Any Solutions for Blue Skin Divx playback?

[dporvin]

I've seen posts on this but no solutions yet. I have some downloaded AVIs that I would like to play on my Philips 642. They play OK on my computer, but the audio is way over-modulated and skintones are blue on the DVD player. I opened the files using various apps (on a Mac w/System 10.4) and got the following info:

VLC
VideoX50, 512x408, 25fps
Audio:mpga,44.100,128kb/s
------------------
ffmpeg
Video:mpeg4, yuv420p, 512x408
Audio:mp3,41000,128kb/s
-------------------
D-Vision
Videoivx4, 512x408, 817k/sec, 25fps
Audio:mp3,441000,128kb/s,stereo,CBR

I think the size is supposed to be 512x384 and maybe they were ripped off the 4x3 DVD incorrectly. Or are these from a PAL DVD? Is there a way to fix these for my DVD player without losing too much quality? I have ffmpeg and D-vision - what settings should I use to re-encode?.
Thanks!

Press System/Menu twice on the remote while playing. That should clear up the colors. The problem is caused by the use of custom matrices in the MPEG4 compression.

Thanks for the replies. The system/menu button trick doesn't fix it. I'll check out the provided link as well. Thanks Again!

I tried all those "tricks" with the menu, none of them worked. The only thing that worked for me was changing the resolution (was 544 x 416, changed to 352 x 240). I saw in another thread about this that "416" seemed to be the magic bad number, for some reason. Maybe with PAL encodes, 408 is that problem number.

Good luck.

The problem i belive is that the movie was done with the q-pel setting on the dvd-642 doesnt handle this option to well. However this can be fixed.

Option 1: you can do is run through divx converter this well work but can be time consuming as it doesnt convert too fast and there well be some quality loss most likely. But you can set multiple files and just let it go overnight. For every one hour of video figure about 2 hours for the converter. So 2 hour movie 4 hours to fix it. Could be faster if you have a realy fast comp.

Option 2: you can use Nero Digital convert movie to nero digital then fix the file so your dvp642 well think its a divx file. I made a guide for that and you can find that here:

Since you wont be converting from dvd you can just skip those parts of the guide and just use the part of the guide that well show you how to fix the file.. Either option well work but option 2 well cut your time buy at least half.. and you should have no quality loss

Interesting. I have a DVP 642 here right now so I thought I'd try it out. Indeed, it doesn't like 544x416 (NTSC). The colors are all wrong. I don't have the remote control so I couldn't try the System/Menu button trick. Other sizes played proplerly, including 544x408.

It's definitely not qpel...anything encoded with qpel will not play at all. You'll just get bounced right back to the menu, or get an error.

Jagabo- was that 408 encode you tested PAL or NTSC? I don't know why that would matter, but maybe it does.

I started with a 640x480 29.97 fps Xvid AVI and made two short test XVID AVI files, one at 544x416, the other at 544x408, both at 29.97 fps (no GMC, no QPEL). I might get a chance to try 25 fps later today. But I'll still be watching them on an NTSC TV at 29.97 fps. I don't have a PAL TV.

I think I am going to post a separate topic question on this, but is it the player only? can it have to do with output cable?

I have a few self authored dvds of home movies. they are just dvdshrink authored with NTSC and PAL vobs as different titles.

I have run these off my DVD player (panasonic) to my samsung lcd TV via component everything is fine. when I run it off of S-Video off the same setup the PAL shot titles are shot to heck colorwise with all heavy blue tint on the skin.

This came up because I had been using component of the ddv player but with my new cable box I am using the componenet out on the cable box and s-video on the dvd player. (the lcd has 1 rf, 1 composite, 1 s-video, on component and one dvi (which is not HDCP and so no good for the cable box).
