Anyway, 23.971 Hz. Is the current output resolution for sources rip BluRay.
With custom resolutions I get 23.97589 which is quite close to the ideal 23.97602, we're talking about a 0.000005% difference, if I'm not mistaken... Slightly less than one frame repeated/missed (never understood the logic behind this choice) every two hours.
I use Reclock too and never get missed or repeated frames.

I also use Reclock for movie to 23,976fps , I always output that is around 23.971, can publish screenschot with custom resolutions GPU..

RE: Kodi DSPlayer – DirectShow Player for Windows - spencerjford - 2016-05-16

if you can, you'd rather be a bit OVER the speed of the video than a bit under it. Being under it will cause more issues than just over it, even if being under it is closer to the speed you want. This is something I have noticed while using madVR over the years. And this is the case with AMD or nVidia.

RE: Kodi DSPlayer – DirectShow Player for Windows - Talguy - 2016-05-16

So quick question about zooming. Does Madvr have a zoom feature that will display 2.35 content as 16:9 content? Or do I need to use the built in Kodi zoom functions?

What would everyone suggest be the best method/option setting for zooming 2.35 content to a 16:9 screen?

RE: Kodi DSPlayer – DirectShow Player for Windows - Uoppi - 2016-05-16

Talguy, I've never used madVR's zoom for that specific purpose because I prefer to maintain the aspect ratio but madVR's zoom settings have an option to detect and zoom black bars away completely (named "If big black bars are detected" or something like that).

For what I use madVR's zoom functionality, I can say it's quite versatile and works well. I haven't needed to touch Kodi's zoom.

RE: Kodi DSPlayer – DirectShow Player for Windows - Talguy - 2016-05-16

@Uoppi, I'll check it out. I thought the zooming feature was for videos that had the black bars encoded into each frame making the video player think that the video was a 16:9 format not 2.35.

Also, FYI 0.68.1 LAV filters was released. Anyway we can get a new build of DSPlayer with the updated internal LAV filters?

RE: Kodi DSPlayer – DirectShow Player for Windows - nebrunner - 2016-05-16

I use the standard Kodi and player and output 24p content at the native rate to my JVC projector. This has always worked fine for me up until last week when it suddenly started running everything at a very low framerate. I do have a thread going in support with error logs and all of that but it likely won't be resolved soon so I thought I'd try to get a workaround going myself.

Some of the threads I read sent me over this way. Do you think trying out DSPlayer would have a shot at resolving my stock Kodi playback issue?

zoom control can remove black bars and zoom them away. You will cut-off some of the image on a 16:9 screen, of course. It is meant for constant image height projection, where the screen is extra-wide.

Check the setup guide for more detail. You want the settings for Big Black Bars.

You could try display mode switching with madVR. There is a DSPlayer/madVR guide linked in my signature. Be prepared to spend a lot of time reading; it is not a simple process to switch over. I would start by turning off refresh rate switching in Kodi and using madVR's "display modes."

If that works, continue on with the remaining set up.

Thanks for the input.

Ok so I just tested out zoom control against the movie The Martian. This movie is encoded with the black bars from the studio so that the picture is reported to the player as 16:9. Kodi's standard zooming features can not handle this at all since the reportyed aspect ratio matches my display. I did as warner306 suggested and used Madvr's zoom control with the Big Black bars option checked. Worked like a charm without any noticeably weird stretching of the overall picture. Also felt like a lot of the picture wasn't missing which was nice. However I won't be able to daily this option as it increased my rendering time by +40ms. Maybe I'll wait till a pascal card is available to purchase before I try to use this option all the time. Or say screw it and just by a cineascope screen and projector set cause we all know that will probably happen in the future

thanks i will check it out. is it possible to install all of this to a different folder so i can maintain my main kodi install in case i mess up?

You can install DSPlayer as a portable installation.

Watch the instructions:
  • Install to a drive with write permission.
  • You don't need any Start Menu shortcuts.
  • Make sure you don't uninstall your previous Kodi installation when prompted to uninstall other versions.
Kodi Portable Mode

What? Do you have a source for this, an explanation? My point of reference is the original speed of the video I'm playing back. Why should I take anything else as reference? I don't get it.
Unless you are talking about playback without Reclock, which I'm not interested in.

Quote:What? Do you have a source for this, an explanation?
There are two clocks running independently - the video clock and the audio clock. Reference clock is the audio clock. If both clocks are in sync (could be by accident but is normally not the case), perfect refresh rate would be a multiple of the frame rate. So for non-europe movies (24 / 1.001) * n Hz e.g (24 / 1.001) * 2 Hz = 47.95204795 Hz. For the real situation of non-sync clocks things change.
I take my computer as example. Madvr shows the clock deviation between the audio clock and the video clock (this is not changeable!). The value stabilizes after a 15 minutes playback of a movie (it takes some time due to the measurement method). In my case I have a clock deviation of -0.0026%, that´s -26ppm (parts per million) meaning the video clock is running 0.0026 % too slow in regards to the audio = reference clock. That means: In order to not have dropped or repated frames I have NOT to use the refresh rate of 47.95204795 Hz from above but a refresh rate of (1 - 0.0026%) * 47.95204795 Hz = 47.9508012Hz.
The factor is for all different framerates the same, so for e.g 29,97fps: 29,97 * (1 - 0.0026 %) * 2 = 59.93844156 Hz.
With CRU utility one can define custom resolutions to get VERY close to these calculated refresh rates.
In my case I have refresh rates for 23.976 / 24.000 / 25.000 / 29.970 fps movies exactly enough to have no single frame drop or repeat within 3 hours.

Quote:so you should try to get the clock deviation in madVR as low as possible without aiming at 24000/1001.
Surely you meant the right thing but used the wrong term. You can´t change the clock deviation, but you can change the video refresh rate in order to compensate for the clock deviation, see above.

when using reclock. why are you wasting your time changing the video clock?

if you want reclock to change the audio as little as possible you have to match the audio clock.
you are currently just changing a number which could be anything. because no one knows which clock in a PC system is more accurate.
