News - madVR v0.86.0 Frees HTPC Users from 3:2 Pulldown Judder

Using a HTPC isn't always the easiest way to watch content, but nothing combines the flexibility, capability and potential into a single consumption point like it does. Those that demand the highest quality often rail against the complexity required, and to be fair they have a point, but it's there and few products demonstrate this like the high quality video renderer madVR. As an HTPC advocate, I love it when new features arrive and it's even better when they are exclusive Smile.

For the techincally challenged it can be a little challenging to get madVR installed and configured, so if you fall into this group you may want to wait until the next JMC build to incorportate madVR's newest feature:

Introducing the new "smooth motion" frame rate changer (FRC) with the following main features / benefits:
(1) Can convert any source frame rate to any display refresh rate, while maintaining smooth motion.
(2) Endless playback without frame drops/repeats (if your PC is fast enough) without needing Reclock.


Technically the FRC algorithm simulates a display with infinite refresh rate. Which means that every video frame is displayed exactly when the timestamps ask for it. Consequently the motion smoothness depends on proper timestamps. If the timestamps (or audio clock) contain jitter, the playback will contain jitter, too. So even if Reclock might not be needed to avoid frame drops/repeats, anymore, when using madVR's new FRC algorithm, you might still want to use Reclock, because it provides a stable and reliable audio clock with very low jitter, and it supports WSAPI exclusive mode, too. You can however slave Reclock to the audio hardware clock, if you want. Having Reclock fully enabled with audio resampling is still possible, though, it shouldn't harm madVR's FRC algorithm.

To my best knowledge madVR is now the only way to playback Blu-Ray/DVD movies without 3:2 pulldown judder on displays which don't support 23.976Hz playback properly. I don't think any hardware Blu-Ray player can do that, or even any of the expensive video processors. (Correct me if I'm wrong).

Otherwise grab the latest release and have at it. I know I will (with MPC-HC) later tonight; and for those who are asking (I did) - it should run well on HD4000 GPUs.
