MeGUI: Encoded video has only ONE frame with this particular sample

[mmatz]

Hello everyone.

I have been using MeGUI for a few years now.
Each time I encode a video, I press CTRL+R, choose a video input,
open it as DirectShowSouce, set resize resolution, and save the AviSynth script.
After that I just choose my predefined x264 encoder setting, queue the job, and start it.

It always worked as I wanted it to, i.e. as it was supposed to,
always until I wanted to encode this particular sample:

The problem is, after I encode it as described above, the result is a video
that consists only of the first frame of the original video.

Final resolution, duration and quality are as they are supposed to be,
but the video itself is just one single static frame, nothing more.

If anyone knows what I should do to fix this,
or just explain me why is this happening, I would be grateful.

Thanks in advance.
