I'm still getting horrible color ghosting and green bar at bottom when switching to 24HZ rate. Does not matter if I use MadVR or MPC-HC to do the rate change. The common denominator for this issue is the video renderer. This does not happen when I use another renderer such as FFDshow. Does anyone else have this problem using MadVR and MPC-HC?

PCs cannot work with analog signals of any kind, the first thing they do when getting one is converting it to digital.
If you have HDMI, you should not use the AC3 encoding in ReClock, keeping the PCM and sending that over HDMI is *far* better. You only need to AC3 encode if you're using a old-school SPDIF connection, optical or coaxial, and want 5.1, because those are limited to stereo for PCM.

I guess my definition of "PC" was a little broader, to include whatever's in the box.
There are older HDMI cards with only SPDIF-like output though, like the ATI 2000 and 3000, and some Nvidia cards from that time which had the ability to piggyback an existing SPDIF output on the HDMI signal. |

unless i am wrong though unless you use ac3 encode you will not get reclock to do its magic as it has to have a decoded audio to work with. it can then send it out over spdif or hdmi. using 'passthrough' for audio meens it cant do this |

Just output the uncompressed audio, and reclock can still do its magic. AC3 encoding should *only* be used if you're either using a real SPDIF connection, or a very old HDMI connection.
Any modern HDMI connection can output 8 channel uncompressed PCM, no need for AC3 encoding it, which greatly reduces its quality.

MadShi: i got a homemade 2:35:1 masking system and i use it on the lower part of my 16:9 screen and i would really like to see your seekbar to stay inside of the movie even when i resize 2:35:1 to 16:9 (ffdshow move blackbar to the lower part of the screen) would this be possible?? it would really mean alot to me

I don't think any of the common decoders are capable of decoding high-bit-depth content yet (and outputting it without converting it down to 8bit)

Hi Madshi could you add hermite scaling (i.e. bicubic with b and c at 0, something like this http://svn.int64.org/viewvc/int64/re...c/kernels.html) to the scaling option of madvr please?
And thank you very much for creating the best renderer there is |

That said, there doesn't seem to be any measure of aliasing, and sharpness is very low. After testing all the scaling algorithms, I settled on SoftCubic 50 because it produced the smoothest, most CRT-like result with images, avoiding a lot of the aliasing and ringing introduced by other filters. Catmull-Rom looks fairly decent on your graphs: no blurring, moderate sharpness and ringing, but there is far too much aliasing when watching video. Oh and there is a great example of why scaling should be done in linear light here: http://forum.doom9.org/showpost.php?...92&postcount=1 (found it when trying to find more on that scaling) I don't believe madVR has this implemented yet, as Madshi didn't see the benefit of it if I remember correctly. I could be wrong though, my memory is awful. Last edited by 6233638; 2nd June 2011 at 02:13. |
