Combine multiple images to form a strip of images ffmpeg

Question

I wish to combine multiple images into a single strip of images, using FFMPEG.

I have been trying to search this thing on google, but unable to find anything useful. All links take me to places where multiple images are combined to give a video output.

Assuming that all the files are of the same width and height, how can I join them to get a single strip of images. Can anybody help me?

Solution 1

Use the tile filter

Using the scale and tile video filters with input files 001.png to 005.png:

ffmpeg -i %03d.png -filter_complex "scale=120:-1,tile=5x1" output.png

If you have file names that are in a non-numbered sequential order you can use the glob pattern type (not supported by Windows):

ffmpeg -pattern_type glob -i "*.png" -filter_complex tile=5x1 output.png

Margin / border

You can also add a margin (outer border space) and padding (space between frames):

ffmpeg -i %03d.png -filter_complex "scale=120:-1,tile=5x1:margin=10:padding=4" output.png

Default color is black. Add the color option if you want to change the border/margin color:

ffmpeg -i %03d.png -filter_complex "scale=120:-1,tile=5x1:margin=10:padding=4:color=white" output.png

A vertical orientation is possible. tile=1x5 for this example:

More info

See the tile filter documentation.

Solution 2

If you've got do it with ffmpeg then I don't know. If you want to get the job done and are willing to use another program suitable for the task then convert is part of ImageMagick.

convert sepimage-0.png sepimage-1.png sepimage-2.png -channel RGB \
-combine imagecopy.png

Number of images would be variable. It can range from 10 to several 100s. And I want a horizontal strip.

The images need to be the same size, otherwise the output just creates duplicates of the images.

I'm using your command but the result I'm getting is (only first image is shown, all other are black): i.ibb.co/zPgPJ0V/Untitled.png

@user2988257 I can't duplicate that behavior. Provide a link to a pastebin that shows your full command and the complete console output.

@llogan If I have single image then How can I create tile from that?

[Elisa Cha Cha]

@AbhayKoradiya ffmpeg -i input.jpg -i input.jpg -i input.jpg -filter_complex "[0][1][2]hstack=inputs=3" -vframes 1 output.jpg See Vertically or horizontally stack (mosaic) several videos using ffmpeg?

how can i set the color of the padding to be white?

[Elisa Cha Cha]

@Kong According to the tile filter documentation use the color option: ffmpeg -i %03d.png -filter_complex "scale=120:-1,tile=5x1:margin=10:padding=4:color=white" output.png

I wanted to simply tile images together without reducing image quality and found this post. I modified it for my task using: ffmpeg -i %03d.png -filter_complex "tile=5x1" tiled.png What a great function: just by changing tile to untile you reverse the effect, and using 1x5 gives you vertical stitching.

Yes, this is definitely a job for ImageMagick, not ffmpeg! stackoverflow.com/questions/20737061/…
