Encoding in XVID causes horizontal stripes on standalone player

[deadp0et]

Hi all.

I use my standalone player to play AVI vids taken from the net and never had any problem. Recentely I had to encode my own videos, but I keep running into this problem: whenever my standalone player plays my videos they present a lot of dancing horizontal stripes. Here are some photos of them:



The stripes DO NOT show up if playing the videos on my computer, for example with Windows Media Player or VLC. They just show up on my standalone player.

I tried to encode my videos using ffdshow, then I tried XVid, and I tried to fiddle with their settings, but all to no avail. The stripes are always there. Sometimes I can get rid of them by clicking several times on the play/pause button of the standalone player, sometimes they just won't go away.

They DO NOT appear if playing a third-party vid, for example AVI videos downloaded from the net

Any suggestion on how to encode my videos to get rid of them?

Thanks
Davide

I already tried to disable the Packing bitstream option but the stripes still show up.

[poisondeathray]

maybe your standalone has problems with the width > 720 ? Try a small test encoding to smaller dimensions

[deadp0et]

No, I have already tried encoding a file whose width is 624 and the stripes did show up all the same.

[jagabo]

Are you sure? I don't see anything else unusual. The only other major difference is the 25 fps vs 23.976. But every player I've seen plays both.

Writing library : XviD 64

What is this?

Try 32bit xvid in vdub

[deadp0et]

Are you sure?

No I was mistaken. You are right! The video I thought was 624 pixel wide, had actually a width of 852.

I think you nailed it!

Tomorrow I'll make a test reducing the width of my files and let you all know.

Thanks
Davide


PS: I don'k know why that XviD 64 tag, that was actually the 32bit vdub

[deadp0et]

Ok made a test and encoded one file < 720 width.
Then played on my standalone player.
Result: no stripes whatsoever! :P

Thanks guys, thanks for your help.

Ciao from Italy,
Davide

[jagabo]

Glad it worked out. That was a very unusual symptom though.

@deadpOet

Glad to know that you figured-out and it worked.
The problem was
Width : 864 pixels <----- should be equal or less than 720px for stand-alone DVD players.
Height : 480 pixels <----- should be equal or less than 480px for stand-alone DVD players.

hope you are in Italy which follows DVB-T or DVB-T2 standards for bradcast.
so your final encode must not exceed 720X480i@29.97FPS NTSC-SD SPECS for DVD Players.
and must not exceed 1920X1080i@30.00FPS NTSC-HD SPECS for BD Players.
PC Monitor will play and rescale anything within certain limits.

[deadp0et]

Ok. Thanks again.

Most player can handle up to 576 lines tall because that's the PAL standard. A quick experiment will tell you for sure about your player.
