Help to correct my xvid setting for right playback on portable

[Irakli]

Hi, everyone
Recently I received an MP3 player as present which plays video as well. It comes with its own video convertion software called AviConverter.
Here I uploaded video converted by this program which works on my player:

As you can see, video quality isn't great: I am not referring to blockiness (since this will unlikely be noticed on my player's 3" screen) but to way this program converts framerate to 20fps (by dropping frames which indeed does not look very good).

That's why I try to encode video in "manual" way (dgindex->avisynth->megui. So far I found that for video to be compatible with player, it should be:
20fps
Xvid simple profile, hence no bframes, no qpel, h263 matrix
MP2 audio (128kbps cbr)
Avi as a container
However, after encoding with these settings the player does not want to play my video.

So, can I please ask you to help me by analizing my uploaded video (which is compatible with the player) and suggesting what should I change or add in my "manual" settings so that output can be playable on my MP3 player?

Thanks for any help,
Irakli

A brand and model name of your MP3 or MP4 player will help.
You should try GSpot for more info on your AVI file.

It is Thomson A1 (made for China so I even cannot read the instruction to understand which file types are supported).

As for GSpot, I will try it and report my findings soon.

OK, I finally had time to finish with GSpot. Below I uploaded two screenshots: one for the video that is playable on the device (converted using supplied software), another for unplayable video.

I wonder why the second file is unplayable although video&audio settings are identical for both files (except small difference in bitrate). Does it have something to do with the differences in the avi containers' structure between these 2 files? :confused:

Could you please help me to resolve my problem.

Thanks,
Irakli

P.S.: the convertion software supplied with the device seems to be based on mencoder.

Have you try MP3 audio instead of MP2?

[Irakli]

No, but I suppose this does not really makes sense since playable avi file contains mp2 audio, so changing audio in unplayable file to mp3 could mean going even further from 'playable' settings.

test.avi has a typical "standard" PAR (pixel aspect ratio) of 1.00 (ie square pixels), yeilding a 4:3 DAR (display aspect ratio).

test3.avi has a PAR of "~4:3" - ie it is telling the device to stretch the image horizontally to "~16:9" DAR.

Does your device have a 16:9 display? Does it support 'PAR signalling' and non-square pixels?
