Divx Movie Plays With Bad Pixelation On Xbox360
« on: January 06, 2008, 02:16:00 PM »

How exactly are you streaming it? TVersity, Transcode360, Xbox 360 Dashboard?

Knowing that will help. As well, what is the bitrate of the resulting DivX?

Divx Movie Plays With Bad Pixelation On Xbox360

PIXELATION on xb360 stream but good when viewed on PC
Video: DivX 5 1280x536 23.98fps 4790Kbps [Video 0]
Audio: PCM 44100Hz stereo 1411Kbps [Audio 1]

Transcoded to WMV: Runs GOOD on both xb360 stream or viewed on PC
Video: Windows Media Video 9 1280x536 23.98fps 3704Kbps [Raw Video 1]
Audio: Windows Media Audio 48000Hz stereo 64Kbps [Raw Audio 0]


When I view the divx streamed to the xb360, the video is smooth with no stalling (the buffering bar never appears). I just get bad pixelation.

I then tried another experiment - to manual transcode a 720p mov file from Apple Trailers instead.
Original MOV (from Quicktime's Movie Info): Can't seem to play this file on xb360 - that's a separate problem I have, but that's not my concern now
Video: H.264 1264x720 29.99fps
Audio: AAC 44100Hz Stereo
Data Rate: 815.48Kbps

DIVX attempt#1:  PIXELATION on xb360 stream but good when viewed on PC
Video: DivX 5 1264x720 30.00fps 2945Kbps [Video 0]
Audio: MPEG Audio Layer 3 44100Hz stereo 128Kbps [Audio 1]

DIVX attempt#2:  PIXELATION on xb360 stream but good when viewed on PC
Video: DivX 5 1264x720 30.00fps 5840Kbps [Video 0]
Audio: PCM 48000Hz stereo 1536Kbps [Audio 1]


What I was doing in both DIVX attempts above was to experiment with different audio encoding & different quality levels, but I still get the pixelations.

Now here's the funny thing. I have this native DIVX file:
Video: DivX 5 1280x720 25.00fps 6101Kbps [Video 0]
Audio: Dolby AC3 48000Hz 6ch 384Kbps [Audio 1]


It plays fine, with HD quality on both xb360 stream & PC... so what gives?? I'm really stumped!  blink.gif  blink.gif
