I'm not so sure, deinterlacing + high fps eat up lots of shaderpower.
I'm rather sure that it's too slow.

You think the j river guys could add support for it in their subtitles?

They already use another interface for subtitle drawing, so from a quality perspective, there shouldn't be a difference, imho.

I just looked in the xy-filter git and the developer is working on it since yesterday.

Does playback work fast enough if you start playback with video deinterlacing + 59, without first switching over from 23 film mode? In other words: Does the issue only occur if you toggle deinterlacing modes? Or does playback always stutter when using DXVA deinterlacing with that specific video file? And what happens if you switch to bilinear scaling, just as a test?

Yeah, they're using the madVR OSD interface for drawing subtitles. This way in theory they can also do high-res subtitle rendering. I don't really know how good their subtitle rendering quality is, though. Never tested it myself yet. Using the OSD interface for subtitle drawing is quite possible, but it doesn't allow frame-exact synchronization. The new subtitle interface has a number of advantages for subtitle rendering. Don't know if J. River will switch to that, though.

Nice!

Alright thanks guys. I haven't had any issues with their sub rendering. Was simply curious if this new interface provided for a potentially better experience.

Potentially better for animated/timing critical subs, but since all i watch is usually PGS subs on Blu-rays or the occasional SRT sub in a MKV Rip, it seemed perfectly fine for me. High quality, too. Not sure its worth the effort to change it, sure wouldn't for me.

Thanks. Like I said I hadn't noticed any issue either. It was more just a curiosity thing to see if there was a benefit. I mean hell they give us hd dvd sub rendering. Gotta love that!

Switched to bilinear scaling.
Start playing in Film mode.
Switching 23 (F)->59 (V), triggers DTS HD MA audio stuttering.
Only Windows reload can cure that stuttering

Ok. You didn't answer my question, though.

Bug report when playing DVDs:

DVD playback started on one screen (FBI warning shows up, etc.). Then the MPC window is dragged to screen 2 and the hotkey I have set to go to the root menu doesn't work. It says "Paused" in the player and basically the only thing that I can do is manually switch titles.

madshi · 4th November 2012, 17:35

Can you perfectly reproduce this problem? Does it only occur when using madVR and not with any other renderer?

dukey · 4th November 2012, 17:35

What was required to stop the macrovision errors with encrypted discs ?

dansrfe · 4th November 2012, 17:45

Actually this problem only happens with one of my discs. I've only checked with madVR, MPC-HC, LAV Filters though.

Nothing special, just use a recent version of madVR, and a decoder which doesn't use a second output pin (ie. LAV Video or ffdshow will do)

dukey · 4th November 2012, 18:07

I see,
I was just wondering because I wrote an opengl renderer some time ago and uncounted the same problem which I couldn't solve.

FFDshow does the same with regards to DVD output, just 1 pin. It has a few bugs in it though sadly.

dansrfe · 4th November 2012, 18:10

I know that this isn't completely on topic but does anyone have recommendations for which calibration tool to buy based on experience. I was going to buy one of the Spyders based on Amazon reviews but I'm not sure which one would work the best. Thanks!

Oh you meant from a programming perspective.
Maybe madshi feels like sharing the details.

Sorry!
If chroma upsampling method is Jinc 3 AR, madvr drops frames doing video interlacing (1080i59 source, ATI 5750).

I really like the Xrite i1Display Pro. It has much better performance in low light and is much faster than the Spyder. I replaced a Spyder 3 and have been very impressed by the i1. If you are still looking for information Xrite's naming conventions are a bit odd, this is the "i1 Display 3", the "i1 Pro" is different.

Both the i1 and Spyder 4 work in HCFR which is what I use to find the values to plug into MadVR.
