How do I get really smooth playback? (2 Viewers)

[Jaro Meheš Jr.]

Hello,

I noticed some small jitters when watching 1080p h.264 videos on my system. Tried several codecs, including CoreAVC, Windows 7's default, FFDshow with no change. I also turned on the Dynamic Refresh Rate feature in Mediaportal Configuration, didnt't help either.

I'd like the playback to be as smooth as a BluRay movie, so that all of the movie's frames are displayed for equally long time.

My system specs are following:

3,0 Ghz Core i5
nVidia GTS 450
2 monitors, 1 TV (DVI+HDMI+HDMI)

Strange is though, the jitters are more pronounced when played on the TV.(It's a Sony Full HD Bravia.

Any idea how to get it running smooth?

thanks

Hi there,

It could be several things - logs would help a lot

Just to be sure, you are talking about MP2 (only in alpha) here?

No sir, I'm using the latest stable release (1.2.3).
By the way, the 1.3 alpha is the one referred to as "MP2", or are there any other (even later) versions?

Hi there,

1.2.3 is the current stable version
1.3.0 is currently in Alpha (but based up on the well established MP 1.2.3 version)

MP2 (currently in Alpha) is a completely new version written from the ground up that will succeed Mediaportal 1.x.x

I think Sprag got confused here

Hi Jaro

I know some nvidia drivers were behaving badly regarding video, some people over at the nvidia forums stated that pre 250.xx drivers were fine, but after that jitter was introduced, cannot confirm myself as only even older drivers work for me.

Also try turning Aero off if using Win7, some people have experienced good results doing that, even though its not recommended.

also ,please post screenshot of EVR graph/info (it can be switched on/off with hotkey "!" = Shift + 1) to get idea if EVR sees dropped frames or smth bad happens after it sends picture to video driver...

I'm sorry for posting in the wrong forum, thought 1.2.3 is referred to as 2. Feel free to move this topic to the right section, I'll find it. I'll post the logs and EVR as I get home. Also I'll give MP2 a try.

Hello Jaro, the Wiki Stuttering Playback should give you some hints on how to improve playback quality

Nope, was in mp2 forum section... Fixed now, tho...

Personally, playback wo Aero sucks here.... Due to logmein I had a really hard time enabeling it... Make sure it is enabled for you.
