Problem with picture

[Xload]

I have problem with picture, i use virtualdub from XviD4PSP 5 apps and xvid video codec, i encoding 1st pass and 2nd pass , i have installed: ffshow, avisynth, K-lite codec, matroska pack, haali media splliter

the picture is like this, what it wrong or what missing on my computer?





tnx for help

Bitrate too low ? Try setting the Xvid encoder to do one pass, CQ = 3.

Also, select MPEG quantization type instead of H.263

I have and bitrate is more than 2000kb/s

Get rid of K-Crap.

[Xload]

i deleted k-lite codec and i'm encode only one pass but picture is not better

[davexnet]

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.

Try encode with VidCoder to mp4 or mkv
and see result in VLC player
what the source DVD, avi... ?

[Xload]

source is bluray (MKV)

That's too low for 1280x532 and fast action material. Do what davexnet suggested, use target quantizer mode at 3.

[Xload]

use target quantizer mode at 3.

This is in Zone options, right?

[hello_hello]

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".

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

source is bluray (MKV) from PublicHD

PublicHD is a torrent site. You do realize discussion of warez is against forum rules, right?

[Xload]

I didn't know, sorry

[roma_turok]

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

Now is 3,46 Gb, before 2,58 Gb
I want small size, with minimum loss of quality.

[roma_turok]

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

I am. Good program, I preview the output video file and the picture is great. Tomorrow I do encoding video file with H264 codec.

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

[roma_turok]

If you set to normal preset with constant quality 20 ?
same problem?

[Xload]

yes

[roma_turok]

I think its the source not best quality
can you post picture of same frame of the source?

[Xload]

it's a little better

[roma_turok]

You have input resolution 720p not 1080p
its AVI file with Xvid codec?
or mkv / mp4 file?
what size of the source file?

[jagabo]

Some movies require more bitrate than others.
