which video renderer and decoder should i use?

[Sameh]

I have GPU Nvidia GT220 / CPU Intel Core i3 / Samsung LCD 23 FullHD 1080p / RAM 4GB DDR3.

the problem:
1080p movies are little choppy/lagging. I don't know what is this problem I think users call it 'Choppy video playback'
but I can say what's exactly happens when I watch HD movies. While the camera is moving and the actor is running or moving, the picture becomes laggy (not smooth).
I tried VLC, KMplayer and Potplayer and the issue happens with them all.

how can i make make movies run smoothly and high quality?
which video renderer and video codec or decoder should i use to get to the high quality and get rid of choppy play.

Open the task manager, play the movie and see if the performance->cpu usage reaches 100%?

Are you using a monitor? or connected to a TV?

[Sameh]

CPU Usage is 15 to 20 while playing movies, it's digital monitor

[Baldrick]

Try also MPCHC.

same problem with mpc-hc ..

Maybe it is because of mismatch between video fps and screen refresh rate. Install madVR and try it with Smooth Motion enabled (should be enabled by default). You can check that with CTRL + J while movie is running.

Try smplayer, go into preferences->performance, set the local file stream cache to 8192Kb. I find this makes an enormous difference. VLC used to have cache settings, why they stopped I don't know.

quality improved.. but still lag..
is my problem called Tearing?

[Detmek]

Tearing is when picture splits horizontaly, so no. When you press CTRL + J does madVR reports increasing count of dropped of delayed frames over time?

yes it's increasing.

Could be that you GT220 is a bit slow for madVR, or for your madVR settings. You can check that with GPU-Z. Download and run GPU-Z while you play your file. It will show you GPU utilization. You may also want to post screenshot that contains madVR statistics (after playing file for 10-20 seconds) so we can see where where the problem is. Something like this:

Thanks man for your help

[Detmek]

Backbuffer queue is empty. If you did not take this screenshot when video playback was paused, that is the reason for choppy playback. GPU is not weak, 21% load so that is not a problem. Rendering time of 21,71ms confirms that.
Two questions:
1. What is your OS and playback setup (player, decoder, version)?
2 Why is your decoder decodes in YUY2 mod? It should be NV12 for 4:2:0 8bit video.
Posible solutions:
1. In madVR settings (accesible during video playback) under rendering - general activate automatic full screen exclusive mod
2. increase backbuffer for windowed and full screen exclusive mode to 6 or 8 and upload queue to 10-12.

[Sameh]

I took screenshot while the video is playing, and i tried solutions and i noticed improvement in the playback. i don't know why it uses YUY2!
I have Win7 x64, Player: Potplayer 1.5 (32bit) ... More at screenshots

[Detmek]

Ah, that's PotP's internal transformation. Anyway, check madVR's stats to see if you still have empty backbuffer and dropped frames. Perhaps some little tweaks of GPU flushes will be needed if you still have problems.

i found this topic yesterday
http://www.reddit.com/r/software/comments/1kzz1q/mpcbe_with_madvr_better_upscaling_quality_than/
so i tested mpc-be today. and i really liked it. mpc-be's backbuffer is 7, dropped frames is too low and stable. and choppy problem gone, everything is now great.. now i'm using mpc-be
thank you very much Detmek.
little question. the backbuffer appears only in window mode and it disappears from stats when i switch to full screen! is that normal? and what happens if i increased the values of queue?

[Sameh]

the backbuffer in windowed mode is good
but the 'Present queue' is full screen mode is 1-8 and sometimes 0-8

[hello_hello]

Try smplayer, go into preferences->performance, set the local file stream cache to 8192Kb. I find this makes an enormous difference.

Placebo? How does a larger hard drive cache make a difference?

VLC used to have cache settings, why they stopped I don't know.

I must have pointed it out a dozen times by now..... they didn't.
Did you notice performance drop after you thought the settings had been removed?

[Detmek]

the backbuffer in windowed mode is good
but the 'Present queue' is full screen mode is 1-8 and sometimes 0-8

So, it should be stable in windowed mode. There is no increasing of dropped or delayed frames?

Yes, it is normal for backbuffer do disapire in FSE when you use "new rendering path" (present several frames in advance).

Increasing queue values keeps more decoded frames in memory. Thus, it uses more memory. If you have slower computer it will slow down seeking as more frames need to be decoded when you jump to some frame. But, in theory and sometimes in practice larger queue improves stability of playback.

About guide you linked and my last statement. When it comes to setting up madVR (and most other software) there is no "one size fits all". You need to set up player and madVR in the way it will work stable on your computer. Just because something works on mine PC it doesn't mean it will work as good as on your PC. So, you need to find optimal settings for your PC and good guide should only present you a tips where to look for and explain some options.

okay.. now the problem completely solved. i think madvr's smooth motion wasn't running well for me, so i tried SmoothVideo Project and really i has a very great result, first i tried SVP with Madvr and i found no increasing of dropped or delayed frames but (high GPU usage). so i switched to Default Renderer (this one works well) . now i'm using SVP with the default renderer. 1080p movies now running smoothly with great quality (no more choppy). Problem Solved
i'd like to thank everyone who helped me in this great forum, and special thanks to Detmek... thanks man
