clever FFmpeg-GUI, small FFmpeg UI, fully portable, no installation.

[ProWo]

When you run Clever, main page has 3 buttons [open, Join, Multiplex]. if you attempted to load a damaged file,
you get an error [This file cannot be analyzed], and 2 buttons disappear [Join, Multiplex]. when you press Ok,
[Join] re-appears but not [Multiplex].

Thx for the hint, fixed.

Frame rate: 21.533 FPS (1024 SPF) in media info output indicates the frame rate and the number of samples per frame.
1024 SPF: There are 1024 samples per frame.
This information is useful for understanding the audio sampling rate relative to the frames.
Audio Frame Rate [AFR] = Audio Sampling Rate [ASR] / Samples Per Frame [SPF] .. or 21.533 = 22,050 / 1024
