AVI Transcoding Quality

Gents,

To get AVIs to work with my Panasonic Plasma from Costco, I had to add the following to the PROFILES.XML file:

<Profile id="30" name="Panasonic Viera With AVI Support" extendsProfileId="1">
<ContentDirectoryMessageBuilder>org.serviio.upnp.service.contentdirectory.PacketVideoDLNAMessageBuilder</ContentDirectoryMessageBuilder>
<Transcoding>
<!-- Transcode h264 videos with profile level > 4.1 to mpegts with ac3 audio -->
<Video targetContainer="mpegts" targetVCodec="mpeg2video" targetACodec="ac3" maxVBitrate="20000">
<Matches container="mp4" vCodec="h264" profile="high" levelGreaterThan="4.2" />
<Matches container="mp4" vCodec="h264" profile="main" levelGreaterThan="4.2" />
<Matches container="matroska" vCodec="h264" profile="high" levelGreaterThan="4.2" />
<Matches container="matroska" vCodec="h264" profile="main" levelGreaterThan="4.2" />
</Video>
<!-- remux VORBIS/FLAC/LPCM in MKV/MP4 to AC3 -->
<Video targetContainer="mpegts" targetACodec="ac3">
<Matches container="matroska" vCodec="h264" aCodec="flac" />
<Matches container="matroska" vCodec="h264" aCodec="vorbis" />
<Matches container="matroska" vCodec="h264" aCodec="truehd" />
<Matches container="mp4" vCodec="h264" aCodec="lpcm"/>
<Matches container="mp4" vCodec="h264" aCodec="aac"/>
<Matches container="3gp" vCodec="h264" />
</Video>
<!-- Remux MPEG-TS with no transcoding -->
<Video targetContainer="mpegts">
<Matches container="mp4" vCodec="h264" />
<Matches container="matroska" vCodec="mpeg2video"/>
</Video>
<!-- Remux WTV files to MPEG-PS with no transcoding-->
<Video targetContainer="mpeg">
<Matches container="wtv" />
</Video>
<!-- unsupported codecs will be transcoded into mpeg-ts, mpeg2 video and ac3 audio -->
<Video targetContainer="mpegts" targetVCodec="mpeg2video" maxVBitrate="17000" targetACodec="ac3" aBitrate="384" forceInheritance="true">
<Matches container="avi" />
<Matches container="mp4" vCodec="mjpeg" />
<Matches container="mp4" vCodec="mpeg4" />
<Matches container="mpeg" vCodec="mpeg1video" />
<Matches container="matroska" vCodec="mpeg4" />
<Matches container="asf" />
<Matches container="flv" />
<Matches container="ogg" />
<Matches container="3gp" />
</Video>
<!-- unsupported audio will be transcoded into lpcm audio -->
<Audio targetContainer="lpcm">
<Matches container="flac" />
<Matches container="ogg" />
<Matches container="asf" />
<Matches container="adts" />
</Audio>
</Transcoding>
</Profile>

It does work but the main issue is the quality of the picture when playing the AVIs. If I use a Mac or PC and play them directly off the NAS where they are stored, quality is great.
When Serviio kicks in and transcodes them so the TV can play these, I can definitely see lots of artifacts on the picture.
What can be done to get the maximum transcoding quality? I tried the setting on the Serviio console and same thing.
There must be something I can set on the profile to maximize the quality or to tell it to keep the original resolution (it seems like it is using much lower resolution when transcoding).
The machine where this is running has TONS of power to spare so whatever setting you think will bog down this PC will not do anything I am sure. :D
It has two Xeon CPUs with 4-cores each, SSD storage and 32GB of RAM. Running either Windows 7 or Mac OSX 10.7.X.

Please help Obi Wan.

Re: AVI Transcoding Quality

Is this custom profile or are you using an older version of Serviio?

Try one of the standard Panasonic Viera profiles that comes with the latest version of Serviio and see if that improves AVI playback. Which standard Viera profile to use depends on what model Viera you have - it should auto detect (you may have to remove your device and then refresh for it to auto-detect).
