ffmpeg video from images

One frequent taks that comes up is to combine a sequence of images into a video. Like most things dealing with video, ffmpeg is one good solution.

Here is a single line command which takes a number of images and combines them into a video.

ffmpeg -framerate 24 -pattern_type glob -i './corrected/*.jpg' -c:v libx264 -r 30 -pix_fmt yuv420p corrected.mp4

An additional ability is it add an overlay to the images prior to combining them into a video. For example, one might want to add a timestamp onto the images. Here we read images with names *_ms.jpg then add a portion of the filename (timestamp) to the image.

for infile in *_ms.jpg; do 
    overlay=$(echo ${infile} | cut -d . -f 1)
    outfile="./corrected/mod_${overlay}.jpg"

    echo "Input File: $infile Output File: $outfile"
    ffmpeg -i ${infile} -vf "drawtext=text=${infile}: x=5: y=5: fontsize=24: fontcolor=yellow@0.9" ${outfile}
done

A bash script that does this is available on Github.
