Here is my command, it's to cut he last 20 seconds of a video.

```
ffmpeg -y -sseof -20 -i  record.mp4 -vcodec libx264 -crf 27 -preset veryfast output.mp4

```

It works perfectly, but I would like to have to same command, for cutting the last 20 seconds of the last file created with .mp4 extension in the folder. Thanks if you can help me.

Edit : OS is Windows
