Didin't find any good webp to mp4 offline converter so i made simple one with Python3. Tested with WSL ubuntu 22.04.5LTS and Windows 11.
Any OS that supports python3
- Python3
- Python3 Pillow
- Python3 Moviepy
- Python3 Argparse
- Python3 Glob2
- FFMPEG
sudo apt-get update
sudo apt-get install python3
pip3 install moviepy pillow argparse glob2
sudo apt-get install ffmpeg
winget install python3
pip3 install moviepy pillow argparse glob2
winget install ffmpeg
Copy videoconvert.py in same folder as webp video files. Test commands (no user inputs default setting is 20framespersecond:
videoconvert.py
python3 videoconvert.py \
| Argument | Description |
|---|---|
--fps 16 |
Video frames per second |
--percent 80 |
Split video into two parts by % |
--output .\folder |
Directory for output MP4 files |
--combine video.mp4 |
Combine multible converted videos to 1 |
--reverse |
Reverse the video playback |
--loop |
Create seamless loop by appending reversed frame sequence |
--log |
Enable logging to webp_converter.log file |
Run test code: python3 videoconvert.py --fps 16
Run test code: python3 videoconvert.py --percent 80
Combined all videos from folder (videos sorted by filename a-z and 1-9), (combining videos may fail if the videos are incompatible with each other, such as having different resolutions)
Run test code: python3 videoconvert.py --fps 16 --combine fullvideo.mp4
This seems to be the best point for reversing videos, since we are just saving and restacking frames in the right order to convert webp to mp4. /
Run test code: python3 videoconvert.py --reverse
Works with stacking video frames normally forward, then immediately playing the same video video backwards and combining these to 1 video file. So you get a basic seamless back‑and‑forth loop.
Run test code: python3 videoconvert.py --loop
Sample looping video:

Run test code: python3 videoconvert.py --log --fps 16 --combine fullvideo.mp4
