpg
  • image_%04d.jpg apply to: image_0001.jpg, image_0002.jpg ... image9999.jpg

and also , when using this "pattern sequence", MAKE SURE:

  1. the sequence should start from xxx001.jpg, otherwise you should specify a parameter -start_index or something.
  2. the sequence must not broken. e.g. image5.jpg, image6.jpg, (missing 7 ) image8.jpg

Try this:

ffmpeg -r 0.2 -i image_%02d.jpg -i music.webm -vcodec libx264 -crf 25 -preset veryslow -acodec copy video.mkv

So -r specifies fps (I actually didn't try using a float value there, but try it)

-vcodec specifies video codec, -crf quality, preset the encoding speed (slower is more efficient), -acodec copy says audio should be copied.

I think that should work, give it a try. You will need to rename the images to image_01.jpg image_02...
