Hmm,.. can't reproduce the issue here.
I used a source with 25fps and 429 frames.
aiming for 50/1 I get 50fps and 858 frames.
aiming for 60/1 I get 60fps and 1030 frames.
aiming for 60000/1001 I get 59.9401 fps and 1029 frames.
-> looks all fine.
Doing the calculation: 4838/25*60000/1001 ~ 11599,6 so the calculation is correct.
Is your source vfr?
Have you tried LibavSource instead of FFmpegSource?
Load your source, make your settings, set output path, enable debug output, open Avisynth Preview, disable debug output, zip/rar/7z the debug output, share the debug output with me.
