[suggestion] is possible to have the "compare" images on the same place

[Bartoloni]

right now the vaporsynth comparison of a vaporsynth preview frame is like that: http://www.wcn.it/hack.mp4

can be very useful if can be possible to have a button (on gui .. and maybe with a keyboard key to not move eyes from the picture) to switch from original image to the vaporsynth one on the same position, without any black flash... just swapping the 2 frames ..
this can make very very easy to understand the modifications appied by the filter.

usually , right now i have to extract 1 frame from the 2 output videos and compare them using the Windows image viewer and left/right arrows ... and seems that this is the best way to be sure to understand what i gained by the filter and what i loss...

It's already possible.
See:
"Filtering->Vapoursynth->Misc->Preview->Split Compare view"-Options
"Filtering->Avisynth->Misc->Preview->SplitView->Placement"-Options
you probably want 'interleaved'.
