1 frame delay

I have the following problem with VideoAI (since a few versions).
In compare mode, when on the left screen half there is one enhancement and on the right screen half there is another enhancement, everything is ok. I can compare exactly left and right side.
But when I switch off the compare mode and go to side by side mode, where on the left half there is the original and on the right half there is an enhanced version (after pressing “preview”),
I cannot exactly compare, because the right side has a delay of 1 frame.
How can I overcome this problem?
Thanks in advance and kind regards - Helmut

Depending on the model being applied, there can be a frame difference as the models are trying to read and interpret the footage. You will not be able to get an exact frame to frame match in the split screen view at all times.
