  1. Hi Ranpha,

    Thanks again for this blog. I love it. I am getting jittery playback with the latest update. I reinstalled and tried running it without my presets and I get the same jittery playback. I am seeing the file play clearly on VLC. I have an NVIDIA GTX 960 GPU and I have the mid-level MadVR settings from your installer running on PotPlayer at the moment. Thoughts?

    • Pick a video file that you use for a test, then:-
      1. Put the MediaInfo result for the said video file here.
      2. Play the video file, toggle on madVR’s OSD by pressing CTRL-J, wait for several second when the jitter happens then make a screenshot and put them here.

        not sure I am doing mediainfo right or not…

  2. Hello ranpha I was wondering if your latest build includes madVR version v0.90.24?

    I need to test out madshi’s new changes as from version .24, OpenCL kernels will saved separately between 32bit or 64bit.

    Also, for your 64 bit build I’m guessing you’re using the 64bit madVR build correct?

  3. Hello ranpha, thank you for all your work.

    Can you please clarify the main difference between PotPlayer’s Normalize Matrix (like in LAV Filters) and the Normalizer’s (e.g. Tomsteady)?

    Thank you in advance.

            • Oh, I thought you are talking about LAV Audio Decoder’s normalizer first. Then indeed those two works differently.

              The one at ‘Audio —> Normalizer/Freeverb’ section always kicks in to prevent sudden changes in audio levels. There are situations when you watch a TV show on TV, then when the advertisement kicks in, their audio level suddenly go up so that even when you go to the bathroom, you can still hear it. This normalizer takes care of that.

              The normalize matrix at the ‘Audio’ section only kicks in when you do upmixing or downmixing, so that audio levels in all output channels is the same. Surely you don’t want only left speaker has higher volume, while the center one doesn’t?

              • Now I understand, so I assume Normalize Matrix should be always on while Normalizer is optional.

                Should I use LAV Filter’s “Normalize Matrix” or PotPlayers? Does LAV Filter’s “Normalize Matrix” work on Bitstreaming too?

                Also, is the Normalizer’s Tomsteady or Complex Arithmetic considered better?

                • Should I use LAV Filter’s “Normalize Matrix” or PotPlayers? Does LAV Filter’s “Normalize Matrix” work on Bitstreaming too?

                  Use the one in PotPlayer.

                  Also, is the Normalizer’s Tomsteady or Complex Arithmetic considered better?

                  I can’t really say. You probably should experiment.

                  • I understand, thank you for your time once again ranpha. Have you considered having a forum so that top / most common questions are easily visible to everyone?

  4. Hi Ranpha, thanks for the good work. am using potplayer 64bit, video decoder native, with radeon hd 5650 card……with the July 19th update….potplayer crashes when you try to close the player or I queue some videos….other versions were working perfectly. help

    • You have to wait until I update the installer to the new version to see if the problem of your can be solved or not. Unfortunately I do not have time to do this until next week at the earliest.

  5. Is it normal that my gpu makes an attrocious noise (not the fan) with 30% charge only in gpu-z. It sounds like “yiiiiiiiiiiiiiiiiiiiir, yiiiiiiiiiiiiiiiiiiiir, yiiiiiiiiiiiiiiiiiiiir”. Games runs without this kind of noises!
