I would use Lanczos3 + AR or Jinc + AR for the upscaling profile. Bicubic150 is sharp, but it will produce ringing artifacts at that strength and a worse result than the other two.

Same goes for chroma upscaling. I would use Bicubic60 + AR rather than Bicubic150. Ringing artifacts can be even worse when applied to the chroma.

NGU high is a good choice for image doubling. No need to max out that setting at the expense of an overly low-quality setting for chroma upscaling. Your projector can display 4:4:4 chroma, so it isn't a complete waste to use a reasonable setting for chroma upscaling.

I'm not sure if I totally understand the scaling steps with an anamorphic lens. Besides the anamorphic stretch checkbox, what settings in zoom control have to be enabled to get the correct aspect ratio for 16:9 movies? Do you still get the black bars on the sides?

Thanks. For the anamorphic lens settings, I just need the following:
1) black bar detection on
2) crop black bars (so most 1080p material is being scaled from 1920x800 after cropping up to 4096x2160, using 4x NGU sharp and then downscaling from there)
3) anamorphic stretch on, with (for my lens) a 5/4 ratio

Ok I got it. I realize I didn't understand screen masking and the different options for output resolutions for scope screens. So you get the best results with more pixels from the GPU.

Then when the player exits, my restore script runs:
Code:

		If $hFile <> -1 Then
			Local $RunRestoreCommand = FileRead($hFile);
			FileClose($hFile);

			RunWait($RunRestoreCommand); PMBR is for brightness, then 0000 is 0, 0001 1 etc
                EndIf

c:\htpc\JvcControl.exe RawRead:PMGC saves gamma value to file JvcReturnValue.txt
c:\htpc\JvcControl.exe Raw:PMGC06 sets gamma correction to 1.9

Most the raw codes in the manual can return a read value if you leave off the last nibble that sets it and pass RAWREAD instead of RAW. I'll go make sure jvccontrol is updated on my site to support this.

@markmon1 is there any other way except the text file to get the output of the RAWREAD command?

Just trying to see if I can get teh current state diretly into a variable instead of reading a file.

No but the text file is an easy way to handle things. What problem are you having? Maybe paste your existing file I can help you rewrite it or convert it to autoit

Thanks for the tips- I ended up going with Lanczos4 + AR for both luma and chroma upscaling for my HDR profile and I'm around 30-35ms rendering. Any reason to drop down to Bicubic60 + AR for chroma instead?

Or Jinc +AR for luma and bicubic60+ AR for chroma?

Or 3 taps instead of 4 for Lanczos? Too many options, @madshi ! &#x1f642; jk

I figured it out :-) Thanks.

Here are the updated batch files. These files use the Raw codes to send to the projector, and I personally found using these to be 'slightly' faster than the codes in the Commandlist. Other benefit / drawback, depending on how you look at it is that sending raw codes does not display any OSD, so lens memory changes are more 'transparent'

To use there are a few configuration variables in each batch file: IP address of the projector, path to the JVCControl.exe, appropriate rawcode to send, etc.

I don't think MPC-HC can take a command line for navigation. You have these options:

1) Convert your bat scripts into autoit or autohotkey scripts and use the send commands in these to send the play / pause keystrokes.
2) Switch your player over to zoom player and use the zplayer.exe /fnPlay and /fnPause commands. Zoom player can accept further commands to an already running instance in this fashion.
3) Create an autoit or autohotkey script to just send the play/pause keystrokes to MPC-HC, but if you're going to do all this you may as well use #1 . Plus, if the command prompt is the foreground task, the standard send function in these will probably just send to the command prompt window so you'd actually need to implement a more complicated windows message to send a keystroke message.

The other benefit of switching to autoit from bat file is that no command prompt window will show up when the script runs.

Also, I have attached the IP / RS232 full command spec for the new NX5/NX7/NX9 series here in case you want a more updated doc

How complex is the conversion to autoit? I may give it a shot, but other than these batch files the last time I programmed anything was C++ more than 25 years ago

Bicubic60 for chroma might save a very small amount of performance and you won't likely notice any difference from Lanczos.

With Lanczos, more taps = sharper image, but increased ringing artifacts.

So for an example, I did a line-by-line conversion (without compiling and testing) of the scope bat script above into autoit. Here it is:
Code:
#include <File.au3>


Local $JCpath = "c:\htpc\"; path to JVC control with \ at end.
Local $ProjectorReadCode = "INML";
Local $ProjectorCode = "1";
Local $ProjectorRawCode = $ProjectorReadCode & $ProjectorCode;
Local $ProjectorIP = "192.168.1.200";

; make sure JvcControl is not running and wait up to 10 secs for it to close
ProcessWaitClose("JvcControl.exe", 10000)

; set raw code for Lens Memory 2

; Log to log.txt
_FileWriteLog($JCpath & "log.txt", "Scope was run");

FileWrite($JCpath & "JvcControlIp.txt", $ProjectorIP);
RunWait('"' & $JCpath & 'JvcControl.exe" rawread:' & $ProjectorReadCode);	
Sleep(2000); upped your clever use of ping as a delay from 1 sec to 2

Local $ProjectorMode = FileRead($JCpath & "JvcReturnValue.txt");
;Grab last character of file.
$ProjectorMode = StringRight($ProjectorMode, 1); 
;Delete the JvcReturnValue since we are done with
FileDelete($JCpath & "JvcReturnValue.txt"); 

If $ProjectorCode <> $ProjectorMode Then
	If ProcessExists("JvcControl.exe") Then
		Sleep(5000);
	EndIf
	RunWait('"' & $JCpath & 'JvcControl.exe" raw:' & $ProjectorRawCode);	
EndIf
Note: I feel a few of these things aren't needed. You don't need to check the lens memory on the JVC you can just switch to it. It has no visible impact if the lens is memory 1 and you switch to memory 1.

Also, I'm still not sure why the check for JvcControl running is needed.

Instructive as always. I will give zoomplayer a shot tonight. Is it as lightweight as MPC-HC?

Also will try to convert these scripts into Auto IT this weekend. I worked in Basic ages ago, so would be fun!

Now that I am on this path of automation, I am wondering what else I can automate. My holy grail would be for me to walk into my theatre and tell Google Home, lets watch say Dunkirk, and then, it turns off the light (which it can do today), turn on the electronics, and start to play the movie.

Were you able to convert those hdr and SDR batch file scripts to autoit?

No, the batch files were working fine - so didnt prioritize that. Decided to watch some movies instead :-)

Will probably get to it this week.

There's a bug with the drivers with some dithering options. I had the some issue, fixed it be changing that.

a little help understanding madvr hdr passthrough?

i was under the impression that if i set madvr to passthrough hdr (madvr > devices > device (lg electronics) > hdr (then check "passthrough hdr to display" and check "send hdr metadata to the display" boxes), i would not have to enable windows 10's hdr toggle in order to get my ripped hdr library files to play in hdr on my hdr tv and hdr projector.... is that the idea behind madvr hdr passthrough or am i misunderstanding its function?

i've tried madvr hdr passthrough using both potplayer and mpc-hc but neither of my hdr displays detects hdr when i play an hdr file (the hdr logo on my tv doesn't display, and my pj's info feature shows sdr)... however with madvr hdr passthrough enabled or disabled, both of my hdr screens display hdr when i turn on windows 10 hdr.

what am i doing wrong?

It is almost always an incompatible video driver. Sometimes checking fullscreen exclusive mode and 10-bits in madVR helps, but sometimes you need to install another video driver that doesn't have any bugs, such as one of the most recent Nvidia drivers.

Be careful with the latest driver though ... I noticed the dreaded stuttering again!

so to be clear, using madvr hdr passthrough should allow me to see hdr with windows 10 hdr turned off?

if so i will definitely play around with drivers, prob is most (all?) driver discussions / success stories / workarounds i've come across seem to involve nvidia drivers, not intel drivers.

funny you should mention that... in windowed mode i get flawlessly smooth playback, but when i switch to fullscreen i get bad stuttering during panning scenes and fast action scenes, despite cpu usage and memory in the low 50s or less, does this also point to a driver prob?

intel doesn't have an HDR API so you have to use the windows API.

madVR is GPU based.

so does that mean i can't get madvr hdr passthrough with my igpu, instead the only way to get hdr out of a windows 10 + igpu box is by enabling windows 10 hdr? no other way to pass the raw metadata to the hdr display?

i see, so looking at cpu and memory usage (in task manager) is meaningless is this case, instead i have to look at the gpu usage stats using the player's info screen? makes sense.

madVR has GPU stats to but they are a little bit harder to interpret because a GPU has multiply part and a high range of clock rates. edit: try GPU-Z but always consider the GPU clock they change a lot on intel.

intel is currently (for the most time) in a bad spot for everything GPU based.
i have no clue if madVR works together with the windows HDR API and gives it the HDR meta data but we know it the microsoft API is doing a really bad job(conversations in the back and stuff liek this) in general for HDR so no wonder AMD and NVIDIA created there own APIs.

intel is very disconnected with there user base.high end iGPU only in high end CPU where most user are using an dGPU anyway if they care about GPU performance
just wasting 20-30% silicon on the CPUs...so don't except them to fix this issue anytime soon.

Hi all,

I'm struggling with Kodi and MPC-BE bc of missing timeline and other features... so I went to JRiver... so far so good.
But the UI and the scraper of JRiver is nothing compared to my beloved Kodi Setup...

I stumbled over a screenshot and was wondering if someone could tell me which player is used there:

Many thanks

That's Kodi DSPlayer, which still works but ended development at Krypton 17.6.
