Bitrate too low ? Try setting the Xvid encoder to do one pass, CQ = 3.
-
Also, select MPEG quantization type instead of H.263
-
One pass at a constant bitrate is always liable to give the poorest results if the bitrate is on the low side.
Either try CQ encoding (if it's available), or 2-pass encoding. -

It's a single pass encoding method called constant quantizer, or target quantizer. The bitrate will be whatever it needs to be. A Constant quantizer of 2 is basically maximum quality for Xvid. The higher the quantizer the lower the quality. 3 is probably a reasonable compromise between quality and file size. The resulting bitrate will also be a good indication of the minimum bitrate you should be using for 2 pass encoding.
Instead of configuring Xvid for 1st pass or 2nd pass, try "single pass". -
Set the "Encoding Type" to "Single Pass". Press the "Target Bitrate (kbps)" button to make it say "Target Quantizer". The default quantizer is 4. 3 will look better. 2 or 1 even better -- but file sizes starts ballooning up. You can use non integer values like 2.5 too.

i encoding 2passes with target quantier 3, picture is much better, but the file is for 1/3 bigger then before
tnx for helping -

What size is now?
What purpose of re-encoding? to make smaller size file? -

I want small size, with minimum loss of quality. -
As I write before: encode with VidCoder to mp4 or mkv
press on Preview button to encode 1 min, to see quality example
in Video tab set size:

You can't have both. Switching to h.264 will get you better quality at the same size.
I don't know how encoding with this codec in VirtualDub. -
Download program VidCoder instead-> https://www.videohelp.com/download/VidCoder-1.4.25-x86.exe

hey guys
Again I have problem witch picture, when i encoding bluray is output picture very bad like this, the input resolution is 1080p output is 720p and i have more than 2500 kb/s but picture is too bad
i don't have these problems with picture, before I formatted the computer, despite smaller bitrate (2000kb/s)
please help -
If you set to normal preset with constant quality 20 ?
same problem? -
I think its the source not best quality
can you post picture of same frame of the source? -
You have input resolution 720p not 1080p
its AVI file with Xvid codec?
or mkv / mp4 file?
what size of the source file?
