Couldn't you say the same about MPEG-2 vs H.264? H.264 uses less hard drive but it requires more CPU cycles so let's stick with less sophisticated compression algos.

4MP using H.265 codec

Same here. Just hope they end up working on it sooner than later, as switching it to h.265 for them to test essentially takes it down in terms of its usability for me. :/

See the latest update which seems to have resolved this issue..
Awesome, my five Dahua 5231R-Zs now display video properly in BI (when switched to H.265)!
My system has an older pre-Skylake processor (i7-3770) which doesn't do H.265 hardware acceleration. The CPU hit from turning on H.265 wasn't as bad as I thought. The BI service went from using 10-15% CPU to 25-30% CPU.

Just got around to trying this out.
I switched 1 of my 5321's over to H.265 and no more 1/2 green screen!
I record 24/7 with 1 hr clips and the clip size has been reduced from 1.75-2.0GB, which was typical size day\night with little or no motion triggers) using H.264 to 1GB using H.265 the last couple of hours.
Image quality looks just as good to my eye on my24" monitor.
CPU usage does not seem to have increased at all but I have only switched 1 of the 4 cams over from H.264.
Now I can hold off buying another HDD for a while....

+1 - I switched 6 out of 8 (the ones that are 265 capable) over and it has pretty substantially reduced my disk usage with no material increase in CPU utilization
I'm having trouble with recording direct-to-disk h265. I recently switched from .mp4 recording -- which was working, but having issues -- to BVR, which is now recording blank h265 video files. My cameras that are streaming h264 are recording fine.
I tried converting one of the blank BVR videos to MP4, but it' still blank.
Anyone else having trouble?

there is a thread discussing this..revert back to an older version and email support.
I have a few setups running Dahua cameras with h265 and 1 dahua h265 on my home setup. They are run fine for me however I have noticed that they use a LOT more cpu than similar camera running h264.
On the exact same setup/cpu/frame rate ect... with 4 cameras running h264 I get like 20% cpu usage. If I switch out those camera with the Dahua h265 the cpu usage goes to like 35%.
Is there a setting that I am missing to make h265 more efficient?

I switched my Dahuas back to h264 and now everything is working fine. I'd much rather use h265 as the files are half the size... but I'll live with it.
My CPU usage didn't change noticeably from four cameras running h264/h265 (the h265 encoding is performed camera-side). And as I mentioned, h265 was working in Blue Iris when recording to mp4. I'd assumed that Blue Iris wasn't doing any conversion, and indeed, "direct to disk" would seem to indicate that it isn't converting anything.
I switched to BVR from mp4 because of occasional blank recordings, and because the BVR files seem much snappier when dealing with them inside Blue Iris. Also, it's easy to Export any desired file to mp4 if I want to play with it outside BI.
