New page

Using ffmpeg to convert a list of files with timestamped filenames into an mpeg video

Change the line "for f in $( ls drone*.bmp ); do" to filter the images to be used - here "drone*.bmp"

The last filename in the ffmpeg line to the destination name.

#! /bin/bash
let COUNTER=1000000

echo convert $f path$COUNTER.png
convert $f path$COUNTER.png
let PREV=$COUNTER
let COUNTER+=1
# use same image again to lower framerate
convert $f path$COUNTER.png
let PREV=$COUNTER
let COUNTER+=1
