    Yes, I make these with Kdenlive! I have been putting off finishing the tutorial I have been working on creating, but in short:

    1. Import video into Kdenlive
    2. Use Title Clips to add text
    3. Use various Effects (mainly Transform) to animate the text
    4. Render as MP4
    5. Use ffmpeg to convert the MP4 to WEBP or GIF
    6. Use gifski and gifsicle to further compress the GIF (the WEBP is fine as-is)

    Here is a bash script that I wrote to use ffmpeg/gifski/gifsicle to convert all MP4 files in the current directory:

    bash 
    #!/usr/bin/env bash

#prerequisites:
#  ffmpeg
#  gifski
#  gifsicle

# creates animated images out of all MP4 files
# in the working directory, as well as creating
# a thumbnail out of one frame
# if argument passed to script, the thumbnail
# will be created out of that frame, but none of
# the animated files will be created

# pass an argument to this script to specify
# which frame to use as the thumbnail
# if none passed, use default
if [[ $1 == "" ]]; then
    frame=0.85
else
    frame=$1
fi

# frame passed must be decimal < 1.0 and >= 0.0
if ! ([[ $frame =~ 0\.[0-9]+ ]]); then
    echo frame passed: $frame
else
    # loop through all MP4 files in directory
    for file in *.mp4
    do
        # only proceed if file found
        if [[ $file != *"*"* ]]; then
            # create paths
            input_path=$(pwd)/"$file"
            output_path_animated=${input_path%.*}.webp
            output_path_animated_low=${input_path%.*}-low.webp
            output_path_gif=${input_path%.*}.gif
            output_path_thumb=${input_path%.*}_thumb.webp

            # determine the exact frame to use as thumbnail
            frames_total=$(ffprobe -v error -select_streams v:0 -count_packets -show_entries stream=nb_read_packets -of csv=p=0 "$input_path")
            thumb_frame=$(awk -vnumber="$(awk -v var1=$frames_total 'BEGIN { print (var1 * '$frame') }')" -vdiv="1" 'function ceiling(x){return x%1 ? int(x)+1 : x} BEGIN{ print ceiling(number/div) }')

            # if argument had been passed to script, skip creating
            # animated images and ONLY create thumbnail
            if [[ $1 == "" ]]; then
                #full webp
