Hi Ethan,
Two Reason why I ask.
1) I am curious to know the maxmium possibility. As VMSes specify how many frames can be recorded per second per NVR/DVR but not maxium playback rate.
2) Smooth playback even at high frame rate is easier to identify an incident and is more "fun" to watch! when you are playing back video I think it is important for there to be a guarenteed consistency in frame rates at whatever speed you choose. One jump of frames , you could miss what you are looking for!
and yes my frames are being droped even at 4x speed and getting worse as you go higher in speed. The problem is much less noticable with 1.3mp camera or anolag. It is quite possibly the fault of the VMS but it would be good to have a guide on average what you can expect with a certain spec PC.
