Encoded DivX play so slow

[cniedzi]

Dear Sirs,
I'm an owner of DV Sony camera and Pinnacle DV card. I would like to use DivX 5.0.1 Pro codecs to encode my videos. Everything goes ok, but when I'watching produced AVIs, the compressed videos go too slowly and audio track overtake video. And this is with other software, for example VirtualDub, or Flask. I have Pentium III 450 with 512 MB of RAM and Voodoo3/TVOut.
What's wrong?

What resolution are you encoding at ?.

With only 450 mhz it might be that you processor is too slow.

In WindowsMediaPlayer6.4 select File->properties->Advanced->'divx decoder filter'->properties->'Quality settings'

Select 'overlay extended mode' and 'yuv extended mode'

Restart wmp 6.4 and go into

File->properties->Advanced->'divx decoder filter'->properties

and move the quality slider to the left.

If the doesn't solve your problems, you have to encode at a lower resolution, or the clip has been encoded incorrectly.

I encode to 720x528 (or something like this) resolution.

And when I watch other ripped DVDs everytjing goes OK.

This is way too much for a 450 mhz P3.

At 720*528 encoded with divx5 ?

Are you using B-frames, GMC or Q-pel for encoding ?, this will futher increase the cpu power needed for decoding.

Re: My video goes too slow

I don't use additional options in 5.0.1 Pro - only standard settings.

Would you be so kind and send me settingss for DivX 5.0 Pro codecs for PIII450, that enable me to rip DVD at good quality (like mostly DVD's rips over the world)?
Maybe lower resolution will be enough to watch rips on full screen?

For 4:3 movies you should not go above 576*432, with 16:9 movies you should be able to do 640*368.

When zooming to full screen on a high reslolution monitor, divx video often looks rather poor, this is, at least in part, due to poor quality resizing. There is a bicubic resize filter floating around somewhere, but of course this is also very cpu intensive. I think the best thing you can do is to set the resolution on your desktop as low a possible.

Movie goes so slow

Thx Buddy for your help-I'll try your advices.
Am I right, is the problem only with playing on my PIII450 (not with encoding)? When I'll use faster PIII1000+ to watch this high resolution DivX movie, then everything will be fine?

[khp]

Yes exactly.

Although sync issues can also be caused by mistakes in the encoding process, I'am pretty sure your problems have been playback related.

But feel free to ask againg, if you continue to have problems.

My video goes too slow

Thx buddy, your advices helped me.
I have another one question to you.
Could you explain how can I encode DivX with 2-passes option. I have heard that it produces the best quality.

To encode in 2-pass mode, first encode once using '2-pass, first pass', this will produce an invalid avi file, and a log file.

Then you encode again, using the exact same settings, except that you switch to '2-pass, second pass' in the codec. This will then use the logfile and create the real avi file.

Have I to create in 1-pass MV file?

In 2-pass have I to show the avi file from 1-pass encoding?

No, you don't have to use the mv-log file feature, but it will make the second pass slightly faster.

No, the avi file created in the first pass is not used for anything, it's OK to overwrite it in the second pass.

[khp]

Of course if you use the mv-log file feature, it must be enabled for both the first and second pass.
