| Posted - Nov 26 2020 : 8:26AMDownloaded some videos from 5K Porn (they're 5120*2880 at 60fps, 40Mbps) and found they won't play right on MPC-HC, which I've used flawlessly for years and have configured with MadVR and ReClock. Problem is audio immediately gets desynced from the video. I've tried changing the video and audio renderer but nothing seems to work. Any ideas? [Link] |

What's your PC spec? [Link] |

^ HP desktop -Windows 10 -GeForce GTX 1070 -Intel i7-4930K -16GB RAM. Will probably be upgrading to a Digital Storm Aventum pretty soon with i9-10900K, 3080, and 64GB RAM. My PC is ~11 years old at this point and only thing I've changed is the graphics card.  [Link] |

Nothing there strikes me like it would create an obvious bottleneck. To rule out MPC-HC as the culprit, have you tried playing back through VLC Media Player or Pot Player?It's been a few months since I ceased subscribing to the site but the 5K Porn scenes I got from the site in 2880p had no problems with audio & video sync and my PC spec wasn't hugely dissimilar to yours at the time. What monitor and cable are you using?  [Link] |

VLC is a choppy mess, basically won't play it at all. I don't have Pot but I tried JRiver and it does work on there, but I really dislike using JRiver for video because of the lack of controls (it's unbeatable for audio, though). Monitor is just my 75" Vizio TV, cabling is all HDMI. Weird thing is that JRiver also uses MadVR so I can definitely rule that out as a problem. [Link] |

If another software works then it's not hardware or video. Did you update the software? can you contact the dev with the video/your comp. specs and see what they say. [Link] |

^ Yeah, it's definitely a problem with MPC-HC, or at least how I've got it set up. MPC-HC hasn't been in further development for over 3 years now, but it's still the best, most customizable player I've found. Until these videos it's also always worked with everything. [Link] |

Your GPU can't handle the 5K file unless it's HEVC and your PC is otherwise too outdated to be of use, as it's packing a low amount of ancient DDR3, which is going to be a big bottleneck for you. The 4K version of the file should play relatively smoothly on your hardware. If you wanted to blow a little money, you could certainly upgrade the RAM to a full 64GB, but you'd still need to throw in an SSD or two for reading video files from. If I had the model number, I could give you a more concise answer, though you will certainly be better off with a new PC. JRiver is likely using different decoding settings that manage to work better than VLC or MPC-HC, so you should check the settings.Edited by - LetTheWookieWin1981 on 11/30/2020 7:00:01 PM  [Link] |

^ How about trying to offer some help without imparting misinformation and hyperbole as fact?I have the same GPU and I played 5K Porn's 2880p videos without any trouble so I think we can dispel any notion that the GTX 1070 "can't handle the file". On top of that, the OP said they were able to get JRiver to work though it's not to their liking in controls. The CPU is still good by today's standards and will even give today's Core i5 processors a run for their money so they are capable of preparing 5K video frames. DDR3 may be older but it is still usable, particularly with overclocking if that's feasible. Enabling hardware acceleration can also help make the most of somewhat older computers. 64GB RAM is overkill for system memory when it comes to 5K video playback. For 8K video editing with multiple video streams, sure, but 5K playback will run fine on 32GB or "just" 16GB if your GPU has decent VRAM and you have a quick CPU. The OP may be upgrading their hardware soon but for the benefit of those who don't have that luxury, writing off older computer hardware as "ancient" isn't the best advice I've seen when it's beyond reasonable dispute that just because hardware is older, it doesn't always mean it can't get the job done.

^^ I'd also add that, at least for video, JRiver is running the same decoder settings (MadVR) as MPC-HC, which makes the whole thing even stranger. This is probably moot since I do plan on getting a new PC soon. [Link] |

I actually found the problem. It wasn't working on the 32-bit version of MPC-HC but would on the 64-bit version. Problem with the 64-bit version of MPC-HC is it's incompatible with ReClock, which means stuttery playback when I try to fast-forward through certain parts of scenes, which is why I've stuck with the 32-bit version. Guess I can just have both and only use the 64-bit version for 5K stuff. [Link] |
