I tried to search for this issue here, but either the new UI has a lame search engine or I'm getting old (maybe both).
I've always been annoyed by how frames seem to jump around when stepping back thru
recorded video frame-by-frame (in the console or the stock web UI and even UI2.htm)
Currently on BI 4.5.2.7, but have noticed this since way back in the early 4.x days...
It's as if the math used to calculate the frame offset from the i-frame
is somehow out of whack when stepping backwards. I record to BVR format (direct to disk),
and it happens with all my cams (Hikvisions and Huisin mini-ptz's,
all set to 10FPS & i-frame every 10 frames, ie, 1 per second)
I've made a recording of this effect which i hope illustrates the issue:

i first play thru the clip, then hit the step-back button repeatedly until the car is out of frame again,
then step forward, then back again.
Is this a known issue? Has anyone else around here noticed/reported it?
It's not that big a deal, cuz I can always find the frame i need by stepping thru it forward,
but it sure would be nice to have reverse step-back work just as well...
I've emailed BI support, but am not on a plan, so who knows if/when Ken will read it or do anything about this.
Thanx, Paul.
