Improving video quality?


Recommended Posts

Posted

So I recently made the jump from a 20in 1280 x 1024 monitor to a 32in 1920 x 1080 hi-def TV for my cab.  The switch to widescreen (especially a much larger widescreen) proved to be an unexpected hassle with regards to the graphics, as I was not aware that HS natively ran at 1024 x 768.  Skipping to the point, thanks to Dark's excellent scripts, I've been able to create base themes in 1080p that are graphically crisp, but the video quality is now below average...as in, it got MUCH worse in the upgrade.  I get that scaling up the 640x480 video to be larger would create blurriness.  But I'm running them at their native resolution in the theme (albeit with a 75% width modifier to keep the perspective correct), and they look SIGNIFICANTLY worse (and strangely smaller) than when just playing them in Win media player.  So 3 questions:

1.  Is this all a result of the 75% width correction?  It seems to be a lot blurrier than I would expect if it is that, and the height scaling would not be impacted.

2.  Why is the video physically smaller in the theme?  I'm running it at native resolution (width adjusted).  That makes no sense, unless the video is being scaled down at the same rate as the overall window...  i.e. 1024x768 ----> 1920x1080  (Update to this - the pics below were sampled from a 1366x768 laptop, so there shouldn't be any vertical scaling.  I now have no idea why the two aren't the same height.)

3.  If my guess on question 2 is correct, ss there any way to stop HS from trying to widen the video portion?  (thus removing the need to force the aspect ratio)  Or a way to pre-correct for this (similar to converting the .pngs to .swfs)

Attached are the 2 screen caps of the video from WMP and HS for support, as well as the simple theme I'm using to beta this (no background or artwork).  Any help or insight would be appreciated.

Windows Media Player Version - Unscaled

Theme version - also unscaled, but obviously smaller for reasons unknown.

The theme language:

<Theme>
    <video w="360"
           h="640"
           x="330"
           y="370"
           r="0"
           rx="0"
           ry="0"
           below="yes"
           overlaybelow="false"
           overlayoffsetx="0"
           overlayoffsety="0"
           forceaspect="both"
           time="0.5"
           delay="0"
           bsize="0"
           bsize2="0"
           bsize3="0"
           bcolor="16777215"
           bcolor2=""
           bcolor3=""
           bshape="false"
           type="fade"
           start="none"
           rest="none"/>
</Theme>

Theme.xml

The video dimensions are set in the theme.xml as you can see at the top of the example.

If you are trying to run videos set at a 4:3 ratio in a 16:9 environment having them forced to Both should not let them change with the ratio/resolution.

If you can find the native video dimensions you should be able to set the theme to use those.

However if they are still expanding with the theme to the new ratio you may need to adjust the H and W options to compensate.
