DivX file size an quality

[rouch]

I´m converting some .avi files to DivX but I can´t reach the quality and size I want

I´ve downloaded some TV series from the web. 48 munites with good quality using 350 MB of space

This is what I´m doing:

1- Get the .avi file from my DV video camera

2- Convert it with WinAviVideoConverter or River Past Video Cleaner Pro to DivX

I tried many configurations of the DivX Pro 5.1.1 Codec:

Gerneral

- Performance / quality: Slowest

- Variable bitrate mode: 1-pass

- Encoding bitrate: 8 Mbps (with less Mbps around 5 I get poor quality)

Video - Advanced

- Source Interlace: Encode as progressive

- Max keyframes Interval: 300 frames

I´d like to have 48 minutes of video in 350 MB with good quality...

If someone knows what I´m doing wrong please tell me

Thank you, Rouch

Try convert with AutoGk, set it to 350MB and use a low resolution like 320x240 and encode (if you want higher resolution you need to do a good deinterlacing). But you wont get same quality as from good progressive dvd sources.

and this is no DVD to AVi, moving you.

HI Rouch,
Usually the audio track contributes to large file sizes, try using virtualdubmod with the following settings.

Change the video size to something similar to the downloads you have done eg: widescreen 512x288, you may need to use a de-interlace filter set to blend and precise biliner.

go to your audio streams and select the audio track and set to full processing then go to compressions and choose MP3 @ 128kbs

Now you can save it as divx, first do a 1st multi pass, then 2nd multi pass which will refer to the 1st pass stats for best and smallest file size.

You will not be able to get as good results with handheld camcorder footage compared to a commercial DVD rip. All the shaking makes the video less compressible. Also, consumer camcorders have noisy CCDs which make the video less compressible.

Pass the stuff through some noise filters may help.

In my experience, if you filter enough to make a significant difference in compressibility, the video will be damaged.
