Corrupted motion videos in alerts and stored folders

Hi everyone In the past few months I have been noticing periodic issues on both BI ios ap and confirmed on the desktop of alerts and stored videos, wherein i can see the screen shot but when i play them, initially the video comes blank or if it plays, the part that is moving like a car gets corrupted (pixelated, transparent ) and often skips a few seconds or so. I first saw this on the ios app but on playing the exact same alert on the desktop pc that runs BI alone (i looked directly in the pc), found the exact same thing. I went to my drive where the stored folder is and opened the same time from the .BVR file. The same error and skipping occurs. Interestingly, i tried saving/extracting the video part where there was corruption from BI. When extracting videos, in the window i noticed there are some options. The default mp4 has "reencode to H.264 etc" checked. When i save mp4 with the default, i get the corruption. However when i uncheck it, and save video, the video is clean. However note I am recording on all 6 cams direct to disk. I have attached a couple of screen shots from videos. The first shows the corruption in the car. The second doesnt (unchecked option for reencode to h.264 during extraction). BTW in the ipcamtalk BI thread on Blue iris video tutorials @Dasstrum on this very forum, on video 2 which is for saving videos, the OP shows the check box on. In any case, this problem is intermittent and not for all videos. It sometimes affects one camera and other times another. Does not happen with every alert or saved video. My setup: 6 dahua starlights ipc-hdw5231r-z fed into a switch. PC: i7-6700, 8 gb ram (dell optiplex recommended in these forums) for BI alone Win 10 pro. CPU useage is around 11-15% (have nothing else running..win defender running but no other av product). OS drive is an SSD, Data recorded to 4 tb purple WD BI, recording direct to disk Also there is absolutely no corruption playing videos live on both the pc and ios app. Similarly i can directly log into cameras using NACL plug in and no problems in video. Cameras have been prevented from start from connecting to internet. I have been scratching my head. It looks like some compression or video processing error but my cameras are recording direct to disk. I have updated to latest versions of BI desktop 4.6.6.1 x 64 and ios app. Also i never had this problem the first 6-8 months where i ran the same 6 cams and BI. I presume there have been many updates in the desktop OS, BI, BI ios app so any of them could have messed up. I added a hard drive tester (HD sentinel) and as of now, dont see any SMART error in the hard drives either. Thanks for reading and responding to this long message
