PotPlayer audio crackling

[George.J]

File caching: It buffers the file for a certain time, before you start playing to give you smoother playback. The value that was set, was not enough to complete the buffering for a HD video file that has more pixels on screen that regular videos, and thus created stuttering/skipping problems. But there's also a problem if you increase file cache time. 1000ms = 1s buffer time as per your setting. When you seek to a different point in the video it'll take more time, as it'll need to buffer for that much time before continuing to play the video.

VLC: You could also turn on Hardware Accleration in VLC by following this: https://wiki.videolan.org/VLC_GPU_Decoding/
and switch your video output module to Direct3D/OpenGL by going to Preferences->Show All Settings->Video->Output modules, as alternative ways to get video playback smoother.

Media Player: Between PotPlayer and VLC, it's all upto user's preferences. VLC has a good documentation and official forum support for the users. Moreover the settings in VLC have been made easier for novice users, by having two separate windows for "Simple Settings" and "All Settings". VLC works well on low-end and high end systems. If you've a good system, then PotPlayer is a great choice. PotPlayer does play HD videos and Blu Ray (from reports, as I don't have BD yet) smoother, has excellent subtitling capabilities, and is updated constantly to give you the latest codecs & filters and many new features to look forward to. I mostly use the right click context menu to get my preferences, which is easier to navigate. Folks at VideoHelp are also extremely helpful and knowledgeable when you run into problems or have questions about PotPlayer.

Subtitling Question: To sync and save the subtitles permanently why don't you let PotPlayer do it? Right click->Subtitles. It also has sterioscopic 3D subtitle support and capabililties for various subtitles effects.

PotPlayer: I see that you've a high end system, you could turn on Hardware Acceleration in PotPlayer for better playback, by going to Preferences->Filter Control->Video Decoder->Built-In Codec/DXVA settings->Check the box for "USE DXVA" under Hardware acceleration (DXVA) settings. Make sure you're using the latest video drivers. Also if you've installed OpenCodecs during PotPlayer installation, then go to Preferences->Built-in OpenCodec and enable Intel QuickSync or nVidia CUDA decoders (only if needed, and only if you are not enabling DXVA acceleration.). Also try switching your video renderer to Madshi (Right click->Video->Video Renderer). If you're patient you could read this guide to get high quality video playback in PotPlayer, although it's a long read, so I wouldn't recommend to novice users.

I have had issues playing high quality videos like mkv and wmv in Pot and VLC but this persists whether or not I have other codecs installed ... enabling hardware acceleration helps a lot.

I'd be interested to see the results on a clean system when you play videos on PotPlayer or VLC.

I did that when we discussed this problem a while back if you remember, I keep a drive image of a fresh W7 installation which is useful for working through issues like this.

I've tried several different codec packs and I can honestly say that they've all worked well in harmony with players that have their own internal codecs. I realise that other people do have problems with them though, so I appreciate that they aren't for everybody, I'm just saying that I don't think problems are unavoidable... I run a very minimal system with only about half a dozen third-party installations and it probably gets restored to a fresh state about once a month on average, which is perhaps what makes the difference. If you want to use the WMP engine with support for a decent range of formats, then they are needed.

Concerning playback of HD video, the single thing that made the biggest difference for me was enabling hardware acceleration in Pot Player etc, although the smoothest and least resource-demanding playback is still achieved by the WMP engine.

In guide it says that for madVR NNEDI3 image doubling you must have a gtx titan or radeon 290. I have a gtx 760 so is the gtx 760 powerful enough for using image doubling or not? You recommended me to turn on in potplayer Hardware Acceleration what are advantages over software decoding using the cpu?

The same reason why you prefer games to use your external graphics card instead of the integrated one. You get better performance, and you take the load off from the internal GPU. Your video card is somewhere between the low-end and high-end they have given in the guide, but I believe 760 should be enough for image doubling.

Honestly, settings in a media player aren't the universal best for all systems. Which is why you might have stuttering/lag problems in certain ones however good their system might be, compared to others. Tweaking the settings might be needed here, but users prefer the easier route and go for codec packs to do their work. Needless to say, they'll have to bear the risks too, if encountered, because they've the capability to delve deep into the registry and change the values which might not be re-set ever again, even after uninstallation, and we arent talking about a few entries here, when you opt for mega codec packs.

And make sure you've the 32bit version of PotPlayer to use MadVR. It doesn't work on 64bit

Ok.Tnx for help
