Is it normal to have dropped frames using madVR with lowest quality settings and a 1080i 25fps input?

The card in question is a Radeon 5450.

Madshi has always stated he wanted the OSD to be as spartan as possible, this info is easy to find as it is, he would have it there already if he thought it useful I think.

It is. I tried de-interlacing with 5450 and guess what? I'm 7750 GDDR5 fanless user now.

Hmm the other card I can try is a GeForce 610. Also very low end but maybe it will work better.

Did a bit of research and tweaking, with the cyberlink powerdvd decoder in HAM mode, I can watch broadcasts in 1080i 25fps with no dropped frames. This is using softcubic 100/dxva scaling/smooth motion off.

I had to tweak the backbuffer queue to only 1 for full screen exclusive mode to work without dropped frames though. Disabling the backbuffer queue altogether caused presentation glitches and setting it to 2 was too much.

Everything else was default settings, which I am pleased about.

In windowed mode, I can't seem to tweak anything to work, but that doesn't really matter as its just a HTPC.

Yes, you can watch it, but you can't get hardware de-interlacing (vector/motion adaptive) with Cyberlink HAM. Try those 1080i25 with Cyberlink DXVA and plain EVR (not EVR CP) to check out the difference. But first make sure you have Vector Adaptive and Auto in CCC/video. You can try EVR CP though with half floating or full floating processing, but as far as I remember it was the same story as with madVR.

Deinterlacing seems to work fine, just isn't reported correctly to madVR osd.

I don't know what kind of deinterlacing it is, but it works.

With HAM,

"Auto-select" = "Force bob" = blending (not even bob)
"Force weave" = weave

HAM decoder sends a 25fps (not 50fps of course) progressive (deinterlaced this way) video stream to madVR, whence "deinterlacing off (says upstream)" in madVR OSD. So it works, but is not good in quality. This is true whatever renderer you use, VMR9, EVR, EVR CP, Haali, madVR etc.

If madVR receives an interlaced video stream, its OSD shows "deinterlacing on (says upstream)" and it leaves video to the driver's deinterlacing algorithm (perhaps vector adaptive; of course there are lots of dropped frames if GPU is not good enough to do both vector adaptive deinterlacing and madVR's scaling algorithms).

I would personally much rather high quality deinterlacing + EVR than pants deinterlacing + MadVR. Of course high quality deinterlacing + MadVR is the best.

I see!! What kind of software deinterlacing can I use with madVR then? I guess I'll have to fiddle around with more decoders. I actually prefer yadif to the hardware deinterlacing on my other pc, but this one's cpu can't cut it.

It's at times like this that I wish I forked out for a better card

Does anyone know if there's any media centre software that can use MadVR for everything including TV?

I'm worried MediaPortal's EVR might not be good enough on a good TV, mainly due to banding. I've been doing some testing on my PC (with a monitor capable of passing banding tests very well) and even if there is no expansion from 16-235 to 0-255, there's still a bit of banding on demanding gradients (mainly sky blue). Nowhere near as bad as when expansion to 0-255 is used but still worse than I get with MadVR (presumably due to high-bit-depth internal processing).

I don't know if there are any that support it natively, but what I personally do is use XBMC which can launch any external player which supports madvr. I guess TV would be more complicated like that though.

Yeah MediaPortal can do this too but, like XBMC, it doesn't work for TV. I think the reasoning is that the whole TV/EPG/recordings/OSD interface is built in to MediaPortal and can't be generated using MadVR (right now at least).

For live TV you can use MPC-HC, of course without PVR capability.

Next PVR works too, but it has a bug with program info always showing at the bottom, specifically with madVR , also sometimes it doesn't go full screen.

@madshi: I was wondering, what does Jinc3AR need the most in your opinion? ROP/shader performance or memory bandwidth? It's all discussed in this review, and these days regular 650Ti's are pretty much given away(95€ shipped). Surely the 2GB 650Ti Boost(160€) kills the regular 1GB 650Ti but they didn't dare releasing its 1GB counterpart yet....so it's basically a slightly slower 660(170€) and resellers have to ditch their regular 650Ti's ASAP before they get obsolete.

In shader-heavy games, the vanilla 650Ti is a screaming bargain I think....and I believe Jinc3AR is all about shaders

If all Jinc3AR cares for is memory bandwidth then it'll be a waste of money, though....tough call

I'm asking this here because I made a search but I never got any complete answer from it. What exactly the option "don't use linear light for smooth motion frame blending" do? What I know is that when I enable it, I get a lot of dropped frames. Does it increase quality of smooth motion or something along those lines?

I think so too, afair 1080p24@720p (Jinc3 AR chroma, C-R AR LL luma) even worked with my Intel HD 3000 (OCed to 2.2 Ghz).
Haswell IGP with OC could be nice.

doing it in rbg is simple the correct way to do it that's all so quality is a little bit better

I'm sorry... could you elaborate on that?
