What's with the 'Video Scaling Method' / 'High Quality Software Upscaling' thingy?

Hitcher · 2008-10-21 18:18

I've noticed the difference when I select 'Bilinear' (looks better) but I now have a problem with 'Set as default for all movies' not saving and reverting back to 'Nearest Neighbour' all the time.

Is it any of these options in the guisettings.xml -

PHP Code:

<videoplayer>
        <calibrate></calibrate>
        <displayresolution>10</displayresolution>
        <dvdautomenu>true</dvdautomenu>
        <dvdplayerregion>0</dvdplayerregion>
        <editdecision>false</editdecision>
        <highqualityupscaling>1</highqualityupscaling>
        <jumptoaudiohardware></jumptoaudiohardware>
        <jumptocache></jumptocache>
        <rendermethod>2</rendermethod>
        <sep1></sep1>
        <sep1></sep1>
        <sep2></sep2>
        <sep3></sep3>
        <upscalingalgorithm>8</upscalingalgorithm>
    </videoplayer>

Figured it out.

It was saving the 'Bilinear' Video Scaling Method in the video OSD but that gets overridden by the High Quality Software Upscaling settings in the Video options, which I had set for SD material.

It's all a bit confusing.

I'm having the same problem, are the two settings the same? If i turn off high quality software upscaling will it still upscale my videos with the setting in the OSD?

High Quality Software Upscaling will override the OSD settings.

I have that turned off in video settings. However every time I play a video it's greenish. Now if I enter the OSD the "Interlaced" setting is always set to "Blend". This is the only setting that produces this greenish picture though. When I choose another one the picture's good and it stays good until I close xbmc. The "Interlaced" setting however is not saved so I have to do the same again after a restart.

Using ATI Radeon X1250, Driver 8.561.0.0 (01.12.2008) on Vista Home Premium 32 Bit SP1, and XBMC "pre-9.04 SVN unknown (Compiled: Dec 29 2008) "XBMCSetup-Rev16749-jester.exe". ATI hack is in advancedsettings.xml

I don't know why but all works now. I think all I did was restart windows. All's well now. Interlaced is now set to "Auto" and scaling method is "Bilinear". Render method is set to "Auto". Upscaling is turned off. Vsync is off in xbmc and set to always on in catalyst. Perfect video quality. Laugh

Don't know if it's related but cpu usage dropped significantly as well. It's now around 3-10% when playing videos (regardless which videos I play, dvds or avis)

Shouldn't you have XBMC set to "let driver decide" for vsync?

Also, what do the various Render Methods actually do?

ie Advanced Shaders (GLSL), Basic Render (ARB).

Honestly, I don't know what I should have. It was pure try and error until I got it done.

I also don't know what the various Render Methods actually do.
