Video Encoding quality very poor Possible Causes?

Energize · 18 Mar 2006 at 00:17

Im using virtual dub, to re-encode stuff I recorded off the tv im mpeg 2 but it keeps messing it up. Im using the divx 6 codec @ 1Mbps on the balanced setting, with quarter pixel and gmc enabled and masking enabled, but the video gets destroyed. Any ideas why?

Original

After encoding.

I think that's just the way high compression video works, especially on videos with lots of movements you can see the quality of the picture struggle.Does it look ok for low movement scenes with that compression?

No it still doesnt look normal. Ive seen 16:9 films look as good as the dvd version at xvid 1.3mbps so somethings wrong.

Use XviD codec, DivX sux.

You could also try Xvid and have if you look into the properties when setting up the encoding it has a decent calculator for working out bit rates.

Also it kind of looks like the resolution is quite low or something, what are you setting it to?

The res is the same as the pictures 960x544.

Xvid is much better actually.

Use auto gordian knot, converts stuff to divx with a couple of clicks and they all come out fiiiiinnnnneeee :cool:

Also see dvrhelp.com or afterdawn or doom9 for simple encoding guides, its not rocket science.

I can tell its not caused by a low bitrate because it has the same pixelation all the time, the picture is perfect apart from the squares when things move it doesnt get any worse.

If you use GSpot Codec Information, click on the encoded file then take a screenshot of the information. Might be able to see if there is anything wrong with it.

Have you tried using a different encoder such as WinAvi? I assume the video is MP4 and the audio is MP3?

I found the problem, it was because the motion precision was set too low.

Nero's MP4 > Xvid/Divx

Xvid & DivX are so last year

If neros mp4 was better everyone would be using it for downloaded films but everyone is using xvid. In my experience neros codecs have been pretty poor, espically the dvd one which looked awfull, besides neros mp4s wont play on a dvd player like xvid will.
