I've used BI for several years and noticed ghosting (pixelation of a moving object in a recording) that occurs more frequently at higher resolutions. My last attempted fix was to switch from .264 to .265 on my 8 MP cams (2CD2085FWD). Looked at half a dozen recordings and no ghosting. Hardware acceleration is disabled in .265 as BI doesn't currently support it. Then I decided to switch back to .264 and turn off hardware acceleration for all cams. No ghosting. Is hardware acceleration to blame for the ghosting issues? Seems like it to me. Hardware I'm using below: Server- 8700k with 16GB RAM using onboard Intel video. Mix of five 4/8 GB hard drives directly connected to the motherboard using Stablebit Drivepool to manage them. 6 Hikvision cams, three 8 MP, two 4MP, and a 3 MP. All running at max resolution and fps. Connection is either through bonded MOCA adapter (80 MB/sec transfer) or WiFi 5GHz bridge to server (link rate 100 MB/sec). Main router sits next to server which is an ASUS GT-AC5300 which receives streams either through WiFi or bonded MOCA adapter. Router is connected to the server with dual 1 GB ethernet using 802.3ad link aggregation. Cam receive buffer at 20 MB, I interval matches FPS. These didn't help ghosting much IMO.
