Is this Avermedia 4K device pci express?it works very well, I also bought the Avermedia 4K and maybe it works even better .. the videos in hdr are treated in tone mapping by the avermedia hardware and are not managed by madVR .. I can't understand how to get the signal in hdr raw without tone mapping and then let madVR handle it. However, the result is exceptional because madVR manages everything else very well ..
Just picked up a 4K60 S+ and am working on setting this up with a re-purposed gaming PC today. (Technically I got it working yesterday- and it looks great- but I need to bypass HDCP from my Yamaha receiver, and I'm getting some dropped frames and presentation glitches in PotPlayer so I'm trying to resolve those as well.)
Pretty sure this would be a big deal if it all works. How are you handling audio?Tone mapping is not done direct from the Elgato card- it can pass through HDR information over USB 3.0, and is then processed by MadVR in PotPlayer. Tested and confirmed- just trying to eliminate some glitches.
Great test video is the LG Jazz video- gorgeous colors after tonemapping, almost makes the vanilla version look lifeless. Chain is currently NVIDIA Shield Pro -> file on my Plex server -> Plex -> HDMI out -> 4K60 S+ -> PC -> Projector.
Currently the audio is going into my AVR with the video, but the 4K60 S+ doesn't pass through Atmos/TrueHD, so my end pipeline is going to be AVR HDMI1 Out -> Projector HDMI 1 (don't need the game consoles to have latency introduced), and AVR HDMI 2 Out -> HDCP stripper (4K60 S+ doesn't have an HDCP handshake and the Yamaha AVR forces a handshake, so... stripping time!) -> 4K 60 S+ -> PC/MadVR -> Projector HDMI 2.Pretty sure this would be a big deal if it all works. How are you handling audio?
Just to update here: the 4K 60 S+ works great but the audio is so far ahead of the video that even far off lipsync offsets are difficult (and, I think, can vary depending on the latency of what you're processing). You can even see on Amazon where Elgato calls it out- the 4K60 S+ has a latency of 250ms to display in software (passthrough should be instant).
I'm running another test over the next few days: I'm going to cobble together an HTPC with the PCIe variant of the card (4K60 Mk. 2) that should have no input latency (well, it's always there, hopefully it's just minimal single-digit millisecond latency), and as long as MadVR is still processing at a good clip (I think at my current settings it was going at ~10ms a frame), I think this should make the audio lipsync much more manageable. We'll see. I do love playing with this stuff.
Unless I'm missing something extraordinarily stupid, I am indeed tonemapping live content coming from the device.
Alright steppi- I even found your thread on Reddit trying to figure out why the Elgato wasn't passing through HDR metadata today- I'm afraid I've ended up at the same conclusion after diving in a bit deeper. (My earlier post about missing something extraordinarily stupid ended up being, in fact, correct: I am stupid!)
I've found only one other capture card that can process 4K HDR @ 60 Hz: the AverMedia here: Amazon.com: AVerMedia Live Gamer 4K - 4Kp60 HDR Capture Card, Ultra-Low Latency for Broadcasting and Recording PS4 Pro and Xbox One X, PCIe Gen2x4 (GC573): Computers & Accessories
Hopefully this one sends metadata through properly.
Blessed be Amazon's return policy.
