Smoothing AVI playback ?

[Rory]

Hi
when I play back a PAL XVID avi in Media Player it looks amazing. I know I can't expect the same quality via MVP, but it seems to be significantly worse and I would like to tweak my transcoding to get the best quality. What is messing up playback is not stuttering but a lot of jaggedness (jaggies) on any curves like text. It is especially noticeable in title sequences and big logos. I don't get this on Mpegs created by GBPVR, only on AVIs playing via the MVP. I would like some tips on where to start tweaking or different codecs to try. I am not sure if it is compression artifacts, some sort of deinterlacing artifact (source is not interlaced) or just poor mpeg quality.
My specs:
Athlon XP2400 768MB Ram, MVP, Muxchecker reports Intervideo 3.0.88.0, Cyberlink 5.0.1307 on the playback tab in config everything is at default, PVRX2/GBPVR renderers are VMR9 Custom, I am trying to play back a PAL XVID with AC3, 640 x 272. No FFDShow, No FFMpeg.

The MVP cant play AVI files natively so it has to transcode the files to MPEG2 on the fly. The default settings for this arent super high quality, mainly because I needed a balance of decent looking and the average user machine being able to keep up with this CPU intensive task. Your machine needs to be able to transcode in faster than realtime for this process to work.

If you machine is grunty enough (I dont know if it is) then you can increase the quality (bitrate etc) in the <MVPFFmpegTranscodeCmdLinePAL> or <MVPFFmpegTranscodeCmdLineNTSC> settings in config.xml.

WOW !
I took your cue and adjusted the config.xml. I have a Athlon XP2400 which is 2000 mhz. Rather than adjust the bitrate, i adjusted the resolution.. hey presto, DVD quality on-the-fly ! The difference is chalk and cheese ! And even in high motion scenes, no skipping. For me this is like the holy grail..
Here is the adjusted config.xml

<MVPFFmpegTranscodeCmdLinePAL>-y -i "{SOURCE_FILE}" -b 2400k -ac 2 -ab 128 -r 25 -s 704x576 -f svcd "{DEST_FILE}"</MVPFFmpegTranscodeCmdLinePAL>
<MVPFFmpegTranscodeCmdLineNTSC>-y -i "{SOURCE_FILE}" -b 2400k -ac 2 -ab 128 -r 29.97 -s 704x480 -f svcd "{DEST_FILE}"</MVPFFmpegTranscodeCmdLineNTSC>

thanks sub ! I will watch a few things and let you know if I get any problems !
