Is there a setting to keep the original filenames (or at least a version of them)?

For example, if I have a few dozen differently-named files, it drops the converted ones into folders with those names - but names all of the files the same, so I have to rename every single one by hand.

Is there an easy way around this? I'd like to have something like "filename_60" or "filename_120."

To add to this, if you can eventually add a filename template that would be great, at least for the major settings.

For example (taking 3 parameters out of many):

* = original filename

$MP4Q = MP4 encoding quality

$OUT = Output FPS

With the result of = *_$MP4Q_$OUT will generate "<original filename>_23_100_noaudio.mp4" and "<original filename>_23_100_audio.mp4"

Fantastic program! Thank you for your amazing effort.
